Antibiotics of the tyrothricin complex (gramicidin and tyrocidine), which are used in some topical preparations, are cyclic peptides that bind to the cell membrane and interfere with its function. These agents possess good activity against Gram-positives, but they also bind to mammalian cell membranes and are far too toxic to be used systemically in humans.
