  名称：

  Centrally acting .alpha.1-adrenoceptor agonists based on hexahydronaphth[2,3-b]-1,4-oxazines and octahydrobenzo[g]quinolines

  摘要：

  Centrally acting alpha(1)-agonists may be of therapeutic value in dementias and other CNS disorders characterized by symptoms of noradrenergic insufficiency. Therefore, on the basis of known peripherally acting alpha(1)-agonists two new groups of centrally acting alpha(1)-agonists with improved lipophilicity, the hexahydronaphth[2,3-b]-1,4-oxazines type A and the octahydrobenzo[g]quinolines type B were designed. The N-methylated derivatives 14 and 33 demonstrate potent, direct agonistic activity at postjunctional alpha(1)-receptors. Ring substituent alterations in compounds of type A and B change the potency of compounds on the rabbit ear artery by over 3 orders of magnitude (pD2 = 5.35-8.40). The efficacy of these compounds varies from 42 to 110%. These alpha(1)-agonists which were selective in the pithed rat increase vigilance in rats. Compound 14 was found to be a centrally acting alpha(1)-agonist with good tolerability in different animal species and in healthy volunteers. Furthermore, 14 selectively stimulates the breakdown of phosphatidylinositol in rat cerebral cortex slices. In vivo, the compound reverses behavioral deficits in animals which received noradrenergic lesions following DDC or DSP4 treatment. Oxazine 14 and its close derivatives are by far more lipophilic than commonly known alpha(1)-agonists. This is demonstrated in a ClogP-PROBIS plot.

  The preparation of the cis- and trans-isomers of 6- and 9-methoxy-1,2,3,4,4a,5,10,10a-octahydrobenzo[g]-quinoline is reported. The syntheses involved reductions of cyclic iminium chlorides, which afforded the diastereomers conveniently and in good yields. Small cis/trans ratios were obtained with NaCNBH3 as the reducing agent. Catalytic hydrogenation using PtO2 in THF or t-BuOH gave the largest cis/trans

  报道了6-和9-甲氧基-1,2,3,4,4a，5,10,10a-八氢苯并[g]-喹啉的顺式和反式异构体的制备。合成涉及环状亚氯化亚胺的还原，这方便地且以高收率提供了非对映异构体。用NaCNBH 3作为还原剂可获得小的顺式/反式比率。使用PtO 2在THF或t-BuOH中的催化加氢得到最大的顺式/反式比。制备N-苄基衍生物以允许确定相对立体化学。
