▪ Tetracyclines are antimicrobial antibiotics that inhibit bacterial ribosomes which are the organelles that make proteins. Tetracyclines bind to the A-site on the 30s subunit of the bacterial ribosome which inhibits the binding of tRNAs to the mRNA-ribosome complex, and shuts down protein synthesis before it even begins.
▪ Tetracyclines are divided according to their duration of action: Short acting tetracyclines, like tetracycline itself, have a half life of around 8 hours, and long acting tetracyclines ones like doxycycline and minocycline last for 16 hours or more. Administration of tetracyclines is usually topical, or per-oral, but tigecycline is used IV only.
▪ Tetracyclines are broad spectrum, meaning they can target a wide variety of Gram positive and negative bacteria. They are often used to treat severe acne or community acquired pneumonia. It can also be given to prevent malaria, which is a parasitic protozoa that infect blood cells and hepatocytes. Both doxycycline and tigecycline are also effective against MRSA, a notoriously tough bug that resists many common antibiotics.
