Dipeptidyl Peptidase

The major metabolic pathway of vildagliptin in mice rats dogs and humans is hydrolysis at the cyano group to produce a carboxylic acid metabolite M20 7 (LAY151) whereas the major metabolic enzyme of vildagliptin has not been identified In the present study we determined the contribution rate of dipeptidyl peptidase-4 (DPP-4) to the hydrolysis of vildagliptin in the liver

HtrA1 serine protease inhibits signaling mediated by Tgfβ

HtrA1 a member of the mammalian HtrA serine protease family has a highly conserved protease domain followed by a PDZ domain Because HtrA1 is a secretory protein and has another functional domain with homology to follistatin we examined whether HtrA1 functions as an antagonist of Tgfβ family proteins During embryo development mouse HtrA1 was expressed in specific areas where signaling by
