Abstact

Dipeptidyl peptidase IV (DPP-4) inhibition is suitable mechanism for once daily oral dosing regimen because of its low risk of hypoglycemia. We explored linked bicyclic heteroarylpiperazines substituted at the γ-position of the proline structure in the course of the investigation of l-prolylthiazolidines. The efforts led to the discovery of a highly potent, selective, long-lasting and orally active DPP-4 inhibitor, 3-[(2S,4S)-4-[4-(3-methyl-1-phenyl-1H-pyrazol-5-yl)piperazin-1-yl]pyrrolidin-2-ylcarbonyl]thiazolidine (8 g), which has a unique structure characterized by five consecutive rings. An X-ray co-crystal structure of 8 g in DPP-4 demonstrated that the key interaction between the phenyl ring on the pyrazole and the S(2) extensive subsite of DPP-4 not only boosted potency, but also increased selectivity. Compound 8 g, at 0.03 mg/kg or higher doses, significantly inhibited the increase of plasma glucose levels after an oral glucose load in Zucker fatty rats. Compound 8 g (teneligliptin) has been approved for the treatment of type 2 diabetes in Japan.
