Abstract

PURPOSE:An antiarteriosclerotic that contains tritoqualine as an active ingredient, thus showing strong action to inhibit the formation of peroxidized lipids and being used for human and animals. CONSTITUTION:The objective drug contains, as an active ingredient, tritoqualine of formula I, chemical name: 7-amino-4,5,6-triethoxy-3-(5,6,7,8-tetrahydro-4-methoxy-6-methyl-1,3-d ioxolo[4,5-g]isoquinoline-5-yl phthalide or its salt, which has been clinically used as an antiallergic. The antiarterioscletrotic can be used in any forms and the dose is 0.1-100mg/kg body weight/day, usually 1-30mg/kg body weight/day. The compound of formula I is obtained by reaction of 4,5,6- triethoxy-7-nitrophthalide with contarnine of formula III in a solvent and reduction of the resultant phthalide isoquinoline with tin.

Its pharmacological mechanism of action is that lipid peroxide promotes platelet aggregation and adhesion, and that abnormal low-density lipoproteins (denatured LDL) produced by radical transfer from lipid peroxide are easily phagocytosed by macrophages. ,
It has been shown that this promotes the formation of foam cells and causes accumulation of LDL-derived cholesterol in the arterial wall.In addition, it has recently been shown that protein denaturation of endothelial cells due to lipid peroxide causes endothelial cell damage and It has been shown that it causes necrosis and sloughing (Arteriosclerosis, Vol. 5, p. 1).
