adrenoceptors and selectivity in respect to dopamine (D(1-4)) and serotonin (5-HT(1A-1B) and 5-HT(2A,2C)) receptors. The most selective compound obtained, 3-[4-[1-(4-fluorophenyl)-5-(1-methyl-1,2,4-triazol-3-yl)-1H-indol-3-yl]-1-piperid inyl]propionitrile (15c), has affinities of 0.99, 3.2, and 9.0 nM for the alpha(1a), alpha(1b), and alpha(1d) adrenoceptor subtypes, respectively, and a selectivity for adrenergic
描述了一类新的5-杂芳基取代的1-(4-氟苯基)-3-(4-哌啶基)-1H-吲哚,它们具有高选择性,并且具有潜在的CNS活性α1-肾上腺素受体拮抗剂。所述化合物衍生自抗精神病药斯多吲哚。优化了5-杂芳基取代基和哌啶氮原子上的取代基的结构亲和性,从而优化了对α1肾上腺素受体的亲和力以及对多巴胺(D(1-4))和5-羟色胺(5-HT)的选择性(1A-1B)和5-HT(2A,2C))受体。获得的最具选择性的化合物3- [4- [1-(4-氟苯基)-5-(1-甲基-1,2,4-三唑-3-基)-1H-吲哚-3-基] -1 -哌啶基]丙腈(15c)对alpha(1a),alpha(1b)和alpha(1d)肾上腺素受体亚型的亲和力分别为0.99、3.2和9.0 nM,对多巴胺D2,D3和D4以及5-羟色胺5-HT(2A)和5-HT(2C)的肾上腺素α(1a)受体的选择性高于900,与哌唑嗪的选择性相当
