Pepstatin A

Pepstatin A is a competitive, reversible aspartic protease inhibitor and inhibits proteases such as pepsin, chymosin, renin, HIV proteases, and cathepsins D and E. Peptstatin A is highly selective and is often used in a mixture with other enzyme inhibitors.In vitrostudies have shown pepstatin A is the only aspartic acid inhibitor that exhibits inhibitory effects on HIV proteases.Pepstatin A is effective at inhibiting most affected proteases at a concentration of 1μM, but can inhibit pepsin at the picomolar range of concentrations. It is believed to function by way of a collected-substrate inhibition mechanism. Pepstatin A may also suppress differentiation of osteoclasts by inhibiting phosphorylation of MAP kinase and inhibiting NFATc1 expression.Product SpecificationsPepstatin AMOLECULAR BIOLOGY GRADEFormula: C34H63N5O9MW: 685.89 g/molPubChem Chemical ID:5478883
