The first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), gefitinib and erlotinib significantly improved the therapeutic effect in non–small cell lung cancer (NSCLC) patients with EGFR mutation. However, the EGFRT790M mutation occurs and results in acquired resistance. Consequently, mutant selective third-generation EGFR TKIs represented by AZD9291 (Osimertinib) have been developed to offer more effective therapeutic treatment, but the clinical application is limited by the acquired resistance and the high costs. A series of 5-chloropyrimidine-2,4-diamine derivatives were synthesized and screened for in vitro antitumor activity on H1975 and A431 cells. XHL11 showed the strongest antineoplastic activity. Compared to AZD9291, XHL11 suppressed cellular proliferation and colony formation and induced apoptosis in H1975 cells with EGFRL858R/T790M mutation. In addition, XHL11 caused expression changes in EGFR and apoptosis-related pathways. Moreover, oral administration of XHL11 suppressed tumor progression in vivo in a H1975 subcutaneous xenograft model. These data demonstrated that XHL11 might be developed as a promising EGFR TKI for the therapeutic use of NSCLC patients.

Combination of anaplastic lymphoma kinase (ALK) inhibitor with histone deacetylases (HDAC) inhibitor could exert synergistically anti-proliferative effects on ALK positive non-small cell lung cancer (NSCLC) na?ve or resistant cells. In this work, we designed and synthesized a series of 2,4-pyrimidinediamine derivatives as dual ALK and HDAC inhibitors based on pharmacophore merged strategy. Among which, compound 10f displayed the most potent and balanced inhibitory activity against ALK (IC50 = 2.1 nM) and HDAC1 (IC50 = 7.9 nM), respectively. In particular, 10f was also potent against the frequently observed Crizotinib-resistant ALKL1196M (IC50 = 1.7 nM) as well as the Ceritinib-resistant ALKG1202R (IC50 = 0.4 nM) mutants. In antiproliferative activity assay, 10f exhibited impressive activity on ALK-addicted cancer cell lines at low micromole concentrations, which was comparable to that of Crizotinib and Ceritinib. Further flow cytometric analysis indicated that 10f could effectively induce cell death via cell apoptosis and cell cycle arrest. Taken together, these results suggested 10f would be a promising lead compound for the ALK-positive NSCLC treatment, especially the Ceritinib- or Crizotinib-resistant NSCLC.
