Cephaloglycin and its biologically active metabolite desacetylcephaloglycin
Applied Microbiology
|March 1, 1971
Summary
Cephaloglycin is converted to desacetylcephaloglycin in the body, which is responsible for treating urinary tract infections. This metabolite is active against gram-positive bacteria but less so against gram-negative ones.
Area of Science:
- Pharmacology
- Microbiology
- Drug Metabolism
Background:
- Cephaloglycin is an orally administered antibiotic.
- Understanding drug metabolism is crucial for effective therapeutic outcomes.
Purpose of the Study:
- To investigate the metabolic fate of cephaloglycin in humans.
- To determine the antibacterial activity of cephaloglycin's metabolite.
- To attribute the therapeutic success of cephaloglycin in urinary tract infections.
Main Methods:
- Chromatographic studies were employed to identify and quantify metabolites.
- Microbiological assays were used to assess antibacterial activity.
Main Results:
- Cephaloglycin is partially converted to desacetylcephaloglycin in humans after oral administration.
- Desacetylcephaloglycin exhibits equivalent antibacterial activity against gram-positive organisms compared to cephaloglycin.
- The metabolite shows reduced activity against gram-negative bacilli.
Conclusions:
- The therapeutic efficacy of cephaloglycin in urinary tract infections is primarily due to its active metabolite, desacetylcephaloglycin.
- The contribution of unaltered cephaloglycin to treatment outcomes remains undetermined.
