Aryl-substituted and aryl and (3-oxo-1-propenly)-substituted benzopyran, benzothiopyran, 1,2-dihydroquinoline, and 5,6-dihydronaphthalene derivatives have retinoid negative hormone and/or antagonist-like biological activities. The invented RAR antagonists can be administered to mammals, including humans, for the purpose of preventing or diminishing action of RAR agonists on the bound receptor sites. Specifically, the RAR agonists are administered or coadministered with retinoid drugs to prevent or ameliorate toxicity or side effects caused by retinoids or vitamin A or vitamin A precursors. The retinoid negative hormones can be used to potentiate the activities of other retinoids and nuclear receptor agonists. For example, the retinoid negative hormone called AGN 193109 effectively increased the effectiveness of other retinoids and steroid hormones in in vitro transactivation assays. Additionally, transactivation assays can be used to identify compounds having negative hormone activity. These assays are based on the ability of negative hormones to down-regulate the activity of chimeric retinoid receptors engineered to possess a constitutive transcription activator domain.

(EN) 2,2-Dialkyl- 4-aryl-substituted benzopyran and benzothiopyran derivatives of formula (I) where the symbols have the meaning described in the specification, have retinoid negative hormone and/or antagonist-like biological activities. The invented RAR antagonists can be administered to mammals, including humans, for the purpose of preventing or diminishing action or RAR agonists on the bound receptor sites. Specifically, the RAR agonists are administered or coadministered with retinoid drugs to prevent or ameliorate toxicity or side effects caused by retinoids or vitamin A or vitamin A precursors. The retinoid negative hormones can be used to potentiate the activities of other retinoids and nuclear receptor agonists.(FR) L'invention concerne des dérivés de 2,2-dialkyl-benzopyrane et benzothiopyrane à substitution 4-aryl de formule (I), dont les symboles sont définis dans le descriptif. Ces dérivés présentent des activités biologiques rétinoïdes de type antagonistes et/ou hormones négatives. Les antagonistes de RAR de l'invention peuvent être administrés aux mammifères, y compris aux humains, pour prévenir ou réduire l'action d'antagonistes de RAR sur les sites récepteurs liés. En particulier, les agonistes de RAR sont administrés ou co-administrés avec des médicaments rétinoïdes pour empêcher ou atténuer la toxicité ou les effets secondaires des rétinoïdes, de la vitamine A ou des précurseurs de la vitamine A. Les hormones négatives rétinoïdes peuvent être utilisées pour renforcer les activités d'autres rétinoïdes et celles d'agonistes de récepteurs nucléaires.
