生物活性

Gentamicin, an aminoglycoside antibiotic, inhibits the growth of both gram-positive and gram-negative bacteria and to inhibit several strains of mycoplasma in tissue culture. Gentamicin inhibits DNase I with an IC50 of 0.57 mM.

体外研究

Gentamicin is a more effective in vitro bacterial inhibitor than the combination of erythromycin and streptomycin. It is non-toxic to tissue cultured monolayer cells and does not inhibit virus replication.

Gentamicin has been successfully used as an additive in commercial fungal culture media to inhibit bacterial growth, and has been shown to have bactericidal effects on a wider range of microorganisms than erythromycin and streptomycin, such as Pseudomonas aeruginosa, Proteus, and Streptococcus faecalis.

Gentamicin does not interfere with the cytopathic effects of certain enteroviruses and poliovirus in tissue culture, is non-toxic to rhesus monkey kidney cells, HeLa cells, and human membrane cells, and is stable under high-pressure sterilization.

体内研究

Gentamicin (10 mg/kg; subcutaneous injection; Once every 12 hours, for a total of 6 times, can improve the survival rate and alter the inflammatory response of a small model of Pseudomonas aeruginosa sepsis.

Animal Model: FVB/N mice (6-10-week-old; ~20 g) received an intratracheal injection of a solution containing the ATCC 27853 strain of P. aeruginosa.
Dosage: 10 mg/kg
Administration: Subcutaneous injection (s.c.); every 12 h for a total of six doses
Result: Survival at 7 days was 100% for mice. Down-regulated the proinflammatory cytokines, IL6.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
