The present invention is directed to phenylalkylthienylalkanoic acids and related compounds having a mercaptoalkanoic acid substituent. These compounds are useful in the treatment of bronchial asthma and they are obtained by the reaction of an appropriate epoxy compound with a mercapto alkanoic acid. Both reactants in this process are used as the ester so that the reaction gives a diester which is then hydrolyzed to the corresponding free acids by standard procedures.
本发明涉及苯基烷基
噻吩基烷酸及具有巯基烷酸取代基的相关化合物。这些化合物可用于治疗支气管哮喘,它们是通过适当的环氧化合物与巯基烷酸反应得到的。在这一过程中,两种反应物都用作酯,因此反应生成二酯,然后通过标准程序
水解成相应的
游离酸。
