The effect of CH-123 (3-carbethoxy-6-methyl-1-9-(carboxy-methyl)-1-4-oxo-6,7,8,9-tetrahydro-4H-pyrid o(1,2a)pyrimidine) was investigated on the activity of 4 lysosomal enzymes: beta-glucuronidase, beta-galactosidase, N-acetyl-beta-glucosaminidase and acid phosphatase obtained from aortic smooth muscle and liver cells of rabbits. Animals were fed on a 2% cholesterol diet for 4 weeks and used an experimental atherosclerotic group. In drug-treated groups, after 4 weeks of cholesterol feeding the diet was changed to regular food and the animals were treated daily either with 50 mg/kg CH-123 or with 250 mg/kg Clofibrate.
