Synthesis of montbretin A analogues yields potent competitive inhibitors of human pancreatic α-amylase

Chem Sci. 2019 Oct 18;10(48):11073-11077. doi: 10.1039/c9sc02610j. eCollection 2019 Dec 28.

Abstract

Simplified analogues of the potent human amylase inhibitor montbretin A were synthesised and shown to bind tightly, K I = 60 and 70 nM, with improved specificity over medically relevant glycosidases, making them promising candidates for controlling blood glucose. Crystallographic analysis confirmed similar binding modes and identified new active site interactions.
