Gramicidin

Mechanism :

Gramicidin is a heterogeneous mixture of six antibiotic compounds divided into three categories: Gramicidin A, Gramicidin B and C, all of which are obtained from the soil bacterial species Bacillus brevis and called collectively Gramicidin D. It is used primarily as a topical antibiotic and is one of the three constituents of consumer antibiotic Neosporin Ophthalmic Solution. Its bactericidal activity is a result of increasing the permeability of the bacterial cell wall allowing inorganic cations to travel through unrestricted, thereby destroying the ion gradient between the cytoplasm and the extracellular environment.
