  Progress toward the Development of a Safe and Effective Agent for Treating Reentrant Cardiac Arrhythmias:  Synthesis and Evaluation of Ibutilide Analogues with Enhanced Metabolic Stability and Diminished Proarrhythmic Potential

  摘要：

  A series of ibutilide analogues with fluorine substituents on the heptyl side chain was prepared and evaluated for class III antiarrhythmic activity, metabolic stability, and proarrhythmic potential. It was found that fluorine substituents stabilized the side chain to metabolic oxidation. Many of the compounds also retained the ability to increase the refractoriness of cardiac tissue at both slow and fast pacing rates. The potential for producing polymorphic ventricular tachycardia in the rabbit model was dependent on the chirality of the benzylic carbon. The S-enantiomers generally had less proarrhythmic activity than the corresponding racemates. One compound from this series (45E, trecetilide fumarate) had excellent antiarrhythmic activity and metabolic stability and was devoid of proarrhythmic activity in the rabbit model. It was chosen for further development.

  fluoroalkyl carboxylic acids as the sole reagents. Hydrotrifluoro-, difluoro-, monofluoro- and perfluoroalkylation are all demonstrated, with broad scope, mild conditions (redox neutral) and potential for late-stage modification of bioactive molecules. Critical to success is overcoming the exceedingly high redox potential of feedstock fluoroalkyl carboxylic acids such as trifluoroacetic acid by leveraging cooperative

  在药物中掺入氟烷基基序可以增强母体分子的治疗特性。烯烃的氢氟烷基化已成为获得多种氟烷基化化合物的有前途的途径;然而，目前的方法需要超化学计量氧化剂、昂贵/氧化性氟烷基化试剂和贵金属，并且通常表现出有限的范围，因此非常需要解决这些限制的通用方案。在这里，我们报道了烯烃的氢氟烷基化反应，其中廉价、丰富且可用 氟烷基羧酸 作为唯一试剂。氢三氟、二氟、单氟和全氟烷基化均已得到证明，具有范围广、条件温和（氧化还原中性）和生物活性分子后期修饰的潜力。成功的关键是利用地球上丰富的廉价铁和氧化还原活性巯基硫醇催化作用，克服原料氟烷基羧酸（如三氟乙酸）极高的氧化还原潜力，使这些试剂无需预活化即可直接用作氢全氟烷基化供体。初步的机理研究支持这种合作过程的根本性质。
