More Info
GDC-0623, a selective inhibitor of MEK, also known as mitogen activated protein kinase kinase (MAPKK), is a key component of the RAS/RAF/MEK/ERK pathway, which is frequently activated in human tumors. Inappropriate activation of the MEK/ERK pathway promotes cell growth in the absence of exogenous growth factors.
G479 is Me-Too version of GDC-0623. Their structures are shown below (side-by-side comparison)

Biological target:
GDC-0623 (RG 7421) is a potent, ATP-uncompetitive inhibitor of MEK1 (Ki=0.13 nM, +ATP), and displays 6-fold weaker potency against HCT116 (KRAS (G13D), EC50=42 nM) versus A375 (BRAFV600E, EC50=7 nM).
In vitro activity:
Compared to the control group, after 7 days of osteogenic induction, ALP staining showed that signals in IL-1β-treated groups were significantly inhibited. However, the ALP signal recovered after GDC0623 treatment (Figure 2(a)). ALP activities were further quantitatively analyzed, showing that ALP activities of osteoblasts in the IL-1β groups were lower than those of the control group. However, ALP activities in osteoblasts significantly recovered after GDC0623 treatment (Figure 2(b)).
