Chemical Properties,Uses,Production

Uses

Stephacidin B is a fungal metabolite. Stephacidin B shows in vitro cytotoxicity against a panel of human tumor cell lines. Stephacidin B shows the strongest cytotoxicity against testosterone-dependent prostate LNCaP cancer cells[1].

Biological Activity

Stephacidin B is a fungal metabolite that has been found in A. ochraceus.1 Dimeric stephacidin B is rapidly converted to a monomer, avrainvillamide , in vitro.2 Stephacidin B is cytotoxic to a variety of cancer cells, including testosterone-independent PC3 and -sensitive LNCaP prostate cancer cells (IC50s = 0.37 and 0.06 μM, respectively) and estradiol-independent SK-BR-3 and -sensitive MCF-7 breast cancer cells (IC50s = 0.32 and 0.27 μM, respectively).1 It induces apoptosis in HepG2 and Huh7 hepatocellular carcinoma cells when used at a concentration of 4 μM.3
