Abstract: To find antibacterial compounds, a series of osthole ester derivatives was synthesized through three steps of oxidation, reduction, condensation reactions using osthole as the starting material. The antibacterial activities of these products were evaluated for S.aureus, E.coli and meticillin-resistant Staphylococcus aureus (MRSA) by the agar dilution method. The test results show that these derivatives have different degrees of antibacterial activities. Among them, compound Ⅲi has the most significant antibacterial activities against S.aureus and MRSA and the minimum inhibitory concentration (MIC) values are 16 mg/L, and its anti-MRSA activity is more prominent. It is worthy of further structural optimization and study.

Key words: Osthole, Ester derivative, Antibacterial activity
