摘 要:目的:观察野罂粟总生物碱中八种生物碱单体心血管应的构效关系。方法:采用离体实验观察单体对KCl所致兔胸主动脉环收缩的影响,并以Ver 作对照。结果:野罂粟碱(nudicauline,Ⅰ)、瑞芙热米定(refram idine,Ⅱ)、黑龙辛甲醚(am urensinine,Ⅳ)、黑龙辛(am urensine,Ⅴ)、野罂粟醇(am uroline,Ⅵ)和七号生物碱(Ⅶ)均可使KCl量- 效曲线不平行右移,最大反应压低,其IC50分别为0.20,0.80,0.16,0.60,0.60,0.16m m ol·L- 1。结论:野罂粟碱类(Ⅱ,Ⅳ,Ⅴ,Ⅶ)对经PDC钙内流抑制效果较强,其中以Ⅱ作用最强;原阿朴菲类(Ⅵ,ⅧA。Objective:To study relations between the structure and effects of eight monmers of papver nudicaule alkaloids on cardiovescular.Methods:Isolated rabbit aortic rings were used to study the effects of eight monomers on their contraction induced by KCl.Results:Monomer Ⅰ,Ⅱ,Ⅵ,Ⅴ,ⅥandⅦshifted KCl dose response curves to right in unparallel fashion and decreased the maximal response.The IC 50 of them were 0.2,0.08,0.16,0.60,0.60,0.16mmol.L -1 ,respectively.Conclusion:The inhibitory effect of the isopapaver group to Ca 2+ influx through PDC is more intensive than that of proapromorphine group. Monomer Ⅱ is the most intensive of the isopapaver group.
