Arotinoids containing a C5,C8-diphenylnaphthalene-2-y1 ring linked to a (C3-halogenated) benzoic acid via an ethenyl connector (but not the corresponding naphthamides), which are prepared by Horner-Wadsworth-Emmons reaction of naphthaldehydes and benzylphosphonates, display the rather unusual property of being RXR agonists (15-fold induction of the RXR reporter cell line was achieved at 3- to 10-fold lower concentration than 9-cis-retinoic acid) and RAR antagonists as shown by transient transactivation studies. The binding of such bulky ligands suggests that the RXR ligand-binding domain is endowed with some degree of structural elasticity.
