Hypolipidemic activity of 4-pyrimidinecarboxylic acids in CF1 mice

A series of 4-pyrimidinecarboxylic acids were evaluated for hypolipidemic activity in mice at 20-30 mg/kg/d ip. A number of these derivatives were observed to be active at this dose. Substitution of the hydroxyl group in position 2 and 6 of the 4-pyrimidinecarboxylic acid with a sulfhydryl and an amino group, respectively, led to a compound which produced a greater than 40% reduction of serum cholesterol and triglyceride levels in mice. Similarly, a compound which was substituted with an amino group in position 2 and an isobutyl group in position 5 led to equally potent activity as a hypolipidemic agent.
