PMSF yog ib qho irreversible serine / cysteine protease inhibitor feem ntau siv rau hauv kev npaj ntawm cell lysates.
Kev tshawb fawb hauv vitro: PMSF (2 mM) inhibited carbachol-stimulated inositol phosphate tsub zuj zuj los ntawm tsuas yog 15% -19% nyob rau hauv lub xub ntiag ntawm Li +.Qhov inhibition ntawm phosphoinositide turnover los ntawm PMSF yog vim ib lossis ntau cov kauj ruam tom qab kev tawg ntawm phosphoinositide [1].PMSF inhibits acylation ntawm inositol residues ntawm GPI intermediates hauv cov hlab ntsha ntawm T. brucei.PMSF inhibits glycolipid C tsim tab sis tsis fatty acid hloov kho hauv vitro.PMSF inhibits ntxiv ntawm GPI acylation thiab ethanolamine phosphatase hauv procyclic trypanosomes, tab sis tsis nyob hauv Hela hlwb [2].
Hauv vivo cov kev tshawb fawb: PMSF (0.1 mL / 10 g b.wt, ip) tsim cov tshuaj tiv thaiv kab mob, raws li qhia los ntawm kev siv tshuaj ntau ntxiv hauv % MPE hauv kev ntsuas tus tw-flick latency, tab sis ua tsis tiav los ua kom pom tseeb koob tshuaj tiv thaiv lub cev muaj zog.Cov nas uas tau txais kev txhaj tshuaj intraperitoneal ntawm PMSF tau nthuav tawm cov teebmeem cannabinoid nrog rau kev tiv thaiv kev tiv thaiv, hypothermia thiab immobility nrog ED50 qhov tseem ceeb ntawm 86, 224 thiab 206 mg / kg, feem.PMSF (30 mg / kg) pretreatment txhim kho cov teebmeem ntawm anandamide ntawm tail-flick cov lus teb (antinociception), locomotor kev ua ub no thiab kev txav mus los ntawm 5-fold, 10-fold thiab 8-fold, feem [3].
Kev sim tsiaj: Txiv neej ICR nas uas hnyav 18 txog 25 g tau siv rau hauv qhov kev xeem.PMSF tau yaj nyob rau hauv cov noob hnav roj thiab muab tshuaj intraperitoneally hauv ib ntim ntawm 0.1 mL / 10 g b.wt.Ib txwm tswj hwm PMSF 10 feeb ua ntej txhaj tshuaj anandamide lossis txhaj tshuaj tsheb.Cov nas tau nkag mus rau hauv chav ntsuas ntsuas ib hmos yam tsis muaj kev cuam tshuam ntawm zaub mov lossis dej.Tom qab txhaj tshuaj anandamide lossis kev tswj xyuas lub tsheb, txhua tus tsiaj tau raug soj ntsuam raws li hauv qab no: 5 feeb rau cov lus teb tail-flick latency (antinociceptive) thiab 5 mus rau 15 feeb rau kev ua haujlwm (lub cev muaj zog);los yog 5 feeb rau qhov kub thiab txias (qhov quav) thiab lub nplhaib Immobilization (catalepsy) rau 5 mus rau 10 feeb.
