A new series of 4-aminopyridyl-based lead inhibitors targeting Trypanosoma cruzi CYP51 (TcCYP51) has been developed using structure-based drug design as well as structure-property relationship (SPR) analyses. The screening hit starting point, LP10 (KD ≤ 42 nM; EC50 of 0.65 µM), has been optimized to give the potential leads 14t, 27i, 27q, 27r, and 27t, that have low nanomolar binding affinity to TcCYP51 and significant activity against T. cruzi amastigotes cultured in human myoblasts (EC50 = 14–18 nM for 27i and 27r). Many of the optimized compounds have improved microsome stability, and most are selective against human CYPs 1A2, 2D6 and 3A4 (<50% inhibition at 1 µM). A rationale for the improvement of microsome stability and selectivity of inhibitors against human metabolic CYP enzymes is presented. In addition, the binding mode of 14t with the T. brucei CYP51 (TbCYP51) ortholog has been characterized by x-ray structure analysis.
