(-)-Epicatechin gallate (ECg) and (-)-epigallocatechin gallate (EGCg) reduce oxacillin resistance in mecA-containing strains of Staphylococcus aureus. Their binding to staphylococcal cells is enhanced by the nongalloyl analogues (-)-epicatechin (EC) and (-)-epigallocatechin (EGC). EC and EGC significantly increased the capacity of ECg and EGCg to reduce levels of staphylococcal oxacillin resistance.
(-)-表儿茶素没食子酸酯(ECg)和(-)-表没食子儿茶素没食子酸酯(EGCg)可降低含mecA的金黄色葡萄球菌菌株对苯唑西林的耐药性。非没食子酰类似物(-)-表儿茶素(EC)和(-)-表没食子儿茶素(EGC)可增强它们与葡萄球菌细胞的结合。EC和EGC显著提高了ECg和EGCg降低葡萄球菌对苯唑西林耐药水平的能力。
