title: The lipid-lowering profile in rodents. AZ-1355, a new dibenzoxazepine derivative.
abstract: The lipid-lowering profile of ethyl 10,11-dihydro-4-methoxydibenz[b,f]-(1,4)oxazepine-8-carboxylate (AZ-1355) has been evaluated using clofibrate as a reference compound. This compound is structurally unrelated to any other hypolipidemic agent. AZ-1355 was selected not only for its effect in reducing serum lipids, but also because it inhibits platelet aggregation in vivo and elevates the prostaglandin I2/thromboxane A2 ratio in vitro. It lowers serum total cholesterol in Triton-treated hyperlipidemic mice, and also lowers serum total cholesterol and triglyceride in dietary hyperlipidemic rats. In golden hamsters chosen for further evaluation, AZ-1355 reduced serum, liver and cardiac lipids, improved the beta/alpha-lipoprotein ratio and increased the HDL cholesterol. Thus, it is apparent that the lipid-lowering profile of AZ-1355 differs from that of clofibrate.
