p-aminophenylmercuric acetate

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[1][2][3].
