of dopamine D1 and -D2 receptors could be beneficial for the treatment of Parkinson's disease7,13, we prepared 5,6,7,8-tetrahydro-6-[propyl[2-(2-thienyl)ethyl]amino]-1,2-naphthalenediol (PTAT. 4), the diol analogue of N-0437 (3), as a potential mixed D1/D2-receptor agonist. The synthesis of 4 was carried out via a new strategy. The crucial step in this strategy was the conversion of 1-diazo-4-(2,3
基于多巴胺D 1和-D 2受体同时刺激可能有益于帕金森氏病7,13的假设,我们制备了5,6,7,8-tetrahydro-6- [propyl [2-(2噻吩基)乙基]氨基] -1,2-萘二酚(PTAT。4)中,N-0437(二醇类似物3),作为一个潜在的混合d 1 / d 2受体激动剂。4的合成是通过新策略进行的。该策略的关键步骤是将1-重氮-4-(2,3-二甲氧基苯基)-2-丁酮(15)转化为关键的中间体5,6-二甲氧基-2-四氢萘酮(9通过乙酸铑(II)催化的环化反应,然后在三氟乙酸的影响下进行转化。对PTAT(4)的多巴胺能性质的药理评估表明,该化合物对D 1和D 2受体均显示出高亲和力,并且具有与DAT(D 1 / D 2受体混合激动剂)DPAT(1)相同的诱导能力。利血平使小鼠的运动活动呈现急性运动性。
