C16-PAF (PAF (C16)) 是一种磷脂介质,是血小板活化因子,也是 PAF G 蛋白偶联受体 (PAFR) 的配体。C16-PAF 表现出抗凋亡作用,并通过激活 PAFR 来抑制 caspase 依赖性死亡。C16-PAF 是有效的MAPK和MEK/ERK激活剂。C16-PAF 诱导血管通透性增加。
生物活性 | C16-PAF (PAF (C16)), a phospholipid mediator, is a platelet-activating factor and ligand for PAF G-protein-coupled receptor (PAFR). C16-PAF exhibits anti-apoptotic effect and inhibits caspase-dependent death by activating the PAFR. C16-PAF is a potentMAPKandMEK/ERKactivator. C16-PAF induces increased vascular permeability[1][2][3][4][5]. |

体外研究 (In Vitro) | C16-PAF (PAF (C16); 0.5-1.5 μM; for 24 hours) elicits significant concentration-dependent neuronal loss in PAFR–/–but not PAFR+/+cultures. C16-PAF (1 μM) elicits neuronal death in PAFR–/–cells infected with EGFP alone[1]. C16-PAF (1 μM; for 24 hours) activates caspase 7 but not caspase 3 in PAFR–/–neurons[1]. C16-PAF is synthesized by two distinct pathways; the remodeling pathway and the de novo synthesis pathway. C16-PAF acts by binding to a unique G-protein-coupled seven transmembrane receptor[2][3]. C16-PAF (1-25 μg/ml; 6, 12, 24 h) inhibitsM. smegmatisandM. bovisBCG growth in a time-dependent manner[3].
