An insight into tetrahydro-β-carboline-tetrazole hybrids: synthesis and bioevaluation as potent antileishmanial agents.

A series of 2,3,4,9-tetrahydro-β-carboline tetrazole derivatives () have been synthesized utilizing the Ugi multicomponent reaction and were identified as potential antileishmanial chemotypes. Most of the screened derivatives exhibited significant activity against the promastigote (IC from 0.59 ± 0.
