The present work reports the synthesis of 20 novel fluorine-containing quinoline and pyrimido[4,5-b]quinolinederivatives bearing a sulfonamide moiety. The new synthesized compounds were designed in compliance with the general pharmacophoric requirements for carbonic anhydrase (CA) inhibiting anticancer drugs, as this may play a role in their anticancer activity. All the newly synthesized compounds
本工作报告了20种新型的含氟喹啉和带有磺酰胺部分的嘧啶并[4,5- b ]喹啉衍生物的合成。设计新合成的化合物符合抑制碳酸酐酶(CA)的抗癌药物的一般药理学要求,因为这可能在其抗癌活性中起作用。评价所有新合成的化合物对人乳腺癌细胞系(MCF7)的体外抗癌活性。与参考药物阿霉素(IC 50 = 71.8μM)相比,化合物11和12表现出更好的活性,IC 50值分别为52.6μM和67.3μM。另一方面,化合物6,图10和13显示了与参考药物阿霉素相当的IC 50值(分别为71.8μM,69.8μM和70.8μM)。另外,为了预测这些化合物在同工酶活性位点上的亲和力和方向,将合成的化合物对接到人碳酸酐酶同工酶Ⅱ(hCA II)活性位点上。另外,选择活性最高的化合物11和12并评估其增强γ射线对细胞的杀伤作用的能力。
