The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about Synthesis of (S)- and (R)-3-hydroxy-4-butanolide and (2S,4S)-, (2R,4S)-, (2S,4R)-, and (2R,4R)-2-hydroxy-4-(hydroxymethyl)-4-butanolide and their satiety and hunger modulating activities, the main research direction is hydroxybutanolide preparation appetite depressant; butanolide hydroxymethyl hydroxy appetite stimulant; hunger modulator hydroxybutanolide.COA of Formula: C4H6O3.
Two endogenous γ-lactones, 3-hydroxy-4-butanolide (I) and 2-hydroxy-4-hydrtoxymethyl-4-butanolide (II) have been identified as substances that enhance, resp., satiety and hunger by their effects on the feeding behavior and the central neurons of rats. All the stereoisomers of these two lactones were synthesized and their effects on the feeding behavior and humoral factors were assessed by infusion into the rat third cerebroventricle. Among four isomers, (2S,4S)-II was most effective in eliciting the feeding and caused potent hypoglycemia with hyperinsulinemia. (S)-I suppressed the food intake more potently than the antipode and caused humoral responses reciprocal to those of (2S,4S)-II. Thus, (S)-I and (2S,4S)-II are physiol. active forms for conveying intrinsic signals of satiety and hunger to neurons in the hypothalamus.
There is still a lot of research devoted to this compound(SMILES：O=C1OC[C@H](O)C1)COA of Formula: C4H6O3, and with the development of science, more effects of this compound(58081-05-3) can be discovered.
