Chemical Structure:

Neomycin is an aminoglycoside antibiotic. it consists of a mixture of Neomycin A (neamine), Neomycin B (framycetin) and Neomycin C, which differ in the side chains attached to the amino sugars. Neomycin A is a degradation product of Neomycin B and C. typically It consists of 78-88 % Neomycin B, 10-16% Neomycin C and less than 0.2% neomycin A. Neomycin is effective in vitro against Gram-positive and Gram-negative bacteria.
Neomycin sulphate belongs to a class of antibiotics known as the aminoglycosides. It is active against many Gram-positive and Gram-negative bacteria including Staph. aureus, E. coli, Klebsiella spp., H. influenzae, S. typhi, Shigella and Mycobacterium tuberculosis. It is ineffective against fungi and viruses.
Neomycin can be used to treat bacterial infections of the eye and skin infections.
