From natural product to marketed drug: the tiacumicin odyssey

Journal Articles

Abstract

The first members of the tiacumicin family of antibiotics, encompassing more than 40 compounds, were isolated in 1975. Structurally, the core aglycon is an 18-membered macrolactone having two conjugated diene units, one isolated double bond, 5 stereogenic centers and most often, at least one glycosidic linkage. Tiacumicin B, a RNA synthesis inhibitor, is a narrow-spectrum antibiotic against clostridia. For the treatment of Clostridium difficile infection (CDI), it has the same cure rate as vancomycin but with lower relapse rate and was approved by the FDA in May 2011. The aim of this review is to present an overview of the chemistry and biology of tiacumicins since their discovery.

Antibiotic

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit growth of viruses are termed antiviral drugs or antivirals rather than antibiotics.

Broad-spectrum antibiotic

A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or when infection with multiple groups of bacteria is suspected. This is in contrast to a narrow-spectrum antibiotic, which is effective against only a specific group of bacteria.

Clostridium

Clostridium is a genus of anaerobic, Gram-positive bacteria. Species of Clostridium inhabit soils and the intestinal tract of animals, including humans. This genus includes several significant human pathogens, including the causative agents of botulism and tetanus. It also formerly included an important cause of diarrhea, Clostridioides difficile, which was reclassified into the Clostridioides genus in 2016. In the late 1700s, Germany experienced several outbreaks of an illness connected to eating specific sausages.
