mesoionic compounds 1,4-diphenyl-5-(5-nitro-2-furanyl)-1,3,4-thiadiazolium-2-thiol chloride (MC-1) and 4-phenyl-5-(5-nitro-2-furanyl)-1,3,4-thiadiazolium-2-phenylamine chloride (MC-2) were synthesized utilizing 1,4-diphenyl-thiosemicarbazide and 5-nitro-2-furoyl chloride as starting materials. Their structures were characterized by IR, 1H-NMR, 13C-NMR and elemental analysis. These compounds were analyzed
介离子化合物 1,4-二苯基-5-(5-硝基-2-呋喃基)-1,3,4-噻二唑鎓-2-硫醇氯化物(MC-1)和 4-苯基-5-(5 -硝基-2-呋喃基)-1,3,4-噻二唑鎓-2-苯胺氯化物(MC-2)以1,4-二苯基氨基硫脲和5-硝基-2-呋喃酰氯为原料合成。它们的结构通过IR、1H-NMR、13C-NMR和元素分析表征。分析了这些化合物对诺氟沙星、四环素和红霉素(标准抗生素)对金黄色葡萄球菌耐药菌株有效性的影响。MC-1 和 MC-2 在 16 μg/mL 的亚抑制浓度下,分别有利地将四环素的抗生素活性 (MIC) 调节了 16 倍和 32 倍,将红霉素的抗菌活性调节了 4 倍。
