Bestatin methyl ester is a cell-permeable derivative of Bestatin which displays slightly stronger inhibition of neutral aminopeptidase than Bestatin, but has much weaker activity against basic aminopeptidase. Bestatin methyl ester also augments Fas- or TNF-alpha-induced apoptosis in solid tumor cell lines. Bestatin methyl ester is a synthetic compound derived from the amino acid leucine. It has found application in research exploring the influence of enzymes on proteins.
