AbstractBackground/Aim. Hepatocellular carcinoma (HCC) is the most common type of liver cancer and the fifth most common primary malignancy with worldwide increasing incidence. The current study aims to investigate the anticancer activities novel isosteviol derivatives towards human HepG2 hepatocellular cancer cells and in an animal model of Hepatocellular carcinoma. Materials and Methods. Twelve isosteviol derivatives were screened for their anti-proliferative activities against HepG2 and IC50 was calculated for all designed derivatives. The impact of the potent isosteviol derivative 10C on HepG2 cells was further studied by MTT assay, Annexin V/ PI staining, flow cytometry and western blotting. In vivo studies were performed to assess the anticancer effect of isosteviol derivative 10C on Diethyl Nitrosamine-induced liver cancer in female rats by evaluating the physiological processes. Results. isosteviol derivative 10C induced growth inhibition with IC50 of 2 µM mainly through induction of apoptosis in HepG2. Additionally, isosteviol derivative 10C induced G1 phase arrest, which was further confirmed by increased expression of cyclin dependent kinase inhibitor 1A (p21). It also increased BAX, BID and PARP-1 and while it reduced pro-CASPASE-3 expression and phosphorylation levels of AKT in HepG2 cells. Furthermore, western blotting data showed that E-cadherin, β- catenin, VEGF and COX-2 expressions were suppressed by isosteviol derivative 10C in HepG2 cells. In vivo study demonstrated that dose-dependent treatment of isosteviol derivative 10C led to significant reduction in tumor size compared to the untreated group after fourth injection with no significant effects on the major physiological processes. Conclusions. Taken together, in vitro and in vivo studies revealed that isosteviol derivative 10C induced apoptosis in HepG2 cells, blocked angiogenic signaling and it did not induce any apparent toxicity towards the treated hosts which merits further investigation at clinical level.
