 P32/98 Biological Activity

Description P32/98 hemifumarateis a potent inhibitor of dipeptidyl peptidase IV with a Ki value of 130 nM. P32/98 hemifumarate improves glucose tolerance, insulin sensitivity and β-cell responsiveness in fatty Zucker rat model[1][2][3].

Target

DPP-IV:130 nM (Ki)

In Vitro GLP-1 acts function of stimulation of glucose dependent insulin secretion and induction of satiety feelings, and DPPIV is the major renal catabolic pathway for GLP-1 in vivo[2]. P32/98 hemifumarate, together with 200 pM GLP-1, (10 μM; 3 h) shows no significant inhibition of sodium re-absorption in porcine proximal tubular cells[2]. P32/98 hemifumarate (10 μM; 96 h) does not influence the mRNA expression of GLP-1R, DPPIV, Na+/H+ exchanger isoform 3 (NHE3), sodium-dependent glucose transporter slc5a1, slc5a2 (SGLT1, 2)[2]. Cell Cytotoxicity Assay[2] Cell Line: Porcine proximal tubular cells Concentration: 10 μM Incubation Time: 96 hours Result: Showed no toxic.
In Vivo P32/98 hemifumarate (25 mg/kg; i.g.; once daily) long-time treatment significantly improves the glucose tolerance in Zucker diabetic fatty rats, a model of IGT (impaired glucose tolerance)[3]. Animal Model: Zucker diabetic fatty rat[3] Dosage: 25 mg/kg Administration: Oral gavage; once daily Result: Significantly improved the glucose tolerance in Zucker diabetic fatty rats.
