  N6-Substituted N-alkyladenosine-5'-uronamides: bifunctional ligands having recognition groups for A1 and A2 adenosine receptors

  摘要：

  The coronary vasoactivity of N-ethyl-1'-deoxy-1'-(6-amino-9H-purin-9-yl)-beta-D-ribofuranuronamide (NECA, 1) is over 2 orders of magnitude greater than that of adenosine, and the vasoactivity of certain N6-substituted adenosines is as much as 1 order of magnitude greater. Such results suggest that a combination of appropriate modifications at N6 and C-5' might additively augment the agonist potency of adenosine. At low temperatures 1-deoxy-1-(6-chloro-9H-purin-9-yl)-2',3'-O-isopropylidene- beta-D-ribofuranosyl chloride (5), obtained in three steps from inosine, reacts with amines to yield uronamides. The subsequent reaction of such uronamides with amines at elevated temperatures displaces the purine 6-chloro group to yield, after deblocking, N-alkyl(or aryl)-N6-alk(ar)yl-adenosine-5'-uronamides. At the coronary artery A2 receptor the potency of N6-modified analogues of 1 is similar to that of the N6-substituted adenosine, rather than equal to or greater than 1. As agonists in the A2 receptor-mediated stimulation of adenylate cyclase in plasma membranes of PC12 pheochromocytoma cells or human platelets, N6-substituted analogues of 1 are intermediate between the high potency of 1 and the lower potency of the N6-substituted adenosines. At the A1 receptor of rat brain the potency of an N6-substituted analogue of 1 is often greater than that of the corresponding N6-substituted adenosine. At all four receptors, replacing the ethyl group of N-ethyl-N6-3-pentyladenosine-5'-uronamide by larger alkyl groups reduces potency; amides of secondary amines are inactive or have only marginal activity. Analogues of 1 containing a chiral center in the N6 substituent retain the stereoselectivity characteristic of each of the four receptors. Thus, at either A1 or A2 adenosine receptors, adenosine analogues interact with both the N6 and the C-5' receptor regions. However, the effects of N6 and C-5' modifications on potency are less than additive, evidence that the interaction of a substituent with its receptor region influences the interaction of other substituents with their respective receptor regions.

  N6-(indol-3-yl)alkyl derivatives of adenosine were synthesized. The adenosine receptor affinity and the antinociceptive activity of these compounds were assessed in binding studies and the phenylbenzoquinone-induced writhing test. Most of these analogues exhibited a potent analgesic activity without side effects. Among them, compound 3c (UP 202-32) bound to A1 (Ki = 110 nM) and A2 (Ki = 350 nM) adenosine receptors

  合成了腺苷的新型N6-（吲哚-3-基）烷基衍生物。在结合研究和苯基苯醌诱导的扭体试验中评估了这些化合物的腺苷受体亲和力和抗伤害感受活性。这些类似物中的大多数表现出有效的镇痛活性而没有副作用。其中，化合物3c（UP 202-32）以特定方式与A1（Ki = 110 nM）和A2（Ki = 350 nM）腺苷受体结合，因为它不与许多其他受体（尤其是阿片样物质结合位点）相互作用。苯基苯醌试验（ED50 = 3.3 mg / kg口服）中的抗伤害感受活性被8-环戊基茶碱拮抗，表明腺苷能机制是该化合物观察到的镇痛作用的基础。

  A novel compound, N6‐(4‐hydroxybenzyl)adenosine, isolated from Gastrodia elata and which has been shown to be a potential therapeutic agent for preventing and treating neurodegenerative disease, was found to target both the adenosine A2A receptor (A2AR) and the equilibrative nucleoside transporter 1 (ENT1). As A2AR and ENT1 are proximal in the synaptic crevice of striatum, where the mutant huntingtin

  从天麻中分离出的一种新型化合物N 6-（4-羟基苄基）腺苷已被证明是预防和治疗神经退行性疾病的潜在治疗剂，同时靶向腺苷A 2A受体（A 2A R ）和平衡核苷转运蛋白1（ENT1）。由于A 2A R和ENT1位于突变体亨廷顿聚集体所在的纹状体突触缝隙的近端，因此同时靶向这两种膜蛋白的双重作用化合物可能有益于亨廷顿舞蹈病的治疗。为了设计所需的双作用化合物，A 2A的药效团模型构建了R激动剂和ENT1抑制剂。因此，如果预测的活性在可接受的范围内，则通过腺苷的化学修饰，特别是在N 6和C 5'位置，设计和合成潜在的活性化合物。实际上，某些设计的化合物对A 2A R和ENT1均显示出显着的双重作用。两种药效基团模型在预测和测得的活性之间均显示出良好的统计相关性。与竞争性配体结合测定结果相一致，这些化合物还可以防止血清剥夺的PC12细胞凋亡，从而在神经保护中发挥关键作用，并在神经退行性疾病的治疗中具有潜在的实用性。
