摘要:
The uricosuric and diuretic properties of indacrinone, [6,7-dichloro-2,3-dihydro-2-methyt-1-oxo-2-phenyl-1H-inden-5-yl)oxy]acetic acid, are carefully balanced for maximum therapeutic benefit by manipulation of the proportion of (+) and (-) enantiomers in the final product within critical limits.
摘要:
6-Phenyl-, phenalkyl- and phenylethenyl-4-hydroxytetrahydropyran-2-ones in the 4- R trans stereoisomeric forms having the structure wherein
A is H or methyl; E is a direct bond, -CH 2 -, -CH 2 -CH 2 -, -CH 2 -CH 2 -CH 2 - or-CH-CH-; and R 1 , R 2 and R 3 have several meanings, and the corresponding dihydroxy acids in which the lactone ring is hydrolytically opened, and the pharmaceutically acceptable salts of said dihydroxy acids, and the lower alkyl and the phenyl, dimethylamino or acetylamino-substituted lower alkyl esters of said dihydroxy acids; and processes for preparing them. These compounds are potent inhibitors of cholesterol synthesis by the enzyme hydroxymethyl glutaryl coenzyme A reductase.
摘要:
(+)-(4R,6S)-(E)-6-[2-(4'-fluoro-3,3',5-trimethyl-[1,1'-biphenyl]-2-yl)ethenyl]-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran-2-one of the formula and a process for preparing the same are disclosed. This compound is a very potent inhibitor of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase, a major rate limiting enzyme in cholesterol biosynthesis.
