Main classifications of antibiotics

According to their chemical structure, antibiotics can be divided into quinolone antibiotics, β - lactam antibiotics, macrolides, aminoglycoside antibiotics, etc.
According to their uses, antibiotics can be divided into antibacterial antibiotics, antifungal antibiotics, anti-tumor antibiotics, antiviral antibiotics, livestock antibiotics, agricultural antibiotics, and other microbial drugs (such as ergot alkaloids produced by ergot bacteria that have pharmacological activity and have the effect of contracting the uterus).
According to their different types, antibiotics can be produced in various ways, such as penicillin being biosynthesized by microbial fermentation, sulfonamides, quinolones, etc., which can be produced by chemical synthesis methods; There are also semi synthetic antibiotics, which are various derivatives made by modifying the molecular structure of antibiotics produced by biosynthesis using chemical, biological, or biochemical methods.
