acid derivatives enhances cardiotonic activity in II in contrast to I, wherein analogous substitution eliminated activity. A linear correlation between contractile force (CF) increase and cyclic nucleotide phosphodiesterase fraction III (PDE-III) inhibition by the title compounds was determined. The isoquinoline derivatives were characteristically short-acting cardiotonic agents with good potency and
制备了一系列异喹啉-3-醇衍生物(II)作为临床强心药贝马龙酮(ORF 16600,I)的类似物。尽管在许多方面,II的强心活性的结构要求与贝马龙酮相似,但仍需注意系列之间的某些差异。我们的结构活性研究表明,II对烷氧基取代作用的敏感性不如I,并且更重要的是,与I相比,烷基,卤素或烷烃羧酸衍生物对II进行的4取代增强了II的心脏活性,其中类似的取代消除了活性。确定了收缩力(CF)增加与环状核苷酸磷酸二酯酶组分III(PDE-III)对标题化合物的抑制之间的线性关系。
