study, the potential in this scaffold has been explored through the synthesis and pharmacological characterization of a series of N- and O-substituted THAZ analogues. The analogues N-Bn-THAZ (3d) and O-Bn-THAZ (4d) were found to be potent agonists of the human 5-HT2A and 5-HT2C receptors. Judging from an elaborate pharmacological profiling at numerous other CNS targets, the 3d analogue appears to be
双环异恶唑的异恶唑-3-一个互变异构体5,6,7,8-四氢-4 H-异恶唑[4,5- d ] azepin-3-ol(THAZ)以前已被证明是弱的GABA A和甘氨酸受体拮抗剂。在本研究中,已经通过一系列N和O取代的THAZ类似物的合成和药理学表征探索了该支架的潜力。发现类似物N -Bn-THAZ(3d)和O -Bn-THAZ(4d)是人5-HT 2A和5-HT 2C的有效激动剂。受体。从对许多其他中枢神经系统靶点进行的详尽药理分析来看,该3d类似物似乎对这两种受体具有选择性。在位置识别Y迷宫模型中3d的施用大大改善了小鼠的认知能力,这种作用可以通过选择性5-HT 2C拮抗剂SB242084的共同施用而完全逆转。总之,作为新型的生物利用的认知增强剂,最有可能通过5-HT 2A和/或5-HT 2C受体介导其作用,异恶唑3d和4d构成了进一步药物化学发展的有趣线索。
