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)
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)
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)
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)
