Cholesterol Synthesis Inhibitor Showing Reduction of Lipids and Hormone Antagonism

Abstract
The compound, SQ 10,591, lowered plasma cholesterol in rats fed normal or hyperlipemic diets by blocking the biosynthesis of cholesterol between mevalonate and lanosterol. It also reduced serum free fatty acids and triglycerides. In addition to its effect on lipids, SQ 10,591 inhibited the uterotrophic activity of estrogen in mice and inhibited production or release of pituitary gonadotrophins in rats. In mature female rats SQ 10,591 caused an interruption of the estrous cycle.
