TAK-285 is a potent, selective, ATP-competitive and orally active HER2 and EGFR(HER1) inhibitor with IC₅₀ of 17 nM and 23 nM, respectively. TAK-285 is >10-fold selectivity for HER1/2 than HER4, and less potent to MEK1/5, c-Met, Aurora B, Lck, CSK etc. TAK-285 has effective antitumor activity^[1]. TAK-285 can cross the blood-brain barrier (BBB)^[2].

TAK-285 (Compound 34e) shows significant growth inhibitory activity against BT-474 cells (HER2-overexpressing human breast cancer cell line) with GI₅₀ of 17 nM^[1]. TAK-285 (Compound 34e) exhibits HER4 inhibitory activity with an IC₅₀ value of 260 nM. TAK-285 also inhibits MEK1, MEK5, c-Met, Aurora B, Lck, CSK and Lyn B with IC₅₀s of 1100 nM, 5700 nM, 4200 nM, 1700 nM, 2400 nM, 4700 nM and 5200 nM, respectively^[1].

TAK-285 (Compound 34e; 50-100 mg/kg; oral administration; twice daily; for 14 days; female BALB/cAJcl mice) treatment exhibits dose-dependent tumor growth inhibition (tumor/control ratio [T/C]): 44% and 11% at 50 and 100 mg/kg, respectively) without significant body weight loss in mice^[1].
