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 hydrochloride is available as yellow crystalline powder. Since tetracycline is absorbed into bone, it is used as a marker of bone growth for biopsies in humans. Tetracycline labeling is used to determine the amount of bone growth within a certain period of time, usually a period around 21 days.
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, a tetracyclic antibiotic. Mirtazapine, a tetracyclic antidepressant. Tetracyclics are cyclic chemical compounds that contain four fused rings of atoms, for example, Tröger's base.

The structure of tetracenomycin C was established by chemical and spectroscopic methods. [3] The three hydroxy groups, at C-4, C-4a, and C-12a, are cis to each other. The two at C-4a and C-12a are involved in intramolecular hydrogen bonding to the carbonyl oxygen atoms at C-5 and C-1, respectively.
Oxytetracycline, like other tetracyclines, is used to treat many infections, both common and rare.Its better absorption profile makes it preferable to tetracycline for moderately severe acne at a dosage of 250–500 mg four times a day for usually six to eight weeks at a time, but alternatives should be sought if no improvement occurs by three months.
Tetracene, also called naphthacene, is a polycyclic aromatic hydrocarbon.It has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes.
