Cathepsin Activator

p-Aminophenylmercuric acetate is an organomercurial activator of matrix metalloproteinases (MMP). P-Aminophenylmercuric acetate participates in the activation and inhibition of MMP-8 by attacking protein sulfhydryl or inducing cysteine switching reaction. p-Aminophenylmercuric acetate promotes the shedding of betacellulin precursor (pro-BTC). p-Aminophenylmercuric acetate influences the binding of agonists and antagonists to the opiate receptor.

L-Homocysteine (Standard) is the analytical standard of L-Homocysteine. This product is intended for research and analytical applications. L-Homocysteine, an amino acid, is a homocysteine that has L configuration. Homocysteine is an essential intermediate in normal mammalian metabolism of methionine. L-Homocysteine induces upregulation of Cathepsin V that mediates vascular endothelial inflammation in hyperhomocysteinaemia[1][2].

AKR1C3-IN-17 is a cathepsin B (CTSB)-activated small molecule-drug conjugate targeting AKR1C3 with an IC₅₀ of 9 nM. AKR1C3-IN-17 is cleaved by CTSB to release the payload Gemcitabine (HY-17026). AKR1C3-IN-17 induces apoptosis and shows antitumor activity in mice. AKR1C3-IN-17 can be used for the study of hepatocellular carcinoma.

6-Hydroxytetrangulol is a CPP32 protease inducer found in Streptomyces sp.
