Marine bisindole alkaloid: A potential apoptotic inducer in human cancer cells

European Journal of Histochemistry, 2018
Marine organisms such as corals, sponges and tunicates produce active molecules which could represent a valid starting point for new drug development processes. Among the various structural classes, the attention has been focused on 2,2-bis(6-bromo-3-indolyl) ethylamine, a marine alkaloid which showed a good anticancer activity against several tumor ...
