[C][C][=C][C][=Branch1][C][=O][O][C][=C][C][=Branch1][O][=C][Branch1][#Branch1][C][=C][Ring1][O][Ring1][=Branch1][O][O]"}, {"from": "gpt", "value": "The molecule is a hydroxycoumarin that is 4-methylcuomarin which is substituted by hydroxy groups at positions 3 and 4. A hyaluronan synthesis inhibitor. It has also been used as a fluorescent sensor to monitor the consumption of a boronic acid in Suzuki coupling reactions; fluorescence is readily detectable by the naked eye using a standard 365 nm UV lamp. It has a role as a hyaluronan synthesis inhibitor, an antioxidant and an anti-inflammatory agent."}]
