Inhibitors to cell membrane synthesis are

Inhibitors to cell membrane synthesis are Polymixin, Gramicidin, and Circulin, also Tyrocidin.
Polymyxin antibiotics inhibit bacterial membranes after binding to lipopolysaccharides (LPSs), interacting with lipid A of the outer membrane, and acting as a detergent by disrupting the membrane phospholipids, causing cellular permeability and demise.
Gramicidin and circulin are antibiotic peptides that can be incorporated into the monolayers of cell membranes.
Tyrocidine is a mixture of cyclic decapeptides produced by the bacteria Bacillus brevis found in soil.
