Tags: Trifluoroacetic acid-promoted Wagner-Meerwein rearrangement of betulonic acid carboxamide led to the formation of the expected 19,28-lactam along with a new germanicane-type 3-oxo-19-trifluoroacetoxy-18H-oleane-28-oic acid. The structure of this triterpenoid was confirmed by 2D NMR analyses. A primary evaluation of biological potency revealed an anticancer activity with GI50 < 5 M against leukemia, colon cancer, breast cancer, and prostate cancer cell lines, while the parent compounds were not active., triterpenoids; lupane; betulin; oleanane; allobetulin; germanicane; Wagner–Meerwein rearrangement; cytotoxic activity; NCI-60
