New nalidixic acid-1,3-thiazolidin-4-one hybrids: Design, synthesis and in vitro antimicrobial activity

In this paper, 14 new nalidixic acid-1,3-thiazolidin-4-one hybrid compounds (17-30) were synthesized by the cyclization reaction of corresponding N-substituted nalidixic acid hydrazones (3-16) with mercaptoacetic acid in the presence of 1,4-dioxane. The structures of the obtained compounds were confirmed by means of H-1 NMR and C-13 NMR spectroscopy. All newly synthesized hybrids were screened in vitro for antimicrobial activity. The antimicrobial activity assay indicated that compounds 17-30 showed good to moderate antimicrobial activity, especially against Gram-positive bacteria. Moreover, compound 29 inhibited growth of reference strains of Gram-negative bacteria belonging to Enterobacteriaceae family.

Hemisynthesis, crystal structure and inhibitory effect of sesquiterpenic thiosemicarbazones and thiazolidin-4-ones on the corrosion behaviour of stainless steel in 1 M H2SO4 solution

Treatment of thiosemicarbazones prepared from sesquiterpenes with ethyl 2-bromoacetate in the presence of sodium acetate afforded the corresponding thiazolidin-4-ones. The structures of all the newly synthesized compounds were established by considering spectral and single-crystal X-ray diffraction data. The title compound, ethyl 2-((Z)-2-{(Z)-[(1aR,5aR,9aS)-1,1-dichloro-1a, 5,5,7-tetramethyl-1a, 2,3,4,5,5a, 8,9-octahydro-1H-benzo[a] cyclopropa[b][7]annulen-8-ylidene]hydrazono}-4-oxothiazolidin-3-yl) acetate, C23H31Cl2N3O3S, 5, crystallizes in the orthorhombic noncentrosymmetric space group P2(1)2(1)2(1) with Z = 4. Within the molecule in the crystal structure, the cyclohexene ring has an envelope conformation and the cycloheptane ring, to which it is fused, has a boat conformation. In the crystal, molecules are linked by C-H center dot center dot center dot Cl hydrogen bonds forming chains propagating along the b-axis direction. The absolute configuration of the molecule in the crystal could be fully confirmed from anomalous dispersion effects [Flack parameter = -0.04 (2)]. Thiosemicarbazones 1 and 2 are efficient inhibitors for steel corrosion in 1 M H2SO4 solution, with a maximum efficiency of 92.28% at 10(-3) M. Furthermore, thiosemicarbazone compounds were found to be more efficient than thiazolidin-4-one derivatives. In addition, cyclic voltammetry was used to characterize the tested molecules, as well to estimate the experimental value of the energy band gap.

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.

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.
