| In vitro study | PMSF can rapidly inhibit the activity of chymotrypsin purified from human pancreas, while it has a weak effect on human trypsin, and can also rapidly inhibit pancreatic cholinesterase in human erythrocytes. PMSF is an inhibitor of specific phosphatidylinositol phospholipase C. A 2 mM PMSF can almost completely inhibit the formation of phosphatidylinositol (PI) activated by Carbachol in longitudinal smooth muscle of guinea pig ileum, however, there was no effect on the pathway of phosphatidylinositol formation from inositol activated by myosin. In contrast, PMSF produced a transient inhibitory effect on both Carbachol and potassium-stimulated muscle contractions. PMSF also inhibited the addition of ethanolamine phosphate to the formation of the Glycosylphosphatidylinositol (GPI) intermediate in Trypanosoma brucei and the acylation of the muscle sugar residue of the GPI intermediate in the blood of Trypanosoma brucei. PMSF can inhibit the addition of ethanolamine phosphate and acylation of muscle sugar in the pre-circulating form of Trypanosoma brucei, but cannot inhibit this process in mammalian HeLa cells. PMSF is the best inhibitor of murine acetylcholinesterase, because the inhibitory effect of 8 times of BSF is 6 times lower than that of PMSF. |
| In vivo study | Intraperitoneal injection of PMSF into Sprague-Dawley rats produced a dose-dependent analgesic effect. PMSF can significantly improve the analgesic effect of β-endorphin (END) in rats. Intraperitoneal injection of PMSF in mice can produce the effect of cannabinoids, which can resist injury, lower body temperature and maintain immobility. Their ED50 is 86 mg/kg respectively, 224 mg/kg and 206 mg/kg. Pretreatment with a low dose of PMSF (30 mg/kg) enhanced the effects of cannabinoids on tail-flick response (antinociceptive effect), spontaneous mobility and mobility by a factor of 5, 10 times and 8 times. Treatment of hens with PMSF 12 hours before PSP provides complete protection against Delayed Neurotoxicity (OPIDN), but treatment with PMSF 4 hours after PSP potentiates neurotoxic effects. At 1 or 10 mg/kg. Pretreatment with PMSF inhibited trio-cresyl phosphate (TOCP)-induced neurofilament (NF) degeneration and prevented organophosphate-induced delayed neuropathy (OPIDN) in hens. By inhibiting fatty acid amide hydrolase activity, PMSF can inhibit the canonical cannabinoid effect of Δ(9)-tetrahydrocannabinol (THC) or cannabinoid (AEA) in ICR mice. |
