Melimine acetate
Based on 1 Customer Validation
Melimine acetate is an antimicrobial peptide with broad-spectrum antimicrobial activity against Gram-negative/Gram-positive bacteria, fungi and protozoa. Melimine acetate neutralizes endotoxin activity by interacting with the phosphate groups of lipid A, depolarizes and permeabilizes the cytoplasmic membrane of *Pseudomonas aeruginosa*, and induces bacterial lysis. Melimine acetate exerts additive antiviral effects against H1N1 and MHV-1 when used in combination with RK610. Melimine acetate retains its antimicrobial activity when conjugated to polymer and titanium surfaces. Melimine acetate can be used in infection-related research.

Beschreibung
In Vitro
Melimine acetate exhibits no independent antiviral activity against H1N1, MHV-1 or HSV-1; when combined with RK610, it produces an additive effect against H1N1 in MDCK cells and against MHV-1 in A9 cells, while showing no interaction against HSV-1 in Vero cells[1].
Melimine acetate exhibits high cytotoxicity against A9 cells at a concentration of 62.5 μM, and retains cytotoxicity when combined with 1.09 μM RK610; at a concentration of 31.25 μM, either used alone or in combination with 1 μM RK610, it shows no cytotoxicity against MDCK cells[1].
Melimine acetate‑modified soft contact lenses increase the adhesion inhibition rate of Pseudomonas aeruginosa ATCC 9027 and Staphylococcus aureus ATCC 6538 to 80%, and exhibit no cytotoxicity to mammalian ocular cells[2].
Melimine acetate inhibits and kills the growth of Pseudomonas aeruginosa strains 6206, 6294, Paer1 and ATCC 19660, with MIC values ranging from 66 to 132 nM and MBC values ranging from 132 to 528 nM[3].
Melimine acetate dose-dependently neutralizes LPS of Pseudomonas aeruginosa, with a neutralization rate of 71% at 1×100 MIC and 82% at 2×100 MIC[3].
Melimine (66-132 nM) acetate rapidly depolarizes the cytoplasmic membrane of Pseudomonas aeruginosa 6294 within 30 seconds; it permeabilizes the cytoplasmic membrane of Pseudomonas aeruginosa 6294, allowing Sytox Green to start entering the cells at 5 minutes; it induces concentration-dependent release of DNA/RNA from Pseudomonas aeruginosa 6294; and it lyses Pseudomonas aeruginosa 6294 in a concentration-dependent manner[3].
Melimine (66 nM; 30-150 min) acetate permeabilizes the cell membrane of Pseudomonas aeruginosa strain 6294 in 74.8% of cells within 30 minutes[3].
Melimine (66-132 nM; 2-10 min) acetate releases 75% of total cellular ATP at 66 nM and 92% of total cellular ATP at 132 nM from Pseudomonas aeruginosa 6294 within 2 minutes, while the viable cell count decreases by >3.0 log10[3].
