Enantiomerically pure (2S,4R)-4-substituted glutamic acids were prepared and tested for homomeric GluR5 and GluR6 kainate subtype receptor affinity. Some of the 4-cinnamyl analogues showed high selectivity and potency (K(i) < 25 nM) for the GluR5 receptors. The greatest selectivity and potency were achieved with the 3-(2-naphthyl)prop-2-enyl compound. This compound, LY339434, has negligible activity
制备对映体纯的(2S,4R)-4-取代的谷氨酸,并测试其同质的GluR5和GluR6海藻酸酯亚型受体亲和力。一些4-肉桂基类似物对GluR5受体显示出高选择性和强效性(K(i)<25 nM)。用3-(2-萘基)丙-2-烯基化合物获得最大的选择性和效力。该化合物LY339434对AMPA和红藻氨酸受体GluR1,-2,-4和-6的活性可忽略不计。虽然,LY339434在文化海马神经元(大约EC(50)为2.5 microM)对NMDA受体显示激动剂活性,我们认为LY339434应该是研究GluR5海藻酸酯受体功能作用的有用药理工具。
