摘要：

A series of 4-morpholino-2-phenylquinazolines and related derivatives were prepared and evaluated as inhibitors of PI3 kinase p110 alpha. In this series, the thieno[3,2-d]pyrimidine derivative 15e showed the strongest inhibitory activity against p110 alpha, with an IC50 value of 2.0 nM, and inhibited proliferation of A375 melanoma cells with an IC50 value of 0.58 mu M. Moreover, 15e was found to be selective for p110 alpha over other PI3K isoforms and protein kinases, making it the first example of a selective PI3K p110 alpha inhibitor. (c) 2006 Elsevier Ltd.
