Optimization of a chemical series
originating from whole-cell phenotypic
screening against the human malaria parasite, Plasmodium falciparum, led to the identification of two promising 2,6-disubstituted imidazopyridine
compounds, 43 and 74. These compounds exhibited
potent activity against asexual blood stage parasites that, together
with their in vitro absorption, distribution, metabolism, and excretion
(ADME) properties, translated to in vivo efficacy with clearance of
parasites in the PfSCID mouse model for malaria within
48 h of treatment.
