Eeyarestatin I 是一种有效的内质网相关蛋白降解 (ERAD) 抑制剂,是一种有效的蛋白易位抑制剂。Eeyarestatin I 抑制Sec61转位子。Eeyarestatin I 靶向与 p97 相关的去泛素化过程 (PAD),并抑制依赖于 atx3 的去泛素化。Eeyarestatin I 在蛋白酶体降解前一步进行干扰。Eeyarestatin I 可防止 Sec61 蛋白易位。Eeyarestatin I 通过促凋亡蛋白 NOXA 诱导细胞死亡,并具有抗癌作用。
生物活性 | Eeyarestatin I, a potentendoplasmic reticulum-associated protein degradation (ERAD)inhibitor, is a potent protein translocation inhibitor. Eeyarestatin I inhibitsSec61translocon. Eeyarestatin I targets the p97-associated deubiquitinating process (PAD) and inhibits atx3-dependent deubiquitination. Eeyarestatin I interferes at a step prior to proteasomal degradation. Eeyarestatin I induces cell death via the proapoptotic protein NOXA and has anticancer effects[1][2][3][4][5]. |

体外研究 (In Vitro) | Eeyarestatin I (2.5-40 μM; 48 hours; A549 and H358 cells) treatment causes a dose-dependent cell death of both A549 and H358 cells[1]. Eeyarestatin I (2.5-40 μM; 48 hours; A549 and H358 cells) treatment increases endoplasmic reticulum (ER) stress markers including Bip and CHOP as low as 20 μM. Eeyarestatin I treatment shows a dose dependent ubiquitination of key proteins including PERK and IRE1α[1]. Eeyarestatin I (20 μM; 48 hours; A549 and H358 cells) treatment induces cell migration and cell invasion[1]. Eeyarestatin 1 prevents the transfer of nascent proteins from the membrane-targeting complex to the ER translocation machinery, most probably by inactivating the Sec61 complex[2].
