Activating Compound

Activating Compound Comment Organism Structure
diethyl maleate enhanced 3-fold upon treatment with 5 mM H2O2 Homo sapiens
H2O2 increased in concentration-dependent manner, fast but transitory activation, concentrations of H2O2 ranging from 1 to 10 mM, maximal effect at 10 mM, maximum reached within 20 min Homo sapiens
additional information membrane-permeable oxidants more effective to provoke synthesis of platelet-activating factor (PAF), no effect on synthesis of platelet-activating factor (PAF) observed in cells treated with 10 mM 2,2'-azobis(2-amidinopropane) dihydrochloride or with 5 mM hydrophobic cumen hydroperoxide Homo sapiens

Inhibitors

Inhibitors Comment Organism Structure
6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid i.e. Trolox, reduces production of platelet-activating factor (PAF) in H2O2-treated HUVEC cells Homo sapiens
N-acetylcysteine reduces production of platelet-activating factor (PAF) in H2O2-treated HUVEC cells Homo sapiens
pyrrolidinecarbodithioic acid i.e. PDTC, reduces production of platelet-activating factor (PAF) in H2O2-treated HUVEC cells Homo sapiens

additional information
-
 exogenous addition of lyso-platelet-activating factor (PAF) without effect on acetyltransferase activity, block of enzyme activity by a tyrosine kinase inhibitor and a calmodulin antagonist in H2O2-stimulated cells suggests involvement of tyrosine kinase and calcium/calmodulin-dependent protein kinase in regulation of enzyme activity Homo sapiens
