  Synthesis of 3-(5-bromo-2,3-dimethoxy-phenyl)-[1, 2, 4] oxadiazole analogues and their evaluation as anti-Parkinson′s agents

  摘要：

  A series of 3-(5-bromo-2,3-dimethoxy-phenyl)-[1, 2, 4] oxadiazole derivatives was prepared and their evaluation for anti-Parkinson's activity was measured in vivo using albino rats. The result of the biological activity studies indicated that some of the synthesized compounds have good agonistic activity on the dopamine receptors and a few of them were also found to be free from neurotoxicity. Thus these compounds might be useful ligands for studying the functional role of dopamine receptors in vivo. The high log P value of the compounds indicates that they should easily cross the blood-brain barrier (log P > 2.6).

  Construction of Hydroxylated Alkaloids (.+-.)-Mannonolactam, (.+-.)-Deoxymannojirimycin, and (.+-.)-Prosopinine through Aza-Annulation

  摘要：

  The aza-annulation of beta enamino carbonyl substrates with acrylate derivatives provides an efficient and convenient route for the regioselective construction of delta-lactams. This two-step ring-forming sequence involved initial generation of the benzyl enamine through either a condensation or conjugate addition reaction with BnNH(2), followed by aza-annulation with acryloyl chloride or acrylic anhydride. Controlled by the rigid framework of the intermediate lactam, introduction of ring substituents was accomplished with high relative stereoselectivity. The carbonyl functionality, which was necessary to direct the regioselectivity of the aza-annulation reaction, was then transformed into a protected hydroxyl substituent through Baeyer-Villiger oxidation. The resultant delta-lactam product was used as a valuable intermediate in the synthesis of three natural products. Subsequent modification of this delta-lactam gave the naturally occurring alpha-mannosidase inhibitors (+/-)-mannonolactam and (+/-)deoxymannojirimycin, while synthesis of the alkaloid (+/-)-prosopinine was accomplished through homologation of the lactam carbonyl.

  same region resulted in a total loss of affinity for both dopamine receptor subtype binding sites. The most selective compound in this series is 2-(5-bromo-2,3-dimethoxyphenyl)-4-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolinomethyl)imidazole (5i), which has a D(3) receptor affinity of 21nM and a 7-fold selectivity for D(3) versus D(2) receptors. The binding affinity for sigma(1) and sigma(2) receptors was

  制备了一系列的2-（2,3-二甲氧基苯基）-4-（氨基甲基）咪唑衍生物，并使用体外结合试验测量了它们对多巴胺D（2）和D（3）受体的亲和力。还制备了几种恶二唑类似物，并测试了它们对多巴胺D（2）和D（3）受体的亲和力。受体结合研究的结果表明，在苯环和碱性氮之间并入咪唑部分并不会显着增加对多巴胺D（3）受体的选择性，而在同一区域并入恶二唑会导致总的两个多巴胺受体亚型结合位点的亲和力丧失。该系列中选择性最高的化合物是2-（5-溴-2,3-二甲氧基苯基）-4-（6,7-二甲氧基-1,2,3,4-四氢异喹啉甲基）咪唑（5i），具有21nM的D（3）受体亲和力，对D（3）与D（2）受体的选择性是7倍。还测量了对sigma（1）和sigma（2）受体的结合亲和力，结果表明几种类似物是选择性的sigma（1）受体配体。
