The discovery of nitrile compound 4, a potent inhibitor of Cathepsin K (Cat K) with good bioavailability in dog is described. The compound was used to demonstrate target engagement and inhibition of Cat K in an in vivo dog PD model. The margin to hERG ion channel inhibition was deemed too low for a clinical candidate and an optimisation program to find isosteres or substitutions on benzothiazole group led to the discovery of 20, 24 and 27; all three free from hERG inhibition.

A series of (4β-substituted)-l-prolylpyrrolidine analogs lacking the electrophilic nitrile function were synthesized and their dipeptidyl peptidase IV (DPP-IV) inhibitory activity and duration of ex vivo activity were evaluated. Structural optimization of a N-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine analog 8, which was found by high-speed analog synthesis, was carried out to improve the potency and duration of action. A representative compound 26 was evaluated to assess its effect on the plasma glucose level after the oGTT (oral glucose tolerance test) in normal rats. Structure-activity relationships (SAR) are also presented.
