Crystal structure of rabbit muscle glycogen phosphorylase in complex with 3,4-dihydro-2-quinolone


Overview

A series of substituted 3,4-dihydro-2-quinolone glycogen phosphorylase inhibitors, which have potential as antidiabetic agents, is described. Initial members of the series showed good enzyme inhibitory potency but poor physical properties. Optimisation of the 1-substituent led to 2,3-dihydroxypropyl compounds which showed good in vitro potency and improved physical properties, together with good DMPK profiles and acute in vivo efficacy in a rat model. X-ray crystallographic data are presented, showing an unexpected variety of binding orientations at the dimer interface site.

About this Structure

2IEG is a Single protein structure of sequence from Oryctolagus cuniculus. Full crystallographic information is available from OCA.
