产品描述 | Cobimetinib (GDC-0973, RG7420)是一种有效的高选择性MEK1抑制剂,IC50 为 4.2 nM,且对其他很多丝氨酸-苏氨酸和酪氨酸激酶没有显著抑制作用。Cobimetinib 可诱导凋亡。Phase 3。 | ||

靶点 |
|
||
体外研究 | Cobimetinib对一组广泛类型的肿瘤细胞的生长表现出强烈的抑制活性,特别是对BRAF或KRAS突变型癌细胞系。结合GDC-0941,GDC-0973在888MEL和A2058细胞中导致生存能力降低,通路抑制,以及细胞凋亡增加。[1]
|
||
体内研究 | 在负荷BRAFV600E和KRAS突变型肿瘤的小鼠体内,Cobimetinib (10 mg/kg, p.o.)产生抗肿瘤作用,结合GDC-0973和GDC-0941能够提高疗效。[1] 在负荷耐药的A375异种移植物小鼠体内,GDC-0973与GDC-0941结合诱导己糖激酶II,c-RAF,Ksr 和p-MEK蛋白质的水平减少。[2] |
