AEBSF or 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride is a water-soluble, irreversible serine protease inhibitor with a molecular weight of 239.5 Da. It inhibits proteases like chymotrypsin, kallikrein, plasmin, thrombin, and trypsin. The specificity is similar to the inhibitor PMSF, nevertheless AEBSF is more stable at low pH values. Typical usage is 0.1 - 1.0 mM. AEBSF (marketed as Pefabloc SC from the company Pentapharm) was first reported for use in biochemistry in 1993, and came into common use for the inhibition serine proteases and of non-protease enzymes such as acetylhydrolases in the mid 1990s.
