Eighteen analogues of an active natural chalcone were synthesized using xanhoxyline and some derivatives, and these analogues were tested for selective activity against both promastigotes and intracellular amastigotes of Leishmania amazonensis in vitro. Three analogues (10, 12, and 19) containing nitro, fluorine or bromine groups, respectively, displayed increased selective activity against the parasites as compared with the natural chalcone. The nitrosylated chalcone 10 was also tested intralesionally in infected mice and was found to be as effective as Pentostan reference drug at a dose 100 times higher than that of the chalcone in controlling both the lesion growth and the parasite burden.
