Compounds of formula (I): ##STR1## in which: R represents hydrogen, methyl or hydroxy; X represents an alkyl, alkenyl, cycloalkyl, aryl, aralkyl, or heterocyclic group; A represents a single bond, or an alkylene, alkenylene, alkynylene or alkadienylene group; Y represents hydrogen, or an aryl, cycloalkyl or heterocyclic group; have valuable antihypercholesteremic activities and may be used in the treatment of disorders arising from a blood cholesterol imbalance in humans and other animals.

Octahydronaphthalene oxime compounds for cholesterol synthesis inhibition

Compounds of formula (I): ##STR1## (in which: R is hydrogen, methyl or hydroxy; X is alkyl, alkenyl, cycloalkyl, aryl, aralkyl, or a heterocyclic group; A is a single bond, or an alkylene, alkenylene, alkynylene or alkadienylene group; Y is hydrogen, aryl, cycloalkyl or a heterocyclic group) have the ability to inhibit the biosynthesis of cholesterol, and can thus be used for the treatment and prophylaxis of diseases relating to high blood cholesterol levels.

Octahydronaphthalene oxime derivatives for cholesterol biosynthesis

Compounds of formula (I): ##STR1## in which R is hydrogen, methyl or hydroxy; X is alkyl, alkenyl, cycloalkyl, aryl or aralkyl; A is a single bond or alkylene, alkenylene, alkynylene or alkadienylene and Y is aryl.
