| Hazard Information | Back Directory | [Description]
p38 is a member of the mitogen-activated protein kinase (MAPK) superfamily of enzymes that play an important role in signal transduction. PD 169316 is a selective inhibitor of p38 MAPK.1 It inhibits p38 MAPK with an IC50 of 89 nM, whereas the IC50s are >100-fold higher for extracellular signal-regulated kinase (ERK) and >1,000-fold higher for protein kinase A (PKA) and PKCα.1 PD 169316 inhibits apoptosis of neuronal and non-neuronal cells deprived of specific trophic factors such as potassium or nerve growth factor.2,3 | [Uses]
PD 169316 is a highly selective, potent inhibitor of p38 MAP kinase. PD 169316 inhibits transforming growth factor β-induced Smad signaling in human ovarian cancer cells. PD 169316 acts as an an endogenous suppressor of apoptosis by mimicking CD9, a membrane tetraspanin. Studies show that PD 169316 reduces myocardial ischemia/reperfusion induced voltage-dependent anion channel(VDAC) phosphorylation | [Definition]
ChEBI: 4-[4-(4-fluorophenyl)-2-(4-nitrophenyl)-1H-imidazol-5-yl]pyridine is a member of imidazoles. | [General Description]
PD 169316 is a pyridinyl imidazole compound. It is a potential inhibitor of p38 mitogen-activated protein kinases. It also inhibits signalling transforming growth factor β (TGFβ), particularly in human ovarian cancer cells. | [Biological Activity]
Potent, cell permeable and selective inhibitor of p38 (SAPK2a). | [Biochem/physiol Actions]
Potent, cell-permeable and selective p38 MAP kinase inhibitor (IC50 = 89 nM). | [in vitro]
it was reported that pretreatment of caov3 cells with 10 m pd169316 caused a significant decrease in smad2 and smad3 phosphorylation which was mediated by tgf-β. the inhibitory effect of pd 169316 was proved to act in a dose-dependent manner. study also demonstrated that pd169316 at 5 m or higher dose directly suppressed tgf-β signaling activity. [1] | [in vivo]
based on an amyloid β (aβ) rat model of alzheimer's disease, the effect of pd 169316 on apoptosis induced by amyloid beta was examined. it was demonstrated that caspase-3 and bax/bcl-2 ratio, two marks of apoptosis, were significantly decreased in the rats pre-treated with pd169316 intracerebroventricularly. this study suggested the potential neuroprotective role of pd 169316 against the neuronal toxicity induced by aβ.
