  Structure-activity relationships in prazosin-related compounds. 2. Role of the piperazine ring on .alpha.-blocking activity

  摘要：

  Several prazosin-related compounds have been synthesized and evaluated for their blocking activity toward a-adrenoreceptors. The structural modification performed on the prazosin structure included the replacement of the piperazine ring with 2,3-dialkylpiperazine or 1,2-cyclohexanediamine moieties to characterize a lipophilic binding pocket in the alpha1-adrenoreceptor surface. Cyclohexanediamine derivatives 3-6 were almost devoid of potency and selectivity, whereas dialkylpiperazine compounds 7-14 showed high affinity and selectivity toward alpha1-adrenoreceptors. The cis derivative 13 (cyclazosin) was the most potent and selective with an alpha1/alpha2 selectivity ratio value of 7800. The particular trend of antagonist activity within cis/trans stereoisomeric compounds not only supports the presence of a lipophilic binding area on alpha1-adrenoreceptor surface but also suggests that the lipophilic pocket is endowed with a well-defined size and spatial orientation. The most active compound of the series, 13, was tested also in vivo for antihypertensive activity on spontaneously hypertensive rats. It showed an interesting long-lasting hypotensive effect, very similar to that of doxazosin, which was statistically significant 12 h after oral administration.

  A straightforward procedure is described for the synthesis of piperazines from amines and 1,2-diols. The heterocyclization is catalyzed by [Cp*IrCl2]2 and sodium hydrogen carbonate and can be achieved with either toluene or water as solvent. The transformation does not require any stoichiometric additives and only produces water as the byproduct. The reaction can be performed between a 1,2-diamine

  the selective monoalkylation of amines with alcohols. The reaction goes through a series of consecutive steps in a cascade mode that involves: 1) the abstraction of hydrogen from the alcohol that produces the metal hydride and the carbonyl compound; 2) condensation of the carbonyl with the amine to give an imine, and 3) hydrogenation of the imine with the surface hydrogen atoms from the metal hydride

  已经发现，双官能金属Pd /碱（MgO）催化剂进行胺与醇的选择性单烷基化。该反应以级联方式经历一系列连续的步骤，包括：1）从产生金属氢化物和羰基化合物的醇中提取氢；2）羰基与胺的缩合反应生成亚胺，3）亚胺与金属氢化物的表面氢原子加氢。基于同位素和光谱学研究以及每个基本步骤的速率，提出了一种整体反应机理。该方法的控制步骤是从金属到亚胺的氢化物转移。通过改变钯的微晶尺寸，可以证明这是结构敏感的反应，而导致子产品的竞争过程则不然。基于这些基础，已经获得了具有小于2.5nm的直径的Pd微晶的高度选择性的催化剂。催化系统的高效率使我们能够将方法扩展到一锅合成哌嗪。
