The bacteriostatic activity of the product and the interaction with bovine serum albumin (BSA) were tested. The results showed that the compound has good antibacterial activity against E.coli and S. aureus. The quenching mechanism of titled compound to BSA is static quenching. Moreover, at 293, 303 and 310 K, the quenching constants are 3.39×104 L/mol, 3.29×104 L/mol, 3.13×104 L/mol, respectively. The interaction of the compound to BSA is mainly driven by hydrophobic force. Meanwhile, the binding distance is 2.688 nm, and the number of binding sites is 1.049 (303 K). 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
