Synthesis, pharmacological activity, and chromatographic enantioseparation of new heterocyclic compounds of the aryloxyaminopropanol type derived from 4-hydroxyphenylalkanones
pharmacologically active compounds (β-adrenolytics) derived from 4-hydroxyphenylethanone and 4-hydroxyphenylpropan-1-one are reported. The compounds incorporate pyrrolidin-1-yl and 4-methylpiperazin-1-yl substituents in the hydrophilic part of the molecule and ethoxymethyl and methoxyethoxymethyl side chains on the aromatic ring in the lipophilic moiety. They were prepared by a four-step synthesis from 4-hydroxyalkanones
摘要在本文中,报道了一系列衍生自4-羟基苯基乙酮和4-羟基苯基丙烷-1-酮的六种药理活性化合物(β-肾上腺素)。该化合物在分子的亲水部分掺入了吡咯烷-1-基和4-甲基哌嗪-1-基取代基,并在亲脂部分的芳环上结合了乙氧基甲基和甲氧基乙氧基甲基侧链。它们是由4-羟基链烷酮经氯甲基,烷氧基甲基和环氧乙烷中间体通过四步合成制得的。通过TLC检查目标化合物的纯度,并通过IR,UV,1 H NMR和13的解释证实其结构1 H NMR谱。所得化合物的药理评价证实了它们的血管舒张活性和特异性抗异戊二烯活性。所有评估的化合物浓度一致。10 -6 mol dm -3抑制了去氧肾上腺素(8.22-33.7%)对离体大鼠主动脉的血管收缩作用。在浓度为50%的评估化合物进行预处理后,观察到了抑制异戊二烯正性变时性作用的能力,该作用是在孤立的自发跳动的大鼠心房进行的。10 -7和10 -6 mol dm -3。计算出的pA
