Background:

LAF-237 is a potent inhibitor of DDP-4 with IC50 value of 2.3 nM [1].
DDP-4 is an antigenic enzyme expressed on the surface of most cell types and is associated with signal transduction, apoptosis and immune regulation [1].
LAF-237 is a specific inhibitor of DDP4 and can reduce glycemia. When tested on Type II diabetes patients, LAF-237 inhibits the inactivation of GLP-1 by DPP-4, allowing GLP-1 to increase the secretion of insulin and decrease glucagon release [2].
In the glucose tolerance test with obese male Zucker rats, LAF-237 can significantly decrease glucose excursion and stimulates insulin secretion. There are 95% inhibition activities of DDP-4 two hours after the injection of LAF-237[3]. Through enhances beta cell replication and reduces apoptosis, LAF-237 increases in the number of beta cell and can sustain for 12 days after washout LAF-237. Also, LAF-237 can protect nerve fiber loss in STZ-induced diabetic adult male Sprague Dawley rats [4].
