Aminoglycosides - why -mycin and -micin

The aminoglycoside group includes gentamicin, amikacin, netilmicin, kanamycin, tobramycin, streptomycin, paromomycin and neomycin.

These drugs have a good action against aerobic gram-negative bacteria.

They are rapidly bactericidal. Bacterial killing is concentration dependent: The higher the concentration, the greater is the rate at which bacteria are killed.

As noted above, some of the names end by -micin while others by -mycin. The reason behind this lies in the origin of the antibiotics.

All the antibiotics ending with -mycin are either natural products or semisynthetic derivatives of compounds produced by a variety of soil actinomycetes notably Streptomyces.
Those ending with -micin are derived from other actinomycetes e.g Micromonospora.
