A series of thirty 1,2,3-triazolylsterols were prepared by a stereocontrolled synthesis and inspired by azasterols with proven antiparasitic activity. Ten of these compounds constitute chimeras/hybrids of AZA and 1,2,3-triazolyl azasterols. The entire library was assayed against the etiological agents of the parasites responsible of kinetoplastid diseases (L. donovani, T. cruzi and T. brucei). Several of the compounds were active at submicromolar/nanomolar concentration with excellent selectivity index, when compared to their activity in mammalian cells. Studies of the physicochemical properties in silico were conducted to rationalize the activities.
