TAK-285

TAK-285 is a dual inhibitor of EGFR and HER2 (IC50s = 23 and 17 nM, respectively). It is selective for EGFR and HER2 over a panel of 36 kinases (IC50s = 250->10,000 nM). TAK-285 inhibits the proliferation of BT474 breast cancer cells (GI50 = 17 nM) as well as induces tumor regression in a 4-1st gastric adenocarcinoma rat xenograft model when administered at doses of 25 and 50 mg/kg.Formal Name: N-[2-[4-[[3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl]amino]-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethyl]-3-hydroxy-3-methyl-butanamide.
