摘要:
Providing a novel tricyclic, condensed heterocyclic compound having an anti-oxidative action and being promising for use in pharmaceutical agents, cosmetics, chemical products and the like. By chemical synthesis, a novel anti-oxidative, tricyclic, condensed heterocyclic compound represented by the following formula: ##STR1## (wherein X--Y represents CH.sub.2 --C.dbd.O, CH.sub.2 --CH.sub.2 or CH.dbd.CH; Z represents O, S, or S.dbd.O; R.sub.1 to R.sub.8 represent independently those selected from the group consisting of hydrogen atom, a hydroxyl group, a halogen group, a lower alkyl group, a lower alkoxyl group, a lower alkyl ketone group and CF.sub.3 ; and at least two of R.sub.1 to R.sub.4 are hydroxyl groups); and the salts thereof are provided. The compound has an anti-oxidative activity at the same degree as or higher than the activity of .alpha.-tocopherol, so the compound is promising as a therapeutic drug for a variety of diseases, such as cancer, arteriosclerosis, or liver diseases, in which it is believed that biological lipid peroxides may be involved.
