Safety of Ethyl indoline-2-carboxylate. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Ethyl indoline-2-carboxylate, is researched, Molecular C11H13NO2, CAS is 50501-07-0, about Computational analysis of chiral recognition in Pirkle phases. Author is Lipkowitz, Kenny B.; Baker, Brian.

The relative retention orders and chromatog. separability factors for optical analytes on 2 com. available chiral stationary phases have been determined from statistical mol. modeling. The intermmol. potential-energy surfaces of the diastereomeric complexes formed between the chiral receptor and mirror image substrates are flat and reveal that both enantiomers tend to dock in the same general region around the receptor. How the receptor senses differences between mirror image analytes (enantiorecognition) is revealed with an algorithm that partitions the total binding energy into mol. fragments on the receptor. The fragments on the receptor most responsible for substrate binding are located and the fragments most responsible for enantioselection are discovered. The fragment bearing the stereogenic centers is generally not the most cognizant of differences between mirror image substrates, and the results are generally in agreement with previously proposed chiral recognition models.

As far as I know, this compound(50501-07-0)Safety of Ethyl indoline-2-carboxylate can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

Monoacylglycerol lipase (MAGL) is a principal metabolic enzyme responsible for hydrolyzing the endogenous cannabinoid (endocannabinoid) 2-arachidonoylglycerol (2-AG). Selective inhibitors of MAGL offer valuable probes to further understand the enzyme’s function in biol. systems and may lead to drugs for treating a variety of diseases, including psychiatric disorders, neuroinflammation, and pain. N-Hydroxysuccinimidyl (NHS) carbamates have recently been identified as a promising class of serine hydrolase inhibitors that shows minimal cross-reactivity with other proteins in the proteome. Here, the authors explore NHS carbamates more broadly and demonstrate their potential as inhibitors of endocannabinoid hydrolases and addnl. enzymes from the serine hydrolase class. The authors extensively characterize an NHS carbamate MJN110 as a potent, selective, and in-vivo-active MAGL inhibitor. Finally, the authors demonstrate that MJN110 alleviates mech. allodynia in a rat model of diabetic neuropathy, marking NHS carbamates as a promising class of MAGL inhibitors.
