acid (1) exhibited weak binding activity to Bcl-xL. These compounds exhibited cytotoxicity against KB and HCT-116 cell lines with IC50 values between 10 and 30 μM. Bioconversion of compound 1 by Rhizopusarrhizus afforded new hydroxylated metabolites (3−7) of the ent-trachylobane and ent-kaurene type and compound 8, with a rearranged pentacyclic carbon framework that was named rhizopene. Compounds 3−8
