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. Tetracyclines are named for their four ("tetra-") hydrocarbon rings ("-cycl-") derivation ("-ine"). They are defined as a subclass of polyketides, having an octahydrotetracene-2-carboxamide skeleton and are known as derivatives of polycyclic naphthacene carboxamide. While all tetracyclines have a common structure, they differ from each other by the presence of chloride, methyl, and hydroxyl groups. These modifications do not change their broad antibacterial activity, but do affect pharmacological properties such as half-life and binding to proteins in serum. Tetracyclines were discovered in the 1940s and exhibited activity against a wide range of microorganisms including gram-positive and gram-negative bacteria, chlamydiae, mycoplasmas, rickettsiae, and protozoan parasites. Tetracyclines are among the cheapest classes of antibiotics available and have been used extensively in the prophylaxis and therapy of human and animal infections, as well as at subtherapeutic levels in animals feed as growth promoters. buy cialis kuala lumpur This image of a simple structural formula is ineligible for copyright and therefore in the public domain, because it consists entirely of information that is common property and contains no original authorship. বাংলা | čeština | Deutsch | English | español | suomi | français | עברית | italiano | 日本語 | македонски | മലയാളം | Nederlands | polski | português | português do Brasil | русский | sicilianu | svenska | ไทย | українська | 中文 | 中文（简体） | 中文（繁體） | This image of a simple structural formula is ineligible for copyright and therefore in the public domain, because it consists entirely of information that is common property and contains no original authorship. বাংলা | čeština | Deutsch | English | español | suomi | français | עברית | italiano | 日本語 | македонски | മലയാളം | Nederlands | polski | português | português do Brasil | русский | sicilianu | svenska | ไทย | українська | 中文 | 中文（简体） | 中文（繁體） | This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.
