SYNTHESIS AND CHARACTERIZATIONOF NOVEL THIAZOLIDINONE DERIVATIVES OF C-MANNICH BASES

The present synthesis involves the introduction of C-Mannich bases on 4-thiazolidinone derivatives. Thiazolidinone derivatives (2a-e) were prepared by treating thiosemicarbazones (1a-e) with bromoethyl acetate and sodium acetate in DMF. C-Mannich bases (4a-b) were prepared by treating propargyl derivative of p-hydroxy benzaldehyde (3) with different secondary amines (piperidine/Morpholine), 40% formaldehyde and Cu (II) acetate in dioxane. These thiazolidinone derivatives and C-Mannich bases are condensed to get the final derivatives (5a-j). All the synthesized compounds were characterized by Mass, H-1 NMR and C-13 NMR spectra.

SYNTHESIS AND EVALUATION OF ANTI-PROLIFERATIVE ACTIVITY OF NOVEL THIAZOLIDINONE DERIVATIVES

A series of, 2-thioxo-4-thiazolidinone (rhodanine) and 2,4-thiazolidine-dinone derivatives were synthesized by reacting 4-thiazolidine-dione/rhodanine moieties with 2-(4-formylphenoxy)-N-substituted-phenyl-acetamide, in equimolar proportions. The authentication of synthesized compounds was done by FTIR, (HNMR)-H-1, and mass spectrophotometry. The derivatives, N-(phenyl) -2- {4-[(4-oxo-2-thioxo-1, 3-thiazolidin-5-ylidene) methyl] phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene)-methyl] phenoxy}-N-(phenyl)-acetamide, were further screened for their anticancer properties against CEM cell lines. Cell viability was determined by trypan blue dye exclusion assay and cytotoxic effect of the compounds by MTT assay. The two derivatives, N-(phenyl)-2-{4-[(4-oxo-2-thioxo-1,3-thiazolidin-5-ylidene) methyl] phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene)-methyl] phenoxy}-N-(phenyl)-acetamide were found to be anti-proliferative in nature at 75 – 100 mu M and 100 – 250 mu M concentrations, respectively. Thus, it can be established that the rhodanine derivatives, N-(phenyl) -2-{4-[(4-oxo-2-thioxo-1, 3-thiazolidin-5-ylidene) methyl]-phenoxy} acetamide and 2-{4-[(2,4-dioxo-1,3-thiazolidin-5-ylidene) methyl] phenoxy}-N-(phenyl)-acetamide have anti-proliferative property against leukemic cell lines (lymphoblastic leukemia) and can be further optimized to improve its efficacy and safety.

Discovery of Methyl (5Z)-[2-(2,4,5-Trioxopyrrolidin-3-ylidene)-4-oxo-1,3-thiazolidin-5-ylidene]acetates as Antifungal Agents against Potato Diseases

Synthesis, isomerism, and fungicidal activity against potato diseases of new (5Z)-[2-(2,4,5-trioxopyrrolidin-3-ylidene)-4-oxo-1,3-thiazolidin-5-ylidenelacetate derivatives with 1,3-thiazolidine-4-one and pyrrolidine-2,3,5-trione moieties linked by an exocyclic C=C bond were described. Their structures were clearly confirmed by spectroscopic and spectrometric data (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance, and mass spectrometry), elemental analysis, and X-ray diffraction crystallography. A bioassay for antifungal activity in vitro against Phytophthora infestans, Fusariun solani, Alternaria solani, Rhizoctonia solani, and Colletotrichum coccodes demonstrated that 2,4,5-trioxopyrrolidin-1,3-thiazolidine derivatives exhibited a relatively broad spectrum of antifungal activity. One of the compounds showed considerable activity against all of the strains; in the case of F. solani, P. infestans, and A. solani, it possesses comparable or better fungicidal efficacy than the positive control Consento. Consequently, this compound is a promising fungicidal candidate for plant protection.

Thiazol-4-one derivatives from the reaction of monosubstituted thioureas with maleimides: structures and factors determining the selectivity and tautomeric equilibrium in solution

2-(Alkyl(aryl)amino) thiazol- 4(5H)-ones can regioselectively be prepared from monoalkyl(aryl)thioureas and maleimides. In solution, the former heterocycles exist in a tautomeric equilibrium with 2-(alkyl(aryl) imino) thiazolidin-4-ones and the substituent on the exocyclic nitrogen atom governs the ratio of these tautomers. Isomers with the alkyl group in the endocyclic position can be obtained from N-methyl(ethyl) thioureas. 2D NMR spectroscopy and DFT calculations rationalize experimental results.

Development of quinoline-based hybrid as inhibitor of methionine aminopeptidase 1 fromLeishmania donovani

Methionine aminopeptidase 1 (MetAP1) is a target for drug discovery against many adversaries and a potential antileishmanial target for its role in N-terminal methionine processing. As an effort towards new inhibitor discovery against methionine aminopeptidase 1 fromLeishmania donovani(LdMetAP1), we have synthesized a series of quinoline-based hybrids, that is (Z)-5-((Z)-benzylidine)-2-(quinolin-3-ylimino)thiazolidin-4-ones (QYT-4a-i) whose in vitro screening led to the discovery of a novel inhibitor molecule (QYT-4h) againstLdMetAP1. The compound QYT-4h showed nearly 20-fold less potency for human MetAP1 and had drug-like features. Time-course kinetic assays suggested QYT-4h acting through a competitive mode by binding to the metal-activated catalytic site. Notably, QYT-4h was most potent against the physiologically relevant Mn(II) and Fe(II) supplemented forms ofLdMetAP1 and less potent against Co(II) supplemented form. Surface plasmon resonance and fluorescence spectroscopy demonstrated high affinity of QYT-4h forLdMetAP1. Through molecular modelling and docking studies, we found QYT-4h binding at theLdMetAP1 catalytic pocket occupying both the catalytic and substrate binding sites mostly with hydrogen bonding and hydrophobic interactions which provide structural basis for its promising potency. These results demonstrate the feasibility of employing small-molecule inhibitors for selective targeting ofLdMetAP1 which may find use to effectively eliminate leishmaniasis.

Novel Benzylidene Thiazolidinedione Derivatives as Partial PPAR gamma Agonists and their Antidiabetic Effects on Type 2 Diabetes

Peroxisome proliferator-activated receptor gamma (PPAR gamma) has received significant attention as a key regulator of glucose and lipid homeostasis. In this study, we synthesized and tested a library of novel 5-benzylidene-thiazolidin-2,4-dione (BTZD) derivatives bearing a substituent on nitrogen of TZD nucleus (compounds 1a-1k, 2i-10i, 3a, 6a, and 8a-10a). Three compounds (1a, 1i, and 3a) exhibited selectivity towards PPAR. and were found to be weak to moderate partial agonists. Surface Plasmon Resonance (SPR) results demonstrated binding affinity of 1a, 1i and 3a towards PPAR gamma. Furthermore, docking experiments revealed that BTZDs interact with PPAR gamma through a distinct binding mode, forming primarily hydrophobic contacts with the ligand-binding pocket (LBD) without direct H-bonding interactions to key residues in H12 that are characteristic of full agonists. In addition, 1a, 1i and 3a significantly improved hyperglycemia and hyperlipidaemia in streptozotocin-nicotinamide (STZ-NA)-induced diabetic rats at a dose of 36 mg/kg/day administered orally for 15 days. Histopathological investigations revealed that microscopic architecture of pancreatic and hepatic cells improved in BTZDs-treated diabetic rats. These findings suggested that 1a, 1i and 3a are very promising pharmacological agents by selectively targeting PPAR. for further development in the clinical treatment of type 2 diabetes mellitus.

5-Adamantan thiadiazole-based thiazolidinones as antimicrobial agents. Design, synthesis, molecular docking and evaluation

In continuation of our efforts to develop new compounds with antimicrobial properties we describe design, synthesis, molecular docking study and evaluation of antimicrobial activity of seventeen novel 2-{[5-(adamantan-1-yl)-1,3,4-thiadiazol-2-yl] imino}-5-arylidene-1,3-thiazolidin-4-ones. All compounds showed antibacterial activity against eight Gram positive and Gram negative bacterial species. Twelve out of seventeen compounds were more potent than streptomycin and all compounds exhibited higher potency than ampicillin. Compounds were also tested against three resistant bacterial strains: MRSA, P. aeruginosa and E. coll. The best antibacterial potential against ATCC and resistant strains was observed for compound 8 (2-{ [5-(adamantan-1yl)-1,3,4-thiadiazol-2-yl]-imino} 5 (4 nitrobenzylidene)-1,3thiazolidin-4-one). The most sensitive bacterium appeared to be S. typhimirium, followed by B. cereus while L. monocitogenes and M. flavus were the most resistant. Compounds were also tested for their antifungal activity against eight fungal species. All compounds exhibited antifungal activity better than the reference drugs bifonazole and ketokonazole (3-115 times). It was found that compound 8 appeared again to be the most potent. Molecular docking studies on E. toll MurB, MurA as well as C. albicans CYP 51 and dihydrofolate reductase were used for the prediction of mechanism of antibacterial and antifungal activities confirming the experimental results.

Synthesis of Novel Fluorine Compounds Substituted-4-thiazolidinones Derived from Rhodanine Drug as Highly Bioactive Probes

Aim and Objective: It is known that rhodanine drug has various biocidal activities. The aim of this work was to improve the structure of rhodanine drug via alkylation at N, S, and O- centers in addition to the introduction of fluorine atoms. The new fluorinated modified rhodanines 2-16 were evaluated as enzymatic probes for cellobiase activity produced by fungi and as CDK2 inhibitors of tumor cells. Materials and Methods: Novel fluorine substituted N-alkyl, S-alkyl and amino-rhodanines were obtained via Hydroxy methylation, Mannich reactions, chlorination and amination of 5-(4′-fluorophenylene)-2-thioxo-thiazolidin-4-one, and the enzymatic effects of cellobiase produced by fungi and /or CDK2 inhibition of tumor cells were evaluated. Results: Most of the targets were obtained in high yield and in the form of very pure crystals with characteristic colors. Only compounds 5, 8, 10, 13, and 14 exhibited a higher activity as cellobiase while compounds 2 and 5 showed a highly enzymatic effect on tumor cells. In addition, compounds 2 and 10 can be used as Olomoucine (standard referees). Conclusion: Various N, S and O-alkyl derivatives of fluorine-substituted rhodanines were prepared via a simple method and used as enzymatic probes for cellobiase activity produced by fungi and CDK2 inhibitors for tumor cells. The more bioactive compounds had rich fluorine atoms as p-fluorophenyl and p-fluorobenzoyl bearing N, S, O-alkyl rhodanine. The highly active compounds may be used as enzymatic materials for various biological transformations in the future.
