17317162 Yoshida T, Sakashita H, Akahoshi F, Hayashi Y: [(S)-gamma-(4-Aryl-1-piperazinyl)-l-prolyl] thiazolidines as a novel series of highly potent and long-lasting DPP-IV inhibitors. Bioorg Med Chem Lett. 2007 May 1;17(9):2618-21. Epub 2007 Feb 8.

Of these compounds, the 4-(5-nitro-2-pyridyl) piperazine analog 21e showed a sub-nanomolar (IC (50)=0.92 nmol/L) DPP-IV inhibitory activity and a long-lasting in vivo DPP-IV inhibition profile.

Drug Metab Dispos. 2007 Apr;35(4):533-8. Epub 2007 Jan 12.

These metabolites were the N-sulfate and N-carbamoyl glucuronic acid conjugates of parent drug, a mixture of hydroxylated derivatives, an ether glucuronide of a hydroxylated metabolite, and two metabolites formed by oxidative desaturation of the piperazine ring followed by cyclization.

Approximately 10 to 16% of the radiolabeled dose was recovered in the rat and dog excreta as phase I and II metabolites, which were formed by N-sulfation, N-carbamoyl glucuronidation, hydroxylation of the triazolopiperazine ring, and oxidative desaturation of the piperazine ring followed by cyclization via the primary amine.

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.

Initial work in an alpha-amino acid series related to isoleucyl thiazolidide was discontinued due to lack of selectivity; however, SAR studies on two screening leads led to the identification of a highly selective beta-amino acid piperazine series.
