In order to discover new anticancer agents, 25 novel 2,4-diamino-5-methyleneaminopyrimidine derivatives were designed and synthesized based on our previous work via a ring-opening strategy. Among them, compared with 5-FU, compound 7i exhibited 4.9-, 2.9-, 2.1-, and 3.0-fold improvement in inhibiting HCT116, HT-29, MCF-7, and HeLa cells proliferation with IC50 values of 4.93, 5.57, 8.84, and 14.16 μM

Structural Optimization and Structure–Activity Relationships of <i>N</i><sup>2</sup>-(4-(4-Methylpiperazin-1-yl)phenyl)-<i>N</i><sup>8</sup>-phenyl-9<i>H</i>-purine-2,8-diamine Derivatives, a New Class of Reversible Kinase Inhibitors Targeting both EGFR-Activating and Resistance Mutations
This paper describe the structural optimization of a hit compound, N-2-(4-(4-methylpiperazin-1-yl)phenyl)-N-8-phenyl-9H-purine-2,8-diamine (1), which is a reversible kinase inhibitor targeting both EGFR-activating and drug-resistance (T790M) mutations but has poor binding affinity. Structure-activity relationship studies led to the identification of 9-cyclopentyl-N-2-(4-(4-methylpiperazin-1-yl)phenyl)-N-8-phenyl-9H-purine-2,8-diamine (9e) that exhibits significant in vitro antitumor potency against the non-small-cell lung cancer (NSCLC) cell lines HCC827 and H1975, which harbor EGFR-activating and drug-resistance mutations, respectively. Compound 9e was further assessed for potency and selectivity in enzymatic assays and in vivo anti-NSCLC studies. The results indicated that compound 9e is a highly potent kinase inhibitor against both EGFR-activating and resistance mutations and has good kinase spectrum selectivity across the kinome. In vivo, oral administration of compound 9e at a dose of 5 mg/kg caused rapid and complete tumor regression in a HCC827 xenograft model, and an oral dose of 50 mg/kg initiated a considerable antitumor effect in an H1975 xenograft model.
