Abstract

Hepatocellular carcinoma is one of the most common primary hepatic malignancy. Herein, a series of semisynthesized derivatives (2-30) of the natural product (+)-sclerotiorin (1) was prepared and evaluated the cytotoxic activities against six Cancer cell lines. Among them, 3 and 5 were the most effective compounds against human hepatocellular carcinoma Bel-7402 cell line with IC50 values of 1.45 and 1.15 μM, respectively. Molecular mechanism study showed that 5 disrupted the mitochondrial membrane potential and induced Apoptosis in a caspase-dependent manner. In addition, 5 affected Akt and ERK signaling pathways and induced Akt and ERK proteins degradation through ubiquitin-proteasome system. Furthermore, 5 displayed significant in vivo Anticancer effects in the xenograft models with decreasing the tumor mass by 52.5%. The safety evaluation was confirmed by acute toxicity subchronic toxicity tests, paraffin sections of mice organ and blood routine examination. Taken together, 5 can be developed as a potential therapeutic agent for hepatocellular carcinoma.
