Phenylmethanesulfonyl fluoride (PMSF) is an irreversible serine/cysteine protease inhibitor used in protein extraction experiment. It is also a putative inhibitor of phosphatidylinositol-specific phospholipase C, almost completely inhibited carbachol-stimulated inositol incorporation into phosphatidylinositol (PI) of longitudinal smooth muscle of guinea pig ileum, while it had no effect on potassium-stimulated inositol incorporation. PMSF (2 mM) inhibited carbachol-stimulated inositol phosphate accumulation in the presence of Li+ by only 15% - 19%[3]. Mice receiving i.p. injections of PMSF exhibited cannabinoid effects that included antinociception, hypothermia and immobility with ED50 values of 86, 224 and 206 mg/kg, respectively. Spontaneous activity was reduced at doses greater than 100 mg/kg. On the other hand, pretreatment with an inactive dose of PMSF (30 mg/kg) potentiated the effects of anandamide on tail-flick response (antinociception), spontaneous activity and mobility by 5-, 10- and 8-fold, respectively. PMSF did not alter anandamide's hypothermic effects[4]. PMSF inhibits the acylation of the inositol residue of GPI intermediates in bloodstream form T. brucei. PMSF inhihits the formntion of glycolipid C but does not inhibit fatty acid remodeling in vitro. PMSF inhihits GPI acylation and ethanolamine phosphatp addition in procyclic trypanosomes but not in Hela cells[5].
