N3-substitution of the uracil ring of willardiine with a variety of carboxyalkyl or carboxybenzyl substituents produces AMPA and kainate receptor antagonists. In an attempt to improve the potency and selectivity of these AMPA and kainate receptor antagonists a series of analogues with different terminal acidic groups and interacidic group spacers was synthesized and pharmacologically characterized.
威拉二因的尿嘧啶环被各种羧基烷基或羧基苄基取代基的 N3 取代产生 AMPA 和红藻氨酸受体拮抗剂。为了提高这些AMPA和红藻氨酸受体拮抗剂的效力和选择性,合成了一系列具有不同末端酸性基团和酸性基团间隔物的类似物并进行了药理学表征。(S)-1-(2-Amino-2-carboxyethyl)-3-(2-carboxythiophene-3-ylmethyl)pyrimidine-2,4-di one (43, UBP304) 对天然 GLU(K5 )-含红藻氨酸受体(K(D) 0.105 +/- 0.007 microM 与天然 GLU(K5) 上的红藻氨酸;K(D) 71.4 +/- 8.3 microM 与天然 AMPA 受体上的 (S)-5-氟威拉二碱)。在重组人 GLU(K5)、GLU(K5)/GLU(K6) 和 GLU(K5)/GLU(K2) 上,K(B) 值为 0.12 +/-
