A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Formula: C5H9NO2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 344-25-2, Name is H-D-Pro-OH, molecular formula is C5H9NO2. In a Article, authors is Fuelep, Guenther H.，once mentioned of 344-25-2
We synthesized proline and pyrrolidine-2-alkanoic acid derivatives in their enantiomerically pure form and evaluated them for their affinity to the GABA transport proteins GAT-1 and GAT-3. Among the compounds presented herein, (R)-pyrrolidine-2-acetic acid (R)-4d substituted with a 2-[tris(4-methoxyphenyl)methoxy]ethyl residue at the nitrogen atom showed the highest affinity at GAT-3 (IC50 = 3.1 muM) comparable with the well-known GAT-3 blocker (S)-SNAP-5114. Compound (R)-4d displayed excellent subtype selectivity for GAT-3 (GAT-3:GAT-1 = 20:1). (S)-2-pyrrolidineacetic acid derivatives (S)-4b provided with a 4,4-diphenylbut-3-en-1-yl moiety and (S)-4c substituted with a 4,4-[di(3-methylthiophen-2-yl)]phenylbut-3-en-1-yl residue at the nitrogen atom exhibited IC50 values of 0.396 muM and 0.343 muM at the GAT-1 protein, respectively.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Formula: C5H9NO2
