摘要:

利用仿生合成的策略, 通过合理的药效团拼接, 将二苯醚结构单元引入3,4-二氢异喹啉母核中, 设计合成了15个新型的异喹啉衍生物; 经核磁共振波谱和高分辨质谱确定了其结构. 离体抑菌活性测试结果显示, 在50 mg/L的测试浓度下, 化合物Ic, Ie和Il对苹果轮纹病菌和小麦纹枯病菌的抑制率均超过93.0%, 优于血根碱并与百菌清相当. 化合物Il对小麦赤霉病菌的抑菌率为83.3%, 远优于血根碱(64.2%)和百菌清(57.7%). 另外, 化合物Il对5种病菌的抑制率高于血根碱.

Abstract:

Based on biomimetic synthetic strategy and reasonable pharmacophore splicing, fifteen novel isoquinoline derivatives were designed and synthesized by introducing the active fragment of diphenyl ether into the 3,4-dihydroisoquinoline skeleton. Their chemical structures were confirmed by nuclear magnetic resonance(NMR) and high resolution mass spectrometry(HRMS). In vitro antifungal activity results showed that at 50 mg/L, the inhibition rates of compounds Ic, Ie and Il against Physalospora piricola and Rhizotonia cerealis were as high as 93.0%, which were better than Sanguinarine and equivalent to Chlorothalonil. The inhibition rate of compound Il against Fusarium graminearum was 83.3%, which was much better than Sanguinarine(64.2%) and Chlorothalonil(57.7%). In addition, the inhibition rate of compound Il against five plant pathogens was higher than that of Sanguinarine.
