[Hypolipidemic activity of substances structurally close to penphenone in rats and mice].

Effect of substances, structurally related to penphenone (2-phenyl-3-methyl-3-hydroxypentanic acid sodium salt), was studied on the main patterns of lipid metabolism in blood of rats and mice, as well as on lipoprotein spectra of rat blood serum. All the compounds studied exhibited hypolipidemic effect, decreasing concentration of total cholesterol, cholesterol of alpha-lipoproteins and triglycerides in rat blood. The effect was less distinct in mice. 2-phenyl-3,4-dimethyl-3-hydroxypentanic acid sodium salt possessed the most pronounced hypolipidemic effect. A decrease in content of beta-and pre-beta-lipoproteins as well as of alpha-lipoproteins was observed after electrophoretic separation of blood serum lipoproteins in polyacrylamide gel in animals treated with the compound.
