phosphonium salts on the basis of pyridoxine derivatives were synthesized and their antibacterial activity against clinically relevant strains was tested in vitro. All compounds were almost inactive against gram-negative bacteria and exhibited structure-dependent activity against gram-positive bacteria. A crucial role of ketal protection group in phosphonium salts for their antibacterial properties
在吡x嗪衍生物的基础上合成了13种phospho盐,并在体外测试了它们对临床相关菌株的抗菌活性。所有化合物对革兰氏阴性菌几乎没有活性,对革兰氏阳性菌表现出结构依赖性活性。已证明了缩酮保护基在phospho盐中的抗菌特性至关重要。在合成的化合物中,发现5,6-双[三苯基膦基(甲基)]-2,2,8-三甲基-4 H- [1,3]二氧杂[4,5- c ]吡啶二氯化物(化合物20)是对金黄色葡萄球菌和表皮葡萄球菌最有效菌株(MIC 5μg/ ml)。该化合物的抗菌活性机制可能涉及细胞渗透以及与基因组和质粒DNA的相互作用。
