Macrolides belong to the polyketide class of natural products. Some macrolides have antibiotic or antifungal activity and are used as pharmaceutical drugs. Rapamycin is also a macrolide and was originally developed as an antifungal, but has since been used as an immunosuppressant drug and is being investigated as a potential longevity ...
Nitrofurantoin, sold under the brand name Macrobid among others, is an antibacterial medication of the nitrofuran class used to treat urinary tract infections (UTIs), although it is not as effective for kidney infections. [16] It is taken by mouth. [16] Common side effects include nausea, loss of appetite, diarrhea, and headaches. [16]
Lincosamides are often used clinically as an alternative antibiotic for patients who are allergic to penicillin. Of the lincosamides, clindamycin is most commonly used within the clinic due to its higher bioavailability, higher oral absorption and efficacy within the target organism spectrum. [ 23 ]
Aminoglycoside antibiotics display bactericidal activity against Gram-negative aerobes and some anaerobic bacilli where resistance has not yet arisen but generally not against Gram-positive and anaerobic Gram-negative bacteria. [3] Streptomycin is the first-in-class aminoglycoside antibiotic.
Azalides such as azithromycin are a class of macrolide antibiotics that were originally manufactured in response to the poor acid stability exhibited by original macrolides (erythromycin). [1] Following the clinical overuse of macrolides and azalides, ketolides have been developed to combat surfacing macrolide-azalide resistance among ...
During active phagocytosis, large concentrations of telithromycin is released. The concentration of telithromycin in the tissues is much higher than in plasma. Telithromycin fulfills a role that has arisen due to the rise of microbial resistance to existing macrolides and appears to be effective against macrolide-resistant Streptococcus pneumoniae.
Azithromycin is a member of macrolides that are a class of antibiotics with a cyclic structure with a lactone ring and sugar moieties. Macrolides can inhibit CYP3A4 by a mechanism called mechanism-based inhibition (MBI), which involves the formation of reactive metabolites that bind covalently and irreversibly to the enzyme, rendering it inactive.
Spiramycin is a macrolide antibiotic and antiparasitic. It is used to treat toxoplasmosis and various other infections of soft tissues.. Although used in Europe, Canada and Mexico, [1] spiramycin is still considered an experimental drug in the United States, but can sometimes be obtained by special permission from the FDA for toxoplasmosis in the first trimester of pregnancy.
