    选择性腺苷A2A受体拮抗剂对单胺氧化酶B的抑制作用。
    摘要:
    对A(2A)受体亚型具有选择性的腺苷受体拮抗剂(A(2A)拮抗剂)正在作为可能的治疗药物,用于对症治疗与帕金森氏病(PD)相关的运动障碍。PD的MPTP小鼠模型中的最新研究结果表明,A(2A)拮抗剂可能具有神经保护特性。由于单胺氧化酶B(MAO-B)抑制剂还增强运动功能并降低MPTP神经毒性,因此我们研究了几种A(2A)拮抗剂和结构相关化合物对MAO-B的抑制作用,以确定是否抑制MAO-B可能有助于观察到的神经保护作用。这些研究的结果已经确定,所有从(E)-8- styrylxanthinyl衍生的A(2A)拮抗剂在体外均表现出显着的MAO-B抑制特性,其K(i)值在低micro M至nM范围内。该系列产品包括(E)-1,3-二乙基-8-(3,4-二甲氧基苯乙烯基)-7-甲基黄嘌呤(KW-6002),这是一种有效的A(2A)拮抗剂和神经保护剂,正在临床试验中。这些研究的结果表明,MAO-B

    8-苯乙烯基黄嘌呤作为A2选择性腺苷拮抗剂的构效关系。
    摘要:
    合成了一系列取代的1,3,7-烷基黄嘌呤的8-苯乙烯基衍生物作为潜在的A2选择性腺苷受体拮抗剂,并在放射性配体结合实验中研究了对大鼠脑A1和A2受体的效价。在黄嘌呤7位上,受体结合中仅容忍小的疏水取代基。7-甲基类似物对A2和A1受体的选择性比相应的7-H类似物高大约1个数量级。1,3-二甲基黄嘌呤衍生物比相应的1,3-二烯丙基,二乙基或二丙基衍生物倾向于对A2-受体更具选择性。在3-(单取代)和3,5-(二取代)位置上苯环的取代是有利的。1,3,7-三甲基-8-(3-氯苯乙烯基)黄嘌呤是中等效力的(Ki vs [3H] CGS 21680为54 nM)和高度A2选择性(520倍)腺苷拮抗剂。1,3,7-三甲基-8-[(3-羧基-1-氧丙基)氨基]苯乙烯基]黄嘌呤具有很高的A2选择性(250倍),并且具有更高的水溶性(最大19 mM)。1,3-二丙基-7-甲基-8-(3,5-二甲氧基苯乙烯基)黄嘌呤是有效的(Ki

  • Synthesis and Structure−Activity Relationships of 3,7-Dimethyl-1-propargylxanthine Derivatives, A<sub>2A</sub>-Selective Adenosine Receptor Antagonists

    日期:1997.12.1
    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.
