Gentamycin-sulfate

Gentamycin-sulfate is an aminoglycoside antibiotic and a metabolic product of Micromonospora purpurea. It is a mixture (C_19-21H_39-43N₅O₇x2.5H₂SO₄, MW 694.75-723.75) of 3 closely related components: C₁ (approx. 20-40 %), C₂ (approx. 40-60 %), and C_1a (approx. 10-30 %). Gentamycin is active against Gram-positive and Gram-negative bacteria and Mycoplasma.

mechanism: Inhibits protein biosynthesis by binding to the 30 S ribosomal subunit and by destroying the cell membrane.
