Abstract

L'invention concerne des quinoléines substituées de la formule (I). Ces quinoléines, puissants inhibiteurs de la protéine de transfert d'ester de cholestérol, stimulent le transport inverse du cholestérol. Les principes actifs de l'invention provoquent une baisse du niveau de cholestérol LDL dans le sang et une augmentation équivalente du niveau de cholestérol HDL. Ces quinoléines substituées peuvent être utilisées dans le traitement et la prévention de l'hyperlipoproteinémie, l'hypolipoprotéinémie, la dyslipidémie, l'hypertriglycéridémie, l'hyperlipidémie combinée ou l'artériosclérose.
