AB  - Serotonin receptors modulate numerous behavioral and neuropsychological processes.
Therefore, they are the target for the action of many drugs, such as antipsychotics, antidepressants,
antiemetics, migraine remedies, and many others. The 5-HT1A receptors have been involved in the
pathogenesis and treatment of anxiety and depression and represent a promising target for new
drugs with reduced extrapyramidal side effects. In most antidepressants, a piperazine-based structural
motif can be identified as a common moiety. Here we describe the synthesis, pharmacological,
and in silico characterization of a novel arylpiperazines series with excellent 5-HT1A affinity. The
final compounds, 4a, 8a, and 8b, were selected according to predictions of in silico pharmacokinetics,
docking analysis, and molecular dynamics in conjunction with physical properties, and metabolic
stability. The accentuated molecules could serve as a lead compound for developing 5-
HT1A drug-like molecules for depression treatment.

AB  - Adrenergic receptors are among the most studied G protein-coupled receptors. Activation or blockade of these receptors is a major therapeutic approach for the treatment of numerous disorders such as cardiac hypertrophy, congestive heart failure, hypertension, angina pectoris, cardiac arrhythmias, depression, benign prostate hyperplasia, anaphylaxis, asthma, and hyperthyroidism. Among all nine cloned adrenoceptor subtypes and the subsequent development of animal models, a significant target for various neurological conditions treatment is alpha1-adrenergic receptors. 2-{[4-(2-Methoxyphenyl)piperazin-1-yl]alkyl}-1H-benzo[d]imidazoles, their 5 substituted derivatives, and structurally similar, arylpiperazine based alpha1-adrenergic receptors antagonists (trazodone, naftopidil, and urapidil) have been subjects of comparative analysis. Most of the novel compounds showed alpha1-adrenergic affinity in the range from 22 nM to 250 nM. The in silico docking and molecular dynamics simulations, binding data together with absorption, distribution, metabolism, and excretion (ADME) calculations identified the promising lead compounds. The results brought out the conclusions which allowed us to propose a rationale for the activity of these molecules and to highlight six compounds (2-5, 8, and 12) that exhibited an acceptable pharmacokinetic profile to the advanced investigation as the potential alpha1-adrenergic receptor antagonists.

AB  - Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ring and two compounds are 3-carbomethoxy derivatives of fentanyl. Among them, five are diastereomeric cis/trans couples and six novel trans diastereomers. In addition, the lipophilicity and ionization constant of fentanyl were also determined by the same method, as a reference. The physicochemical property, lipophilicity, expressed as retention indices RM0, b, and C0, as well as PC1, was determined and correlated with in silico values. Ionization constants were determined on the basis of the relationships between analyte's retention expressed as RF and mobile phase pH. Calculated structural descriptors together with the retention indices, were subjected to the principal component analysis – PCA and hierarchical cluster analysis – HCA, in order to provide basic insights into the similarities among the studied compounds. The blood – brain barrier (BBB) permeation was investigated in the function of experimentally obtained values of lipophilicity, polar surface area and molecular weight. In general, results of the present research corroborate well with previously determined antinociceptive activities of the investigated compounds, pointing out that besides the cis/trans isomerism, another set of important parameters should be taken into account when designing new derivatives of C-3 substituted fentanyl, especially lipophilicity, voluminosity and HBD/A character of the substituents. Accordingly, RP-TLC can be considered as a valuable asset in the ligand-based drug design.

AB  - The binding of a popular food supplement and well-known antioxidant, dihydro-alpha-lipoic acid (DHLA) to human serum albumin (HSA) was characterised. The binding was monitored by several spectroscopic methods together with the molecular docking approach. HSA was able to bind DHLA with moderate affinity, 1.00±0.05×104 M-1. Spectroscopic data demonstrated that the preferential binding site for DHLA on HSA is IIA (Sudlow I). Both experimental and molecular docking analysis identified electrostatic (salt bridges) and hydrogen bonds as the key interactions involved in DHLA binding to HSA. Molecular docking confirmed that the Sudlow I site could accommodate DHLA and that the ligand is bound to the protein in a specific conformation. The molecular dynamic simulation showed that the formed complex is stable. Binding of DHLA does not affect the structure of the protein, but it thermally stabilises HSA. Bound DHLA had no effect on the susceptibility of HSA to trypsin digestion. Since DHLA is a commonly used food supplement, knowledge of its pharmacokinetics and pharmacodynamic properties in an organism is very important. This study further expands it by providing a detailed analysis of its interaction with HSA, the primary drug transporter in the circulation.

AB  - A reduced form of the alpha-lipoic acid, dihydro-alpha-lipoic
acid (DHLA) is a potent, naturally occurring antioxidant that is
found in higher amounts in plants like spinach, broccoli, potatoes,
tomatoes, carrots, beets and rice. DHLA can be consumed
as a food supplement as well, at doses up to 600 mg/day. DHLA
has an inhibitory effect on coagulation as it can reduce concentrations
of some coagulation factors. This study investigated a
direct interaction between DHLA and fibrinogen, the main protein
in coagulation and hemostasis. DHLA binds fibrinogen with
a moderate straight. Calculated constant from spectrofluorimetric
titration for DHLA/fibrinogen complex was 104 M -1. Fibrinogen
stability remains the same with only marginal structural changes
in its secondary structure favouring more ordered molecular
organisation upon DHLA binding, as determined by Fourier transform
infrared spectroscopy. Coagulation assay showed that
fibrinogen with bound DHLA forms fibrin with thicker fibres, as
measured by coagulation assay and is protected from oxidation to
a certain extent. Docking analysis showed that DHLA may bind
fibrinogen in its D regions, which are directly involved in the fibrin
formation. Obtained results support beneficial effects of DHLA
on fibrinogen and consequently on coagulation process, suggesting
that DHLA supplementation may be indicated for persons with

abstract = "A reduced form of the alpha-lipoic acid, dihydro-alpha-lipoic
acid (DHLA) is a potent, naturally occurring antioxidant that is
found in higher amounts in plants like spinach, broccoli, potatoes,
tomatoes, carrots, beets and rice. DHLA can be consumed
as a food supplement as well, at doses up to 600 mg/day. DHLA
has an inhibitory effect on coagulation as it can reduce concentrations
of some coagulation factors. This study investigated a
direct interaction between DHLA and fibrinogen, the main protein
in coagulation and hemostasis. DHLA binds fibrinogen with
a moderate straight. Calculated constant from spectrofluorimetric
titration for DHLA/fibrinogen complex was 104 M -1. Fibrinogen
stability remains the same with only marginal structural changes
in its secondary structure favouring more ordered molecular
organisation upon DHLA binding, as determined by Fourier transform
infrared spectroscopy. Coagulation assay showed that
fibrinogen with bound DHLA forms fibrin with thicker fibres, as
measured by coagulation assay and is protected from oxidation to
a certain extent. Docking analysis showed that DHLA may bind
fibrinogen in its D regions, which are directly involved in the fibrin
formation. Obtained results support beneficial effects of DHLA
on fibrinogen and consequently on coagulation process, suggesting
that DHLA supplementation may be indicated for persons with
an increased risk of developing thrombotic complications, particularly
those whose fibrin is characterised by increased oxidative
modification and formation of thinner and less porous fibres.
Although further investigation is needed, our results suggest that
DHLA in complex with fibrinogen can be located at the site of

AB  - 5HT1A receptor targeting drugs have been used as the treatment for the many neuropsychiatric
disorders, such as schizophrenia and depression. As a part of ongoing research, we designed series of
new compounds that share arylpiperazine common structural motif with the 5HT1A receptor ligand
aripiprazole. Receptor-ligand interactions were determined by the molecular docking simulations,
revealing the positive impact of the phenyl substitution in the arylpiperazine part of the molecules. Nine
selected compounds were synthesized in four reaction steps in high overall yields (59-73%). In vitro
pharmacological evaluation of the synthesized compounds revealed three compounds (5b, 6b and 6c)
with high 5HT1A binding affinity, comparable with aripiprazole (Ki 12.0, 4.8, 12.8, 5.6 nM,
respectively). Compounds from b series, 5b and 6b, possess 2-methoxyphenyl substituents, while 6c
possess 2,3-dichlorophenyl substituent in the arylpiperazine part of the molecule. The pharmacological
results are therefore in accordance with the molecular docking simulations thus proving the rational
design. Compounds 5c, 6b and 6c can be considered as the candidates for further evaluation as new,
potential antidepressants.

AB  - A total of 14 novel arylpiperazines were synthesized, and pharmacologically evaluated by measuring their affinities towards the D2 dopamine receptor (D2DR) in a [3H]spiperone competition assay. All herein described compounds consist of a benzimidazole moiety connected to the N-(2-methoxyphenyl)piperazine via linkers of various lengths. Molecular docking analysis and molecular dynamics simulations were performed on D2DR-arylpiperazine complexes with an
objective to explore the receptor-ligand interactions and properties of the receptor binding site. Crystal structure of D2DR that has been published recently was used throughout this study.
The major finding is that high affinity arylpiperazines must interact with both the orthosteric binding site and the extended binding pocket of D2DR and thereforeshould contain a linker of 5 or 6 methylene groups long.

AB  - Reversed-phase thin-layer chromatography and micellar thin-layer chromatography were used in order to investigate retention behaviour and to determine lipophilicity of series of 2(methoxy)phenylpiperazine dopamine D2 ligands with different size, shape and rigidity. The retention mechanism was discussed. The lipophilicity parameters obtained in conventional reversed-phase systems expressed as RM0 and C0, as well as RM values
determined in microemulsion reversed-phase systems were correlated with in silico determined lipophilicity values. In silico pharmacokinetic properties of 2-(methoxy)phenylpiperazine dopamine D2 ligands revealed the importance of experimentally determined lipophilicity values besides the molecular weight, on the blood–brain barrier permeability process. Also, the experimentally determined lipophilicity was found as a very important factor in plasma protein binding process of 2-(methoxy)phenylpiperazine dopamine D2 ligands. Besides, the Lipinski's rule of five indicates that examined ligands satisfy the criterion of drug-like molecules. The principal component analysis was performed on the experimentally determined and calculated lipophilicity values as well on the molecular descriptors which describe the pharmacokinetic properties in order to provide basic insights into similarities among the studied ligands.

AB  - Sixteen new 1-(2-methoxyphenyl)-4-(1-phenethylpiperidin-4-yl)piperazines and 1-(2-methoxyphenyl)-4-[(1-phenethylpiperidin-4-yl)methyl]piperazines were synthesized to be used as probes for mapping the dopamine D-2 receptor (D(2)DAR) arylpiperazine binding site. All compounds were evaluated for their affinity toward D(2)DAR in an in vitro competitive displacement assay. The most active one was 1-(2-methoxyphenyl)-4-{[1-(3-nitrophenethyl)piperidin-4-yl]methyl}piperazine (25) with an affinity of K-i = 54 nM. Docking analysis was conducted on all herein described compounds, whereas molecular dynamic simulation was performed on ligand 25 to establish its mode of interaction with D(2)DAR. Two possible docking orientations are proposed; the one with a salt bridge between the piperidine moiety and Asp114 of D(2)DAR is more stable.

AB  - Contacts between aromatic rings and sulfur-containing amino acids are frequent in proteins. However, little is known about the nature of their interactions particularly if substituents are present on aromatic ring. In this paper, DFT quantum chemical calculations were used to study substituted benzenes in complex with hydrogen sulfide (H2S), methanethiol (CH3SH), and (Methylsulfanyl)methane (CH3SCH3). It was found that SH(...)a interaction is more stabilizing than the S(...)a interaction in the case of benzene, but this is changed with increasing electronegativity of the substituent on benzene ring. Although the change of energy of SH...pi and S-...pi interaction follows the conventional model of substituent effect, where S-...pi interactions are maximized and SH...pi interactions are diminished with electron-withdrawing substituent on benzene as a result of changes in the aryl it-system, it was found that it is mainly a consequence of direct electrostatic interaction between substituent and the sulfur-containing molecule. We also investigated the model system of Cys(...)Trp interaction, adjacent to a cluster of aromatic amino acids, in proteins, using explicit membrane molecular dynamics simulations results of D-3 dopamine receptor crystal structure as starting point. It was found that fluorination in aromatic cluster enhances the Cys(...)Trp interaction. The effect is maximized when transferred through the rest of aromatic system suggesting possible explanation for frequent contacts between sulfur-containing and aromatic amino acids in proteins and their effects on protein folding and stabilization.

AB  - The crystal structures of the D3 dopamine receptor and several other G-protein coupled receptors (GPCRs) were published in recent times. Those 3D structures are used by us and other scientists as a template for the homology modeling and ligand docking analysis of related GPCRs. Our main scientific interest lies in the field of pharmacologically active N-arylpiperazines that exhibit antipsychotic and/or antidepressant properties, and as such are dopaminergic and serotonergic receptor ligands. In this short review article we are presenting synthesis and biological data on the new N-arylpipereazine as well our results on molecular modeling of the interactions of those N-arylpiperazines with the model of D2 dopamine receptors. To obtain that model the crystal structure of the D3 dopamine receptor was used. Our results show that the N-arylpiperazines binding site consists of two pockets: one is the orthosteric binding site where the N-arylpiperazine part of the ligand is docked and the second is a non-canonical accessory binding site for N-arylpipereazine that is formed by a second extracellular loop (ecl2) of the receptor. Until now, the structure of this receptor region was unresolved in crystal structure analyses of the D3 dopamine receptor. To get a more complete picture of the ligand - receptor interaction, DFT quantum mechanical calculations on N-arylpiperazine were performed and the obtained models were used to examine those interactions.

abstract = "The crystal structures of the D3 dopamine receptor and several other G-protein coupled receptors (GPCRs) were published in recent times. Those 3D structures are used by us and other scientists as a template for the homology modeling and ligand docking analysis of related GPCRs. Our main scientific interest lies in the field of pharmacologically active N-arylpiperazines that exhibit antipsychotic and/or antidepressant properties, and as such are dopaminergic and serotonergic receptor ligands. In this short review article we are presenting synthesis and biological data on the new N-arylpipereazine as well our results on molecular modeling of the interactions of those N-arylpiperazines with the model of D2 dopamine receptors. To obtain that model the crystal structure of the D3 dopamine receptor was used. Our results show that the N-arylpiperazines binding site consists of two pockets: one is the orthosteric binding site where the N-arylpiperazine part of the ligand is docked and the second is a non-canonical accessory binding site for N-arylpipereazine that is formed by a second extracellular loop (ecl2) of the receptor. Until now, the structure of this receptor region was unresolved in crystal structure analyses of the D3 dopamine receptor. To get a more complete picture of the ligand - receptor interaction, DFT quantum mechanical calculations on N-arylpiperazine were performed and the obtained models were used to examine those interactions.",

AB  - Research on dopamine (DA) and its receptors, and in particular the D2 receptor subclass, has been an intriguing and fast developing scientific field in the past 35 years. Methods of medicinal chemistry, molecular and structural biology as well as computational chemistry were used in the studies of DA receptors (DRs). Early attempts to describe DRs were based on a small amount of experimental data available and produced crude models at best. Once crystal structures of bacteriorhodopsin, rhodopsine, various G-protein coupled receptors, and finally D3 DR receptor became available, better and more detailed D2 DR receptor models emerged. These models gave us an insight into the mechanism of ligand-receptor interactions, and paved the way for the synthesis of new dopaminergic compounds, both agonists and antagonists and possible drugs for the treatment of different imbalances of the dopaminergic system. This review covers the key discoveries on the path to the creation of the D2 DR receptor model.

AB  - In this paper, we report the molecular modeling of the 5HT(2A) receptor and the molecular docking of arylpiperazine-like ligands. The focus of the research was on explaining the effects the ligand structure has on the binding properties of the 5HT(2A) receptor and on the key interactions between the ligands and the receptor-binding site. To see what the receptor-ligand interactions were, various substituents were introduced in one part of the ligand, keeping the rest unchanged. In this way, using a docking analysis on the proposed 5HT(2A) receptor model, we identified key receptor-ligand interactions and determined their properties. Those properties were correlated with experimentally determined binding affinities in order to determine the structure to activity relationship of the examined compounds.

AB  - The dopaminergic receptor system has been the focus for the development of new pharmacotherapeutic agents targeting a number of central nervous system related disorders, such as drug addiction, schizophrenia, depression, and Parkinson's disease, to name just a few. To date, the crystal structure for the human D2 receptor is not known, despite its vital function and importance as a therapeutic target. Herein, a recent advancement in the determination of key receptor ligand interactions for the available arylpiperazine-like ligands, using a D2 receptor model based on the crystal structure of the D3 receptor is presented. To determine key interactions responsible for high dopaminergic activity, computer-docking analysis was used together with experimental data. A total of 4 dopaminergic ligands showing moderate to high affinity were tested and the obtained results rationalized using ligand structures docked into the proposed D2 receptor model.

AB  - Interest in structure-based G-protein-coupled receptor (GPCR) ligand discovery is huge, given that almost 30 % of all approved drugs belong to this category of active compounds. The GPCR family includes the dopamine receptor subtype D2 (D2DR), but unfortunately-as is true of most GPCRs-no experimental structures are available for these receptors. In this publication, we present the molecular model of D2DR based on the previously published crystal structure of the dopamine D3 receptor (D3DR). A molecular modeling study using homology modeling and docking simulation provided a rational explanation for the behavior of the arylpiperazine ligand. The observed binding modes and receptor-ligand interactions provided us with fresh clues about how to optimize selectivity for D2DR receptors.

AB  - The ratio of affinities toward the dopamine D-2 and the 5-hydroxytryptamine 5-HT1A receptors is one of the important parameters that determine the efficiency of antipsychotic drugs. Here, we present the synthesis of ortho-, meta-, and para-N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides and their structure-activity relationship studies on dopamine D-2 and 5-hydroxytryptamine 5-HT1A receptors. It was shown that the biological activity of the described ligands strongly depends on their topology as well as on the nature of the heteroaryl group in the head of the molecules. Docking simulations together with conformational analysis revealed a rational explanation for the ligands' behavior. The molecular model of receptor-ligand interactions described herein provided us with a tool for the rational design of new compounds with a favorable D-2/5-HT1A profile.

AB  - Molecular modelling studies were undertaken in order to identify key interactions of selected ligands with alpha(1A) adrenergic receptor, responsible for their binding and presumably receptor activation. The previously made model of alpha(1A) adrenergic receptor was optimized by molecular dynamics and different arylpiperazine ligands were docked. The results show a high correlation to the experimentally determined binding affinities. Ligand orientations and its interactions with specific amino acid residues in the binding site explain trends in its structure-activity relationship. The key interactions for those trends are mainly aromatic, which are suggested by the calculation of their ESP surfaces.
