    The peptidyl prolyl cis/trans isomerase Pin1 is a promising molecular target for anti-cancer therapeutics. Here we report the structure-guided evolution of an indole 2-carboxylic acid fragment hit into a series of alpha-benzimidazolyl-substituted amino acids. Examples inhibited Pin1 activity with IC(50) <100nM, but were inactive on cells. Replacement of the benzimidazole ring with a naphthyl group resulted in a 10-50-fold loss in ligand potency, but these examples downregulated biomarkers of Pin1 activity and blocked proliferation of PC3 cells.
