Prodrugs for PI3K: A series of substituted analogues of the phosphatidylinositol 3 kinase (PI3K) inhibitor LY294002 were prepared and found to potently inhibit the isolated enzyme but not MCF7 cell proliferation. Two tetrazolyl‐substituted analogues were further derivatized as prodrugs resulting in restoration of cell‐based activity. These data provide a conceptual model for development of tumor‐targeting
PI3K的前药:制备了磷脂酰肌醇3激酶(PI3K)抑制剂LY294002的一系列取代类似物,发现它们能有效抑制分离的酶,但不能抑制MCF7细胞的增殖。两个四唑基取代的类似物被进一步衍生为前药,从而恢复了基于细胞的活性。这些数据为细胞不可渗透的PI3K抑制剂的靶向肿瘤前药形式的开发提供了概念模型。
