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. 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. PD 169316 inhibits apoptosis of neuronal and non-neuronal cells deprived of specific trophic factors such as potassium or nerve growth factor.
용도
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
일반 설명
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.
