産品描述:

Phorbol 12-myristate 13-acetate(佛波肉荳蔻醋酸),簡稱PMA,又(yòu)名TPA,一(yī)種廣泛用于體内外實驗的佛波酯類PKC激活劑。PMA可抑制Fas誘導的細胞凋亡,同時又(yòu)可誘導HL-60細胞的凋亡發生(shēng)。PMA是一(yī)種強效的腫瘤促進劑,能(néng)夠誘導小(xiǎo)鼠皮膚瘤生(shēng)成。常常與離子黴素Ionomycin(貨号:MZ2151-1MG)聯合刺激多(duō)種免疫細胞,以産生(shēng)細胞因子。同時也與蛋白(bái)轉運抑制劑如布雷非德菌素A(Brefeldin A,貨号:MZ2103-200UL),莫能(néng)黴素(Monensin,貨号:MZ2102-100MG)聯合使用,抑制細胞因子外分泌,保留在細胞内以準确分析細胞因子表達水(shuǐ)平。

4α-Phorbol 12-myristate 13-acetate(4α-佛波肉荳蔻醋酸),簡稱4α-PMA,又(yòu)名4α-TPA,CAS NO:63597-44-4,是PMA的結構類似物(wù),不能(néng)激活PKC活性,通(tōng)常用作PMA靶向PKC信号通(tōng)路(lù)研究的陰性對照(zhào)。4α-PMA還(hái)是一(yī)種相(xiàng)對有效的TRPV4通(tōng)道激活劑,是一(yī)種實用的工(gōng)具,通(tōng)過與相(xiàng)似化合物(wù)-4α-PDD的比較來進行結構活性研究。4α-PDD對TRPV4的親和性比4α-PMA高(gāo)50倍。4α-PMA不是腫瘤促進劑。

文獻1,Besana A et al. Activation of protein kinase C epsilon inhibits the two-pore domain K+ channel, TASK-1, inducing repolarization abnormalities in cardiac ventricular myocytes. J Biol Chem. 2004 Aug 6;279(32): 33154- 60. Epub 2004 Jun 7. PMID: 15184378

體外研究:

細胞類型(Cell type):CHO cells expressing TASK-1

藥物(wù)配制(Preparation):PMA and negative control4α-PMAwere prepared in Me2SO and then diluted in Tyrode's. The final Me2SO concentration did not exceed 0.1%, and the same concentration was present in the control solution.

實驗方法(Assay):To determine whether activation of PKC alone was sufficient to reduce TASK-1 current, we treated CHO cells expressing TASK-1 with a nonspecific activator of PKC, PMA (100 nM). PMA significantly inhibited TASK-1 current in a manner that was similar to the effect of C-PAF. The specificity of the PMA effect was verified by exposing cells to an inactive PMA analogue, 4α-phorbol 12-myristate 13-acetate (αPMA; 100 nM). αPMA had no detectable effect on TASK-1 current expressed in CHO cells.

體外研究:

細胞類型(Cell type):Human nasal epithelial cells (HNE)

藥物(wù)配制(Preparation):4α-PMA and PMA were dissolved in DMSO first before being diluted to the desired concentrations in M199.

實驗方法(Assay):HNE were maintained at 32℃and CBF profiles were established to test the effects of PKC activation or PKC inhibition (1 nM PMA or 4α-PMA) , or with different combinations of inhibitors
