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 (IC50: 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[1][2].
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[2]. Additionaly, HS-10296 mesylate could also inhibit other EGFR sensitive mutations, including G719X, del19, L858R and L861Q[3].
