Indane derivatives and their salts represented by the general formula (1), ##STR1## wherein R.sup.1 is an amino group which may have lower alkyl groups as the substituents, a hydroxylimino group, an alkanoylamino group having 1 to 10 carbon atoms which may have halogen atoms as the substituents, a lower alkylsulfonylamino group, a phenylsulfonylamino group which may have lower alkyl groups as the substituents on the phenyl ring, a benzoylamino group having lower alkyl groups as the substituents on the phenyl ring, and a phenyl-lower alkylamino group having a hydroxyl groups or a lower alkyl groups as the substituents on the phenyl ring, R.sup.2 is a hydrogen atom, a lower alkyl group, a halogen atom, a nitro group, an amino group, an amino-lower alkyl group, a lower alkanoylamino group, a lower alkanoylamino-lower alkyl group which may have halogen atoms as the substituents, a lower alkylthio group, a 1-piperidinesulfonyl group, or a lower alkenyl group; R.sup.3 is a hydrogen atom, a lower alkyl group, or a halogen atom; R.sup.4 and R.sup.5 are the same or different from each other, and are each a hydrogen atom, or a lower alkyl group; provided that when R.sup.1 is a hydroxylimino group, then R.sup.2 and R.sup.3 should not be hydrogen atoms at the same time. The indane derivatives and their salts are useful as preventive and curative agents for various diseases and disorders caused by the excessive formation and accumulation of the active oxygen radicals and the peroxidized substances in the living body, and/or the defects of phylaxis mechanisms of the living body, for example anti-arreriosclerotic agents, carcinogenesis preventive agents, carcinostatic agents, anti-inflammatory agents, analgesics, autoimmune disease curative agents, platelets aggregation inhibitory agents, hypotensive agents, anti-hyperlipemic agents, retinosis of immature infant and cataract preventive and curative agents. The indane derivatives and their salts are also useful as antioxidants for oils and fats being contained in processed foods.
Indane衍生物及其盐用通式(1)表示,其中R.sup.1是氨基团,可能具有较低的烷基基团作为取代基,羟基亚胺基团,具有1至10个碳原子的烷酰胺基团,可能具有卤素原子作为取代基,较低的烷基磺酰胺基团,苯基磺酰胺基团,可能具有苯环上的较低烷基基团作为取代基,苯基烷酰胺基团,在苯环上具有较低烷基基团作为取代基,以及苯基较低烷基氨基基团,在苯环上具有羟基或较低烷基基团作为取代基,R.sup.2是氢原子,较低烷基基团,卤素原子,硝基基团,氨基团,氨基较低烷基基团,较低烷酰胺基团,可能具有卤素原子作为取代基,较低烷基硫基团,1-哌啶磺酰基团或较低烯基基团;R.sup.3是氢原子,较低烷基基团或卤素原子;R.sup.4和R.sup.5相同或不同,均为氢原子或较低烷基基团;但是当R.sup.1是羟基亚胺基团时,R.sup.2和R.sup.3不能同时为氢原子。Indane衍生物及其盐可用作预防和治疗各种疾病和障碍的药物,这些疾病和障碍是由于活性氧自由基和过氧化物在生体内的过度形成和积累以及生体免疫机制的缺陷而引起的,例如抗动脉粥样硬化药物,癌症预防剂,抗癌剂,抗炎剂,止痛剂,自身免疫疾病治疗剂,血小板聚集抑制剂,降压剂,降血脂剂,未成熟婴儿视网膜病和白内障预防和治疗剂。Indane衍生物及其盐也可用作加工食品中含有的油脂的抗氧化剂。
