Lipophilic substituents at benzodioxane C (7) of 3-(benzodioxan-2-ylmethoxy)-2,6-difluorobenzamide improve the antibacterial activity against methicillin-resistant Staphylococcus aureus strains to MIC values in the range of 0.2–2.5 μg/mL, whereas hydrophilic substituents at the same position and modifications at the benzodioxane substructure, excepting for replacement with 2-cromanyl, are deleterious
3-(苯并二恶烷-2-基甲氧基)-2,6-二氟苯甲酰胺的苯并二恶烷C(7)上的亲脂取代基可提高对耐甲氧西林金黄色葡萄球菌菌株的抗菌活性,使其MIC值在0.2–2.5μg/ mL的范围内,而除了被2-cromanyl取代外,在相同位置的亲水取代基和在苯并二恶烷亚结构上的修饰是有害的。一些铅化合物还表现出良好的抗Mtb活性。与众所周知的FtsZ抑制剂3-(2-苯并噻唑-2-基甲氧基)-2,6-二氟苯甲酰胺的SAR平行,以及FtsZ抑制的典型细胞改变表明这种蛋白质是这些有效的抗菌苯并二恶烷-苯甲酰胺的靶标。
