Pantetheine and pantethine esters with hypolipidemic nicotinic acid derivatives

We prepared several esters of pantetheine and pantethine, respectively, with 3-pyridineacetic acid and with 3-(3-pyridinemethoxycarbonyl)propionic acid, and we tested these products for their capacity to lower serum non-esterified fatty acids and triglycerides in normal animals. Among the products thus tested, the tetraester of pantethine with 3-(3-pyridinemethoxycarbonyl)propionic acid (MG 28362) displayed marked hypolipidemic activity, the action being of uncommonly long duration.
