The GABA(A) agonists muscimol (1), 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol (THIP, gaboxadol, 3), and the partial GABA(A) agonist 5-(4-piperidyl)-3-isoxazolol (4-PIOL, 6a) and their respective 3-isothiazolol analogues thiomuscimol (2), thio-THIP (4), and thio-4-PIOL (7a) are ligands at the GABA(A) orthosteric (recognition) site. The structure-activity relationships (SARs) between these structures
GABA(A)激动剂muscimol(1),4,5,6,7-四氢异恶唑[5,4-c]吡啶-3-醇(THIP,gaboxadol,3)和部分GABA(A)激动剂5- (4-哌啶基)-3-异唑醇(4-PIOL,6a)及其各自的3-异噻唑醇类似物thiomuscimol(2),thio-THIP(4)和thio-4-PIOL(7a)是GABA( A)正构(识别)部位。这些结构之间的构效关系(SAR)是GABA(A)激动剂和竞争性拮抗剂的3D药效团模型的关键元素[Frolund,B .; 约根森(AT);Tagmose,L .; TB,Stensbol;HT,Vestergaard;Engblom,C .;美国,克里斯蒂安森;桑切斯 Krogsgaard-Larsen,P .;Liljefors,TJ Med。化学 2002,45,2454-2468]。在此模型的提示下,我们现在报告一系列7a类似
