the excitatory amino acid antagonist activity in a series of decahydroiso-quinoline-3-carboxyic acids, and within this series found the potent and selective AMPA antagonist (3SR,4aRS,6RS,8aRS)-6-(2-(1H-tetrazol-5-yl )ethyl) decahydroisoquinoline-3-carboxylic acid (1). In this and the preceding paper, we looked at the structure-activity relationships for AMPA antagonist activity in this series of compounds
我们探索了一系列十氢异喹啉-3-羧酸中的兴奋性氨基酸拮抗剂活性,并在该系列中发现了有效的选择性AMPA拮抗剂(3SR,4aRS,6RS,8aRS)-6-(2-(1H -四唑-5-基)乙基)十氢异喹啉-3-羧酸(1)。在本文中,我们研究了该系列化合物中AMPA拮抗剂活性的构效关系。我们已经表明1具有最佳的立体化学阵列,并且AMPA拮抗剂活性对于将四唑与双环核分开的二碳间隔基而言是最大的。在本文中,我们探讨了改变远端酸的作用以及许多类似物的绝对立体化学偏好。我们研究了各种不同的酸性生物异构体,包括五元杂环酸,例如四唑,1,2,4-三唑和3-异恶唑酮;羧酸,膦酸和磺酸;和酰基磺酰胺。对大鼠皮质组织中的化合物抑制AMPA([3H] AMPA),NMDA([3H] CGS 19755)和海藻酸([3H] kainic acid)受体选择性放射性配体结合的能力及其功能进行了评估抑制由AMPA(40 microM),NMDA(40
