N-acylimidazole derivatives of betulin and betulinicacid (14–29) have been synthesized. The new compounds were screened for in vitro cytotoxicity activity against human cancer cell lines HepG2, Jurkat and HeLa. A number of compounds have shown IC50 values lower than 2 μM against the cancer cell lines tested and the vast majority has shown a better cytotoxicity profile than betulinicacid, including the
