Hydrogenation products of mevinolin and dihydromevinolin, a process for preparing the same and an antihypercholesterolemic pharmaceutical composition containing the same.

摘要

Hydrogenation of the natural fermentation product, mevinolin, MK-803, results in the production of dihydro- and tetra-hydro derivatives and hydrogenation of the naturally occurring dihydromevinolin results in the formation of a tetrahydro derivative. These several products with the exception of cis-(4 alpha beta , 8 alpha beta -) -tetrahydromevinolin are potent inhibitors of cholesterol biosynthesis.
