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  - Visible light promoted photoredox catalyzed formation of α-amino radicals from cyclic tertiary amine compounds and their subsequent addition to Michael acceptors performed in flow conditions allowed access to a wide range of functionalized N-aryl-substituted tetrahydroisoquinolines (THIQs) and N-aryl-substituted tetrahydro-β-carbolines (THBCs). Visible light in conjunction with Ru(bpy)3Cl2 photocatalyst allowed the formation and high reactivities of α-amino radicals in flow conditions at room temperature. These reactions gave valuable products with high efficiencies; some previously unavailable reaction 
pathways photo or thermal reaction conditions; i.e. direct synthesis of 1-substituted (THBCs) via α-amino radical path were successfully realized in flow. The use of custom-made FEP tube microreactor proved to be the key to succesfull α-amino-radical formation and overall reaction performance in flow. Three types of light transparent custom-made microfluidic devices were tested, among them glass/silicon and FEP type reactor showed very good results in the conversion of tested compounds. Plausible reaction mechanism is proposed in accordance with known principles of photo activation of tertiary amines.

AB  - Application of microfluidic devices in the visible light promoted cross-dehydrogenative coupling reactions (CDC) of N-aryl-tetrahydroisoquinolines (THIQs), priviledged, biologically active structures, using Ru(bpy)3Cl2 complexes as photosenzitizers proved as a very efficient strategy for C-1 functionalization of THIQs including Mannich reaction, Strecker reaction, and alkynylation reaction setups. The use of a gas porous PDMS microreactor proved to be crucial regarding the C–H oxidation step. Based on our results the utilization of microreactors in CDC coupling reactions has great perspective and has high importance in the functionalization of biologically active structures such as THIQs.
AB  - Primena mikrofluidnih uređaja u direktnoj funkcionalizaciji biološki aktivnih N-ariltetrahidroizohinolina, u prisustvu fotokatalizatora Ru(bpy)3Cl2, ukazuje na superiornost ove eksperimentalne tehnike u odnosu na konvencionalne reaktore. Mikrofluidni uređaji su primenjeni za ispitivanje Manihove reakcije, Štrekerove reakcije i reakcije alkinilovanja. Kako je za reoksidaciju fotokatalizatora neophodan kiseonik, mikroreaktor od PDMS-a koji je porozan za gasove omogućio je najefikasniju oksidaciju u poređenju sa drugim ispitivanim mikroreaktorima.

AB  - In recent years, the application of microfluidic devices demonstrated significant promise as a novel method in organic chemistry. One of the research fields in which microfluidics have shown a great potential is visible light photoredox catalysis. The implementation of microreactors offers considerable advantages over the batch reactor as follows: a more predictable reaction scale-up, ecreased safety hazards, preserves atom economy, improved reproducibility and yields, and decreased energy consumption. The high surface-area-to-volume ratios provide more efficient irradiation of a reaction mixture, reduction of irradiation times, and hence prevention of undesired side reactions. As a result, enhanced selectivity, product purity, and lower catalyst loading are achieved, which leads to overall more sustainable and greener processes. Even though significant rogress has been achieved, greener alternatives to many common industrial processes still remain elusive, especially in the fine chemicals industry. To perform rocesses greener and cheaper, catalysis is a key tool to reduce energy consumption and develop more atom-economical transformations. To show the potential use of 
microdevices in organic synthesis, we have applied microfluidic chemistry in mutual photoredox and organocatalytic synthesis of the functionalized tetrahydroisoquinoline, a biologically active compound with interesting pharmaceutical properties. The results obtained in microreactor devices were compared with those obtained in batch reactions and it was demonstrated that microreactors can achieve superb yields and decreased waste generation. Thus, microflow photochemistry unambiguously has demonstrated its superiority over conventional reactor systems and its potential as green technology in synthesis processes.

AB  - Xanthine oxidase (XO) is a versatile metalloflavoprotein enzyme that is best known for its rate-limiting role in the purine degradation pathway. Therapeutic inhibition of XO is based on its role in a variety of diseases that is attributed either to the hyperproduction of uric acid, or the hyperproduction of reactive oxygen species. Herein, we report the assessment of XO inhibitory properties of 24 1,2,3,4-tetrahydroisoquinoline derivatives, among which compound 
16 exhibited IC50 value of 135.72 ± 2.71 µM. The interaction of compound 16 with XO enzyme was simulated using the Site Finder module, molecular docking and molecular dynamics. Molecular modeling suggests that interactions with Met 1038, Gln 1040, Thr 1077, Gln 1194 and Val 1259 are an important factor for inhibitor affinity toward the XO enzyme. Our proposed binding model might be beneficial for the discovery of new active 1,2,3,4-tetrahydroisoquinoline-based inhibitors of XO enzyme.
AB  - Ksantin oksidaza (XO) je metaloflavoproteinski enzim, koji je najpoznatiji po svojoj ulozi ograničavanja brzine razgradnje purinskih nukleotida. Terapijska inhibicija XO zasniva se na njenoj ulozi u brojnim bolestima, koje su povezane bilo sa hiperprodukcijom mokraćne kiseline ili hiperprodukcijom reaktivnih kiseoničnih vrsta. U ovom radu izvršeno je ispitivanje sposobnosti inhibicije XO 24 derivata 1,2,3,4-tetrahidroizohinolina, od kojih je jedinjenje 16 pokazalo IC50 vrednost od 135,72 µM ± 2,71 µM. Interakcija jedinjenja 16 sa XO enzimom simulirana je korišćenjem Site Finder modula molekularnog dokinga i molekularne dinamike. Molekulsko modelovanje ukazuje na to da su interakcije sa Met 1038, Gln 1040, Thr 1077, Gln 1194 i Val 1259 važan faktor postojanja afiniteta inhibitora prema XO enzimu. Naš predloženi model vezivanja mogao bi biti od značaja za razvoj novih aktivnih inhibitora XO zasnovanih na 1,2,3,4-tetrahidroizohinolinskom heterociklusu.

U ovom radu izvršeno je ispitivanje sposobnosti inhibicije XO 24 derivata 1,2,3,4-tetrahidroizohinolina, od kojih je jedinjenje 16 pokazalo IC50 vrednost od 135,72 µM ± 2,71 µM. Interakcija jedinjenja 16 sa XO enzimom simulirana je korišćenjem Site Finder modula molekularnog dokinga i molekularne dinamike. Molekulsko modelovanje ukazuje na to da su interakcije sa Met 1038, Gln 1040, Thr 1077, Gln 1194 i Val 1259 važan faktor postojanja afiniteta inhibitora prema XO enzimu. Naš predloženi model vezivanja mogao bi biti od značaja za razvoj novih aktivnih inhibitora XO zasnovanih na 1,2,3,4-tetrahidroizohinolinskom heterociklusu.",

AB  - Deoxyribonuclease I (DNase I) inhibitory properties of two 1-(pyrrolidin-2-yl)propan-2-one derivatives were examined in vitro. Determined IC50 values of 1-[1-(4-methoxyphenyl)pyrrolidin-2-yl]propan-2-one (1) (192.13±16.95 μM) and 1-[1-(3,4,5-trimethoxyphenyl)pyrrolidin-2-yl]propan-2-one (2) (132.62±9.92 μM) exceed IC50 value of crystal violet, used as a positive control, 1.89- and 2.73-times, respectively. Compounds are predicted to be nontoxic and to have favorable pharmacokinetic profiles, with high gastrointestinal absorption and blood-brain barrier permeability. Molecular docking and molecular dynamics simulations suggest that interactions with Glu 39, Glu 78, Arg 111, Pro 137, Asp 251 and His 252 are an important factor for inhibitors affinity toward the DNase I. Determined inhibitory properties along with predicted ADMET profiles and observed interactions would be beneficial for the discovery of new active 1-(pyrrolidin-2-yl)propan-2-one-based inhibitors of DNase I.

AB  - In this study, seven new 4-oxothiazolidine derivatives were synthesized and assayed, along 7 known derivatives, for inhibitory properties against deoxyribonuclease I (DNase I) and xanthine oxidase (XO) in vitro. Among tested compounds, (5Z)-Ethyl-2-(2-(cyanomethylene)-4-oxothiazolidin-5-yliden)acetate (6) exhibited inhibitory activity against both enzymes (DNase I IC50 = 67.94 ± 5.99 μM; XO IC50 = 98.98 ± 13.47 μM), therefore being the first reported dual inhibitor of DNase I and XO. Observed DNase I inhibition qualifies compound 6 as the most potent small organic DNase I inhibitor reported so far. Derivatives of 2-alkyliden-4-oxothiazolidinone (1) inhibited DNase I below 200 μM, while the other tested 4-oxothiazolidine derivatives remained inactive against both enzymes. The molecular docking and molecular dynamics simulations into the binding sites of DNase I and XO enzyme allowed us to clarify the binding modes of this 4-oxothiazolidine derivative, which might aid future development of dual DNase I and XO.

abstract = "In this study, seven new 4-oxothiazolidine derivatives were synthesized and assayed, along 7 known derivatives, for inhibitory properties against deoxyribonuclease I (DNase I) and xanthine oxidase (XO) in vitro. Among tested compounds, (5Z)-Ethyl-2-(2-(cyanomethylene)-4-oxothiazolidin-5-yliden)acetate (6) exhibited inhibitory activity against both enzymes (DNase I IC50 = 67.94 ± 5.99 μM; XO IC50 = 98.98 ± 13.47 μM), therefore being the first reported dual inhibitor of DNase I and XO. Observed DNase I inhibition qualifies compound 6 as the most potent small organic DNase I inhibitor reported so far. Derivatives of 2-alkyliden-4-oxothiazolidinone (1) inhibited DNase I below 200 μM, while the other tested 4-oxothiazolidine derivatives remained inactive against both enzymes. The molecular docking and molecular dynamics simulations into the binding sites of DNase I and XO enzyme allowed us to clarify the binding modes of this 4-oxothiazolidine derivative, which might aid future development of dual DNase I and XO.",

AB  - Herein we report an assessment of 24 1,2,3,4-tetrahydroisoquinoline derivatives for potential DNase I (deoxyribonuclease I) inhibitory properties in vitro. Four of them inhibited DNase I with IC50 values below 200 μM. The most potent was 1-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)propan-2-one (2) (IC50=134.35±11.38 μM) exhibiting slightly better IC50 value compared to three other active compounds, 2-[2-(4-fluorophenyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]-1-phenylethan-1-one (15) (IC50=147.51±14.87 μM), 2-[2-(4-fluorophenyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]cyclohexan-1-one (18) (IC50=149.07±2.98 μM) and 2-[6,7-dimethoxy-2-(p-tolyl)-1,2,3,4-tetrahydroisoquinolin-1-yl]cyclohexan-1-one (22) (IC50=148.31±2.96 μM). Cytotoxicity assessment of the active DNase I inhibitors revealed a lack of toxic effects on the healthy cell lines MRC-5. Molecular docking and molecular dynamics simulations suggest that interactions with Glu 39, His 134, Asn 170, Tyr 211, Asp 251 and His 252 are an important factor for inhibitors affinity toward the DNase I. Observed interactions would be beneficial for the discovery of new active 1,2,3,4-tetrahydroisoquinoline-based inhibitors of DNase I, but might also encourage researchers to further explore and utilize potential therapeutic application of DNase I inhibitors, based on a versatile role of DNase I during apoptotic cell death.

AB  - Herein, we demonstrate that organic, single-electron oxidant in the presence of diarylprolinol silylether type catalyst serves as a tool for the transformation of electron-rich enamines to iminium ions. These iminium ions take part in a subsequent Michael-initiated ring-closure (MIRC) reaction with in situ present nucleophile giving rise to overall cyclopropanation reaction of saturated aldehydes. Stereodefined cyclopropanes are obtained in high yields and selectivities. This one-pot transformation represents the additional example of saturated aldehydes being used in the coupled one-pot processes. (Figure presented.).

AB  - α,β‐unsaturated aldehydes have been traditionally used in LUMO lowering asymmetric aminocatalysis (iminium catalysis), while the use of saturated aldehydes as substrates in this type of catalysis has been elusive, until recently. Herein, we demonstrate that organic, single‐electron oxidants in the presence of diarylprolinol silylether type catalysts serve as effective tools for the transformation of electron rich enamines to iminium ions which partake in a subsequent Diels‐Alder reaction. This enantioselective one‐pot transformation represents the first example of saturated aldehydes being used in domino Diels‐Alder reaction processes and demonstrates the power of this protocol for construction of stereo‐defined chiral compounds and building blocks.

AB  - Eight new benzocyclobutane-2,5-diones (1a–1h) were synthesized, and their inhibitory properties
against bovine pancreatic DNase I were examined in vitro. Methods & results: Compounds 1a–1h
were synthesized using photocycloaddition of duroquinone with various phenyl-substituted ethylenes
in the presence of 18W compact fluorescent lamp (visible light). Two compounds, 1,3,4,6-tetramethyl-7-
phenylbicyclo[4.2.0]oct-3-ene-2,5-dione (1a) and 1,3,4,6-tetramethyl-7-p-tolylbicyclo[4.2.0]oct-3-ene-2,5-
dione (1b) inhibited DNase I in a noncompetitive manner with IC50 values below 150 μM and showed to
be more potent DNase I inhibitors than crystal violet, used as a positive control. In order to analyze potential
binding sites for the studied compounds with DNase I, molecular docking study was performed.
Conclusion: The studied benzocyclobutane-2,5-diones offer a good starting point for a design of new
DNase I inhibitors.

AB  - Twelve new thiazolidinones were synthesized and, together with 41 previously
synthesized thiazolidinones, evaluated for inhibitory activity against deoxyribonuclease I (DNase I) in vitro. Ten compounds inhibited commercial bovine pancreatic DNase I with an IC50 below 200 μM and showed to be more potent DNase I inhibitors than crystal violet (IC50 = 365.90 ± 47.33 μM), used as a positive control. Moreover, three compounds were active against DNase I in rat
liver homogenate, having an IC50 below 200 μM. (3‐Methyl‐1,4‐dioxothiazolidin‐2‐ylidene)‐N‐(2‐phenylethyl)ethanamide (41) exhibited the most potent DNase I inhibition against both commercial and rat liver DNase I with IC50 values of 115.96 ± 11.70 and 151.36 ± 15.85 μM, respectively. Site Finder and molecular docking defined the thiazolidinones interactions with the most important catalytic residues of DNase I, including the H‐acceptor interaction with residues His 134 and His 252 and/or H‐donor interaction with residues Glu 39 and Asp 168. The three most active compounds against both commercial and rat liver DNase I (31, 38, and 41) exhibited favorable physico‐chemical, pharmacokinetic, and toxicological properties. These observations could be
utilized to guide the rational design and optimization of novel thiazolidinone inhibitors. Thiazolidinones as novel DNase I inhibitors could have potential therapeutic applications due to the significant involvement of DNase I in the pathophysiology of many disease conditions.

AB  - We have studied pi electron delocalization in electron- deficient alkenes and push- pull alkenes by means of natural bond orbital analysis at the B3LYP/6-311+ G(d,p) level. The study revealed that the rarely mentioned pi electron donation from an electron-accepting group (Acc) toward the C=C double bond in push-pull alkenes and electron-deficient alkenes can provide up to 10% of total pi electron stabilizing energy of a push-pull system and as much as 45% in a strongly electron-deficient tetracyanoethene. The Acc -> C= C bond pi electron donation is more intense in s-trans than in s-cis conformational arrangement, but is less dependent on Z/E isomerism in push-pull alkenes, being slightly more pronounced in Z isomers. Among different Acc substituents, CN and COO-groups contribute the largest percent of stabilizing energy and NO2 the smallest. Increase in the number of Acc groups increases percentage contribution of Acc -> C= C bond p electron delocalization to a system stabilization. A difference in pi*(C=C) orbital occupancy between isomers can be related with their chemical reactivity.

AB  - The sulfoxide functional group is common in pharmaceutically important compoundsand many sulfoxides are known to have high biological activity. Sulfur oxidation of 4-oxothiazolidine may result in more potent compounds. Although synthesis, chemicalbehavior, and biological activity of 4-oxothiazolidine S-oxides have been frequentlyinvestigated, no information concerning their diastereomeric purity or stereochemicalstructure has been given usually. Having this in mind, detailed investigation of 2-alkylidene-4-oxothiazolidine oxidation reaction and stereochemical characterization of sulfoxideproducts should be of interest for further investigations of sulfur oxidation in acyclic andcyclic sulfides having stereogenic center adjacent to sulfur atom.In accordance with the aims of this thesis, after initial screening of different oxidizingagents, a series of 5-substituted and 5-unsubstituted 2-alkylidene-4-oxothiazolidine S-oxideswere synthesized by the sulfur-oxidation of the parent sulfides with m-CPBA. The productswere obtained in good yields, 51-95%, and with moderate diastereoselectivity in case of 5-substituted derivatives (de 54-74%).The relative configuration of 5-substituted sulfoxides was determined by means ofNMR spectroscopy and DFT theoretical calculations. The structures of starting 2-alkylidene-4-oxothiazolidines and sulfoxides were optimized in the gas phase at the B3LYP/6-31G∗level. NMR chemical shifts were calculated by using the GIAO method, at the same level oftheory in the gas phase and with inclusion of solvent.On the basis of experimental and computational results it was found that thestereochemistry of the oxidation step was kinetically controlled by the reagent (m-CPBA)approach from the sterically less hindered side. Less stable anti-isomer was initially formed,but it underwent epimerization to the mixture enriched in the more stable syn-isomer, duringthe work-up process. The higher stability of syn-isomers was ascribed to the strongerhyperconjugative σC(5)−H → σ∗S−O interaction versus the weaker σ C(5)-C(5') → σ∗S−Odelocalization in their anti-counterparts and to the existence of intramolecular 1,5-C(5')H⋅⋅⋅Ohydrogen bonds.Specific reactivity of β-keto sulfoxide and vinyl sulfoxide fragments present in 2-alkylidene-4-oxothiazolidine S-oxides offer a possibility for further regioselectivefunctionalization of the studied thiazolidinone derivatives.

AB  - 4-Oxothiazolidine core, owing to the wide range of pharmacological activities exhibited by its derivatives, has been recognized as an important structural motif in biologically active compounds. A subclass constitutes 4-oxothiazolidines with an exocyclic C=C double bond at the C(2)-position. Some of these derivatives are registered as active substances for the treatment of various diseases, such as Ralitoline, an antiepileptic, Etozolin, a diuretic, and Piprozolin, a choleretic. The exocyclic C=C double bond in these compounds contains one or two electron-accepting groups at its other end, so that they also belong to the class of the so-called push-pull alkenes. In the case of the nitrogen-unsubstituted molecules, the enamino tautomeric form with the exocyclic double bond is stabilized by the extended electron delocalization arising from the push-pull effect. In the absence of push-pull effect, the imino form would dominate. Therefore, these compounds exhibit properties characteristic for both 4-oxothiazolidine ring and push-pull alkenes. They are also proved to be useful synthetic interamediates for the formation of various mono- and polyheterocycles. The importance of 4-oxothiazolidine derivatives is witnessed by several review articles, the latest published in 2012, mainly dealing with the chemistry and biological activity of various 2-imino, 2-oxo, 2-thioxo and 2-alkyl(aryl)-substituted compounds. The lack of a comprehensive review on 2-alkylidene-4-oxothiazolidines has prompted us to collect the literature covering their synthesis, structure, reactivity and biological activity. Derivatives with two exocyclic C=C double bonds are included, too.

AB  - The reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions, using Ac2O, TFAA, SOCl2 and SOBr2 as initiators, has been examined. Almost all reactions proceeded with absolute regioselectivity yielding alpha-substituted sulfides or vinyl-chloro derivatives. The mechanism for the formation of the latter products was postulated and proved experimentally.

AB  - A series of 5-unsubstituted and 5-substituted 2-alkylidene-4-oxothiazolidine-S-oxides were synthesized by the sulfur-oxidation with m-CPBA. The stereochemistry of 5-substituted sulfoxides was determined by means of NMR spectroscopy and DFT theoretical calculations. It was found that the thermodynamically less stable anti-isomer was initially formed in the course of the oxidation, but it underwent epimerization to the mixture enriched in the more stable syn-isomer, during the work-up process. The higher stability of syn-isomers is ascribed to the stronger hyperconjugative sigma(C-H)->sigma*(S-O) interaction versus the weaker sigma(C-C)->sigma*(S-O) delocalization in their anti-counterparts and to the existence of intramolecular 1,5-CH center dot center dot center dot C hydrogen bonds.

AB  - The a-C position in 4-oxo thiazolidinones functions as one of the three possible nucleophilic sites in these molecules. We used the inherent reactivity of alpha-C of the exocyclic double bond (a so called push pull system) to obtain bicyclic fused thiazolidinones via pi-annulation cyclization. Appropriate reaction conditions to selectively activate this position and secondary nitrogen towards N, pi-annulation were found. Furthermore, the intramolecular vinylogous iminium ion 6-exo-trig cyclization was used to access fused bicyclic precursors for the pi-annulation in order to obtain the novel tricyclic structures stereoselectively.
