Abstract
2βFuroic acid was shown to be effective in lowering both serum cholesterol and serum triglyceride levels significantly in rats with an elevation of HDL cholesterol level at 20 mg/kg/day orally. LDL receptor activity was reduced in hepatocytes, aorta foam cells, small intestinal epithelium cells and fibroblasts. HDL receptor activity was elevated in the rat hepatocytes and small intestinal cells. These activities were correlated with inhibition of acyl CoA cholesterol acyl transferase activity. Neutral cholesterol ester hydrolase activity was elevated in rat hepatocytes and human fibroblasts. Thus, 2βfuroic acid appears to interfere directly with activity of intracellular enzymes rather than affecting high affinityβmediated lipoprotein membrane receptors. In vivo treatment with 2βfuroic acid led to reduction in the liver and small intestine ATP dependent citrate lyase, acetyl CoA synthetase, acyl CoA cholesterol acyl transferase, snβglycerol 3βphosphate acyl transferase, phosphatidylate phosphohydrolase and heparin induced lipoprotein lipase activities.
2βFuroic acid reduced biliary cholesterol levels but the agent increased bile salts which are lithogenic. Acute toxicity studies in mice suggest that the agent has some hepatic toxicity effects. The LD^50^ was relatively low at 250 mg/kg IP in mice.

Sprague-Dawley rats were given 15, 70 and 140 min exposures to 15 mg/l 3,3-dimethyl-2-butanol, pinacolyl alcohol (PA), or 6-hour exposures to 0.2, 1.0 and 5.0 mg/l PA (1 mg/l = 240 ppm). A 50% mortality rate was obtained at the longest exposure to 15 mg/l. Sex related differences in the blood levels
