This paper describes identification of the first-in-class multi-target adenosine A2A receptor antagonists-carbonic anhydrase (CA) IX and XII inhibitors, as new potential antitumor agents. To obtain the multi-acting ligands, the 8-amino-2,6-diphenyltriazolo [4,3-a]pyrazin-3-one, a potent adenosine hA2A receptor (AR) antagonist, was taken as lead compound. To address activity against the tumor-associated
本文介绍了鉴定作为多种潜在抗肿瘤药物的一流的多靶腺苷A 2A受体拮抗剂-碳酸酐酶(CA)IX和XII抑制剂。为了获得多作用配体,将有效的腺苷hA 2A受体(AR)拮抗剂8-氨基-2,6-二苯基三唑并[4,3-a]吡嗪-3-one作为主要化合物。为了解决针对肿瘤相关的CA同工型的活性,通过在6-苯基环上或通过不同间隔基连接到前者的苯基侧基上引入不同的取代基(OH,COOH,CONHOH,SO 2 NH 2)进行修饰。在新的triazolopyrazines 1 - 23,最活跃的是具有磺酰胺残基的那些。衍生物20的特征是在6苯基环的对位通过CONH(CH 2)2 CONH间隔基连接的4-磺酰胺基苯基残基,显示了在三个靶点上活性的最佳组合。实际上,它以纳摩尔浓度(K i = 5.0和27.0 nM)抑制了肿瘤相关的hCA IX和XII同工酶,并且对hA 2A AR(K i = 108 nM
