CAS:Formula:C45H64O4Color and Shape:Off-White SolidMolecular weight:669.002-Methoxy-5-sulfamoylbenzoic acid
CAS:2-Methoxy-5-sulfamoylbenzoic acid (2MSBA) is a reactive compound that reacts with the proton of vancomycin to form a dianion. This reaction is reversible and can be catalyzed by chloride ions. 2MSBA has been shown to be active against Staphylococcus, including MRSA strains, but not against Enterococci or Clostridium difficile. 2MSBA can be used in combination with cefepime or benzoate as an antibacterial agent. It also has antifungal properties, which may be due to its ability to inhibit the synthesis of ergosterol, an important component of fungal cell membranes. 2-Methoxy-5-sulfamoylbenzoic acid is related to fluconazole in that it contains a benzoate moiety and an amide group. These structural features confer antibacterial and antifFormula:C8H9NO5SPurity:Min. 95%Molecular weight:231.23 g/molTabimorelin
