D-Val-Leu-Lys-pNA dihydrochloride D-Val-Leu-Lys-p-itoailide dihydrochloride; D-VLK-pNA dihydrochloride; S 2251 dihydrochloride	Fluorescent Dye	Others
D-Val-Leu-Lys-pNA dihydrochloride (D-VLK-pNA dihydrochloride) is a colorimetric substrate for plasminolytic activity. D-Val-Leu-Lys-pNA dihydrochloride is catalytically bound and hydrolyzed by plasmin to release p-nitroaniline (pNA), which can be detected colorimetrically at 405 nm as a measure of plasminolytic activity .

L-Leucyl-4-nitroanilide hydrochloride	Biochemical Assay Reagents	Others
L-Leucyl-4-nitroanilide hydrochloride is a commonly used substrate in various biochemical assays to measure the activity of enzymes that cleave peptide bonds, such as proteases. L-Leucine p-nitroanilide hydrochloride has unique chemical properties that allow it to be cleaved by these enzymes to form a yellow product called p-nitroaniline. This makes it a useful tool for detecting and quantifying protease activity in biological samples such as blood or tissue extracts.

Arachidonoyl p-nitroaniline	Others	Others
Arachidonoyl p-nitroaniline is a substrate for the hydrolysis of p-nitroaniline by FAAH in Dictyostelium discoideum with long-chain unsaturated fatty acids. Arachidonoyl p-nitroaniline can be used in enzyme kinetic studies. Examples include determining the hydrolysis rate of Arachidonoyl p-nitroaniline and analyzing the fatty acid amide hydrolase activity of recombinant His-FAAH purified from Dictyostelium to characterize the binding and catalytic specificity of mammalian FAAH enzymes .

HY-120971

N-Decanoyl p-Nitroaniline DepNA	Endogenous Metabolite	Metabolic Disease
N-Decanoyl p-nitroaniline (DepNA) is one of several nitroaniline fatty acid amides which can be used to measure fatty acid amide hydrolase (FAAH) activity.1 FAAH is a relatively unselective enzyme in that it accepts a variety of amide head groups other than the ethanolamine of its endogenous substrate anandamide (AEA). It also will hydrolyze fatty acid amides with fewer carbons and fewer double bonds than arachidonate. Exposure of DepNA to FAAH activity results in the release of the yellow colorimetric dye p-nitroaniline (ε=13,500 at 410 nm). This allows the fast and convenient measurement of FAAH activity using a 96 well plate spectrophotometer.
