The compounds of Formula I, isomers, salts, pharmaceutical compositions and appliances incorporating the same, and methods of use thereof are also disclosed.
摘要:
There are provided substituted acetamide derivatives represented by general formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13, n and Z are defined in the specification. The substituted acetamide derivatives strongly inhibit acylcoenzyme A cholesterol acyltransferase (ACTA) and are expected to be effective for the treatment and prevention of hypercholesterolemia, hyperlipemia and arteriosclerosis.
