    Tyrothricin

    Tyrothricin is a large cyclic polypeptide antibiotic isolated from Brevibacillus brevis. Tyrothricin is composed of a mixture of tyrocidins and gramicidins which have antimicrobial activity against Gram-positive bacteria.

    Mechanism of ActionTyrothricin targets and inserts into the gram positive membrane where it disrupts normal permeability leading to cell death. Tyrothricin is typically used topically as it would be too toxic to use systemically.
    SpectrumTyrothricin is effective against Gram positive bacteria and shows little to no effect against Gram negative bacteria.
    Molecular FormulaC65H85N11O13
