The Uses of H-LEU-4M-BETANA HCL

L-Leucine 4-methoxy-β-naphthylamide is a cell-permeable substrate for aminopeptidase M and leucine aminopeptidase that was developed for intracellular analysis of protease activities.

in vitro

l-leucine 4-methoxy-β-naphthylamide was identified as a cell-permeable substrate for aminopeptidase m and leucine aminopeptidase that was developed for intracellular analysis of protease activities [1]. in a previous method-developing study, peptide derivatives of 4-methoxy-β-naphthylamine including l-leucine 4-methoxy-β-naphthylamide were incubated in microtiter plates together with nitrosalicylaldehyde. selectivity was achieved by running parallel assays containing inhibitors partially selective for each of peptide derivatives. this method was successfully validated by measurements in cells isolated from cathepsin b-/--, k-/--, and l-/-- mice [2].
