  • Patent number: 5596020
    Abstract: This invention relates to a class of novel amino bi- and tri-carbocyclic alkane compounds having bis-aryl substitution which exhibit squalene synthase inhibition properties. The bi- and tri-carbocyclic alkane ring contains an amino group and the ring is further linked or bridged to two mono- and/or bicyclic rings. Compounds of this invention reduce levels of serum cholesterol in the body without significantly reducing mevalonic metabolite synthesis. This invention relates also to pharmacological compositions and method of treatment for lowering serum cholesterol levels using the compounds of this invention.
