Described are D-(threo)-1-aryl-2-acylamido-3-fluoro-1-propanols, methods for their preparation, and methods for their use as antibacterial agents. Of particular interest are D-(threo)-1-p-nitrophenyl-2-dichloroacetamido-3-fluoro-1-propanol and D-(threo)-1-p-methylsulfonylphenyl-2-dichloroacetamido-3-fluoro-1-propanol and the corresponding 2-difluoroacetamido compounds which are the 3-fluoro-3-deoxy analogs of chloramphenicol, thiamphenicol, difluoroacetyl analog of chloramphenicol, and of fluorthiamphenicol, respectively, and which are active both against organisms sensitive to and resistant to the parent amphenicol antibiotics. Other particularly valuable antibacterial agents include the corresponding 2-(chlorofluoroacetamido)-, 2-dichlorodeuterioacetamido, 2-difluorodeuterioacetamido-, and the 2-(chlorofluorodeuterioacetamido)- derivatives of the foregoing 3-fluoro-3-deoxy amphenicols.
本文介绍了D-(threo)-1-芳基-2-酰胺基-3-氟-1-丙醇的制备方法,以及它们作为抗菌剂的应用方法。特别感兴趣的是D-(threo)-1-p-硝基苯基-2-二氯乙酰胺基-3-氟-1-丙醇和D-(threo)-1-p-甲基磺酰基苯基-2-二氯乙酰胺基-3-氟-1-丙醇,以及相应的2-二氟乙酰胺衍生物,它们是氯霉素、噻氨酚、氟噻氨酚的3-氟-3-去氧类似物,对对父代氨基苯甲酰类抗生素敏感和抗性的微生物都有活性。其他特别有价值的抗菌剂包括上述3-氟-3-去氧氨基苯甲酰类化合物的相应的2-(氯氟乙酰胺)-、2-二氯代谢物、2-二氟代谢物和2-(氯氟代谢物) 衍生物。
