A synthetic approach and molecular docking study of hybrids of quinazolin-4-ones and thiazolidin-4-ones as anticancer agents

A series of 3-(4-(2-(aryl)-4-oxothiazolidin-3-yl)phenyl-2-phenylquinazolin-4(3H)-one derivatives were synthesized in appreciable yield by using anthranilic acid as a starting material. The structures of synthesized compounds (QT1-QT10) were confirmed on the basis of various spectral techniques and analytical methods. These synthesized compounds were screened for their in vitro antitumor activity against the human breast cancer cell line (MCF-7), human hepatocellular cancer cell line (HepG2) using MTT assay method and doxorubicin as a standard drug. Compound 3-(4-(2-(3-chlorophenyl)-4-oxothiazolidin-3-yl)phenyl-2-phenylquinazolin-4(3H)-one (QT4) showed comparable cytotoxic activity against Hep-G2 cell line. Compound 3-(4-(2-(4-methoxyphenyl)-4-oxothiazolidin-3-yl)phenyl-2-phenylquinazolin-4(3H)-one (QT5) showed comparable cytotoxic activity against MCF-7 cell line while QT6, QT7, QT8 were the less cytotoxic as they showed high IC50 and away from that of doxorubicin. The remaining compounds did not show significant activity against both the cell lines. To understand the interaction of series with active binding site of receptor, docking study was performed with topoisomerase-II co-crystallized with adenylyl-imidodiphosphate complex using AutoDockVina. There was a good correlation between in vitro and in silico study. Thus, this investigation leads to the identification of newer anticancer agents.

ANALGESIC AND ANTI INFLAMMATORY ACTIVITY OF NEW SUBSTITUTED THIAZOLIDIN-4-ONE DERIVATIVES

4-thiazolidinones are among the most extensively investigated class of organic compounds. Thiazolidin-4-one has been considered as magic moiety, which is a core structure in various synthetic pharmaceuticals displaying a broad spectrum of biological activities. They are widely used as anti-inflammatory, anticonvulsant, analgesic, antimicrobial, anti-HIV, CNS depressant, carcinostatic, antihypertensive and cytotoxic. In view of the wide spectrum activities of condensed 4-thiazolidinones, itwas thought worthwhile to undertake the synthesis of heterocyclic systems in which 4-thiazolidinone nucleus is linked to another biologically active moiety. Semicarbazide/Thiosemicarbazide was reacted with benzoyl chloride to obtain N-hydrazinocarbonyl benzene-1-carboxamide/N-hydrazinocarbothioyl benzene-1 carboxamide respectively. These were then condensed with various aldehydes to yield the intermediate Schiff bases. Thiazolidin-4-ones were prepared by the reaction of Schiff bases with mercaptoacetic acid in dry benzene by refluxing for 16-18 hours. The purity of the compounds synthesized was established by TLC. The synthesized derivatives were characterized by FT-IR, (HNMR)-H-1 and Mass spectral analysis. All the derivatives synthesized were screened for their analgesic and anti inflammatory potency. The compounds 3A3, 3A5,3B2, 3B6 have shown equipotent analgesic activity when compared to standard Ibuprofen. The compounds 3A2, 3A5, 3B2, and 3B3 have been evaluated for their antiinflammatory properties at a dose of 50 mg/kg using carrageenan induced rat paw edema method. All the tested compounds exhibited significant anti-inflammatory activity in acute inflammatory models in rats. Compounds 3A2, 3A5, 3B2, and 3B3 exhibited significant reduction in edema volume when compared to standard Ibuprofen.

Synthesis, Cytotoxic Evaluation, Docking and QSAR Study of N-(4-Oxo2-(4-((5-Aryl-1,3,4-Thiadiazol-2-yl) Amino) Phenyl) Thiazolidin-3-yl) Benzamides as Antitubulin Agents

In the present study an efficient strategy for the synthesis of thiazole and thiadiazole derivatives was developed and clubbed together both of the substituted nucleus to form the analogues of combretastatin A-4 (tubulin polymerization inhibitors.). Synthesis was started by the reaction of substituted benzoic acid with thionyl chloride followed by the reaction with hydrazine, p-chloro benzaldehyde and thioglycolic acid to form substituted thiazole derivatives. On the other side hydrazides were reacted with ammonium thiocyanate and strong acid to form substituted thiadiazole compounds. Finally thiazole and thiadiazole compounds were clubbed with the help of dioxan and triethylamine. All novel derivatives (TH01-TH40) were screened for their cytotoxicity activity using MTT assay against three cancer cell lines viz. A-549 (lung carcinoma), HT-29 (colon carcinoma), HeLa (cervix carcinoma). Compounds TH08 exhibited highest activity, due to the presence of trimethoxy substitution on phenyl ring. In QSAR study these results were correlated with physicochemical parameters and the correlation of XlogP, kaapa2, Quadrupole1 with cytotoxic activity on A-549 (lung carcinoma) was found highest (r(2): 0.941; F: 99.103; Se: 0.0006). In docking study binding of active molecule (TH08) was found very well with alpha, beta tubulin (PDB: 1SA0) protein.

Synthesis and Anticancer Evaluation of Thiazacridine Derivatives Reveals New Selective Molecules to Hematopoietic Neoplastic Cells

Aim and Objective: Cancer has become one of the leading causes of morbidity and mortality worldwide. Limitations associated with existing agents increase the need to develop more effective anticancer drugs to improve the therapeutic arsenal available. The aim of this study was to synthesize and evaluate the antiproliferative effects of three new thiazacridine derivatives. Material and Methods: Using a three steps synthesis reaction, three novel thiazacridine derivatives were obtained and characterized: (Z)-5-acridin-9-ylmethylene-3-(4-methyl-benzyl)-4-thioxo-thiazo-lidin-2- one (LPSF/AC-99), (Z)-5-acridin-9-ylmethylene-3-(4-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-119)and(Z)-5-acridin-9-ylmethylene-3-(3-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-129). Toxicity and selectivity assays were performed by colorimetric assay. Then, changes in cell cycle and cell death induction mechanisms were assessed by flow cytometry. Results: All compounds exhibited cytotoxicity to Raji ( Burkitt’s lymphoma) and Jurkat (acute T cell leukemia) cells, where LPSF/AC-119 showed best IC50 values (0.6 and 1.53 mu M, respectively). LPSF/AC-129 was the only cytotoxic compound in glioblastoma cell line NG97 (IC50 = 55.77 mu M). None of the compounds were toxic to normal human cells and induced neoplastic cell death primarily by apoptosis. Conclusion: All derivatives were more cytotoxic to hematopoietic neoplastic cells when compared to solid tumor derived cells. All three compounds are promising for in vivo and combination therapy studies against cancer.

A computational study of regioselectivity in beta-lactam iminothiazolidinone formation

Density functional theory calculations were performed to explain the different regioselectivity for the formation of p-lactam iminothiazolidinones. Computational results were in agreement with experimental observations that phenyl and cyclohexyl derivatives led to the thermodynamically more stable regioisomers formed by cyclization at the nitrogen atom directly attached to the beta-lactam ring which was in contrast to the n-hexyl derivative where the regioisomer with the beta-lactam ring attached to the imino bond is more stable instead. It was demonstrated that the different regioselectivity was the consequence of larger steric effects when bulky substituents and the leaving ethoxy group were in close contact during the cyclization step.
