This paper reports the synthesis and AMPA, Gly/NMDA, and KA receptor binding affinities of a new set of 1,9-disubstituted-8-chloro-pyrazolo[1,5-c]quinazoline-2-carboxylates 2-34. Binding data show that, in general, compounds 2-34 bind to the AMPA receptor with good affinity and selectivity. In particular, the obtained results indicate that the contemporary presence of a 1,2-dicarboxylic acid moiety
本文报道了一组新的1,9-二取代-8-氯-吡唑并[1,5-c]喹唑啉-2-羧酸酯2-34的合成及AMPA,Gly / NMDA和KA受体结合亲和力。结合数据表明,化合物2-34通常以良好的亲和力和选择性与AMPA受体结合。尤其是,获得的结果表明,PQZ系统中1,2-二羧酸部分和合适的苯并取代基的当代存在对于获得选择性AMPA受体拮抗剂很重要。此外,这项研究表明,在9位(化合物33-34)上存在2-羧基苯甲酰氨基取代基对于获得选择性KA受体拮抗剂很重要。还测试了一些选定的化合物在AMPA和NMDA受体离子通道上的功能拮抗活性。
