Starting from 3-amino-5-(2-hydroxyphenyl) amino acid coupled triazoles 1a-e, new 3-(2-hydroxyphenyl)-3H-imidazo[2,1-c][1,2,4]triazol-6(5H)-one 2a,b, 3b,d, 6a and 3-N-arly(alkyl) amino acid coupled triazoles 4b,d, 7a,c,d,e have been synthesized as potential antileishmanial agents. The structures of the newly synthesized compounds were confirmed using elemental and spectral analyses (FT-IR, 1H-NMR, 13C-NMR and MS). The in vitro antileishmanial potency of the synthesized compounds was evaluated compared to Amphotericin B deoxycholate and miltefosine as lead references. Compounds 2b, 7d and 7e showed perfect IC50 values corresponding to amphotericin B and more patent than miltefosine against L. aethiopica promastigotes.
