Apexbio Technology LLC OSI-420 free base 183321-86-0 5mg
OSI-420 free base (CAS 183321-86-0) is an active metabolite of erlotinib (OSI-774) exhibiting inhibitory activity against epidermal growth factor receptor (EGFR) tyrosine kinase Mechanistically OSI-420 inhibits EGFR by binding competitively to the ATP-binding site within the intracellular kinase domain thus preventing receptor autophosphorylation and subsequent signaling Additionally through EGFR inhibition it can trigger apoptosis via mitochondrial disruption including loss of mitochondrial membrane potential and cytochrome c release OSI-420 is utilized in biomedical research for studying EGFR-related signaling pathways and apoptosis mechanisms
