(GDC-0973, RG7420)是一种有效的高选择性MEK1抑制剂,IC50 为 4.2 nM。其对MEK1的选择性比对MEK2高100倍以上,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。
Cobimetinib是丝裂原活化蛋白激酶激酶(MEK)选择性抑制剂,其IC50值为0.9 nM。
MEK是一种激酶,选择性磷酸化丝氨酸/苏氨酸和酪氨酸残基,并参与丝裂原活化蛋白激酶(MAPK)信号转导通路,从而调控细胞增殖、存活、分化、移动和血管生成。
在同时携带KRAS G13D和B-RAF G464V突变的MDA-MB-231T乳腺癌细胞中,Cobimetinib抑制MEK,其IC50值为0.2 nM。在药代动力学-药效学(PK-PD)模型中, Cobimetinib在肿瘤内的停留时间比在血浆中更长,显示出持续的持续的肿瘤药效学应答。
在WM-266-4异种移植小鼠中,Cobimetinib可以减少肿瘤中的pERK,其IC50值分别为0.78 mM(WM-266-4)和0.52 mM。此外,Cobimetinib(3.89 mM)增加WM-266-4小鼠的IC50值。在A375异种移植物小鼠中,Cobimetinib(0.3 ~ 30 mg/kg)呈剂量依赖性地抑制肿瘤。目前,Cobimetinib作为一种潜在的抗肿瘤剂,正处于I期临床试验。
Information
Cobimetinib (GDC-0973, RG7420) is a potent and highly selectiveMEK1inhibitor with IC50 of 4.2 nM, showing more than 100-fold selectively for MEK1 over MEK2 and showed no significant inhibition when tested against a panel of more than 100 of serine-threoni
In vitro
Cobimetinib shows strong activity on cell growth inhibtion in a broad panel of tumor types, particularly in BRAF or KRAS mutant cancer cell lines. In combination with GDC-0941, GDC-0973 results in reduced viability, pathway inhibition, and increased apoptosis in 888MEL and A2058 cells. Coadministration of GDC-0973 and vemurafenib significantly increases decreased levels of GLUT-1 on the cellular membrane across all BRAFV600E lines.
In vivo
In mice bearing BRAFV600E and KRAS mutant tumors, Cobimetinib (10 mg/kg, p.o.) produces antitumor efficacy, and the combination of GDC-0973 and GDC-0941 show improved efficacy. In mice bearing drug-resistant A375 xenografts, combination of GDC-0973 and GDC-0941 induces decreased levels of hexokinase II, c-RAF, Ksr and p-MEK protein.
