Biological Activity

Aminoglycoside |
Apramycin (4 mg/L) sulfate inhibits 99% of K. pneumoniae and 93% of Enterobacter clinical isolates. Apramycin (8 mg/L) sulfate inhibits 99% of all E. coli, 98% of C. freundii, 96% of Providencia spp., 92% of S. marcescens, 97% of M. morganii and 100% of P. mirabilis clinical isolates, exhibiting significantly better antimicrobial activity than the clinical standard-of-care aminoglycosides Gentamicin and Amikacin sulfate[1].
Apramycin (100 μM, 10 min) sulfate exerts an 11% decrease in cytoplasmic uptake of E.coli when lowering the pH from 7.3 to 5.7 while the amounts of Gentamicin and Amikacin are reduced by 62% and 51%, respectively[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Apramycin (16, 32, 80 mg/kg, s.c., 24 h) sulfate dose-dependently reduces bacterial burden in the kidneys between 2-5 log10 and in blood between 2-3 log10 for neutropenic model of Staphylococcus aureus septicemia mice[2].
Apramycin (50 mg/kg/d, s.c., 21 d) sulfate induces nephrotoxicity scores comparable to those induced by Gentamicin (10 mg/kg/d)[3].
