Skeletal formula of tetracycline with atoms and four rings numbered and labeled.. Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of Streptomyces bacteria or produced semi-synthetically from those isolated compounds. [1]
Tetracycline, sold under various brand names, is an antibiotic in the tetracyclines family of medications, used to treat a number of infections, [3] including acne, cholera, brucellosis, plague, malaria, and syphilis. [3]
The following is a list of antibiotics. ... Similar structure with tetracycline, but five times stronger, big volume distribution and long half-time in the body
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
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.
Doxycycline is a broad-spectrum antibiotic of the tetracycline class used in the treatment of infections caused by bacteria and certain parasites. [1] It is used to treat bacterial pneumonia, acne, chlamydia infections, Lyme disease, cholera, typhus, and syphilis. [1]
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 ...
Minocycline, sold under the brand name Minocin among others, is a tetracycline antibiotic medication used to treat a number of bacterial infections such as some occurring in certain forms of pneumonia. [2] [4] [7] It is generally (but not always) less preferred than the tetracycline doxycycline.
