Abstract
We recently reported the medicinal chemistry reoptimization of a known human tyrosine kinase inhibitor, lapatinib, against a variety of parasites responsible for numerous tropical diseases, including human African trypanosomiasis ( Trypanosoma brucei), Chagas disease ( T. cruzi), Leishmaniasis ( Leishmania spp.), and malaria ( Plasmodium falciparum). Herein, we report our continuing efforts to optimize this series against P. falciparum. Through the design of a library of compounds focused on reducing the lipophilicity and molecular weight, followed by an SAR exploration, we have identified NEU-1953 (40). This compound is a potent inhibitor of P. falciparum with an improved ADME profile over the previously reported compound, NEU-961 (3).
