Synthesis and glucose-stimulate insulin secretion (GSIS) evaluation of vindoline derivatives
摘要:
It is demonstrated that natural product vindoline can enhance the glucose-stimulated insulin secretion (GSIS) in MIN6 cells with the EC50 value of 50.2 mu M. 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 12.7 mu M, respectively) than vindoline. (C) 2016 Elsevier Ltd.
