In our pursuit to develop new potential anticancer leads, we designed a combination of structural units of indole and substituted triazole; and a library of 1-{1-methyl-2-[4-phenyl-5-(propan-2-ylsulfanyl)-4H-1,2,4-triazol-3-yl]-1H-indol-3-yl}methanamine derivatives was synthesized and characterized. Cytotoxic evaluations of these molecules over a panel of(More)
Twenty eight 5-nitrothiazole derivatives were synthesized and evaluated for in vitro activities against Mycobacterium tuberculosis (MTB), cytotoxicity against HEK 293T. Among the compounds, 5-nitro-N-(5-nitrothiazol-2-yl)furan-2-carboxamide (20) was found to be the most active compound in vitro with MICs of 5.48 μM against log-phase culture of MTB and also(More)
A series of pyridazino[4,5-b]indole derivatives containing alkyl-, benzyl- and phenacyl-substituted 1,2,3-triazolylmethyl units was synthesized using click chemistry approach. All 30 compounds of the series were screened in vitro against four cancer cell lines, viz. breast cancer cells MDA-MB-231 and MCF 7, human primary glioblastoma U-87 and human(More)
Series of 2-chloronicotinaldehyde Knoevenagel derivatives 3a–r; (E)-α,β-unsaturated esters and ketones 5a–k were prepared and evaluated for their in vitro anti-mycobacterial activity against Mycobacterium tuberculosis H37Rv (Mtb). Compounds 3e, 5b, 5d, 5e, 5g and 5i–k were shown potent to significant activity. Compound 5j is the most potent Mtb inhibitor(More)
A new series of indole-isoxazolone hybrids bearing substituted amide, substituted [(1,2,3-triazol-4-yl)methoxy]methyl group or substituted benzylic ether at position-2 of the indole nucleus was synthesised using a facile synthetic route and the molecules were characterised using spectroscopic techniques. The molecules were screened against three human(More)
