Lactones of formula ##STR1## and their pharmacologically acceptable salts endowed with antioxiding and hypolipidaemic properties and that show the capability to prevent and/or to delay the oxidative modification of the lipoproteins by competing with the chain of propagation of the lipidic peroxidation by means of an effective scavenging of the peroxylic radicals. The compounds object of the present invention are useful in the treatment of the atherosclerosis and of many correlated vascular pathologies, like ischaemic cardiopathies (angina pectoris and myocardial infarction), cerebral thrombosis and peripheral arteriopathies, because the high plasma levels of lipids and the oxidative modifications of the low density lipoproteins (LDL) represent crucial events in the pathogenesis of the atherosclerosis.
化学式为##STR1##的内酯及其具有抗氧化和降脂作用的药用可接受盐,具有防止和/或延迟脂质过氧化的能力,通过有效清除过氧自由基与脂质过氧化的传播链竞争。本发明的化合物可用于治疗动脉粥样硬化及许多相关的血管病理,如缺血性心脏病(心绞痛和心肌梗塞)、脑血栓形成和外周动脉病变,因为高血浆脂质
水平和低密度脂蛋白(LDL)的氧化修饰在动脉粥样硬化的发病机制中起着关键作用。
