Paromomycin (sulfate)

Paromomycin (Aminosidine) sulfate, a neomycin (HY-B0470) derivative, is a broad spectrum aminoglycoside antibiotic with amebicidal and bactericidal effects. Paromomycin sulfate prematures termination of translation of mRNA and inhibits protein synthesis?by specifically binds to the RNA oligonucleotide at the A site of bacterial 30S ribosomes. Paromomycin sulfate can be used for the research of bacterial and parasitic infections^[1][2][3]. In Vitro: Paromomycin sulfate (500 μg/ml) reduces intracellular parasitic forms by 97.2% compared to control in Caco-2 cells and reduces the percentage of intracellular C. parvum forms by 99.5% in HCT-8 cells^[2].
In Vivo: Paromomycin sulfate (oral gavage; 50 mg/kg-200 mg/kg; once daily; for five consecutive days two weeks post infection) reduces the number of oocyst per gram of feces and intestine. It shows minimal focal inflammation in only 20% of the sections at 50 mg/kg from the intestines of mice infected with C. parvum and only 10% of focal inflammation at 200 mg/kg^[1].
