Synthesis and structure-activity relationships of potent retinoid X receptor ligands
摘要:
A series of potent retinoid X receptor (RXR) selective ligands was designed and prepared. The lead compound 7a showed good binding (K-i; 20-50 nM) and transactivation (EC50; 40-50 nM) to the RXR subfamily of retinoid receptors. More importantly, small variations in the geometry of the cyclopentane ring moiety led to 9, one of the most potent RXR agonists to date (K-i: 3-8 nM; EC50: 3-4 nM). (C) 1997 Elsevier Science Ltd.
Compounds of formula (I) wherein R.sup.1 -R.sup.7, R.sup.10, X and the dotted bond have the meaning given in the specification, bind selectively to retinoid RXR receptors and are useful as antiproliferative agents for dermatological and oncological indications.
The invention is novel analogs of 9-cis-retinoic acid which are useful for the treatment and prevention of coronary artery disease and to protect against premature atherosclerosis by increasing HDL levels. The invention includes processes for preparing the novel 9-cis-retinoic acid analogs.
