Synonyms:
PMSF, Phenylmethanesulphonyl fluoride, Phenylmethylsulphonyl fluoride, α-Toluenesulphonyl fluoride
Phenylmethylsulfonyl fluoride is an irreversible inhibitor of serine proteases - inhibits trypsin, chymotrypsin and protease. Inhibits mammalian acetyl cholinesterase, but not those from fish sources.
- Presentation: White to off white needle crystals
- Causes sulfonylation of the active-site serine residue
- A less toxic substitute for the extremely toxic diisopropylfluorophosphate
Phenylmethylsulfonyl fluoride inhibits serine proteases such as trypsin and chymotrypsin. Also inhibits cysteine proteases (reversible by reduced thiols) and mammalian acetylcholinesterase.
Administration of PMSF produces analgesia unrelated to its anticholinesterase effect, and prolongs the analagesic effect of centrally administered β-endorphin.
