Abstract

Anaplastic lymphoma kinase (ALK) is a validated therapeutic target for treating echinoderm microtubule-associated protein-like 4 (EML4)-ALK positive non-small cell lung Cancer (NSCLC). We synthesized a series of 1,3,5-triazine derivatives and identified ASP3026 (14a) as a potent and selective ALK inhibitor. In mice xenografted with NCI-H2228 cells expressing EML4-ALK, once-daily oral administration of 14a demonstrated dose-dependent antitumor activity. Here, syntheses and structure-activity relationship (SAR) studies of 1,3,5-triazine derivatives are described.
