  Synthesis and Pharmacological Characterization of N³-Substituted Willardiine Derivatives:  Role of the Substituent at the 5-Position of the Uracil Ring in the Development of Highly Potent and Selective GLU_K5 Kainate Receptor Antagonists

  摘要：

  Some N-3-substituted analogues of willardiine such as 11 and 13 are selective kainate receptor antagonists. In an attempt to improve the potency and selectivity for kainate receptors, a range of analogues of 11 and 13 were synthesized with 5-substituents on the uracil ring. An X-ray crystal structure of the 5-methyl analogue of 13 bound to GLU(K5) revealed that there was allowed volume around the 4- and 5-positions of the thiophene ring, and therefore the 4,5-dibromo and 5-phenyl (67) analogues were synthesized. Compound 67 (ACET) demonstrated low nanomolar antagonist potency on native and recombinant GLU(K5)-containing kainate receptors (K-B values of 7 +/- 1 and 5 +/- 1 nM for antagonism of recombinant human GLU(K5) and GLU(K5)/GLU(K2), respectively) but displayed IC50 values > 100 mu M for antagonism of GLU(A2), GLU(K6), or GLU(K6)/GLU(K2).
