Amastatin, also known as 3-amino-2-hydroxy-5-methylhexanoyl-L-valyl-L-valyl-L-aspartic acid, is a naturally occurring, competitive and reversible aminopeptidase inhibitor that was isolated from Streptomyces sp. ME 98-M3.[1] It specifically inhibits leucyl aminopeptidase, alanyl aminopeptidase (aminopeptidase M/N), bacterial leucyl aminopeptidase (Aeromonas proteolytica aminopeptidase), leucyl/cystinyl aminopeptidase (oxytocinase/vasopressinase),[2] and, to a lesser extent, glutamyl aminopeptidase (aminopeptidase A),[3] as well as other aminopeptidases.[4] It does not inhibit arginyl aminopeptidase (aminopeptidase B).[5][6] Amastatin has been found to potentiate the central nervous system effects of oxytocin and vasopressin in vivo.[7] It also inhibits the degradation of met-enkephalin, dynorphin A, and other endogenous peptides.[8]
