A new series of 2-imino-4-thiazolidinone derivatives (7a-7t) has been synthesised and screened for their cytotoxicity against three cancer cell lines (B16F10, A549, PANC-1) and normal cell line (CHO). Among the compounds tested, compounds 7k, 7m, 7n showed potent cytotoxicity against B16F10 cell line with IC50 between 3.4 and 7μM. Interestingly these three(More)
A new series of fluoro 1,2,3-triazole tagged amino bis (benzothiazole) derivatives 8, 9 were prepared starting from 2-amino benzothiazole in four steps via amination, cyclization, alkylation followed by reaction with various azides under sharpless conditions through click chemistry approach. All newly synthesized compounds were screened for their(More)
A series of novel diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate embedded triazole and mannich bases were synthesized, and evaluated for their angiotensin converting enzyme (ACE) inhibitory activity. Screening of above synthesized compounds for ACE inhibition showed that triazoles functionalized compounds have better ACE inhibitory activity(More)
A series of novel triazole linked N-(pyrimidin-2yl)benzo[d]thiazol-2-amine 5a-k were synthesized and evaluated for anticancer activity against breast (MCF-7), lung (A549) and skin (A375) cancer cell lines and their cytotoxic effects were compared against normal breast epithelial cells. The effect of compounds on cell cycle of MCF-7 breast cancer cell line(More)
A series of novel 2-(1H-indol-3-yl)-N-(3, 4-diphenylthiazol-2(3H)-ylidene) ethanamine derivatives (5a-o) were synthesized by cyclization of corresponding 1-(2-(1H-indol-3-yl) ethyl)-3-phenylthiourea 3 with 2-bromoacetophenone. All synthesized compounds were evaluated for in vitro antibacterial activity using Gram-positive bacteria and Gram-negative(More)
