描述:
PMA (Phorbol-12-Myristate-13-Acetate) is a diester of phorbol and is a tumor promoting compound extracted from croton oil. It is a reversible, highly potent protein kinase C (PKC) activator in vitro and in vivo at nM concentrations. PMA’s effects on PKC are attributed to its similarity to diacylgylerol, a natural activator of PKC. PMA activates Ca2+-ATPase and potentiates forskolin-induced cAMP formation. It has been shown to inhibit apoptosis induced by the Fas antigen, but PMA induces apoptosis in HL-60 promyelocytic leukemia cells.
PMA(同義名:TPA)是一種廣泛用于體內(nèi)外實(shí)驗(yàn)的佛波酯(phorbol ester) PKC激活劑。PMA結(jié)合PKC(Ki =2.6 nM)并激活其功能,在細(xì)胞和組織中都呈現(xiàn)出極其廣的抑制譜。PMA可以抑制Fas誘導(dǎo)的細(xì)胞凋亡,但又可以誘導(dǎo)HL-60細(xì)胞的凋亡。PMA是一種高效的腫瘤促進(jìn)劑,可以促進(jìn)小鼠皮膚瘤的形成。盡管PMA毒性較強(qiáng),但是在人體內(nèi)仍顯示出抗白血病和抗中性白細(xì)胞減少的活性。
應(yīng)用:A reversible and highly potent protein kinase C (PKC) activator
