Human African Trypanosomiasis (HAT) is a severe, often fatal disease caused by the parasitic protist Trypanosoma brucei. The glycolytic pathway has been identified as the sole mechanism for ATP generation in the infective stage of these organisms, and several glycolytic enzymes, phosphofructokinase (PFK) in particular, have shown promise as potential drug targets. Herein, we describe the discovery of ML251, a novel nanomolar inhibitor of T. brucei PFK, and the structure-activity relationships within the series.

A new series of 17-(N-(arylimino)-5-pregnen-3 beta-ol derivatives 19-32 as well as carboxylate and acrylate analogues of pregnenolone 37-40 were synthesized and evaluated for their inhibitory activity against human CYP17 hydroxylase expressed in Escherichia coli. Compounds 32 and 37 were the Most potent analogues in this series, showing inhibition activity with IC50 = 2.11 and 1.29 mu M, respectively. However, the analogue 37 revealed a better selectivity profile (83.21% inhibition of hydroxylase), which is a leading candidate for further development. Molecular docking study of 37 showed binding with the amino acid residues of CYP17 through hydrogen bonds and hydrophobic interaction. (C) 2015 Published by Elsevier Inc.
