2-Aminoacetophenone hydrochloride
CAS:Controlled Product2-Aminoacetophenone hydrochloride is a chemical compound that is used in analytical chemistry as a reagent for the determination of protein and amino acid concentrations. This reagent can be prepared in various forms, depending on the type of analysis being performed. 2-Aminoacetophenone hydrochloride is used to determine the concentration of free amino acids in a sample by binding to it. It can also be used for determining the concentration of bound amino acids by reacting with them with hydrochloric acid. 2-Aminoacetophenone hydrochloride is an excellent substrate for matrix effect, which may cause errors in measurement due to interference from other substances present in the sample. The use of light exposure reduces this problem by removing interfering substances from the sample.

Discontinued productAcetyl-Pepstatin Ac-Val-Val-Sta-Ala-Sta-OH
CAS:Acetyl-Pepstatin is a protein data inhibitor that binds to the active site of enzymes, inhibiting their function. Acetyl-pepstatin has been shown to inhibit cathepsin D, chymotrypsin, and trypsin. It also inhibits the activity of proteases in the stomach and intestinal tract. Acetyl-Pepstatin is used as an anti-inflammatory drug for the treatment of chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF). The inhibition of these enzymes reduces inflammation by preventing the activation of inflammatory cytokines. It also prevents collagen from being degraded by proteases, which leads to decreased degradation of cartilage by chondrocytes. This drug's mechanism is similar to that of acetylsalicylic acid (aspirin), in that it inhibits prostaglandin synthesis.br>
