The antiparasitic activity of azole and new 4-aminopyridine derivatives has been investigated. The imidazoles 1 and 3-5 showed a potent in vitro antichagasic activity with IC50 values in the low nanomolar concentration range. The (S)-1, (S)-3, and (S)-5 enantiomers showed (up to) a thousand-fold higher activity than the reference drug benznidazole and furthermore low cytotoxicity on rat myogenic L6 cells.
