MCB-613
目录号 : KM12034 CAS No. : 1162656-22-5 纯度 : 98%

MCB-613 是一种有效的类固醇受体共激活因子 (SRC) 小分子“刺激物” (SMS),超刺激 SRCs 的转录活性。 MCB-613 增加了 SRC 与其他共激活因子的相互作用,并显着诱导 ER 应激与活性氧 (ROS) 的产生相结合。 MCB-613 是一种 SMS,通过过度刺激 SRC 致癌程序,靶向癌基因用作抗癌药物。

生物活性

MCB-613 is a potent Steroid receptor coactivator SRC small molecule ‘stimulator’ (SMS), super-stimulates SRCs’ transcriptional activity. MCB-613 increases SRCs’ interactions with other coactivators and markedly induces ER stress coupled to the generation of reactive oxygen species (ROS). MCB-613 is a SMS that target oncogenes can be exploited as anti-cancer agents by over-stimulating the SRC oncogenic program.

体外研究

MCB-613 (6-8 μM; 24 hours) activates endogenous MMP13 mRNA expression in MDA-MB-231 cells.
MCB-613 (2-10 μM; 4 hours) leads to proteasome dysfunction and ER stress, the induction of the markers for unfolded protein response (UPR), including the phosphorylation of eIF2α and IRE1α as well as the induction of ATF4 protein expression.
MCB-613 (0-7 μM; 4 hours) affects SRC-3 KO and WT HeLa cell viability, SRC-3 WT HeLa cell is more affected by MCB-613 compared with KO cells.
