plants’ essential oils, which has a broad spectrum of biological activities. In the current work, six novel β-pinene quaternary ammonium (β-PQA) salts were synthesized and evaluated in vitro for their antifungal, antibacterial and anticancer activities. The in vitro assay results revealed that compounds 4a and 4b presented remarkable antimicrobial activity against the tested fungi and bacteria. In particular
β-蒎烯是从松节油和许多其他植物精油中分离出来的单萜,具有广泛的生物活性。在目前的工作中,合成了六种新型β-蒎烯季铵( β -PQA)盐,并在体外评估了它们的抗真菌、抗菌和抗癌活性。体外测定结果表明,化合物4a和4b对测试的真菌和细菌表现出显着的抗菌活性。特别是,化合物4a对尖孢镰刀菌f.sp表现出优异的活性。 niveum 、 P. nicotianae var.nicotianae 、 R. solani 、 D. pinea和Fusicoccumaesculi, EC 50值分别为 4.50、10.92、9.45、10.82 和 6.34 μg/mL。此外,化合物4a对大肠杆菌、铜绿假单胞菌、金黄色葡萄球菌和枯草芽孢杆菌表现出最佳的抗菌作用, MIC分别为2.5、0.625、1.25和1.25 μg/mL。抗癌活性结果表明,化合物4a、4b、4c和4f对HCT-116和MCF-7细胞系表现出显着的活性,IC
