Synthesis of marine alkaloid: 8,9-Dihydrocoscinamide B and its analogues as Novel class of antileishmanial agents

A series of marine alkaloid 8,9-dihydrocoscinamide B, its analogues and indolylglyoxylamide derivatives have been synthesized and screened for their in vitro antileishmanial activity profile in promastigote and amastigote models. Compounds 7 and 10 have shown 99–100% inhibition against promastigotes and 97–98% inhibition against amastigotes at a concentration of 10 μg/ml.
