What was the first aminoglycoside?
The first aminoglycoside, the antibiotic streptomycin, was discovered in 1943 by American biochemists Selman Waksman, Albert Schatz, and Elizabeth Bugie, who isolated the compound from Streptomyces griseus, a strain of soil bacteria.
Are aminoglycosides selectively toxic?
Although aminoglycosides are clinically-essential antibiotics, the mechanisms underlying their selective toxicity to the kidney and inner ear continue to be unraveled despite more than 70 years of investigation.
What do aminoglycosides target?
Aminoglycosides are a class of clinically important antibiotics used in the treatment of infections caused by Gram-positive and Gram-negative organisms. They are bactericidal, targeting the bacterial ribosome, where they bind to the A-site and disrupt protein synthesis.
What is gentamicin most commonly used for?
Gentamicin is the most commonly used aminoglycoside antibiotic and is indicated for moderate-to-severe bacterial infections caused by sensitive agents, primarily gram negative bacteria.
