were evaluated for their in vitro anticancer activity. Compounds 17 and 22c displayed an acceptable potent activity according to the DTP-NCI and were further evaluated in the NCI five doses assay. To validate our design, compounds with the highest mean growth inhibition percent were screened against the target PI3Kα and B-RafV600E to confirm their multi-kinase activity. The tested compounds showed promising
为了获得有效的抗增殖活性,扩展并利用基于结构和配体的药物设计方法来设计和改进小型化合物库。随后,基于 PI3K 和 B 所需的特征药效学特征,选择了32 种 7,8-二取代-1,3-二甲基-1 H-嘌呤-2,6(3 H ,7 H )-二酮衍生物进行合成-Raf 癌基因抑制。对所有合成化合物的体外抗癌活性进行了评估。化合物17和22c根据 DTP-NCI 显示出可接受的有效活性,并在 NCI 五次剂量测定中进一步评估。为了验证我们的设计,针对靶标 PI3Kα 和 B-Raf V600E筛选具有最高平均生长抑制百分比的化合物,以确认它们的多激酶活性。测试的化合物显示出有希望的多激酶活性。通过抑制 B-Raf WT、EGFR 和 VEGFR-2 以亚微摩尔范围内的IC 50来巩固化合物17和22c 的抗癌效力和针对 PI3Kα 和 B-Raf V600E 的多激酶活性。对最有效的化合物17和22c
