Anticancer activity, toxicity and pharmacokinetic profile of an indanone derivative

Abstract: The present study describes anticancer effect of gallic acid based indanone derivative (1). Indanone 1 exhibited in vivo anticancer activity against Erhlich ascites carcinoma in Swiss albino mice by inhibiting tumor growth by 54.3% at 50mg/kg b.wt. It showed antitubulin effect by inhibiting tubulin polymerase enzyme. In cell cycle analysis, it inhibited G2/M phase and induced apoptosis. It significantly suppressed VEGF-R1, VEGF-R2 and HIF-α in human breast cancer MCF-7 cells, thus exhibiting antiangiogenic activity. In acute oral toxicity, indanone 1 was well tolerated and was found to be non-toxic up to 1000mg/kg b.wt. in Swiss albino mice. Pharmacokinetic studies in rabbits revealed rate of absorption, half life, volume of distribution with high plasma and blood clearance after i.v. administration. Indanone 1, is a safe and moderately active anticancer agent. [Copyright &y& Elsevier]
