产品描述:
Phorbol 12-myristate 13-acetate(佛波肉荳蔻醋酸),简称PMA,又名TPA,一种广泛用于体内外实验的佛波酯类PKC激活剂。PMA可抑制Fas诱导的细胞凋亡,同时又可诱导HL-60细胞的凋亡发生。PMA是一种强效的肿瘤促进剂,能够诱导小鼠皮肤瘤生成。常常与离子霉素Ionomycin(货号:MZ2151-1MG)联合刺激多种免疫细胞,以产生细胞因子。同时也与蛋白转运抑制剂如布雷非德菌素A(Brefeldin A,货号:MZ2103-200UL),莫能霉素(Monensin,货号:MZ2102-100MG)联合使用,抑制细胞因子外分泌,保留在细胞内以准确分析细胞因子表达水平。
4α-Phorbol 12-myristate 13-acetate(4α-佛波肉荳蔻醋酸),简称4α-PMA,又名4α-TPA,CAS NO:63597-44-4,是PMA的结构类似物,不能激活PKC活性,通常用作PMA靶向PKC信号通路研究的阴性对照。4α-PMA还是一种相对有效的TRPV4通道激活剂,是一种实用的工具,通过与相似化合物-4α-PDD的比较来进行结构活性研究。4α-PDD对TRPV4的亲和性比4α-PMA高50倍。4α-PMA不是肿瘤促进剂。

two-pore domain K+ channel, TASK-1, inducing repolarization abnormalities in
cardiac ventricular myocytes. J Biol Chem. 2004 Aug 6;279(32): 33154- 60.

体外研究:
细胞类型(Cell type):CHO cells expressing TASK-1
药物配制(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.
实验方法(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.

体外研究:
细胞类型(Cell type):Human nasal epithelial cells (HNE)
药物配制(Preparation):4α-PMA and PMA were dissolved in DMSO first before
being diluted to the desired concentrations in M199.
实验方法(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
