Irbinitinib ARRY-380 ONT-380 Tucatinib 937263-43-9
Biological Activity
Tucatinib, also known as Irbinitinib and ONT-380, is an orally bioavailable inhibitor of the human epidermal growth factor receptor tyrosine kinase ErbB-2 (HER2). Irbinitinib selectively binds to and inhibits the phosphorylation of ErbB-2, which may prevent the activation of ErbB-2 signal transduction pathways, resulting in growth inhibition and death of ErbB-2-expressing tumor cells.
