ABSTRACT
A new series of 1-((9-chloro-2,3-dimethyl-6,7-dihydro-5H-benzo[7]annulen-8-yl)methoxy)-3-(4-phenylpiperzin-1-yl) propan-2-ols (6a-k) have been designed, synthesized and their structures were established by spectroscopic data (FT-IR, 1H NMR, 13C NMR, HRMS) and further confirmed by X-ray analysis. The newly synthesized compounds 6a-k were evaluated for their in vitro anti-proliferative activity against four cancer cell lines such as HeLa (cervical), MDA-MB-231 (breast), A549 (lung) and MIAPACA (pancreatic). Among the compounds tested, the compound 6e displayed most potent activity against four cancer cell lines with GI50 values ranging from 0.010 to 0.097µM. The structure and anti-proliferative activity relationship was further supported by in silico molecular docking study of the active compounds against Colchicine binding site of ß-tubulin.

A series of benzosuberone bearing 1,2,3-triazoles were rationally designed and alkyl/aryl groups appended on 1,2,3-triazole derivatives 5a-o were synthesized using click chemistry and evaluated for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC27294). Compounds 5h (MIC: 3.125µg/mL) and 5l, 5m, 5o (MIC: 6.25µg/mL) exhibited promising hits. This is the first Letter on the synthesis and in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv of benzosuberone alkyl/aryl groups appended on 1,2,3-triazole derivatives.
