Arylanthranilodinitriles: a new biaryl class of antileishmanial agents.

Abstract A series of anthranilodinitrile-based biaryls were synthesized and evaluated in vitro against extracellular promastigotes and intracellular amastigotes of Leishmania donovani . Among various screened compounds, a biaryl with trifluoromethyl group 5f showed 83% inhibition against promastigotes and 70% inhibition against amastigotes of L. donovani at 8 and 20 μg/mL concentrations, respectively.
