TAS0728 — Datasheet

Biological Activity

TAS0728 is a potent, selective, oral active, irreversible and covalent-binding HER2 inhibitor, binds to HER2 at C805, inhibits its kinase activity, with an IC50 of 13 nM. TAS0728 shows IC50s of 4.9, 8.5, 31, 65, 33, 25, 86 and 36 nM for BMX, HER4, BLK, EGFR, JAK3, SLK, LOK and human HER2, respectively. TAS0728 also inhibits the phosphorylation of HER2, HER3, and downstream effectors, shows no obvious effect on EGFR. Antitumor activity[1].

Published experimental findings depend on the model and assay conditions. They do not guarantee equivalent performance in every application. For laboratory research use only.
