Descrição geral
γ-Thiobutyrolactone undergoes copolymerization with glycidyl phenyl ether to form poly(ester-alt-sulfide).
Aplicação
γ-Thiobutyrolactone was used to terminate the ring opening polymerization of ω-pentadecalactone to synthesize difunctional polyesters. γ-Thiobutyrolactone was used to study the mechanism of metabolism of sulphur containing heterocyclic compounds by lignin-degrading basidiomycete Coriolus versicolor.

Homocysteine thiolactone (tHcy) is deemed a risk factor for cardiovascular diseases and strokes, presumably because it acylates the side chain of protein lysine residues ("N-homocysteinylation"), thereby causing protein damage and autoimmune responses. We analysed the kinetics of hydrolysis and aminolysis

Poly(ester-alt-sulfide) (polymer 1) was synthesized by the alternating copolymerization of glycidyl phenyl ether (GPE) with gamma-thiobutyrolactone (TBL) catalyzed by either quaternary onium salts or crown ether complexes. The copolymerization proceeded to produce polymer 1 with good yields in neat or

Effects of alkyl-substituted gamma-butyrolactones and gamma-thiobutyrolactones on [35S]t-butylbicyclophosphorothionate (35S-TBPS) dissociation from the picrotoxinin receptor were studied. Unlike picrotoxinin, these lactones accelerated the dissociation rate of 35S-TBPS. Thus, previous reports that these lactones change the Kd but not the Bmax of
