Indole derivatives characterized by having a 1,3,4,9-tetrahydropyrano[3,4-b]indole-1-acetic acid nucleus bearing a substituent in position 1 and 4. The nucleus may be optionally substituted at position 8. The derivatives are useful anti-inflammatory and analgesic agents and methods and chemical intermediates for their preparation are also disclosed. Included are compounds of the formula ##STR1## wherein R.sup.1 is --H or lower alkyl containing 1 to 3 carbon atoms; R.sup.2 is --NH.sub.2, --NHCHO, --NHCONH.sub.2, --OCH.sub.3, oxo; R.sup.3 is --H or lower alkyl containing 1 to 3 carbon atoms and the pharmaceutically acceptable salts thereof when R.sup.1 is --H.
这是一篇化学专业的文章,介绍了一类以1,3,4,9-四氢吡喃[3,4-b]吲哚-1-乙酸核为特征的吲哚衍生物。该核带有1和4位置的取代基,并且8位置可以选择性地被取代。这些衍生物是有用的抗炎和镇痛剂,同时还公开了它们的制备方法和化学中间体。其中包括公式为##STR1##的化合物,其中R1为--H或含有1到3个碳原子的低碳基;R2为--NH2、--NHCHO、--NHCONH2、--OCH3、氧代;R3为--H或含有1到3个碳原子的低碳基,当R1为--H时,还包括其药学上可接受的盐。
