Synthesis and glucose-stimulate insulin secretion (GSIS) evaluation of vindoline derivatives

Bioorg Med Chem Lett. 2017 Mar 1;27(5):1316-1318. doi: 10.1016/j.bmcl.2016.09.064. Epub 2016 Sep 28.

Abstract

It is demonstrated that natural product vindoline can enhance the glucose-stimulated insulin secretion (GSIS) in MIN6 cells with the EC50 value of 50.2μM. In order to improve the activities, a series of vindoline derivatives are synthesized and evaluated in MIN6 cells. Compounds 4, 8, 17 and 24 show about 4.5 times more effective stimulation insulin secretion ability (EC50: 10.4, 14.2, 11.0 and 12.7μM, respectively) than vindoline.

Keywords: Glucose-stimulate insulin secretion (GSIS); Natural product; Structure–activity relationships (SARs); Vindoline.
