Biological Activity
Description
PMSF (Phenylmethylsulfonyl Fluoride, Benzylsulfonyl fluoride) is an irreversible serine/cysteine protease inhibitor.
Targets
cysteine protease
chymotrypsin
In vitro
Although human trypsin is less susceptible to inhibition by PMSF, this compound rapidly inactivates purified chymotrypsin from human pancreas. It also rapidly inhibits acetylcholinesterase from human red cells. As an inhibitor of phosphatidylinositol-specific phospholipase C, treatment with this chemical at 2 mM almost completely inhibits carbachol-stimulated inositol incorporation into phosphatidylinositol (PI) of longitudinal smooth muscle of guinea pig ileum, while it has no effect on potassium-stimulated inositol incorporation. In contrast to its specific inhibition of carbachol-stimulated phosphoinositide turnover, this agent produces a transient inhibition of contraction by both carbachol and potassium. It has been shown to inhibit the addition of ethanolamine phosphate to glycosylphosphatidylinositol (GPI) intermediates in Trypanosoma brucei. This inhibitor also inhibits the acylation of the inositol residue of GPI intermediates in bloodstream form T. brucei. It inhibits ethanolamine phosphate addition and inositol acylation for procyclic forms of T. brucei but not for mammalian HeLa cells. This compound is the more reactive inactivator of mouse acetylcholinesterase (AChE), as the 8-fold higher BSF concentration is necessary to achieve even a 6-fold slower inactivation than that using PMSF.
In Vivo
Intraperitoneal injection of PMSF produces dose-dependent analgesia in Sprague-Dawley rats. This compound significantly enhances the analgesic effect of beta-endorphin (END) in rats. Mice receiving i.p. injections of this chemical exhibit cannabinoid effects that include antinociception, hypothermia and immobility with ED50 of 86 mg/kg, 224 mg/kg and 206 mg/kg, respectively. Pretreatment with an inactive dose of this compound (30 mg/kg) enhances the effects of anandamide on tail-flick response (antinociception), spontaneous activity and mobility by 5-, 10- and 8-fold, respectively. Administration of this chemical 12 hours prior to PSP causes complete protection in organophosphorus ester-induced delayed neuropathy (OPIDN) in hens, but it administered 4 hours after PSP potentiates its neurotoxic effects. Pretreatment with this compound (30 mg/kg, i.p.) prior to an injection of 1 or 10 mg/kg 3H-anandamide results 5 minutes later in enhanced brain levels of anandamide compared to those obtained with 3H-anandamide plus vehicle injection. Pretreatment with it inhibits tri-ortho-cresyl phosphate (TOCP)-induced neurofilament (NF) degradation, and protects hens against the development of organophosphate-induced delayed neuropathy (OPIDN). Administration of this chemical enhances the characteristic cannabimimetic effects of Δ(9)-tetrahydrocannabinol (THC) or anandamide (AEA) in ICR mice, by inhibiting the enzyme fatty acid amide hydrolase.
Administered i.p. 10 minutes before i.v. anandamide injection
