A novel series of urea-based peptidomimetic calpain inhibitors was written by Sanders, M. Lee;Donkor, Isaac O.. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2006.HPLC of Formula: 87694-53-9 This article mentions the following:
A series of peptide aldehyde derivatives in which the P2 chiral carbon has been replaced with nitrogen were synthesized as urea-based peptidomimetic inhibitors of μ-calpain. The compounds mirrored the general SAR of peptidyl aldehyde calpain inhibitors but displayed greater selectivity for μ-calpain over cathepsin B. 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: 87694-53-9HPLC of Formula: 87694-53-9).
(S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.HPLC of Formula: 87694-53-9
