2-substituted benzopyran-4-one compounds and application thereof

The invention relates to the technical field of medicine and discloses 2-substituted benzopyran-4-one compounds with a structure shown in general formula I and an application of the compounds in preparation of antifungal drugs and synergistic antifungal drugs. The compounds can be jointly used with azole antifungal drugs, can improve sensibility of drug-resistance bacteria to the azole drugs, reverses drug resistance and produces a synergistic antifungal function.

O-methylation of flavonoids by cell-free extracts of calamondin orange

Cell-free extracts of calamondin orange (Citrus mitis) catalysed the O-methylation of almost all hydroxyls of a number of flavonoids, indicating the existence in citrus tissues of ortho, meta, para and 3-O-methyltransferases. The latter, hitherto unreported enzyme, catalysed the formation of 3-O-methyl ethers of galangin and quercetin. The stepwise O-methylation of a number of compounds, especially quercetin and quercetagetin, tends to suggest a coordinated sequence of O-methylations on the surface of a multienzyme complex. The methyl acceptor abilities of the flavonoid substrates used are discussed in relation to their hydroxyl substitution patterns and their negative electron density distribution.
