  • Publication number: 20230097253
    Abstract: The present inventors have arrived at the present application by confirming that a novel quinazolinone derivative exhibits therapeutic efficacy for metabolic disorders. The quinazolinone derivative according to the present application has a similar structure to that of idelalisib, but exhibits very different properties and a different mechanism of action from idelalisib. In addition, this derivative molecule was shown to have excellent efficacy against metabolic disorders, in particular lipid metabolic disorders, through different mechanism of action. The derivative molecule also showed excellent efficacy against non-alcoholic steatohepatitis (NASH). No non-alcoholic steatohepatitis treatment drugs have been approved at the time of filing.
