As human and bacteria both have ribosomes, streptomycin has significant side effects in humans. At low concentrations, however, streptomycin inhibits only bacterial growth. [18] Streptomycin is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria, [19] and is therefore a useful broad-spectrum antibiotic.
Another potential mechanism is premature dissociation of the peptidyl-tRNA from the ribosome. [9] Macrolide antibiotics bind reversibly to the P site on the 50S subunit of the bacterial ribosome. This action is considered to be bacteriostatic. Macrolides are actively concentrated within leukocytes, and thus are transported into the site of ...
Gentamicin is a bactericidal antibiotic that works by binding the 30S subunit of the bacterial ribosome, negatively impacting protein synthesis. The primary mechanism of action is generally accepted to work through ablating the ability of the ribosome to discriminate on proper transfer RNA and messenger RNA interactions. [ 24 ]
The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic . Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing.
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
Skeletal formula of tetracycline with atoms and four rings numbered and labeled.. 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.

Azithromycin stands apart from other macrolide antibiotics because it is a weak inhibitor of CYP3A4, and does not significantly increase AUC value of co-administered drugs. [ 47 ] The difference in CYP3A4 inhibition by macrolides has clinical implications, for example for people who take statins , which are cholesterol -lowering drugs that are ...
Kasugamycin (Ksg) is an aminoglycoside antibiotic that was originally isolated in 1965, from Streptomyces kasugaensis, a Streptomyces strain found near the Kasuga shrine in Nara, Japan. Kasugamycin was discovered by Hamao Umezawa , who also discovered kanamycin and bleomycin , as a drug that prevent growth of a fungus causing rice blast disease .
