Natural and semi-synthetic antibiotics

Natural and semi-synthetic antibiotics

Natural and semisynthetic antibiotics are characterised by chemical structures with heterocyclic rings and active functional groups that inhibit the growth of microorganisms. Their structures allow them to interact with vital bacterial processes, making them useful treatments for bacterial infections. Semisynthetic antibiotics can be modified to enhance their spectrum of activity or resistance to degradation. At CymitQuimica, we offer high-quality natural and semisynthetic antibiotics for research in microbiology and pharmaceutical development.

  • Desfluoro ciprofloxacin hydrochloride
    Biosynth
    + Info

    Desfluoro ciprofloxacin hydrochloride

    CAS:
    Fluoroquinolones are a class of antibiotics that are used to treat bacterial infections. Desfluoro ciprofloxacin hydrochloride is a fluorinated derivative of ciprofloxacin and is an ultra-fast synthetic compound. It has been shown to be more potent than the parent molecule. This drug is considered to be impure because it contains other chemical compounds, such as isomers and back-pressure products. The particle size distribution of desfluoro ciprofloxacin hydrochloride is usually very broad with diameters ranging from 5 nm to 1 micron. It can be separated by particle size in a phase liquid chromatography column because the particles have different hydrodynamic diameters. Desfluoro ciprofloxacin hydrochloride can also be separated by phase chromatography on an oligosaccharide column, which produces more efficient separation than traditional high-performance liquid chromatography (HPLC).
