Chemical Structure

Biological activities

TAK-632 is a potent pan-RAF inhibitor.[1,2] In vitro, TAK-632 exerts inhibition activity on pan-RAF with an IC50 of 2.4 nM. TAK-632 is a slow off-rate inhibitor of both BRAF and CRAF, and demonstrated potent inhibitory activity even at high ATP concentration against BRAF(V600E) and CRAF with IC50s of 3.3 and 5.0 nM in a biochemical assay,respectively. In vivo, in both A375 (BRAFV600E) and HMVII (NRASQ61K) xenograft models in rats, TAK-632 demonstrates regressive antitumor efficacy.[1]Administration of TAK-632 at doses of 4??5 mg/kg in a melanoma A375 (BRAFV600E) xenograft model in rats potently inhibits the MAPK cascade in tumor cells. Furthermore, administration of TAK-632 (4??5 mg/kg) demonstrates regressive antitumor efficacy without body weight changes. Moreover, TAK-632 induces regression in HMVII (NRASQ61K) tumors and restores body weight loss derived from HMVII tumor-induced cachexia.[2]

Protocols

In vitro, AS-604850 is dissolved in DMSO.[1]
