  • Patent number: 8664221
    Abstract: The object aims to find a novel pharmacological activity of a novel 1,2,3,4-tetrahydroquinoxaline derivative which contains, as a substituent, a phenyl group having a sulfonic acid ester structure introduced therein. A compound represented by general formula (1) or a salt thereof is useful as a glucocorticoid receptor agonist, particularly as a therapeutic agent for diseases against which a glucocorticoid receptor agonist (e.g., a steroid) is believed to be effective, such as inflammatory bone/joint diseases, inflammatory ophthalmic diseases (inflammatory ophthalmic diseases in the anterior or posterior segment of an eye).
