| 产品描述: | HSP(HSP90) 调节剂;HSP(HSP90) Modulators;HA15 是一种特异靶向 HSPA5 (Heat shock 70kDa protein 5) 也可称为 BiP (Immunoglobulin heavy-chain-binding protein) 或 Grp78 (glucose-regulated protein 78) 的小分子。在所检测的黑色素瘤细胞中具有抗肿瘤活性,包括从病人中分离得到的细胞和对BRAF抑制剂具有耐药性的细胞。;InformationHA15 HA15 is a molecule that targets specifically HSPA5 (Heat shock 70kDa protein 5) also known as BiP (Immunoglobulin heavy-chain-binding protein) or Grp78 (glucose-regulated protein 78) . HA15 displays anti-cancerous activity on all melanoma cells tested, including cells isolated from patients and cells that developed resistance to BRAF inhibitors.TargetsBiP/GRP78/HSPA5In vitroHA15 induces ER stress leading to cancer cell death in vitro and overcomes BRAF inhibitor resistance in melanoma cells.In vivoHA15 induces ER stress leading to cancer cell death and exhibits strong efficacy in xenograft mouse models with melanoma cells either sensitive or resistant to BRAF inhibitors. |
