New retinoid chemotypes: 9-cis-Retinoic acid analogs with hydrophobic rings derived from terpenes as selective RAR agonists
摘要:
A series of 9-cis-retinoic acid analogs modified at the hydrophobic ring with a (bi)cyclohexenyl moiety derived from natural terpenes has been stereoselectively prepared using a Suzuki cross-coupling as key step. Transient transactivation studies indicate that modi. cation of the hydrophobic ring impacts dramatically on RXR-binding and transactivation, with most retinoids being inactive on RXR beta, while preserving their RAR pan-agonist pro. le. Furthermore, only the RAR gamma subtype was capable of enantiomeric discrimination with some pairs of enantiomeric terpene-retinoids. (C) 2008 Elsevier Ltd. All rights reserved.
