4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)


Protein Synthesis Inhibitors

Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins. (See all compounds classified as Protein Synthesis Inhibitors.)
