A novel series of 5-(5-nitrofuran-2-yl)-and 5-(5-nitrothiophen-2-yl)-1,3,4-thiadiazole-2-amines bearing acyclic amine at C-2 position of thiadiazole ring were synthesized and evaluated in vitro against promastigote and amastigote forms of Leishmania major. The structure-activity of series was investigated by studying 40 compounds. The most active derivatives were hydroxypropylamino-and methoxypropylamino-analogs of 5-(5-nitrothiophen-2-yl)-1,3,4-thiadiazole (compounds 29 and 32, respectively) with highest selectivity index (SI > 12).
