產(chǎn)品描述
Z-AAD-CH2Cl(Z-AAD-CMK)是一種細(xì)胞滲透性的和不可逆的顆粒酶B抑制劑[1].
顆粒酶B是一種細(xì)胞凋亡誘導(dǎo)因子,表達(dá)于自然殺傷(NK)細(xì)胞以及細(xì)胞毒性淋巴細(xì)胞(CTLs)顆粒和細(xì)胞毒性T細(xì)胞中,在誘導(dǎo)炎癥和細(xì)胞外基質(zhì)重塑中起著重要作用[1].
Z-AAD-CH2Cl(Z-AAD-CMK)是一種細(xì)胞滲透性的和不可逆的顆粒酶B抑制劑.在表達(dá)NK細(xì)胞表面抗原的人C-28/12軟骨細(xì)胞中,Z-AAD-CMK呈劑量依賴性地抑制軟骨細(xì)胞對(duì)K562細(xì)胞的細(xì)胞毒作用,該作用依賴于顆粒酶B[1].在口腔鱗狀細(xì)胞癌細(xì)胞系OSC-3中,與對(duì)照組相比,Z-AAD-CMK減少白介素-2激活淋巴細(xì)胞(LAK細(xì)胞)增強(qiáng)的caspase-3活性(約70%),并抑制約20%的 DNA片段.與對(duì)照組相比,Z-AAD-CMK也抑制LAK細(xì)胞誘導(dǎo)的活性氧中間體(ROI)增加(約50%)[2].在Tc1細(xì)胞中,Z-AAD-CMK抑制細(xì)胞凋亡[3].
