  Synthesis and Structure−Activity Relationships of 3,7-Dimethyl-1-propargylxanthine Derivatives, A_2A-Selective Adenosine Receptor Antagonists

  摘要：

  A series of 8-substituted derivatives of 3,7-dimethyl-1-propargylxanthine (DMPX) was synthesized and investigated as A(2A) adenosine receptor antagonists. Different synthetic strategies for the preparation of DMPX derivatives and analogues were explored. A recently developed synthetic procedure starting from 3-propargyl-5,6-diaminouracil proved to be the method of choice for the preparation of this type of xanthine derivatives. The novel compounds were investigated in radioligand binding studies at the high-affinity adenosine receptor subtypes A(1) and A(2A) and compared with standard A(2A) adenosine receptor antagonists. Structure-activity relationships were analyzed in detail. 8-Styryl-substituted DMPX derivatives were identified that exhibit high affinity and selectivity for A(2A) adenosine receptors, including 8-(m-chlorostyryl)-DMPX (CS-DMPX, K-i A(2A) = 13 nM, 100-fold selective), 8-(m-bromostyryl)-DMPX (BS-DMPX, K-i A(2A) = 8 nM, 146-fold selective), and 8-(3,4-dimethoxystyryl)-DMPX (K-i A(2A) = 15 nM, 167-fold selective). These and other novel compounds are superior to the standard A(2A) adenosine receptor antagonists KF17837 (4) and CSC (5) with respect to A(2A) affinity and/or selectivity.

  对位黄嘌呤类似物（1,7-二取代的黄嘌呤）和其他在3位未取代的黄嘌呤的合成：腺苷受体的结构活性关系。

  摘要：

  开发了用于制备各种3-未取代的黄嘌呤的合成方法，包括对黄嘌呤类似物（1,7-二取代的黄嘌呤）和1,8-二取代的黄嘌呤。1-取代的黄嘌呤的甲硅烷基化，然后在7-位的烷基化提供了一种简便的途径生产对黄嘌呤类似物。三（三甲基甲硅烷基）-6-氨基尿嘧啶的区域选择性烷基化提供了3-取代的6-氨基尿嘧啶，其通过标准方法转化为1,8-二取代的黄嘌呤。3-取代的5-环戊烷羧酰胺基和5-（苯甲酰基氨基）-6-氨基尿嘧啶的闭环需要剧烈的反应条件。在这些和其他具有1、3、7、8和9位取代基的黄嘌呤的结合测定中，确定了对大脑A1和A2腺苷受体的亲和力。为了在腺苷受体上具有高亲和力，必须在1位进行取代。1，3-二取代的黄嘌呤通常比1，7-二取代的黄嘌呤具有更高的亲和力。1,8-二取代的黄嘌呤对腺苷受体具有高亲和力。一些对A1受体具有高度选择性。

  paraxanthine analogs (1,7-disubstituted xanthines) and 1,8-disubstituted xanthines, were developed. Silylation of 1-substituted xanthines followed by alkylation at the 7-position provides a facile route to paraxanthine analogs. Regioselective alkylation of tris(trimethylsilyl)-6-aminouracil provides 3-substituted 6-aminouracils, which are converted to 1,8-disubstituted xanthines by standard procedures
