with the chromone ring system showed improved binding over compounds with coplanar substituents. The most potent compound at the sigma site, 7-[[7-(4-hydroxypiperidyl)heptyl]oxy]-2-phenylchromone (74), had receptor affinities (IC50) of 16 nM at the [3H]DTG site, 19 nM at the [3H]-(+)-3-PPP site, and 4000 nM (Ki) at the dopamine D2 receptor. The most selective compound examined, 6-[[6-(4-hydroxypiperi
已制备了一系列(氨基烷氧基)色酮,其成员在sigma结合位点有效结合(16-100 nM),在多巴胺D2受体和其他33个受体(第二信使系统)上弱结合(大于1000 nM),和离子通道。在σ受体上,氨基烷氧基侧链至色酮环的优选连接位置遵循等级顺序:7位大于5位大于6位。包含与色酮环系统不共面的2-取代基的色酮表现出比具有共面取代基的化合物更好的结合力。σ位点上最有效的化合物7-[[[7-(4-羟基哌啶基)庚基]氧基] -2-苯基色酮(74)在[3H] DTG位点19的受体亲和力(IC50)为16 nM。在[3H]-(+)-3-PPP位点处为nM,在多巴胺D2受体处为4000 nM(Ki)。研究中选择性最高的化合物6-[[[6-(4-羟基哌啶基)己基]-氧基] -2-环戊基色酮(58)在[3H] DTG位点的IC50为51 nM,在[3H]位点的IC50为55 nM。 -(+)-3-PPP位点,在多巴胺D2受体处21
