製品説明 Sitagliptin (MK-0431) is an oral and highly selective DPP-4 inhibitor with an IC50 of 18 nM. It is used for the treatment of type 2 diabetes.
Targets
DPP-4 [1]
(Cell-free)
18 nM
In Vitro
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)[1]. MK0431 reduces in vitro migration of isolated splenic CD4 T-cells through a pathway involving cAMP/PKA/Rac1 activation[2]. 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[3].

実験の流れ

CD4+ T-cells (1 × 106 cells) were plated on membrane inserts (8-μm pore size) in serum-free RPMI 1640 medium. Cell migration was assayed using Transwell chambers in media ± purified porcine kidney DPP-IV (32.1 units/mg; 100 mU/ml final concentration) ± sitagliptin (100 μmol/l) or human GIP (100 nmol/l) or human GLP-1 (100 nmol/l). After 1 h, cells on the upper surface were removed mechanically and migrated cells in the lower compartment were counted.

In Vivo
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[1]. 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[4]. 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[5]. 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[6].
