    Configurationally stable analogs of styrylxanthines as A2A adenosine receptor antagonist
    摘要:
    Configurationally stable analogs of the potent, A(2A)-selective adenosine receptor (AR) antagonist 3,7-dimethyl-1-propargyl-8-styrylxanthine (8-styryl-DMPX, 3) were synthesized and investigated in radioligand binding assays for affinity to the high-affinity A(1)- and A(2A)-AR subtypes of rat brain. All derivatives prepared, including compounds in which the styryl double bond was replaced by a cyclopropane ring or a triple bond, or in which it was integrated into a (hetero) cyclic ring system, were less potent and less selective compared to the parent compound 3. The best compound of the present series was 8-(phenylethynyl)-DMPX (21), exhibiting a K-i value at A(2A)-AR of 300 nM and a > 10-fold selectivity versus A(1)-AR. In view of its configurational stability, 21 may be an interesting lead compound for the development of more potent A(2A) antagonists by introducing appropriate substituents in the phenyl ring. Based on conformational analysis of 8-styrylxanthine and 8-(2-naphthyl)xanthine derivatives, it is hypothesized that the bioactive conformation of (E)-8-styryl substituents with regard to the imidazole ring of the xanthine nucleus at A(2A)-AR may be nearly coplanar and cisoid, and may differ from the bioactive conformation of such xanthine derivatives at A(1)-AR.

    A New Versatile Synthesis of Xanthines with Variable Substituents in the 1-, 3-, 7- and 8-Positions
    摘要:
    从 3-取代的 6-氨基尿嘧啶开始,我们开发出了一种用于合成多种黄嘌呤的简便新方法。通过亚硝基化和还原反应生成相应的 5,6-二氨基脲嘧啶,并与羧酸缩合。在温和的条件下,可以选择性地在尿嘧啶环氮 N-1(对应于黄嘌呤 N-3)上对生成的酰胺进行烷基化。环闭合后,如果需要,在 7 位进行烷基化,可获得高产率的二取代黄嘌呤、三取代黄嘌呤或四取代黄嘌呤。可在 1 位引入敏感取代基,如丙-2-炔基。与制备黄嘌呤的标准程序相比,3-取代基的变化更为简便。

  • Synthesis of paraxanthine analogs (1,7-disubstituted xanthines) and other xanthines unsubstituted at the 3-position: structure-activity relationships at adenosine receptors

    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
    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。

    8-Arylethynylxanthine derivatives are potent, selective adenosine A2A receptor antagonists, which represent (potential) therapeutics for Parkinson’s disease, Alzheimer’s dementia, and the immunotherapy of cancer. 6-Amino-5-amidouracil derivatives are important precursors for the synthesis of such xanthines. We noticed an unexpected duplication of NMR signals in many of these uracil derivatives. Here, we present
