CAS No. : 16561-29-8
MCE 國際站:Phorbol 12-myristate 13-acetate
產(chǎn)品活性:Phorbol 12-myristate 13-acetate (PMA) 是一種佛波酯,,是蛋白激酶 C (PKC) 和 SphK 的激活劑。Phorbol 12-myristate 13-acetate 是 NF-κB 激活劑,。Phorbol 12-myristate 13-acetate 可誘導(dǎo) THP-1 細(xì)胞分化 (已經(jīng)經(jīng)過 MCE 專業(yè)的生物實(shí)驗(yàn)驗(yàn)證),。
研究領(lǐng)域:Epigenetics | TGF-beta/Smad | Immunology/Inflammation | NF-κB
作用靶點(diǎn):PKC | SphK | NF-κB
In Vitro: PMA (100, 200 ng/mL; 1-5 days) induce THP-1 cells to differentiate into macrophage-like cells (THP-1 macrophages), characterized by changes in morphology (adherent macrophage-like phenotype), and increases cell surface expression of CD11b.
PMA (20 ng/mL, 36 h) inhibits endothelial cell migration through activating the PKC-δ/Syk/NF-κB-mediated up-regulation of Thy-1.
In Vivo: Phorbol 12-myristate 13-acetate (PMA) can be used to create models of ear edema and paw edema.
1. Induction of oedema at ear
Background
PMA induces a pronounced inflammatory response mediated by protein kinase C (PKC), specifically activating PLA2 to trigger inflammation.
Specific Modeling Methods
Mice: Swiss mouse ? Female ? 25-30 g
Administration: Topically applied in one ear ? 100 μg/mL in 20 μL (2 μg/ear) vehicle ? single dose
Modeling Indicators
Appearance monitoring: The thickness difference between the left and right ears increases significantly.
Indicator changes: Increased vascular permeability.
Correlated Product(s): /
Opposite Product(s): Hydroxyachillin; Indomethacin (HY-14397)
2. Induction of oedema at feet
Background
PMA induces a pronounced inflammatory response mediated by protein kinase C (PKC), specifically activating PLA2 to trigger inflammation.
Specific Modeling Methods
Rat: Wistar ? male ? adult with weight of 200-220 g
Mice: Swiss albino ? male ? 25-30 g
Administration: Topically applied in one ear ? 2.5 μg in 20 μL vehicle ? single dose
Note
Administration should be conducted 4 h before mouse were killed.
Modeling Indicators
Appearance monitoring: The quality difference between the left and right ears increases significantly.
Indicator changes: Stimulate macrophages to produce superoxide anions.
