How to use

In Vitro:

Sitagliptin exhibits a > 2600-fold margin of selectivity against DPP8, DPP9, and other members of the dipeptidyl peptidase family (i.e., potency against DPP-4 vs. DPP8/9). MK0431 reduces in vitro migration of isolated splenic CD4 T-cells through a pathway involving cAMP/PKA/Rac1 activation. Sitagliptin exerts a novel, direct action in order to stimulate GLP-1 secretion by the intestinal L cell through a DPP-4-independent, protein kinase A- and MEK-ERK1/2-dependent pathway. It therefore reduces the effect of autoimmunity on graft survival.

In Vivo:

Sitagliptin is well absorbed after oral administration with a bioavailability of 87%. Sitagliptin has an apparent terminal half-life of 10–12 h at doses of 25-100 mg and is excreted mainly (≈ 80%) as unchanged compound by the kidneys. Sitagliptin does not interfere with the P450 cytochrome enzymes nor have there been any reported significant drug-drug interactions. Sitagliptin has been shown to inhibit DPP-4 activity by > 90% within 1-2 h of administration. It has a short half-life in mice (1-2 h). Chronic sitagliptin treatment in a non-geneticmouse model of type 2 diabetes elicits significant improvement in glycemic control. The improved glucose homeostasis correlates with restoration of normal islet cell (α and β cells) mass, architecture and insulin secretion capacity in response to glucose stimulation. Sitagliptin prolongs islet graft survival in streptozotocin-induced and NOD mice. Administration of sitagliptin in vivo reduces lymph node and splenic CD4+ T-cell migration, measured in vitro, via incretin- and nonincretin-mediated effects, respectively, and splenic sDPP-IV-responsive CD4+ T-cells and lymph node incretin nonresponsive CD4+ T-cells selectively infiltrated islets of diabetic NOD mice, after tail vein injection. Sitagliptin significantly suppressed epileptogenesis in PTZ (pentylenetetrazole)-induced seizures. Sitagliptin counteracted neuronal damage and all biochemical, and histo-chemical alteration induced by PTZ. Oral sitagliptin can promote hippocampal neurogenesis, counteract hippocampal oxidative stress, and prevent the decline in mice cognition.
