Irbinitinib Usage And Synthesis
Description Irbinitinib is also known as ARRY-380 or Tucatinib. ARRY-380 is an orally inhibitor of human epidermal growth factor receptor tyrosine kinase ErbB-2 (also called HER2) with potential antineoplastic activity. It 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. ErbB-2 is overexpressed in a variety of cancers and plays an important role in cellular proliferation and differentiation. Therefore, ARRY-380 may be an alternative treatmentmethod for the treatment of HER2+ cancers.
Uses N6-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)-N4-[3-methyl-4-([1,2,4]triazolo[1,5-a]pyridin-7-yloxy)phenyl]-4,6-quinazolinediamine is a novel?diarylamine ErbB inhibitor.
