AB  - We have synthesized 22 C-1 functionalized-N-aryl-1,2,3,4-tetrahydroisoquinoline derivatives showing biological activities towards cholinergic enzymes. Synthesis was performed using visible-light-promoted photo-redox chemistry, starting from a common intermediate, and the application of this synthetic methodology drastically simplified synthetic routes and purification of desired compounds. All synthesized derivates were divided into four groups based on the substituents in the C-1 position, and their inhibition potencies towards two cholinergic enzymes, acetyl- and butyrylcholinesterase were evaluated. Most potent derivatives were selected, and kinetic analysis was further carried out to obtain insights into the mechanisms of inhibition of these two enzymes. Further validation of the mode of inhibition of cholinergic enzymes by the two most potent THIQ compounds, 3c and 3i, was performed using fluorescence-quenching titration studies. Molecular docking studies further confirmed the proposed mechanism of enzymes’ inhibition. In silico predictions of physicochemical properties, pharmacokinetics, drug-likeness, and medicinal chemistry friendliness of the selected most potent derivatives were performed using Swiss ADME tool. This was followed by UPLC-assisted log P determination and in vitro BBB permeability studies performed in order to assess the potential of the synthesized compounds to pass the BBB.

AB  - The catalytic degradation of hazardous organic contaminants in industrial wastewater is a promising technology. Reactions of tartrazine, the synthetic yellow azo dye, with Oxone® in the presence of catalyst in strong acidic condition (pH 2), were detected by using UV–Vis spectroscopy. In order to extend the applicability profile of Co-supported Al-pillared montmorillonite catalyst an investigation of Oxone® induced reactions were performed in extreme acidic environment. The products of the reactions were identified by liquid chromatography–mass spectrometry (LC-MS). Along with the catalytic decomposition of tartrazine induced by radical attack (confirmed as unique reaction path under neutral and alkaline conditions), the formation of tartrazine derivatives by reaction of nucleophilic addition was also detected. The presence of derivatives under acidic conditions slowed down the hydrolysis of tartrazine diazo bond in comparison to the reactions in neutral environment. Nevertheless, the reaction in acidic conditions (pH 2) is faster than the one conducted in alkaline conditions (pH 11). Theoretical calculations were used to complete and clarify the mechanisms of tartrazine derivatization and degradation, as well as to predict the UV–Vis spectra of compounds which could serve as predictors of certain reaction phases. ECOSAR program, used to estimate toxicological profile of compounds to aquatic animals, indicated an increase in the harmfulness of the compounds identified by LC-MS as degradation products from the reaction conducted for 240min. It could be concluded that an intensification of the process parameters (higher concentration of Oxone®, higher catalyst loading, increased reaction time, etc.) is needed in order to obtain only biodegradable products.

AB  - The title compound (Figure 1) was prepared from cyclohexanone in the Bucherer-Bergs reaction, followed by acylation of the obtained spirohydantoin. Formation of the crystal structure of this compound was analysed in terms of a number of simple dimeric motifs which are associated with different intermolecular interactions. The crystal structure retains the motif commonly found in hydantoin derivatives, where two molecules related by inversion are linked by a pair of N–H O hydrogen bonds. This motif is involved in two types of double chains, whichfurther form a layer (Figure 2). Intermolecular interactions were also investigated using Hirshfeld surface analysis and 2D fingerprint analysis. Weak C–H⋯O interactions together with thedispersion interactions (π-π and hydrophobic) as the source of attraction are identified in this crystal structure.Crystal data: C19H24N2O3, Mr = 328.4, triclinic system, space group P–1, a = 6.2810(2), b = 12.0586(4), c = 12.1852(5) Å, a = 77.624(3), β = 81.039(3), γ = 79.111(3) °, V = 878.81(6) Å3, Z = 2, F(000) = 352,ρx = 1.380 g cm–3, µ(MoKa) == 0.084 mm–1.

AB  - Fluorapatite (FAP) crystals have drawn significant interest over the last few decades as important hosts matrix for optically active trivalent rare earth ions, due to the strong crystal field splitting and large transition cross-sections. Nano-sized FAP particles doped with rare earth ions have been extensively studied as luminescent materials for biomedical applications for cell labeling and bioimaging, as well as antimicrobial agents for therapeutics.Fluorapatite nanoparticles doped with praseodymium ions (Pr3+) were prepared by the co precipitation method and characterized. The different number of Pr3+ (4f2) transitions in the ultraviolet and visible parts of the spectrum was investigated by photoluminescence spectroscopy. Multivariate Curve Resolution–Alternating Least Squares (MCR-ALS) analyses of fluorescence spectra and ab initio calculation indicated that Pr3+ ions are preferentially substituted Ca2 (6h) sites in FAP lattice. In addition to the substitution of cations, there is also the substitution of anionic species such as OH-, CO32-, and NO3-, which are confirmed by the CHNS method. The obtained samples were tested as bioimaging and antibacterial agents and can potentially be used for further biomedical research.

In addition to the substitution of cations, there is also the substitution of anionic species such as OH-, CO32-, and NO3-, which are confirmed by the CHNS method. The obtained samples were tested as bioimaging and antibacterial agents and can potentially be used for further biomedical research.",

AB  - The hierarchical development of the crystal structure of racemic 3-(4-methoxybenzyl)-6,7- benzo-1,3-diazaspiro[4.5]decane-2,4-dione was analyzed through cooperativity of various homo  and heterochiral dimeric motifs associated with the presence of different intermolecular  interactions, namely strong N–H···O and weaker C–H···O, C–H···π and PILOs.1 Although a  bigger number of the contacts in the environment of the tetralin unit results from its larger  contact surface, the 4-methoxybenzyl unit provides a greater contribution to the overall  stabilization. In addition, the investigated compound is identified as a potential inhibitor of  kinase enzymes and AG protein-coupled receptors, with a slightly higher affinity for the later  enzyme. An analysis of the nature of the amino acid residues around the tetralin and 4-methoxy  benzyl units revealed that interactions with nonpolar groups are the most prevalent and even  more numerous than interactions with other amino acid residues (polar, positive and negative).

AB  - The contamination of water with chromium is a global issue that is especially severe in developing countries with intensive mining and heavy industry (South Africa, Pakistan, and India) [1,2]. Trivalent Cr(III) and hexavalent Cr(VI) are the most common forms found in effluent water. Whereas trivalent chromium is a micronutrient (25–35 g/day) involved in the metabolism of lipids and carbohydrates [3,4], hexavalent chromium is exceedingly toxic, teratogenic, and mutagenic. Particularly concerning are its high solubility in water, mobility in detritus, and potential for bioaccumulation in living tissues. Due to these factors, hexavalent chromium has been the subject of numerous studies, especially its removal from effluent [5,6]. These studies have demonstrated that sorption is a highly effective and relatively simple technique for chromium removal from wastewater. In terms of this, magnetic heavy metals nanosorbents derived from inorganic compounds and polymers [7-9] are incredibly intriguing, because they could have been readily extracted from the mixture using an external magnetic field. The sorption investigation of hexavalent chromium in aqueous solutions on the magnetic aminofunctionalized polymer nanocomposite based on glycidyl methacrylate, m-PGMA revealed its highly selectivity and efficiency. [10,11]. The binding mechanism of hexavalent chromium ions onto m-PGMA was investigated using kinetic, equilibrium, and thermodynamic experiments as well as molecular modeling techniques (theoretical quantum-chemical calculations) [12-15]. It was observed that the process occurs in two phases. In the first phase, electrostatic interactions attract hexavalent chromium ions to the surface of the sorbent via the active sites (amino and APTMS groups). Cr(VI) is then converted to Cr(III) ions, which can coordinate with amino or hydroxyl groups on the surface of the sorbent [16]. The trivalent chromium ions that persist in the solution or on the surface of the sorbent are less hazardous than the initial hexavalent form. The application of m-PGMA sorbent enables the transformation of the toxic form of chromium into a less hazardous form, which is significant due to the possibility of sorbent regeneration and the subsequent processing of the solution following sorption.

AB  - Platinum-based drugs are widely recognized efficient anti-tumor agents, but faced with multiple undesirable effects. Here, four dinuclear platinum(II) complexes, [{Pt(1,2-pn)Cl}2(μ-pydz)]Cl2 (C1), [{Pt(ibn)Cl}2(μ-pydz)]Cl2 (C2), [{Pt(1,3-pn)Cl}2(μ-pydz)]Cl2 (C3) and [{Pt(1,3-pnd)Cl}2(μ-pydz)]Cl2 (C4), were designed (pydz is pyridazine, 1,2-pn is ( ±)-1,2-propylenediamine, ibn is 1,2-diamino-2-methylpropane, 1,3-pn is 1,3-propylenediamine, and 1,3-pnd is 1,3-pentanediamine). Interactions and binding ability of C1–C4 complexes with calf thymus DNA (CT-DNA) has been monitored by viscosity measurements, UV–Vis, fluorescence emission spectroscopy and molecular docking. Binding affinities of C1–C4 complexes to the bovine serum albumin (BSA) has been monitored by fluorescence emission spectroscopy. The tested complexes exhibit variable cytotoxicity toward different mouse and human tumor cell lines. C2 shows the most potent cytotoxicity, especially against mouse (4T1) and human (MDA-MD468) breast cancer cells in the dose- and time-dependent manner. C2 induces 4T1 and MDA-MD468 cells apoptosis, further documented by the accumulation of cells at sub-G1 phase of cell cycle and increase of executive caspase 3 and caspase 9 levels in 4T1 cells. C2 exhibits anti-proliferative effect through the reduction of cyclin D3 and cyclin E expression and elevation of inhibitor p27 level. Also, C2 downregulates c-Myc and phosphorylated AKT, oncogenes involved in the control of tumor cell proliferation and death. In order to measure the amount of platinum(II) complexes taken up by the cells, the cellular platinum content were quantified. However, C2 failed to inhibit mouse breast cancer growth in vivo. Chemical modifications of tested platinum(II) complexes might be a valuable approach for the improvement of their anti-tumor activity, especially effects in vivo.

AB  - In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated. Uniform nanopowders were synthesized by precipitation reaction followed by centrifugation and systematically characterized by XRD, FTIR, SEM–EDS, TG and PL methods. XRD analysis revealed the formation of hexagonal FAp crystals, and FTIR spectra indicate the presence of nitrate (NO3−) and carbonate (CO32−) species. SEM analyzes confirm agglomerates composed of irregular nanometer-sized spheres. Emission of FAp nanopowder occurred in the violet-blue region of the visible part of the spectrum, with redshift to the blue-green color region when Pr3+, NO3− and CO32− co-doped in the lattice. Analysis of luminescence spectra by MCR-ALS method extract three fluorophores from the PrNCFAp sample and showed simultaneous existents of emission-reabsorption-emission between dopants in FAp lattice. Antibacterial activity against pathogen Staphylococcus aureus was investigated before and after treatment of nanopowders by UVA radiation of 365 nm. Nanopowders irradiated with UVA compared to non-irradiated reduced Staphylococcus aureus by 84.9% for PrNCFAp and 33.3% for FAp in the first 0.5 h of contact, and 76.1% and 42.9% after 24 h of contact. In addition, the obtained luminescent nanomaterials showed a low degree of hemolytic activity and could potentially be candidates for further research in dentistry.

AB  - The present study describes representative examples of supramolecular arrangement of 5-phenylhydantoins achieved through various N–H⋯O hydrogen-bonding patterns. Four derivatives, 5-ethyl-5-(4-methylphenyl)hydantoin (1) and three 5-methyl-5-(3- or 4-substituted phenyl)hydantoins (2–4), were synthesized by the Bucherer–Bergs reaction and their crystal structures were determined by the single crystal X-ray diffraction method. A racemate, racemic hydrate and conglomerate as outcomes of crystallization from racemic solutions were found here. The crystal structures were firstly subjected to Hirshfeld surfaces analysis. The development of hydrogen bonding driven two-dimensional assemblies such as tapes, ribbons and sheets was further analysed using DFT calculations in terms of contribution of dimeric motifs as building blocks, which are associated with the presence of intermolecular interactions. To explore qualitative correlations between intermolecular interactions determining the crystal structures of the investigated compounds and those underlying their biological activity, we performed a docking study on the neuronal voltage gated sodium channels, matrix metalloproteinase 12 and aldose reductase. The supramolecular profiles of the investigated compounds are also maintained in biological systems and as such are responsible for differences in their biological activities.

AB  - The numerous side effects of platinum based chemotherapy has led to the design of new therapeutics with platinum replaced by another transition metal. Here, we investigated the interactions of previously reported copper(II) complexes containing S-isoalkyl derivatives, the salicylic acid with guanosine-5′-monophosphate and calf thymus DNA (CT-DNA) and their antitumor effects, in a colon carcinoma model. All three copper(II) complexes exhibited an affinity for binding to CT-DNA, but there was no indication of intercalation or the displacement of ethidium bromide. Molecular docking studies revealed a significant affinity of the complexes for binding to the minor groove of B-form DNA, which coincided with DNA elongation, and a higher affinity for binding to Z-form DNA, supporting the hypothesis that the complex binding to CT-DNA induces a local transition from B-form to Z-form DNA. These complexes show a moderate, but selective cytotoxic effect toward colon cancer cells in vitro. Binuclear complex of copper(II) with S-isoamyl derivative of thiosalicylic acid showed the highest cytotoxic effect, arrested tumor cells in the G2/M phase of the cell cycle, and significantly reduced the expression of inflammatory molecules pro-IL-1β, TNF-α, ICAM-1, and VCAM-1 in the tissue of primary heterotopic murine colon cancer, which was accompanied by a significantly reduced tumor growth and metastases in the lung and liver.

AB  - The hydrolysis of N-acetylated L-methionylglycine dipeptide (Ac-L-Met-Gly) in the presence of dinuclear platinum(II)-aqua complexes with general formula [{Pt(L)(H2O)}2(μ-1,5-nphe)]4+ (1,5-nphe is 1,5-naphthyridine; L is bidentately coordinated ethylenediamine (1w), (±)-1,2-propylenediamine (2w) and 1,3-propylenediamine (3w)) is described in detail. The hydrolytic activity of these complexes was monitored by 1H NMR spectroscopy, which confirmed the regioselective cleavage of the Met-Gly-amide bond in this peptide. Quantum-chemical calculations revealed the primary reaction path with coordination of dipeptide via the terminal amide nitrogen of methionine followed by its coordination for the sulphur atom, in which the decomposition of the resulted platinum(II)-dipeptide complex and the coordination of its glycine residue precedes the hydrolytic cleavage of the Met-Gly amide bond. In the secondary reaction path, in which Ac-L-Met-Gly is coordinated via the methionine sulphur atom, the decomposition of the starting [{Pt(L)(H2O)}2(μ-1,5-nphe)]4+ complex is followed by the regioselective hydrolysis of the investigated dipeptide. The binding affinity of the chloride derivatives of the corresponding dinuclear platinum(II)-aqua complexes, [{Pt(L)Cl}2(μ-1,5-nphe)]2+ (1–3) towards the human serum albumin (HSA), a transport protein, was investigated using electronic absorption and fluorescence emission measurements, and results indicated the static interactions between these complexes and HSA. A docking study revealed a unique binding site on HSA, based on the electrostatic and the hydrogen bonding, which does not have a methionine residue nearby, therefore does not exist danger of HSA hydrolysis by these complexes.

AB  - A new magnetic amino-functionalized polymeric sorbent based on glycidyl methacrylate was synthesized and used in the separation of chromium Cr(VI) oxyanions sorption from aqueous solutions in a static batch system. The kinetic and isothermal parameters of the sorption process were determined. The experimental data were best fitted by a pseudo-second-order model with R2 = 0.994 and χ2 = 0.004. The sorption process of Cr(VI) removal by amino-functionalized sorbent was controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, followed closely by the Sips isotherm model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups that coated the magnetic nanoparticles. The calculations showed that Cr(VI) oxyanions (Cr2O72−, CrO42− and HCrO4−) bind to both sorption sites, with diethylenetriamine centers slightly favored. The X-ray photoelectron spectroscopy (XPS) spectra demonstrate that the chromium bound to the sorbent in the form of Cr(III), indicating that the Cr(VI) can be converted on the surface of the sorbent to a less harmful form Cr(III) due to the sorbent’s chemical composition.

AB  - A spirohydantoin derivative (Figure 1) was synthesized and its crystal structure wasdetermined by single crystal X-ray diffraction and analysed by DFT calculations. Thecrystal packing is made of supramolecular nets of R64(32) rings linked together to formstacks that enclose linear channels. The intermolecular interaction energies are quantifiedfor various dimeric motifs. By including the previously reported structurally-relatedspirohydantoins [1], we created a set of compounds that enabled us to evaluate substituenteffects on both molecular and crystal structures.

AB  - Interest in Cd complexes has been growing in recent years. Cd complexes are considered a potential solution in the search for novel antibiotics that can fight antimicrobial resistance. In addition, Cd complexes draw attention to material chemistry. The main objective of this work was to prepare the first Cd(II) complexes with anionic forms of pyridine-based thiazolyl hydrazone (THs) ligands HLS2 [(E)-4-(4-methoxyphenyl)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)thiazole] and HLS3 [(E)-2-(2-[pyridine-2-ylmethylene]hydrazinyl)-4-(p-tolyl)thiazole] and perform their structural and spectroscopic characterization, as well as stability in solution and upon heating. Studies related to their biological activities and possible electrochromic applications are also being conducted. Complexes [Cd(HLS2)2] (1) and [Cd(HLS3)2] (2) have been characterized by a single-crystal X-ray diffraction and computational analysis of intermolecular interactions responsible for their solid-state structures was performed. Thermal stability of 1 and 2 in the solid-state was analyzed by TGA/MS, where as their solution stability was determined by the spectrophotometric titration method. Electrochemical and in situ UV–Vis spectroelectrochemical analyses of 1 and 2 were carried out to determine redox mechanisms and the influence of the substituents and electrolytes on their redox responses. The antioxidant capacity of both complexes was tested in antioxidant assays, while their antimicrobial activity was tested against five Gram-positive and four Gram-negative bacteria, as well as against three fungi. The obtained results indicate their potent antioxidant capacity. The antimicrobial activity of investigated compounds on almost all tested bacterial strains was stronger than that of the standard antibiotic erythromycin. The results of docking studies indicate that the minor groove DNA is the possible biological target of 1 and 2.

AB  - The mechanism of action of most approved drugs in use today is based on their binding to specific proteins or DNA. One
of the achievements of this research is a new perspective for recognition of binding modes to DNA by monitoring of
changes in measured and stoichiometric values of absorbance at 260 nm. UV–Vis and IR spectroscopy, gel electrophoresis
and docking study were used for investigation of binding properties of three dinuclear platinum(II) complexes containing
different pyridine-based bridging ligands, [{Pt(en)Cl}2(μ-4,4’-bipy)]Cl2・2H2O (Pt1), [{Pt(en)Cl}2(μ-bpa)]Cl2・4H2O (Pt2)

1,2-bis(4-pyridyl)ethene, respectively). In contrast to the system with well-known intercalated ligand (EtBr), covalently bound
ligand (cis-Pt) and with minor groove binder (Hoechst 33258), which do not have significant differences in measured and
stoichiometric values, the most pronounced deviations are recorded for two dinuclear platinum(II) complexes (Pt1 and Pt2),
as a consequence of complex binding to the phosphate backbone and bending of DNA helix. The hydrolysis of complexes
and changes in DNA conformation were also analysed as phenomena that may have an impact on the changes in absorbance.

AB  - Improving the affinity and selectivity of polymeric materials for sorbing ionic species, particularly
heavy metals that pose a high environmental risk, is crucial from an environmental standpoint.
Research on the mechanism of sorption can aid in selecting the optimal sorbent for a given
application. Sorption occurs as a result of various interactions. Sorption includes diffusion of ions
through solution (typically the quickest), diffusion of ions through the boundary layer surrounding
the sorbent surface, diffusion through the porous structure of the sorbent (intra-particle diffusion),
and binding to active sites on sorbent surfaces. Kinetic and equilibrium models explain the sorption
mechanism but not the nature of interactions, which is essential for predicting the selectivity and
efficiency of the sorbent based on particular ionic species. As a result, we were compelled to
approach the molecular level. Active sites on the surface of the magnetic aminofunctionalized
polymer, which are amino functional groups, are used to bind ions to the magnetic nanocomposite.
The sorption process can be viewed as the sum of ion-ligand unit interactions. Unit complex
formation and stability can be studied with statistical analysis and quantum chemical calculations.
The Cambridge database (CSD) improves the crystal structure of complex ion-ligand. Based on
binding energy, DFT (Density Functional Theory) predicts the stability of complex molecules (unit
ion-ligand interactions). To ensure an accurate calculation, it is essential to include all system
parameters, including sorbent structure, ligand properties, ligand charge under specific conditions,
ion forms and charges, and solvatation effects. In the early stages of research, defining the system's model lets researchers make theoretical predictions about the magnetic aminofunctionalized polymer sorbent's affinity and selectivity for certain ionic species.

AB  - Two spirohydantoin derivatives, 3-(4-chlorobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (1) and 3-(4-bromobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (2), were synthesized and analyzed by single crystal X-ray diffraction, DFT and QTAIM calculations. Simple substitution of the benzoyl unit gave rise to different crystal structures. In 1, a parallel stack along the b-axis with alternating perpendicular separation is formed, while in 2 the R46(32) nets are joined together to form stacks which enclose linear channels. Hierarchical development of these crystal structures was analyzed through dimeric motifs associated with the presence of intermolecular interactions. By including the previously reported structurally-related spirohydantoin derivatives, we created a set of structures which enabled us to evaluate substituent effects on their conformational preferences, i.e., widening of the dihedral angle between the hydantoin and substituted benzoyl unit when going from F to Br. A conformational search revealed that the value of the torsion angle N3-C11-C12-C13 can be regarded as a compromise between the extended conjugation between the carbonyl and phenyl group and intramolecular C-H⋯O interaction between these two groups. This intramolecular effect is more pronounced on the torsion angle C2-N3-C11-C12, which defines the relative orientation between the hydantoin ring and the carbonyl bridge. The present work may provide a basis for design of new cyclohexane-5-spirohydantoins with potential for pharmaceutical applications both at the molecular and supramolecular level.

The most active analyzed platinum complexes induced time-dependent growth inhibition of A375, HeLa, PANC-1, and MRC-5 cells. The best efficiency was achieved on HeLa and PANC-1 cells for Pt1, Pt2, and Pt3 at the highest concentration, while Pt1 was significantly more potent than cisplatin at a lower concentration. Additionally, a lower effect on normal cells was observed compared to cisplatin, which may indicate potentially fewer side effects of these complexes. Selected complexes induce reactive oxygen species and apoptosis on tumor cell lines. The most potent reversible acetylcholinesterase (AChE) inhibitors were Pt2, Pt4, and Pt5. Pt1 showed similar inhibitory potential toward AChE as cisplatin, but a different type of inhibition, which could contribute to lower neurotoxicity. Docking studies revealed that Pt2 and Pt4 were bound to the active gorge above the catalytic triad. In contrast, the other complexes were bound to the edge of the active gorge without impeding the approach to the catalytic triad. According to this, Pt1 represents a promising compound with potent anticancer properties, high selectivity, and low neurotoxicity.

AB  - Coordination effects have been considered through the most common interactions in the crystal structures of fluoro compounds (C–H/F and F/F interactions). The supramolecular profile of these effects is based on quantum-chemical calculations for the assessment of the interaction strength and electrostatic potential maps, which provide a qualitative insight into the examined effect. Coordination of aliphatic fluorides leads to an increase of the negative potential of the F atoms, and, hence, an increase in the hydrogen-bonding acceptor ability (strengthening of C–H/F interactions) and a weakening of the F/F interactions, due to an increase in repulsive interactions between the F atoms. There is no significant change in the potential of the F atoms due to coordination of C6-aromatic fluorides, as in the case of aliphatic ones. This results in slight changes in the strengths of the C–H/F and F/F interactions (coupled with parallel interaction at large offsets, PILO), in a noticeable enhancement of stacking interactions, as well as in a significant enhancement of interactions involving the π-system (F/π and C–H/π interactions). It has also been shown that a decrease in the charge of the metal ions leads to a decrease in the negative potential of the F atom and also that the nature of the metal ion has a significant influence on the value of the potential of the F atoms.

AB  - A racemic spirohydantoin derivative bearing a tetralin and 4-methoxybenzyl group was synthesized
and its crystal structure was determined. The hierarchical development of the crystal packing was
discussed through cooperativity of various homo and heterohiral dimeric motifs associated with the
presence of different intermolecular interactions. A hallmark structural feature of the investigated
compound was alternation of double layers. A larger number of the contact fragments in the
environment of the tetralin unit results from its larger contact surface, while the 4-methoxybenzyl
unit provides a slightly greater contribution to the overall stabilization. Regarding the
pharmacological potential of the investigated compound, we performed a docking study on the
dopamine D3 receptor and IRAK 4 (Interleukin-1 Receptor-Associated Kinase 4) enzyme. The total
number of amino acid, which interact with the 4-methoxybenzyl unit, was slightly larger than the
number of amino acids in the neighborhood of the tetralin unit as a result of its greater flexibility. It
made the 4-methoxybenzyl unit more adaptable for interactions with the biological targets.

AB  - The supramolecular approach is based on statistical analysis of data from crystal structures extracted
from the Cambridge Structural Database (CSD), quantum-chemical calculations for assess the
strength of typical interactions, and docking study for determination of the binding of S/Se
compounds to selected biomolecules. The statistical analysis has shown that S and Se atoms, in
fragments that corresponds to the side chains of cysteine (Cys), methionine (Met) selenocysteine
(Sec) and selenomethionine (Mse), display a similar tendency towards specific types of interaction.
The most numerous are structures with C-H/Se and C-H/S interactions (∼80%). The structures with
Se/Se and S/S interactions are notably less numerous (∼5%), although the C-H/Se and C-H/S
interactions (∼−0.8 kcal/mol) are weaker than the most stable parallel Se/Se and S/S interactions
(∼−3.3 kcal/mol) and electrostatic interactions of σ/π type (∼−2.6 kcal/mol). The significant
difference in numerosity can be explained by the abundance of C-H groups in analyzed crystal
structures. Docking studies revealed that S and Se rarely participate in interactions with the amino
acid residues of target enzymes, but the differences in the number and positions of their binding
sites between Se and S compounds are more pronounced if the substituents of S/Se atom are polar
and if there are more Se/S atoms in the ligand.

selenometionina (Mse), pokazuju sličnu tendenciju ka određenim vrstama interakcija. Najbrojnije su

manje zastupljene u kristalnim strukturama (∼5%), iako su C-H/Se i C-H/S interakcije (∼ -0,8 kcal/mol) slabije od najstabilnijih Se/Se i S/S interakcija sa paralelnih orientacijom (∼ -3,3 kcal/mol) i njihovih elektrostatičkih interakcija σ/π tipa (∼ -2,6 kcal/mol). Značajna razlika u brojnosti može se objasniti obiljem C-H grupa u analiziranim kristalnim strukturama. Doking studija je pokazala da S i Se atomi retko uključeni u interakcijama sa amino-kiselinskim ostacima ciljanih enzima, ali su razlike u broju i položajima vezivnih mesta izraženije ako su supstituenti vezani za S/Se polarni, ali i ako ligand poseduje više od jednog Se ili S atoma.

AB  - Kristalografska i kvantnohemijska studija, koja je usmerena na proučavanje efekata fluorovanja benzoil-grupe vezane za cikloheksan-5-spirohidantoin, pokazala je da aromatični prsten ima najveći afinitet prema cikloheksanskom prstenu (nepolarnim grupama), sa kojim gradi C–H∙∙∙π i 
paralelne interakcije sa velikim pomakom. Uvođenje atoma fluora na aromatični prsten dovodi do 
povećanog afiniteta, usled stvaranja dodatnih C–H∙∙∙F interakcija. Dodatno, ova studija je 
proširena na hlorovane i bromovane derivate. Analizom kristalnog pakovanja četiri derivata spirohidantoina (slika) pokazano je da orijentacija aromatičnog prstena, koja je preko rotabilne 
C(aromatični)–C(karbonilni) veze odvojena od rigidnog spirohidantoinskog jezgra, određuje
trodimenzionalnu supramolekulsku arhitekturu. Energijski profil rotabilne veze (slika) jako zavisi 
od vrste halogenog atoma vezanog za aromatični prsten (X). Najvišu barijeru (najmanju rotacionu 
slobodu) ima aromatični prsten sa Br atomom (oko 36 kcal/mol), dok najnižu barijeru imaju 
prstenovi sa vezanim Cl ili F atomom (oko 7 kcal/mol). Izmerene vrednosti torzionog ugla T 
(slika) u kristalnim stukturama, koji definiše rotabilnost ove veze, odgovaraju minimumima energije na energijskim profilima. Kod ovih orijentacija aromatični prstenovi istovremeno grade C–
H...π interakcije sa hidantoinskim prstenom i C–H...O interakciju sa karbonilnom grupom koja 
premošćuje dva prstena. Na osnovu ovih rezultata može se zaključiti da su orijentacije aromatičnog prstena određene unutarmolekulskim interakcijama, a ne međumolekulskim interakcijama, kao i da su konformacione razlike uzrok razlika u kristalnom pakovanju ovih jedinjenja.
AB  - The crystallographic and quantum chemical study, focused on the effects of fluorination of the 
benzoyl group bound to the spirohydantoin moiety, showed that the aromatic ring has the highest 
affinity towards the cyclohexene ring (nonpolar groups), thus forming C–H∙∙∙π and parallel interactions at large offset. Introduction of a fluorine atom into the aromatic ring leads to higher affinity, due to formation of additional C–H∙∙∙F interactions. Subsequently, the present study has been extended to chlorinated and brominated derivatives. An analysis of the crystal packaging of four spirohydantoin derivatives has shown that the orientation of the aromatic ring, bound to the rigid spirohydantoin moiety by the rotatable C(aromatic)–C(carbonyl) bond, determines the three-dimensional supramolecular architecture. The energy profile of the rotatable bond (Figure) strongly depends on the halogen atom bound to the aromatic ring (X). The highest barrier (the lowest rotational freedom) has been found for the aromatic ring with the Br atom (36 kcal/mol), while the rings with the Cl or F atom have the lowest barrier (7 kcal/mol). The measured values of the torsion angle T in the crystal structures which defines the rotability of the mentioned bond, correspond to the energy minima on the energy profiles. In these orientations, the aromatic ring simultaneously forms C–H...π interactions with the hydantoin ring and C–H...O interaction with the carbonyl spacer group. Based on these results, one can conclude that the orientation of the aromatic ring is defined by intramolecular interactions, not by intermolecular interactions, as well as that the conformational differences further cause differences in the crystal packaging of these compounds.
