gdc-0623

GDC-0623 (RG 7421) 是一种 ATP 竞争性的MEK1抑制剂，Ki 值为 0.13 nM。它对 A375 细胞中 BRAFV600E 的 EC50值为 7 nM，而对 HCT116 细胞中 KRAS (G13D)的 EC50值为 42 nM。

G-479 is an potent MEK inhibitor. Structurally, G-479 is an analogue of GDC-0623 (or so-call Me-Too drug). G-479 with polarity distributed throughout the molecule was shown improved bioactivity over GDC-0623 in many aspects.
