A new class of cardiotonic agents characterized by a 2-pyridone structure was synthesized. Appropriate sym-2-dimethylaminomethylene-1,3-diones reacted with methylcyanoacetate to afford the desired compounds. These derivatives were evaluated for their ability in inducing cardiotonic response on guinea pig isolated myocardial preparations. Compound 8b increased atrial contractility to an extent which
合成了以2-吡啶酮结构为特征的一类新型强心药。适当的sym-2-二甲基氨基亚甲基-1,3-二酮与氰基乙酸甲酯反应,得到所需化合物。评估了这些衍生物对豚鼠分离的心肌制剂引起强心反应的能力。化合物8b增加了心房收缩力,其程度显着高于用作参考化合物的母体药物米力农。在8b上进行的药理学表征和对接研究突出了其通过3型PDE(PDE3)抑制作用的选择性作用机理。
