摘要:
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.
摘要:
The present invention relates to novel, non-secosteroidal, hydroxyl substituted, carbon-linked diaryl compounds with vitamin D receptor (VDR) modulating activity that are less hypercalcemic than 1?,25 dihydroxy vitamin D3. These compounds are useful for treating bone disease and psoriasis.
摘要:
A method is provided for preventing or reducing the risk of restenosis following angioplasty by administering a retinoid, such as an RXR-selective retinoid, e.g. the compound of the formula: ##STR1## and a PPAR.gamma. specific ligand and pharmaceutically acceptable salts and esters and amides thereof.
摘要:
2,2-Dialkyl-4-aryl-substituted benzopyran and benzothiopyran derivatives of the formula ##STR1## 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 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.
摘要:
Proliferation of retinal pigment epithelium following surgery or trauma is prevented by contacting retinal pigment epithelium cells with a therapeutic amount of a retinoic acid receptor (RAR) agonist, preferably one with specific activity for retinoic acid receptors. Preferably the RAR agonist is also a potent antagonist of AP1-dependent gene expression. Alternatively, the proliferation of retinal pigment epitelium is ameliorated witha therapeutic amount of an AP-1 antagonist, alone or in combination with an RAR agonist. The drug can be administered by bolus injection into the vitreous cavity using a dosage from about 50 to 150 .mu.g, or by slow release from liposomes or an oil tamponade injected into the vitreous cavity. Formulations for preventing proliferation of retinal pigment epithelium are also provided.
