Popis: The tetrahydroprotoberberine alkaloids 5 and 7 possessing a trans-quinolizidine conformation display in vitro KB cytotoxicities in contrast to their corresponding diastereomers 4 and 6 which exist in the cis-quinolizidine conformation and are much less toxic. The DNA-binding parameters of these compounds as well as the protoberberine salts 1, 8, and 9 have been examined by equilibrium dialysis. Only the quaternary salts bind to DNA. The alcohol 5 showed low in vivo activity against leukemia P388 systems, while the quaternary salts 8 and 9 proved to be toxic to the host.
