摘要:为了寻找抗菌候选化合物,在前期研究基础上,对蛇床子素结构进行简化与衍生,在甲醇钠/无水乙醇条
件下水解,得到(E)-2-羟基-3-异戊烯基-4-甲氧基肉桂酸(Ⅰ),中间体Ⅰ再与胺缩合制备了 17 个目标物(Ⅱa~q),

经 HNMR、 CNMR 和 MS 对目标物进行了结构确证。体外抗菌活性测试结果表明,结构简化后的衍生物呈现
较好的抗菌活性。其中,化合物Ⅱh〔(E)-3-(2-羟基-4-甲氧基-3-异戊烯基)苯基-N-(4-氟苄基)丙烯酰胺〕和Ⅱp
〔(E)-3-(2-羟基-4-甲氧基-3-异戊烯基)苯基-N-(4-三氟甲基苄基)丙烯酰胺〕的活性最为突出,前者对金黄色葡萄
球菌(S. aureus)和耐甲氧西林金黄色葡萄球菌(MRSA)的最小抑菌浓度(MIC)分别为 16 和 32 mg/L,后者
对 S. aureus 和 MRSA 的 MIC 分别为 8 和 16 mg/L,两个化合物的抗 S. aureus 活性与对照药苯唑西林较接近,
抗 MRSA 活性远优于对照药苯唑西林。

Abstract: In order to obtain compounds with antibacterial activites, intermediate (E)-2-hydroxy-3-
isopentenyl-4-methoxy cinnamic acid (Ⅰ) was firstly synthesized from hydrolysis of osthole in sodium
methoxide/anhydrous ethanol based on previous studies. Seventeen target compounds (Ⅱa~q) were then
designed and synthesized by condensation of intermediate Ⅰ with different amines, and confirmed by
1 13
HNMR, CNMR and MS. Data from in vitro antibacterial analysis showed that the derivatives with
simplified structure displayed better antibacterial performance, of which compounds Ⅱ h
[(E)-3-(2-hydroxy-4-methoxy-3-(3-methylbut-2-en-1-yl)phenyl)-N-(4-fluorobenzyl)acrylamide] and Ⅱ p
[(E)-3-(2-hydroxy-4-methoxy-3-(3-methylbut-2-en-1-yl)phenyl)-N-(4-trifluoromethylbenzyl)acrylamide]
exhibited the most prominent antibacterial activities. The minimum inhibitory concentration (MIC) of the
former to Staphylococcus aureus (S. aureus) and methicillin-resistant Staphylococcus aureus (MRSA) were
16 and 32 mg/L, respectively, while that of the latter were 8 and 16 mg/L, respectively. Both the two
compounds showed similar anti-S. aureus but enhanced anti-MRSA activity in comparison to control
oxacillin.
