GSK1292263 is a GPR119 agonist and has been investigated for the treatment of DIABETES MELLITUS, TYPE 2.

In male Sprague-Dawley rats, GSK-1292263 (3-30 mg/kg) was associated with increased levels of gastrointestinal peptides, including glucagon-like peptide 1, oxyntomodulin, peptide YY, and glucagon, especially in the absence of nutrients. This increase was further enhanced by oral glucose administration during glucose tolerance tests. In a 6-week study on Zucker diabetic fatty rats, GSK-1292263 led to a statistically significant increase in insulin immunoreactivity in pancreatic sections compared to the blank control. Furthermore, in a hyperinsulinemic-normoglycemic clamp experiment in Sprague-Dawley rats, GSK-1292263 (10/30 mg/kg) stimulated glucagon secretion without raising blood glucose levels when administered 2 hours before insulin injection, in comparison to the vehicle control.

Utilizing Hypo1, GSK-1292263 was identified from a pool of 1,538 compounds. The Fit-Value of GSK-1292263 corresponding to Hypo1 and its estimated value were 8.8 and 7.7 nM, respectively.

FTase and GGTase I Activity Assay: FTase and GGTase I activities from 60,000×g supernatants of human Burkitt lymphoma (Daudi) cells are assayed. Inhibition studies are performed by determining the ability of Ras CAAX peptidomimetics to inhibit the transfer of [3H]farnesyl and [3H]geranylgeranyl from [3H]farnesylpyrophosphate and [3H]geranylgeranylpyrophosphate to H-Ras-CVLS and H-Ras-CVLL, respectively.
