Descripción

Aplicación

Chymostatin has been used in a study that determined that molecular calculations are useful for evaluating the interactions between ligands, including inhibitors and homologous enzymes, in docking models. Chymostatin has also been used in a study to investigate the norovirus protease as an attractive target for antiviral drug development.

Acciones bioquímicas o fisiológicas

Inhibits the lysosomal proteinase cathepsin B, and the soluble Ca²⁺-activated proteinase. Many young plant tissues express a chomostatin-sensitive serine protease.

Chymostatin is a strong inhibitor of many proteases, including chymotrypsin, papain, chymotrypsin-like serine proteinases, chymases, and lysosomal cysteine proteinases such as cathepsins A,B,C, B, H, and L. It weakly inhibits human leucocyte elastase. It is effective at a final concentration of 100 to 200 μg/ml (10 to 100 μM). Chymostatin is often included in protease inhibitor cocktails used with plant extracts.

Nota de preparación

Solubility testing in glacial acetic acid at 10 mg/ml yields a clear solution, which is usually colorless, but can be yellow in appearance. It is reportedly also soluble in DMSO; only slightly soluble in water and short-chain alcohols; insoluble in ethyl acetate, butyl acetate, ether, hexane, and petroleum ether. Stock solutions (10 mM) can be prepared in DMSO and are stable for months at -20 °C. Stock solutions can also be made in 0.1 M HCl. Dilute solutions (10-100 μM) are only stable for several hours, due to oxidation of the terminal aldehyde.
