The discovery of a series of chromen-2-ones with selective affinity for the dopamine (DA) D4 receptor is described. Target compounds were tested for binding to cloned human DA D2L, D3, and D4.2 receptor subtypes expressed in Chinese hamster ovary K1 cells. Several compounds demonstrated high affinity (<20 nM, K(i)) and greater than 100-fold selectivity for DA D4.2 versus DA D2L receptors. The results
描述了一系列对多巴胺(DA)D4受体具有选择性亲和力的chromen-2-ones的发现。测试了目标化合物与在中国仓鼠卵巢K1细胞中表达的克隆的人DDA2L,D3和D4.2受体亚型的结合。与DA D2L受体相比,几种化合物对DA D4.2表现出高亲和力(<20 nM,K(i))和超过100倍的选择性。讨论SAR研究的结果。在测量[(3)H]胸苷摄取的DA D4功能测定中,目标化合物对D4.2受体表现出拮抗剂活性。当以20口服时,化合物22,7-[((2-苯基氨基乙基氨基)甲基] chromen-2-one增加大鼠海马中DOPA(L-3,4-二羟基苯基丙氨酸)的积累51%和纹状体中的23%毫克/千克
