WebAiming at generating a library of bioactive indole alkaloid derivatives as multidrug resistance (MDR) reversers, two epimeric indole alkaloids (1 and 2) were submitted to chemical transformations, giving rise to twenty-four derivatives (5-28), bearing new aromatic or aliphatic azine moieties. Webinvestigated. This bisindole alkaloid was isolated from the lipoid extract of Caulerpa racemosa and its structure was identified by spectroscopic methods, including IR and NMR techniques. The pharmacological assays used were the writhing and the hot plate tests, the formalin-induced pain, the capsaicin-induced ear edema and the carrageenan-
