Tetracycline Antibiotics are a type of antibiotic that are used to treat a wide range of bacterial infections. They are named after their four ("tetra-") hydrocarbon rings ("-cycl-") derivation ("-ine"). They are defined as a subclass of polyketides.
Etymology
The term "tetracycline" is derived from the Greek words "tetra", meaning four, and "kuklos", meaning circle or ring. This is in reference to the four hydrocarbon rings that are a part of the tetracycline structure.
History
Tetracycline antibiotics were first discovered in the late 1940s by a team of scientists led by Benjamin Minge Duggar. The first tetracycline antibiotic, chlortetracycline, was introduced in 1948.
Mechanism of Action
Tetracycline antibiotics work by inhibiting protein synthesis in bacteria, preventing them from growing and multiplying. They do this by binding to the 30S ribosomal subunit in the bacteria, which prevents the attachment of the aminoacyl-tRNA to the RNA-ribosome complex.
Types of Tetracycline Antibiotics
There are several types of tetracycline antibiotics, including:
Uses
Tetracycline antibiotics are used to treat a variety of bacterial infections, including acne, cholera, pneumonia, Lyme disease, chlamydia, and syphilis. They are also used in the treatment of malaria when used in combination with quinine.
Side Effects
Common side effects of tetracycline antibiotics include nausea, vomiting, diarrhea, and skin rash. In rare cases, they can cause serious side effects such as liver damage, pancreatitis, and photosensitivity.
Resistance
Bacterial resistance to tetracycline antibiotics is a growing concern. This resistance can occur through several mechanisms, including decreased uptake of the drug, increased efflux, and mutation of the 30S ribosomal subunit.
