Beta-carboline-3-carboxamide derivatives as promising antileishmanial agents.

Ann Trop Med Parasitol 2011 Dec;105(8):549-57

Universidade Estadual de Londrina, Rodovia Celso Garcia Cid, Campus Universitário, Londrina, Paraná, Brazil.

Leishmaniasis has an overwhelming impact on global public health especially in tropical and subtropical countries and the currently available antileishmanial drugs have serious side effects and low efficacy. Natural and synthetic compounds have been tested in the past few years against Leishmania and the beta-carboline class of compounds have shown great results in antiparasitic chemotherapy. In the present study, three 1-substituted beta-carboline-3-carboxamides (3-5) and 1-substituted beta-carboline-3-carboxylic acid (2) were synthesized and screened for in vitro activity against L.
