The invention describes various novel tetrazone derivatives of the formula I in which R1 and R2 are independently hydrogen, trifluoromethyl or (1-6C)alkyl (but R1 and R2 is not greater than 6 carbon atoms), or R1 is optionally substituted phenyl and R2 is hydrogen, Y is vinylene, n is 1 or 2 and m is 1, 2 or 3, or a pharmaceutically acceptable saltthereof, for use in conjunction with their pharmaceutical compositions in the treatment of various pulmonary and/or vascular disorders. Also described are various processes and intermediates for the manufacture of the novel compounds.
本发明描述了式 I 中 R1 和 R2 独立地为氢、三氟甲基或(1-6C)烷基(但 R1 和 R2 不大于 6 个碳原子),或 R1 为任选取代的苯基且 R2 为氢、Y 为亚乙烯、n 为 1 或 2 且 m 为 1、2 或 3 的各种新型四腙衍生物,或其药学上可接受的盐,用于与其药物组合物一起治疗各种肺部和/或血管疾病。此外,还介绍了制造这些新型化合物的各种工艺和中间体。
