Neomycin sulfate is an aminoglycoside antibiotic and calcium channel protein inhibitor. Neomycin sulfate also binds to prokaryotic ribosomes inhibiting translation and is effective against gram-positive and gram-negative bacteria. Neomycin sulfate inhibits PLC (Phospholipase C) via binding to inositol phospholipids. It also inhibits phosphatidylcholine-PLD activity and induces Ca2+ mobilization and PLA2 activation in human platelets. Neomycin sulfate inhibits DNase I induced DNA degradation.
