生物化工:CDK 抑制劑常見問題列表
生物活性
SU9516是一種3位取代的吲哚酮類CDK抑制劑,對(duì)CDK2,CDK1,和CDK4的IC50分別為22 nM,40 nM,和200 nM。體外研究
SU9516 decreases cdk2-specific phosphorylation of the retinoblastoma protein pRB, increases caspase-3 activation, and alters cell cycle in RKO and SW480 cells. SU9516 also inhibits the cell proliferation, and induces cell apoptosis in both cell lines. SU9516 kills leukemic cells through inhibition of RNA Pol II CTD phosphorylation, oxidative damage and transcriptional down-regulation of Mcl-1. In human T-cell leukemia Jurkat cells, SU9516 significantly enhances sensitivity to methotrexate. In addition, SU9516 also suppresses Aurora-A centrosomal localization and consequent centrosome amplification.靶點(diǎn)

體外研究
在RKO和SW480細(xì)胞中,SU9516減小cdk2特定的視網(wǎng)膜細(xì)胞瘤蛋白pRB磷酸化作用, 增加胱天蛋白酶-3的活化作用,并改變細(xì)胞周期。SU9516也會(huì)抑制細(xì)胞系中細(xì)胞增殖,并誘導(dǎo)細(xì)胞凋亡。 SU9516通過抑制RNA Pol II CTD磷酸化,氧化性損傷以及Mcl-1的轉(zhuǎn)錄下調(diào)從而殺死白血病細(xì)胞。在人T細(xì)胞白血病Jurkat細(xì)胞,SU9516顯著增強(qiáng)對(duì)甲氨蝶呤的敏感性。此外,SU9516也會(huì)抑制Aurora-A中心體定位和隨后的中心體擴(kuò)增。
