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.
