triazolopyridazine ring. 3-Furan and 5-methylisoxazole were shown to be optimal for GABA(A)alpha5 functional selectvity. 3-(5-Methylisoxazol-3-yl)-6-(2-pyridyl)methyloxy-1,2,4-triazolo[3,4-a]phthalazine (43) was identified as a full inverse agonist at the GABA(A)alpha5 subtype with functional selectivity over the other GABA(A) receptor subtypes and good oral bioavailability.
鉴定一系列新颖的7,8,9,10-四氢-(7,10-乙醇)-1,2,4-三唑并[3,4-a]酞嗪作为GABA(A)alpha5反向激动剂,其中描述了对α5-的苯并二氮杂pine结合位点具有超过α1-,α2-和α3的GABA(A)受体亚型的结合和功能(功效)选择性。结合选择性在很大程度上取决于稠合环系统的平面度,而功能选择性则取决于三唑并哒嗪环3位杂环的性质。3-呋喃和5-甲基异恶唑被证明对GABA(A)alpha5功能选择性是最佳的。3-(5-甲基异恶唑-3-基)-6-(2-吡啶基)甲氧基-1,2,4-三唑[3,
