A series of novel 1H-pyrazolo-[3,4-c]cyclophepta[1,2-c]thiophenes was prepared and screened at selected dopamine receptor subtypes. Compound 4 (NGB 4420) displayed high affinity and selectivity (>100-fold) for the D(4) over D(2) and other CNS receptors. This compound was identified as a D(4) antagonist via its attenuation of dopamine agonist-induced GTPgamma(35)S binding at D(4) receptor.
制备了一系列新颖的1H-吡唑并-[3,4-c]环庚[1,2-c]噻吩,并在选定的多巴胺受体亚型中进行了筛选。与D(2)和其他CNS受体相比,化合物4(NGB 4420)对D(4)表现出较高的亲和力和选择性(> 100倍)。该化合物通过其减弱多巴胺激动剂诱导的GTPgamma(35)S在D(4)受体上的结合被确定为D(4)拮抗剂。
