Gramicidin S
Based on 1 publication(s) in Google Scholar
Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na+/K+-ATPase, tobacco leaf plasma membrane Mg2+/K+-ATPase, and rat heart plasma membrane Ca2+-ATPase, respectively.

In the membrane protein localization experiment, Gramicidin S (1 μM; 10 min) causes the localization disorder of the peripheral membrane proteins MinD, DivIVA and PlsX of Bacillus subtilis, among which PlsX completely lost its membrane binding ability[1].
In the cell viability experiment, Gramicidin S (1 μM; 30 min) significantly reduces the viability of Escherichia coli (E. coli) cells, causing about 70% cell death by destroying the cell membrane integrity and inducing lipid phase separation[1].
Gramicidin S has nematicidal activity with IC50=0.08 μM (Bursaphelenchus lignicolus) and inhibits Escherichia coli with IC50=3.5 μM[1].
Gramicidin S (1 μg/mL, 2 μg/mL; 9 h) can induce fluid lipid domains independently of the MreB cytoskeleton, leading to the delocalization of peripheral membrane proteins (such as MurG involved in cell wall synthesis)[2].

Result:Significantly reduced cell viability, with a 70% decrease in viable cell count compared to the control group.
Disrupted the bacterial membrane by inserting hydrophobic residues into the phospholipid bilayer, inducing lipid phase separation and fluid membrane microdomain formation, which ultimately led to membrane permeability loss and cell death.
Gramicidin S (20-50 μg/mouse/day; intraperitoneal injection; daily; 16 days) shows a 60% tumor inhibition rate in BALB/c mice subcutaneously implanted with Meth A fibrosarcoma at the high dose (50 μg/mouse/day) after 16 days, while low-dose treatment exhibits weaker inhibition[3].

Animal Model:Female ICR mice (8 weeks old,) subcutaneously implanted with Sarcoma 180 (S180)[3]
-
Dosage:0 (control), 20 μg/mouse/day, 200 μg/mouse/day (dissolved in ethanol and diluted with Dulbecco's PBS)
-
Administration:Intraperitoneal injection daily for 21 days starting from day 1 after tumor inoculation
-
Result:On day 21, the high-dose group (200 μg/mouse/day) showed a 60% tumor growth inhibition rate, with a slight increase in body weight, similar to the control group.
No significant difference in survival rate was observed among groups, with 6/8 mice surviving in both the high-dose and control groups.
