Introduction. Gamma-butyrolactone (GBL) is a small, lipophilic molecule that readily absorbs in the body when consumed orally. In vitro, GBL and gamma-hydroxybutyrate (GHB) are subject to interconversion depending on the pH (). In vivo, GBL is a precursor to GHB, an endogenous chemical that is found in low concentrations in the body.GBL is rapidly …

1 Introduction. All living organisms rely on basic carbon-containing compounds—primarily sugars, lipids, amino acids, organic acids and polyols—as carbon skeletons, energy sources and cellular signals and the acquisition of carbon fixed by host-plant photosynthesis is a prerequisite for the growth and proliferation of plant pathogenic microbes.

Gamma-Butyrolactone (γ-butyrolactone) is a small molecule compound that is designed to inhibit the activity of GCN5. It is inspired by the theory that it should have hydrogen-bond acceptor properties for Cys177 and polar group interaction with Glu173 in GCN5, while also possessing an aliphatic side chain similar to lysine.
