This article deals with the synthesis and the activities of some 1,5-dialkyl-3-arylureido-1,5-benzodiazepin-2,4-diones which were prepared as potential CCK2 antagonists, with the intention to find a possible follow up of our lead compound GV150013, showing an improved pharmacokinetic profile. The phenyl ring at N-5 was replaced with more hydrophilic substituents, like alkyl groups bearing basic functions
本文讨论了作为潜在CCK2拮抗剂制备的一些1,5-二烷基-3-芳基脲基-1,5-苯并二氮杂-2,4-二酮的合成和活性,目的是寻找可能的CCK2拮抗剂。我们的先导化合物GV150013,具有改善的药代动力学特性。N-5处的苯环被更具亲水性的取代基所取代,例如带有碱性功能的烷基。在某些情况下,还可以实现外消旋键中间体3-氨基-苯并二氮杂also的拆分。在迄今已合成和表征的此类化合物中,选择了5-吗啉代乙基衍生物54作为GV150013的潜在随访方法,并提交进一步评估。
