Gentamicin C1 sulfate is one of several components of the gentamicin C complex. Gentamicin C1 can comprise 25-50% gentamicin depending on the manufacturer or manufacturing process. The gentamicin C complex comprises approximately 80% gentamicin and exhibits the most potent antimicrobial activity. The higher antimicrobial activity of the group C gentamicins is thought to arise from the lack of hydroxy groups on the 3’ and 4’ positions of the purpurosamine (2-amino-hexose) fragments. Gentamicin C1 differs from gentamicin C1a by a methyl group in the 6’ position of the purpurosamine (2-amino-hexose) ring. Gentamicin C1 sulfate, EvoPure® is ≥95.0% gentamicin C1.

Caldwell et al. used gentamicin C1 sulfate from TOKU-E to study aminoglycoside binding sites of APH-GMPPNP and APH-GTP crystals. "Antibiotic Binding Drives Catalytic Activation of Aminoglycoside Kinase APH(2″)-Ia."  

    CAS Number


    Molecular Formula

    C21H43N5O· xH2SO4 (lot specific)

    Molecular Weight

    477.59 g/mol (Free base)

    Mechanism of Action

    Aminoglycosides target the 30S ribosomal subunit resulting in an inability to read mRNA ultimately producing a faulty or nonexistent protein.
