Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside .
Additionally, some antibiotics, such as aminoglycosides, may also exert undesired side effects on the neuromuscular junction. [ 7 ] Acetylcholinesterase inhibitors: Acetylcholinesterase inhibitors prevent the degradation of acetylcholine, subsequently increasing its concentration and duration of action in the neuromuscular junction.

Aminoglycoside-3'-phosphotransferase (APH(3')), also known as aminoglycoside kinase, is an enzyme that primarily catalyzes the addition of phosphate from ATP to the 3'-hydroxyl group of a 4,6-disubstituted aminoglycoside, such as kanamycin. [2]
Kanamycin is in the aminoglycoside family of medications. [3] It has the weakest antibacterial capabilities of all compounds in this family when used clinically, which is partially due to its increased toxicity in comparison to other aminoglycosides. [5] It works by blocking the production of proteins that are required for bacterial survival. [3]
Gentamicin is a type of aminoglycoside [5] and works by disrupting the ability of the bacteria to make proteins, which typically kills the bacteria. [5] Gentamicin is naturally produced by the bacterium Micromonospora purpurea, [9] [5] was patented in 1962, approved for medical use in 1964. [10]
Resistance to aminoglycosides is conferred via numerous mechanisms: aminoglycoside-modifying enzymes and inactivation of the aminoglycosides, which is frequently seen in both gram-positive and gram-negative bacteria and is induced by nucleotidyltransferases, phosphotransferases, or aminoglycoside acetyltransferases. reduced permeability.
Neomycin is an aminoglycoside antibiotic that displays bactericidal activity against Gram-negative aerobic bacilli and some anaerobic bacilli where resistance has not yet arisen. It is generally not effective against Gram-positive bacilli and anaerobic Gram-negative bacilli. Neomycin comes in oral and topical formulations, including creams ...
In enzymology, an aminoglycoside N6'-acetyltransferase (EC 2.3.1.82) is an enzyme that catalyzes the chemical reaction. acetyl-CoA + kanamycin-B CoA + N 6 '-acetylkanamycin-B. Thus, the two substrates of this enzyme are acetyl-CoA and kanamycin B, whereas its two products are CoA and N6'-acetylkanamycin-B.
