Almonertinib (HS-10296) mesylate is an orally available, irreversible, third-generation EGFR tyrosine kinase inhibitor with high selectivity for EGFR-sensitizing and T790M resistance mutations. Almonertinib mesylate shows great inhibitory activity against T790M, T790M/L858R and T790M/Del19 ( IC 50 : 0.37, 0.29 and 0.21 nM, respectively), and is less effective against wild type (3.39 nM). Almonertinib mesylate is used for the research of the non-small cell lung cancer. In Vitro HS-10296 mesylate is an orally available inhibitor of the epidermal growth factor receptor (EGFR) mutant form T790M, with potential antineoplastic activity, which canbe used to treat NSCLC. Additionaly, HS-10296 mesylate could also inhibit other EGFR sensitive mutations, including G719X, del19, L858R and L861Q. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
