Pyrazole inhibitors of HMG-CoA reductase: An attempt to dramatically reduce synthetic complexity through minimal analog re-design
摘要:
An extraordinarily potent and hepatoselective class of HMG-CoA reductase inhibitors containing a pyrazole core was recently reported; however, its development was hampered by a long and difficult synthetic route. We attempted to circumvent this obstacle by preparing closely related analogs wherein the key dihydroxyheptanoic acid sidechain was tethered to the pyrazole core via an oxygen linker ('oxypyrazoles'). This minor change reduced the total number of synthetic steps from 14 to 7. Although the resulting analogs maintained much of the in vitro and cell activity of the pyrazoles, inferior in vivo activity precluded further development. Caco-2 cell permeability data suggest that enhanced cellular efflux of the oxypyrazoles relative to the pyrazoles may be responsible for the poor in vivo activity. (c) 2007 Elsevier Ltd.

[EN] Novel compounds and pharmaceutical compositions useful as hypocholesterolemic and hypolipidemic agents are described. More specifically, potent inhibitors of the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase ("HMG CoA reductase") are described. Method of using such compounds and compositions to treat subjects, including humans, suffering from hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, atherosclerosis, Alzheimer's Disease, benign prostatic hypertrophy (BPH), diabetes and osteoporosis are also described. [FR] L'invention concerne de nouveaux composés et de nouvelles compositions pharmaceutiques qui peuvent servir d'agents hypocholestérolémiants et hypolipidémiants. Cette invention se rapporte de manière plus spécifique à des inhibiteurs puissants de l'enzyme 3-hydroxy-3-méthylglutaryl-coenzyme A réductase ( HMG CoA réductase ). La présente invention concerne par ailleurs des procédés d'utilisation de ces composés et de ces compositions pour traiter des sujets, y compris des êtres humains souffrant d'hyperlipidémie, d'hypercholestérolémie, d'hypertriglycéridémie, d'athérosclérose, de la maladie d'Alzheimer, d'une hypertrophie prostatique bénigne (BPH), de diabète, et d'ostéoporose.
