| Description | N-Acetyl gemifloxacin belongs to the class of organic compounds known as naphthyridine carboxylic acids and derivatives. Naphthyridine carboxylic acids and derivatives are compounds containing a naphthyridine moiety, where one of the ring atoms bears a carboxylic acid group. N-Acetyl gemifloxacin is a moderately basic compound (based on its pKa). N-Acetyl gemifloxacin is a metabolite of gemifloxacin. Gemifloxacin mesylate (trade name Factive, Oscient Pharmaceuticals) is an oral broad-spectrum quinolone antibacterial agent used in the treatment of acute bacterial exacerbation of chronic bronchitis and mild-to-moderate pneumonia. Oscient Pharmaceuticals has licensed the active ingredient from LG Life Sciences of Korea. |
