Two classes of trisubstituted pyrimidines related to PI-103 1 have been prepared and their inhibitory activities against phosphatidylinositol 3-kinase (PI3K) p110α were determined. From those with direct 6-aryl substitution compound 11a was the most potent inhibitor with an IC50 value of 62 nM, and showed similar activity against other class 1a PI3K isoforms tested, p110β and p110γ.

已制备了两类与 PI-103 1相关的三取代嘧啶,并测定了它们对磷脂酰肌醇 3-激酶 (PI3K) p110α 的抑制活性。从那些具有直接 6-芳基取代的化合物中,化合物11a是最有效的抑制剂,IC 50值为 62 nM,并且对测试的其他 1a 类 PI3K 亚型 p110β 和 p110γ 显示出相似的活性。当引入连接链时,如在第二个示例类中,化合物15f抑制 p110α,IC 50142 nM,对 p110α 显示出更高的选择性。两类化合物均显示出对 IGROV-1 卵巢癌细胞增殖的有希望的抑制作用。在旨在用结构等排体代替 3-酚基基序的化合物中,包含 4-吲唑基的类似物具有与母体酚相当的酶和细胞活性。
