4-Aminophenylmercuric acetate (CH3CO2HgC6H4NH2, also known as 4-(Acetoxymercurio)aniline or APMA), is an organomercurial compound and thiol-blocking reagent used in experimental biology and chemistry to activate matrix metalloproteinases and collagenase proteolytic enzymes. [1] [2] The material is highly toxic.
APMA has a molecular weight of 351.8 g/mol and appears as a white powder with a slight yellowish cast. Its melting temperature is 163–165 °C. [3] APMA is soluble in water to concentrations as high as 5 mM, and in DMSO to concentrations of 10 M or more. In 100% acetic acid, an APMA solution of 50 mg/mL is a light translucent yellow. [3]
APMA is known to activate matrix metalloproteinase enzymes and collagenase. [4] APMA activates proteolytic enzymes by reacting with cysteines at the amino terminal domains that bind zinc, near the location of the enzyme active site. [4]
APMA and APMA vapors are highly toxic or fatal in contact with skin, or if inhaled or swallowed. [3]
