Abstract
A whole organism high-throughput screen of approximately 87,000 compounds against Trypanosoma
brucei brucei led to the recent discovery of several novel compound classes with low micromolar activity
against this organism and without appreciable cytotoxicity to mammalian cells. Herein we report a
structureeactivity relationship (SAR) investigation around one of these hit classes, the 3-(oxazolo[4,5-b]
pyridin-2-yl)anilides. Sharp SAR is revealed, with our most active compound (5) exhibiting an IC50 of
91 nM against the human pathogenic strain T.b. rhodesiense and being more than 700 times less toxic
towards the L6 mammalian cell line. Physicochemical properties are attractive for many compounds in
this series. For the most potent representatives, we show that solubility and metabolic stability are key
parameters to target during future optimisation.
