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.

Ceftazidime t-butyl ester
CAS:Ceftazidime t-butyl ester is a prodrug of ceftazidime. It is a crystalline, stable form of the drug that can be dissolved in an organic solvent. Ceftazidime t-butyl ester has an average UV detection wavelength with a linear range of 200-600 nm and can be detected at a wavelength of 220 nm. This drug is used to treat infections caused by bacteria, including those that are resistant to other antibiotics, such as penicillin or ampicillin. Ceftazidime t-butyl ester has been shown to be effective against methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium perfringens, although is not active against acid-fast bacteria such as Mycobacterium tuberculosis or Mycobacterium avium complex.Formula:C26H30N6O7S2Purity:Min. 95%Molecular weight:602.68 g/molN-Demethyl-N-(ethylsuccinyl) erythromycin
