According to its chemical structure, antibiotics can be divided into: quinolone antibiotics, β-lactam antibiotics, macrolides, aminoglycoside antibiotics, and the like.
According to their use, antibiotics can be divided into antibacterial antibiotics, antifungal antibiotics, antitumor antibiotics, antiviral antibiotics, animal antibiotics, agricultural antibiotics and other microbial drugs (such as ergots with pharmacologically active ergot bases). The role of contracting the uterus) and so on.
Depending on the type, there are many ways to produce antibiotics, such as biosynthesis of penicillin by microbial fermentation, sulfonamides, quinolones, etc., which can be produced by chemical synthesis; and semi-synthetic antibiotics, which are antibiotics prepared by biosynthesis. Various derivatives made by molecular structural modification by chemical, biological or biochemical methods.
Antibiotics used as antibacterial agents have the following main categories:
1. Lactam antibiotic
-Atypical β-lactam antibiotics
2. Aminoglycoside antibiotic
3. Macrolide antibiotic
4. Tetracycline antibiotic
5. Chloramphenicol (fully synthetic antibiotic)
Artificial synthetic antibiotics that are neither microbial secretions nor analogs are:
In the case of non-strictness, these two types of antibacterial agents are sometimes referred to as "antibiotics".
