  A large number of 2- (phenylpiperazinoalkoxyphenyl) thiazolidine-3-thiocarboxamides and the corresponding carboxamides (II) were synthesized and tested for inotropic activity in anesthetized dogs. Compounds II were prepared from a hydroxybenzaldehyde (III) through the intermediates (IV, V, and X). Structure-activity relationships (SAR) were investigated by varying the structural parameters. Transposition of the piperazinoalkoxyl group to the meta or para position from the ortho position caused a marked fall in activity. Conversion of the thiocarboxamido to a carboxamido group caused a marked increase in activity. This tendency was generally observed in this series of compounds and constitutes a major deviation from the SAR in the simple 2-phenylthiazolidine series. With regard to effects of the length of the aminoalkoxy chain, the ethoxy derivatives were generally more potent than higher analogues. Lengthening of the N-alkyl group in the (thio) carboxamido group generally caused a decrease in activity. Among the various derivatives synthesized, II15 was found to be approximately one hundred times more potent than amrinone with a long duration of action.

  大量2-（苯基哌嗪基烷氧苯基）噻唑烷-3-硫代羧酰胺及其相应羧酰胺（II）被合成并在麻醉犬中测试其强心活性。化合物II通过羟基苯甲醛（III）及其中间体（IV、V和X）制备。通过改变结构参数来研究结构-活性关系（SAR）。将哌嗪基烷氧基团从邻位位置移至间位或对位导致活性显著下降。将硫代羧酰胺转变为羧酰胺基团导致活性显著增加。这种趋势在这一系列化合物中普遍存在，并构成与简单2-苯基噻唑烷系列SAR的主要偏离。关于氨基烷氧链长度的影响，乙氧基衍生物通常比更高级的类似物更有效。在（硫代）羧酰胺基团中延长N-烷基通常导致活性下降。在合成的各种衍生物中，II15被发现其效力约为氨力农的一百倍，且作用时间较长。
