  • PubMed Abstract: 

    A new series of pyrazolo[3,4-d]pyrimidine-3,6-diamines was designed and synthesized as potent and selective inhibitors of the nonreceptor tyrosine kinase, ACK1. These compounds arose from efforts to rigidify an earlier series of N-aryl pyrimidine-5-carboxamides. The synthesis and structure-activity relationships of this new series of inhibitors are reported. The most promising compounds were also profiled for their pharmacokinetic properties.
