Neomycin (CAS NO.1404-04-2) was discovered in 1949 by the microbiologist Selman Waksman and his student Hubert Lechevalier at Rutgers University. It is produced naturally by the bacterium .

  Neomycin (CAS NO.1404-04-2) is reported in EPA TSCA Inventory.

The Neomycin, with the CAS registry number 1404-04-2, is also known as Bykomycin. It's classification codes are Anti-Bacterial Agents; Anti-Infective Agents; Drug / Therapeutic Agent; Enzyme Inhibitors; Human Data; Mutation Data; Natural Product; Protein Synthesis Inhibitors. This chemical's molecular formula is C₂₃H₄₆N₆O₁₃ and molecular weight is 614.31. What's more, its systematic name is called (1R,2R,3S,4R,6S)-4,6-Diamino-2-{[3-O-(2,6-diamino-2,6-dideoxy-β-L-idopyranosyl)-β-D-ribofuranosyl]oxy}-3-hydroxycyclohexyl 2,6-diamino-2,6-dideoxy-α-D-glucopyranoside. Neomycin is an aminoglycoside antibiotic found in many topical medications such as creams, ointments, and eyedrops. Neomycin is overwhelmingly used as a topical preparation, such as Neosporin. This chemical can also be given oraly, where it is usually combined with other antibiotics. It has also been used to treat small intestinal bacterial overgrowth.
