Mechanism Of Action Gramicidin D binds to and inserts itself into bacterial membranes (with a strong preference to gram-positive cell membranes) . This results in membrane disruption and permeabilization (it acts as a channel) . This leads to (i) loss of intracellular solutes (e. g. , K+ and amino acids) ; (ii) dissipation of the transmembrane potential; (iii) inhibition of respiration; (iv) a reduction in ATP pools; and (v) inhibition of DNA, RNA, and protein synthesis, which leads to cell death.
Description of the Drug: Gramicidin D is a bactericidal antibiotic used in the treatment of dermatological and ophthalmic infections.
