AB The C-2 arylidene analog (compound 3) of pentacyclic triterpenoid Lantadene A (compound 1) was synthesized and evaluated by the National Cancer Institute, USA, for in vitro cytotoxicity against a panel of melanoma cancer cell lines: LOX IMVI, MALME-3M, M14, MDA-MB-435, SK-MEL-2, SK-MEL-28, SK-MEL-5, UACC-257 UACC-62 and B16F10. Compound 3 showed enhanced cytotoxicity compared with compound 1 and the standard drug cisplatin. At the same time, compound 3 showed selective toxicity toward cancer cells and was inactive (i.e., nontoxic) against normal cells (VERO). Compound 3 induced sub-G1 cell cycle arrest and apoptosis in B16F10 cells by down-regulating NF-κB, c-jun, Bcl-2, and by activating caspase-3 and Bax expression. Compound 3 also demonstrated beneficial effects in a clinically relevant B16F10 allograft mice model, with significant reduction of tumor growth/tumor weight in vivo. Compound 3 improved the survival rate in comparison to the control group and the cisplatin group. At the same time, compound 3 had a better safety profile than cisplatin in terms of hematological parameters and liver enzyme levels.
