Abstract
New pyridine-O-glycosides and their acyclic nucleoside analogues were prepared by heterocyclization and glycosylation. The anticancer activity against HCT-116, HepG2 and MCF-7 human cancer cells and BJ-1 cell revealed that the galacto- and xylopyranosyl glycosides possessing 4-bromophenyl have superior cytotoxic activities against HepG2 cell while glycosides 7-9 resulted in superior cytotoxic activities regarding MCF-7 breast cell. In case of HCT-116 colorectal carcinoma cells, two products and the derived glycosides and acyclic analogues showed potent activities. The most potent compounds were investigated for their possible binding affinities to the active site of CDK2 enzyme via in silico molecular docking simulation in addition to computational studies. The results support the antiproliferative effect and elucidate the interactions of 3a and 8 with catalytic sites.
