- Discovery of selective EGFR modulator to inhibit L858R/T790M double mutants bearing a N-9-Diphenyl-9H-purin-2-amine scaffold
-
Based upon the modeling binding mode of marketed AZD9291 with T790M, a series of N-9-Diphenyl-9H-purin-2-amine derivatives were designed and synthesized with the purpose to overcome the drug resistance resulted from T790M/L858R double mutations. The most potent compound 23a showed excellent enzyme inhibitory activities and selectivity with nanomolar IC50 values for both the single T790M and double T790M/L858R mutant EGFRs, and was more than 8-fold selective for wild type EGFR. Compound 23a displayed strong antiproliferative activity against the H1975 non-small cell lung cancer (NSCLC) cells bearing T790M/L858R. And it was less potent against A549 (WT EGFR and k-Ras mutation) and HT-29 (non-special gene type) cells, showing a high safety index.

- Structural optimization and structure-activity relationships of N 2-(4-(4-methylpiperazin-1-yl)phenyl)- N 8-phenyl-9 H -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)-N8-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-N2-(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.

- Aminopurine based JNK inhibitors for the prevention of ischemia reperfusion injury
-
In this Letter we describe the optimization of an aminopurine lead (1) with modest potency and poor overall kinase selectivity which led to the identification of a series of potent, selective JNK inhibitors. Improvement in kinase selectivity was enabled by introduction of an aliphatic side chain at the C-2 position. CC-359 (2) was selected as a potential clinical candidate for diseases manifested by ischemia reperfusion injury.
