both CCK-A and CCK-B receptors, while some of them bound with nanomolar affinity and high selectivity for kappa-opioid receptors. In particular, the 2-thienyl derivative 7A(X = H) with a K(i) = 0.50 nM represents a clear improvement with respect to tifluadom, showing a comparable potency but higher selectivity. The application of computational simulations and linear regression analysis techniques to the
一系列与tifluadom有关的2-取代的5-苯基-1,4-苯并二氮杂类化合物的合成和生物学评估(5),这是唯一同时充当κ阿片类激动剂和胆囊收缩素-A(CCK- A)拮抗剂,有报道。这些研究中使用的放射性配体结合模型是大鼠胰腺中的[(125)I](BH)-CCK-8(CCK-A),[(3)H]-(MENLE(28,31))-cck-8在豚鼠大脑皮层(CCK-B)和[(3)H] U-69593(kappa(1)),[(3)H] DAMGO(mu)和[(3)H] DADLE(delta)中在豚鼠的大脑中。所有标题化合物都没有对CCK-A和CCK-B受体的显着亲和力,而其中一些化合物与纳摩尔亲和力和对κ-阿片样受体的高选择性结合。尤其是,K(i)= 0.50 nM的2-噻吩衍生物7A(X = H)代表了对氟替洛芬的明显改善,表现出可比的效能,但选择性更高。通过将计算模拟和线性回归分析技术应用于豚
