Aryl-substituted and aryl and (3-oxo-1-propenyl)-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.
芳基取代和芳基及(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激素和/或拮抗剂样生物活性。本发明的 RAR 拮抗剂可用于哺乳动物,包括人类,以防止或减少 RAR 激动剂对结合受体位点的作用。具体来说,RAR 激动剂可与维甲酸类药物一起给药或联合给药,以防止或改善维甲酸或维生素 A 或维生素 A 前体引起的毒性或副作用。维甲酸阴性激素可用于增强其他维甲酸和核受体激动剂的活性。例如,名为 AGN 193109 的维甲酸阴性激素能有效地
在体外转录活化试验中有效地提高了其他类视黄醇和类固醇激素的效力。此外,反式激活试验还可用于鉴定具有负性激素活性的化合物。这些检测方法基于负性激素下调具有组成型转录激活结构域的嵌合视黄醇受体活性的能力。
