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.

== Function ==
 +
[[https://www.uniprot.org/uniprot/PYGM_RABIT PYGM_RABIT]] Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.
