Abstract: A sulfonamidebenzamide series was assessed for anti-kinetoplastid parasite activity based on structural similarity to the antiparasitic drug, nifurtimox. Through structure-activity optimization, derivatives with limited mammalian cell toxicity and increased potency toward African trypanosomes and Leishmania promastigotes were developed. Compound 22 had the best potency against the trypanosome (EC50=0.010μM) while several compounds showed ∼10-fold less potency against Leishmania promastigotes without impacting mammalian cells (EC50>25μM). While the chemotype originated from an unrelated optimization program aimed at selectively activating an apoptotic pathway in mammalian cancer cells, our preliminary results suggest that a distinct mechanism of action from that observed in mammalian cells is responsible for the promising activity observed in parasites.
