(S)-(+)-8, synthesizing analogues with specific substituents; the structure-activity relationship (SAR) study was also expanded with the design and synthesis of other analogues characterized by a pyrrolo[2,1-b][1,3]benzothiazepine skeleton, substituted on the benzo-fused ring or on the pyrrole system. On the 9,10-dihydro analogues the substituents introduced on the pyrrole ring were detrimental to
最近,我们报道了9,10-二氢吡咯并[1,3]苯并硫氮杂derivative衍生物(S)-(+)-8作为新型非典型抗精神病药的药理特性。该化合物的最佳pK(i)5-HT(2A)/ D(2)比为1.21(pK(i)5-HT(2A)= 8.83; pK(i)D(2)= 7.79)。(S)-(+)-8与它的对映异构体相比,较低的D(2)受体亲和力可以通过难以达到最佳实现D(2)药效团所需的构象来解释。为了找到新型的非典型抗精神病药,我们进一步研究了(S)-(+)-8的核心结构,合成了具有特定取代基的类似物。结构与活性关系(SAR)的研究也随着吡咯并[2,1-b] [1,3]苯并硫氮杂skeleton骨架的其他类似物的设计和合成而扩展,在苯并稠合的环或吡咯体系上被取代。在9,10-二氢类似物上,吡咯环上引入的取代基不利于多巴胺和5-HT(2A)受体的亲和力,但在(S )-(+)-8导致有效的D(2)/
