The mechanism of action for the antibacterial effect of tetracyclines relies on disrupting protein translation in bacteria, thereby damaging the ability of microbes to grow and repair; however protein translation is also disrupted in eukaryotic mitochondria leading to effects that may confound experimental results.

The overall structure of TetR can be broken down into two DNA-binding domains (one per monomer) and a regulatory core, which is responsible for tetracycline recognition and dimerization. TetR dimerizes by making hydrophobic contacts within the regulatory core. There is a binding cavity for tetracycline in the outer helices of the regulatory domain.
Glycylcycline antibiotics have a similar mechanism of action as tetracycline antibiotics. They block protein synthesis hence preventing bacterial reproduction. Both classes of antibiotics bind to the 30S ribosomal subunit to prevent the amino-acyl tRNA from binding to the A site of the ribosome. However, the glycylcyclines appear to bind more ...
Minocycline was a commonly used tetracycline synthesized in Lederle Laboratories in 1970, but antibiotic resistance to the drug began growing in prevalence throughout the 70's and 80's. [30] [31] While the problem of antibiotic resistance was known to scientists during the 1980s, apathy led to little federal attention given to the emerging ...
Chlortetracycline (trade name Aureomycin, Lederle Laboratories) is a tetracycline antibiotic, the first tetracycline to be identified. It was discovered in 1945 at Lederle Laboratories under the supervision of scientist Yellapragada Subbarow and Benjamin Minge Duggar.
Tetracyclines are antibiotics that also exhibit MMP inhibitory activity. They chelate Zn 2+ ion, thereby inhibiting MMP activity. It is believed that tetracyclines also effect MMP expression and proteolytic activity. [16] Doxycycline. Doxycycline is a semi-synthetic tetracycline that has been studied for dental and medical
