evaluated as inhibitors of PI3 kinase p110alpha. In this series, the thieno[3,2-d]pyrimidine derivative 15e showed the strongest inhibitory activity against p110alpha, with an IC(50) value of 2.0 nM, and inhibited proliferation of A375 melanoma cells with an IC(50) value of 0.58 microM. Moreover, 15e was found to be selective for p110alpha over other PI3K isoforms and protein kinases, making it the
制备了一系列的4-吗啉代-2-苯基喹唑啉及其相关衍生物,并将其评估为PI3激酶p110alpha的抑制剂。在这个系列中,噻吩并[3,2-d]嘧啶衍生物15e对p110alpha的抑制作用最强,IC(50)值为2.0 nM,并抑制A375黑色素瘤细胞的增殖,IC(50)值为50。 0.58微米 此外,发现15e对p110alpha的选择性高于其他PI3K同工型和蛋白激酶,这使其成为选择性PI3K p110alpha抑制剂的第一个实例。
