A series of isoquinoline alkaloids including tetrahydroprotoberberines, N-methyl tetrahydroprotoberberines and protoberberines were facile synthesised with protopines as the starting material. All compounds were evaluated for their antibacterial activities against four pathogenic bacteria Escherichia coli, Staphyloccocus aureus, Staphylococcus gallinarum and Salmonella choleraesuis. Experimental results
以protopines为起始原料,容易合成包括四氢小pro碱,N-甲基四氢小ber碱和小ine碱在内的一系列异喹啉生物碱。评价了所有化合物对四种病原菌大肠杆菌,金黄色葡萄球菌,鸡葡萄球菌和霍乱沙门氏菌的抗菌活性。实验结果表明,原小ber碱是被测生物碱中对靶细菌活性最高的化合物。有人提出,具有较高芳香化水平的平面分子(例如黄连5和小ber碱6))或分子的正电荷(例如N-甲基四氢小pro碱11和12)对抗菌作用具有积极影响。
