on the structure-activity relationships in arylpiperazine group of serotonin ligands, 12 new derivatives containing quinazolidin-4(3H)-one (1-4), 2-phenyl-2,3-dihydrophthalazine-1,4-dione (5-8) or 1-phenyl-1,2-dihydropyridazine-3,6-dione (9-12) fragments were synthesized. The majority of the tested compounds (2, 4, 7, 8 and 10-12) showed a high affinity for 5-HT(1A) receptors (K(i)=11-54 nM) and two
在系统研究5-羟色胺配体的芳基哌嗪基团的结构-活性关系的基础上,发现了12种新的衍生物,它们分别包括喹唑啉素-4(3H)-一(1-4),2-苯基-2,3-二氢邻苯二甲酸-1,4。合成了-二酮(5-8)或1-苯基-1,2-二氢哒嗪-3,6-二酮(9-12)片段。大多数测试化合物(2、4、7、8和10-12)对5-HT(1A)受体(K(i)= 11-54 nM)表现出高亲和力,其中两个(1、2)发现活跃于5-HT(2A)位点(分别为16和68 nM)。体内测试的所有新的5-HT(1A)配体均对突触后5-HT(1A)受体具有拮抗活性,其中三个对突触前受体具有激动作用。此外,两个包含喹唑啉丁-4-酮片段的间氯苯基哌嗪衍生物均显示5-HT(2A)受体拮抗剂的特征。进一步测试了双5-HT(1A)/ 5-HT(2A)受体配体(2)的潜在精神活性。它在大鼠的冲饮试验中显示出独特的抗焦虑药样活性,并且与地西
