产品描述 Description

PAF(C16) is a membrane-derived phospholipid, It is also a platelet activating factor and a ligand for PAF G protein-coupled receptor (PAFR). PAF(C16) is a potent MAPK and MEK/ERK activator. PAF(C16) can induce cell exosmosis in a dose-dependent manner and improve vascular permeability. PAF(C16) inhibits Caspase-dependent cell apoptosis by activating PAFR and has anti-apoptotic effect[1-4].

PAF(C16) (10, 25, 50, and 100 μg/ml; 2 h) inhibits M. smegmatis and M. bovis BCG growth in a dose-dependent manner[2]. PAF(C16) (10 nM; 24 h) can destroy the decreased levels of IL-25 and IL-33 in cells caused by 5α-DHT [5]. 500 nM PAF(C16) increased the numbers of phenotypic Haematopoietic stem/progenitor cell (HSPC) and induced cell cycling of HSPC[6].

PAF(C16) (5 mg/kg; orally administrated every 3 days) significantly inhibited the effect of 5α-DHT on airway hyperreactivity (AHR) [4]. PAF(C16) (0.5-10 ng/kg) given as a bolus into the renal arterial circulation of pentobarbital sodium-anesthetized male Wistar rats caused systemic hypotension and produced a dose-dependent increase in renal blood flow [7].

PAF(C16)是一种膜源磷脂，也是血小板活化因子和PAF G蛋白偶联受体(PAFR)的配体。PAF(C16)是一种有效的MAPK和MEK/ERK激活剂。PAF(C16)能以剂量依赖的方式诱导细胞外渗，改善血管通透性。PAF(C16)通过激活PAFR抑制caspase依赖性细胞凋亡，具有抗凋亡作用[1-4]。

PAF(C16) (10, 25, 50, and 100 μg/ml; 2 h)以剂量依赖的方式抑制耻垢分枝杆菌和牛分枝杆菌的生长[1]。PAF(C16) (10 nM ; 24 h)可破坏5α-DHT引起的细胞IL-25、IL-33水平下降[5]。500 nM PAF(C16)可增加表型造血干细胞/祖细胞(HSPC)的数量，并诱导HSPC的细胞周期[6]。

PAF(C16) (5 mg/kg; orally administrated every 3 days)显著抑制5α-DHT对气道高反应性(AHR)的影响[4]。给麻醉的雄性Wistar大鼠肾动脉循环注射PAF(C16) (0.5-10 ng/kg)可引起全体性低血压，并使肾血流量呈剂量依赖性增加[7]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

BEAS-2B cells

Preparation method

Cells were divided into five groups, including control group, TGF-β1 treated group, TGF-β1 plus 5α-DHT treated group, TGF-β1 plus chicanine (a p38 MAPK and ERK1/2 inhibitor) treated group, TGF-β1 plus 5α-DHT and PAF(C16) treated group. The treated concentration and time of drugs were 1 nM 5α-DHT for 24 h, 50 μM chicanine for 24 h, 10 nM PAF(C16) for 24 h. Chicanine and PAF(C16) were dissolved in 2 % ethanol.

Reaction Conditions

10 nM; 24 h

Applications

PAF(C16) can destroy the decreased levels of IL-25 and IL-33 in cells caused by 5α-DHT.

Animal experiment [1]:

Animal models

Female Wistar rats (220 ± 30 g)

Preparation method

The rats were randomly divided into six groups: control group, ovalbumin(OVA) model group (OVA), vehicle treated group (OVA + vehicle), 0.5 mg/kg 5α-DHT treated group (OVA + 5α-DHT), 15 mg/kg chicanine treated group (OVA + chicanine), 5α-DHT and 5 mg/kg PAF(C16) treated group (OVA +5α-DHT + PAF(C16)). During experiments, rats were orally administrated with vehicle or 5α-DHT or chicanine or 5α-DHT plus PAF(C16) every 3 days.

Dosage form

5 mg/kg; orally administrated every 3 days

Applications

PAF(C16) significantly inhibited the effect of 5α-DHT on airway hyperreactivity (AHR).
