AMASTATIN HYDROCHLORIDE

The Uses of AMASTATIN HYDROCHLORIDE

Amastatin is a slow, tight binding, competitive aminopeptidase (AP) inhibitor, first described as an inhibitor of human serum AP-A (glutamyl AP; IC50 = 0.54 μg/ml) but not of AP-B (arginine AP). It also inhibits AP-N (AP-M, alanyl AP; Ki = 20-200 nM), leucyl-cystinyl AP (Ki = 20-220 nM), and endoplasmic reticulum AP 1 (Ki = 41.8 μM). Amastatin is without effect on trypsin, papain, chymotrypsin, elastase, pepsin, or thermolysin.[Cayman Chemical]

What are the applications of Application

Amastatin hydrochloride is a competitive inhibitor of several aminopeptidases

General Description

Chemical structure: peptide

Biochem/physiol Actions

It inhibits cytosolic leucine aminopeptidase (EC.3.4.11.1), microsomal aminopeptidase M (EC.3.4.11.2) and bacterial leucine aminopeptidase (EC.3.4.11.10). It is less effective against aminopeptidase A (EC 3.4.11.7), the enzyme that converts angiotensin II to angiotensin III. Potentiates the CNS effects of vasopressin and oxytocin in vivo.Effective concentration: 1-10 μM.
