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.

  • (5E)-2,2-Dimethyl-7-[(1-naphthalenylmethyl)amino]-5-hepten-3-ynoic acid

    CAS:
    The compound (5E)-2,2-dimethyl-7-[(1-naphthalenylmethyl)amino]-5-hepten-3-ynoic acid is a chiral antifungal agent. It was developed to be used as an analytical tool for the determination of plasma concentrations and it can be used in profiling and chiral chromatography. This compound has been shown to have excellent solubility in water and good stability in most organic solvents. The compound is metabolized by the liver and excreted via the kidneys, with a half life of approximately 6 hours. The compound also shows linearity over a wide concentration range, which makes it useful for measuring quantitative changes in plasma concentrations.
