GDC-0879 Usage And Synthesis

Uses

GDC 0879 is a potent B-Raf inhibitor.

Definition

ChEBI: GDC-0879 is a member of the class of pyrazoles that is 1-(2-hydroxyethyl)pyrazole carrying additional 4-pyridyl and 1-(hydroxyimino)indan-5-yl substituents at positions 3 and 4 respectively. It has a role as a B-Raf inhibitor and an antineoplastic agent. It is a member of pyrazoles, a member of pyridines, a member of indanes, a ketoxime and a primary alcohol.

Biological Activity

gdc-0879 is synthsized as a potent and selective b-raf inhibitor. the raf/mitogen-activated protein kinase kinase (mek)/extracellular signal-regulated kinase signaling pathway is reported to be involved in cellular responses, which is relevant to tumorigenesis.

in vitro

gdc-0879 is a b-raf inhibitor against various in vitro and cell-based assays, such as a375 melanoma and colo205 colorectal carcinoma cell lines, both of which are v600e b-raf mutant. when screened against a panel of 140 kinases at its efficaciou dose, gdc-0879 showed expected activity only against c-raf [1].

in vivo

in mice treated by gdc-0879, both cell line-and patient-derived brafv600e tumors exhibited stronger and more sustained pharmacodynamic inhibition (>90% for 8 hours) and improved survival compared with mutant kras-expressing tumors. moreover, it was found that the responsiveness of brafv600e melanoma cells to gdc-0879 could be dramatically altered by pharmacologic and genetic modulation of phosphatidylinositol 3-kinase pathway activity [2].

IC 50

0.13 nm against purified b-raf v600e enzyme; a cellular perk ic50 of 63 nm in the malme-3m cell line

storage

Store at -20°C
