New retinoid chemotypes: 9-cis-retinoic acid analogs with hydrophobic rings derived from terpenes as selective RAR agonists

Bioorg Med Chem. 2008 Nov 15;16(22):9719-28. doi: 10.1016/j.bmc.2008.09.069. Epub 2008 Oct 2.

Abstract

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 modification of the hydrophobic ring impacts dramatically on RXR-binding and transactivation, with most retinoids being inactive on RXRbeta, while preserving their RAR pan-agonist profile. Furthermore, only the RARgamma subtype was capable of enantiomeric discrimination with some pairs of enantiomeric terpene-retinoids.
