Synthesis, Structural Characterization and In Vitro Leishmanicide and Antifungal Activities Studies of Schiff Base Compounds

N, N'-bis (2-nitrophenyl methylene)hexane-1,6-diamine, N, N'-bis (4- nitrophenylmethylene)benzene-1,3-diamine, N, N'-bis (p-nitrophenylmethylene) cyclohexane- 1,2-diamine were synthesize and have been characterized by conventional spectrometry methods (NMR, IR and HR-ESI-MS). Antileishmanicide and antifungal screening showed that, N, N'-bis (2-nitrophenyl methylene) hexane- 1,6-diamine, with MIC of 16.40 mg/L and 125 mg /L respectively, is the most active.
