designed and synthesized in a one-pot reaction in 11-76% yields. All isothiocyanates thus generated were evaluated for the first time for antibacterial activity on Pseudomonas aeruginosa and Staphylococcus aureus bacterial strains, and had satisfactory antibacterial activity in most cases. The highest activity, similar to that of reference gentamicin activity against S. aureus, was seen in compounds
34种新颖的二芳基ω-(异硫氰酸根合)烷基膦酸酯,在苯环的邻,间或对位具有氯原子和甲氧基,二甲氧基,甲硫烷基或甲氧基羰基,并具有直链烷基链(n = 2-6 )以一锅法反应设计和合成,收率为11-76%。首次评估由此产生的所有异硫氰酸酯对铜绿假单胞菌和金黄色葡萄球菌细菌菌株的抗菌活性,并且在大多数情况下具有令人满意的抗菌活性。在化合物9和13中观察到了最高的活性,类似于参考庆大霉素对金黄色葡萄球菌的活性(分别为1.5±0.1和2.5±0.2μM),而对于铜绿假单胞菌,超过一半的测试化合物被证明是比庆大霉素更有效。此外,还选择了异硫氰酸酯(9,13,
