Abstract: A series of 4-phenoxy quinoline-based mevalonolactone derivatives have been synthesized and evaluated as 3-hydroxy-3-methylglutaryl CoA reductase (HMG CoA reductase) inhibitors. One member of this series, (4R,6S)-6-{(E)-2-[6-fluoro-7-chloro-4-(4-fluorophenoxy-quinoline)-3-yl-]-ethenyl}-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran-2-one (3d), showed more potent activity than rosuvastatin or pitavastatin to inhibit the rat HMG CoA reductase in vitro. This compound was selected for the extensive preclinical development as a potential hypocholesterolemic candidate.

Key words: HMG CoA reductase inhibitors, 4-Phenoxy quinolines, Synthesis
