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.
芳基取代和芳基和(3-氧代-1-丙烯基)-取代的苯并吡喃、苯并硫吡喃、1,2-二氢喹啉和5,6-二氢萘衍生物具有视黄醇负性激素和/或拮抗剂样生物活性。发明的RAR拮抗剂可用于哺乳动物,包括人类,以预防或减轻RAR激动剂对受体位点的作用。具体而言,可以与视黄醇药物共同使用RAR激动剂,以预防或改善视黄醇或维生素A或维生素A前体引起的毒性或副作用。视黄醇负性激素可用于增强其他视黄醇和核受体激动剂的活性。例如,名为AGN 193109的视黄醇负性激素在体外转录激活实验中有效增强了其他视黄醇和类固醇激素的效果。此外,可以使用转录激活实验来鉴定具有负性激素活性的化合物。这些实验基于负性激素下调工程化嵌合视黄醇受体的构成转录激活子域的能力。
