Description

PMSF is an irreversible serine/cysteine protease inhibitor.

In Vitro

PMSF (2 mM) inhibits carbachol-stimulated inositol phosphate accumulation in the presence of Li+ by only 15%-19%. PMSF inhibition of phosphoinositide turnover is due to one or more steps following phosphoinositide breakdown[1]. 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[2].

In Vivo

PMSF (0.1 mL/10 g b.wt, i.p.) produces antinociception as indicated by the dose-responsive increase in % MPE in the tail-flick latency evaluation, but fails to produce a clear dose-responsive inhibition of locomotion. Mice receiving i.p. injections of PMSF exhibit cannabinoid effects that includes antinociception, hypothermia and immobility with ED50 values of 86, 224 and 206 mg/kg, respectively. PMSF (30 mg/kg) pretreatment potentiates the effects of anandamide on tail-flick response (antinociception), spontaneous activity and mobility by 5-, 10- and 8-fold, respectively[3].

Animal Administration
[3]

Male ICR mice weighing 18 to 25 g are used in the assay. PMSF is dissolved in sesame oil and administered i.p. at a volume of 0.1 mL/10 g b.wt. PMSF is always administered 10 min before i.v. anandamide or vehicle injections. Mice are acclimated to the evaluation room overnight without interruption of food or water. After i.v. anandamide or vehicle administration each animal is evaluated as follows: tail-flick latency (antinociception) response at 5 min and spontaneous (locomotor) activity at 5 to 15 min; or core (rectal) temperature at 5 min and ring-immobility (catalepsy) at 5 to 10 min.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
