  摘要：

  新型的2,4,5-三取代的咪唑基胆囊收缩素2（CCK（2））受体拮抗剂的结构的系统优化提供了具有纳摩尔受体亲和力的类似物。这些化合物的效价现在与基于双环杂芳族化合物5（JB93182）和6（JB95008）的效价相当，后者使用基于场点的分子建模方法设计了初始实例。通过抑制五肽胃泌素刺激的清醒犬的酸分泌可以判断，它们也具有口服活性，这与基于双环杂芳香族化合物的化合物（由于胆道消除而无效）相反。通过用醚氧置换特定的亚甲基来增加亲水性，如3-{[5-（金刚烷-1-基氧甲基）-2-环己基-1H-咪唑-4-羰基]氨基}苯甲酸中的苯甲酸（53）一样，对受体亲和力的影响很小，但显着提高了口服药的效力。 。比较血浆药代动力学和对十二指肠内推注53和6后五肽胃泌素刺激的酸输出的抑制作用，表明53吸收良好，半衰期更长，并且不受早期系列的消除途径的影响。

• Scaffold Hopping with Molecular Field Points:  Identification of a Cholecystokinin-2 (CCK₂) Receptor Pharmacophore and Its Use in the Design of a Prototypical Series of Pyrrole- and Imidazole-Based CCK₂ Antagonists

  A new molecular modeling approach has been used to derive a pharmacophore of the potent and selective cholecystokinin-2 (CCK2) receptor antagonist 5 (JB93182), based on features shared with two related series. The technique uses "field points" as simple and effective descriptions of the electrostatic and van der Waals maxima and minima surrounding a molecule equipped with XED (extended electron distribution) charges. Problems associated with the high levels of biliary elimination of 5 in vivo required us to design a compound with significantly lower molecular weight without sacrificing its nanomolar levels of in vitro activity. Two new series of compounds were designed to mimic the arrangement of field points present in the pharmacophore rather than its structural elements. In a formal sense, two of the three amides in 5 were replaced with either a simple pyrrole or imidazole, while some features thought to be essential for the high levels of in vitro activity of the parent compounds were retained and others deleted. These compounds maintained activity and selectivity for this receptor over CCK1. In addition, the reduction in molecular weight coupled with lower polarities greatly reduced levels of biliary elimination associated with 5. This makes them good lead compounds for development of drug candidates whose structures are not obviously related to those of the parents and represents the first example of scaffold hopping using molecular field points.

  The systematic optimization of the structure of a novel 2,4,5-trisubstituted imidazole-based cholecystokinin-2 (CCK(2)) receptor antagonist afforded analogues with nanomolar receptor affinity. These compounds were now comparable in their potency to the bicyclic heteroaromatic-based compounds 5 (JB93182) and 6 (JB95008), from which the initial examples were designed using a field-point based molecular
