Gentamicin C2 together with epimer C2a is a part of the antibiotic of the aminoglycoside group, gentamicin. Gentamicin C2 has a methyl group in the 6′ position. Gentamicin is a broad-spectrum antibiotic that binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria. Gentamicin is bactericidal in vitro against Gram-positive and Gram-negative bacteria.

Sisomicin is a new broad-spectrum aminoglycoside most closely related structurally to gentamicin C1a. In vitro and in experimental infections, sisomicin has been found to be more potent than or nearly as potent as the most active of the other available aminoglycosides. Although susceptible to many (but not all) aminoglycoside-inactivating enzymes, sisomicin is active against many microorganisms that are resistant to other aminoglycosides by nonenzymatic mechanisms. Sisomicin has been shown to interact synergistically with various beta-lactam antibiotics against enterococci, staphylocicci, Enterobacteriaceae, and nonfermentative gram-negative bacilli. The pharmacokinetics and toxicity of sisomicin in humans appear to be similar to those of gentamicin, despite earlier reports of greater acute toxicity in animals. Sisomicin binds to 30s and 50s ribosomal subunits of susceptible bacteria disrupting protein synthesis, thus rendering the bacterial cell membrane defective.

Gentamicin is an antibiotic of the aminoglycoside group, is derived from the growth of Micromonospora purpurea, an actinomycete. Gentamicin is a complex of three different closely related aminoglycoside sulfates, Gentamicins C1, C2, and C1a that have different patterns of methylation at the 69 position of the ring. Gentamicin C1a is a broad-spectrum antibiotic against Gram-positive and Gram-negative bacteria but may cause ear and kidney damage. Gentamicin C1a binds to the A-site RNA of the 30S bacterial ribosomal subunit. Adverse reactions include adverse renal effects, neurotoxicity (dizziness, vertigo, tinnitus, roaring in the ears, hearing loss, peripheral neuropathy or encephalopathy), respiratory depression, lethargy, confusion, depression, visual disturbances, etc.
