Herein, we describe the design and synthesis of a series of C-5-substituted diazenyl derivatives of uracil, exhibiting selective and potent antileishmanial but not antibacterial or antifungal activity. The formation of the substituted derivatives was confirmed by using FTIR, H, C NMR, and HRMS analysis. Among all of the sets of tested compounds, only three [, and ] showed the highest activity against (LD) promastigote and amastigote models of LD infections.
