(S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 87694-53-9

Design and synthesis of novel protease inhibitors. Tripeptide α’,β’-epoxyketones as nanomolar inactivators of the proteasome was written by Spaltenstein, Andrew;Leban, Johann J.;Huang, Jim J.;Reinhardt, Kelli R.;Viveros, O. Humberto;Sigafoos, Jim;Crouch, Ronald. And the article was included in Tetrahedron Letters in 1996.Product Details of 87694-53-9 This article mentions the following:

Tripeptide epoxy ketones I and II (Z = PhCH2O2C) were prepared stereospecifically starting from N-tert-butoxycarbonyl-L-phenylalanine. Diastereomer I inhibited the chymotrypsin-like activity of porcine endothelial cell derived proteasome at low nanomolar concentrations In the experiment, the researchers used many compounds, for example, (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9Product Details of 87694-53-9).
