Osimertinib Mesylate (AZD-9291 mesylate) is the mesylate salt form of osimertinib, a third-generation, orally bioavailable, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). Chemically designated as N-(2-{[2-(dimethylamino)ethyl]methylamino}-4-methoxy-5-{[4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl]amino}phenyl)prop-2-enamide methanesulfonate, Osimertinib Mesylate features a quinazoline core with an acrylamide warhead that forms a covalent bond with the C797 residue in the ATP-binding pocket of the EGFR kinase domain, enabling prolonged target inhibition.
