In search of potent antifungal agents derived from natural product 3-carene, 19 novel (Z)-3-caren-5-one oxime ethers 3a–3s were synthesized by multi-step reaction and characterized by UV–Vis, IR, NMR, ESI–MS and elemental analysis. The in vitro antifungal activity of all the target compounds was preliminarily evaluated, and the test results indicated that some of the target compounds displayed excellent
为了寻找源自天然产物 3-蒈烯的强效抗真菌剂,通过多步反应合成了19 种新型 ( Z )-3-蒈烯-5-酮肟醚3a-3s ,并通过 UV-Vis、IR、NMR、 ESI-MS 和元素分析。对所有目标化合物的体外抗真菌活性进行了初步评价,试验结果表明部分目标化合物对R. Solani表现出优异的抑制活性。例如,化合物3b (R = 2 ' -CH 3 )、3c (R = 3 ' -CH 3 ) 和3i对R. Solani的抑制百分比(R = 3 ' -Cl) 分别为 98.4、93.7 和 94.9%,优于或与阳性对照百菌清相当。还进行了计算模拟研究以阐明标题化合物的构效关系 (SAR)。首先,利用CoMFA方法建立了一个有效合理的3D-QSAR模型,对标题化合物的优化具有重要意义。此外,DFT计算发现3-蒈烯部分和肟醚基团都是化合物3b的潜在药效团,具有最好的抗真菌活性。同时,通过分子对接
