neomycin sulfate

Neomycin sulfate (Framycin sulfate) is a broad-spectrum aminoglycoside antibiotic that blocks the synthesis of bacterial proteins in order to exert antimicrobial activity. Neomycin sulfate is commonly used to screen prokaryotic and eukaryotic cells for Neo resistance genes.

Neomycin sulfate (Standard) is the certified analytical reference standard of Neomycin sulfate developed for quantitative analysis, quality control, and biochemical research applications, and as a broad-spectrum aminoglycoside antibiotic, Neomycin sulfate (Framycin sulfate) inhibits bacterial protein synthesis by binding ribosomal subunits, while being widely applied as a selective agent for screening prokaryotic and eukaryotic cells harboring Neo resistance genes.

Paromomycin binds specifically to the RNA oligonucleotide at the A site of bacterial 30S ribosomes, thereby causing misreading and premature termination of translation of mRNA and inhibition of protein synthesis followed by cell death. Paromomycin Sulfate (Aminosidine sulfate) is the sulfate salt form of paromomycin, a structural derivative of neomycin, an aminoglycoside antibiotic with amebicidal and bactericidal effects against predominantly aerobic gram-negative bacteria.

Framycetin sulfate (Neomycin Sulphate B) belongs to aminoglycoside class of antibiotics that contain two or more aminosugars connected by glycosidic bonds.

Paromomycin (Sulfate Salt) is an aminoglycoside that is active against Gram-negative and many Gram-positive bacteria as well as some protozoa and cestodes. Paromomycin in combination with sodium stibogluconate has proven to be effective in African and Indian VL (visceral leishmaniasis) and improves survival in African VL[3]. PS (Paromomycin Sulfate) is effective for elimination of B. coli without hematological side effects[4]. The activity of phosphoglucose isomerase was slightly inhibited by 10(-3) M paromomycin sulfate while those of hexokinase, phosphofructokinase and glucose-6-phosphate dehydrogenase were not inhibited[5]. In addition, with regard to correlation of endotoxemia with renal impairment, endogenous creatinine clearance and p-aminohippurate clearance were significantly improved (P less than 0.02) in those patients whose endotoxemia disappeared on paromomycin sulfate administration. Paromomycin sulfate seems to be effective in the prevention of endotoxemia and the associated renal impairment in cirrhosis in man[6]. Significantly higher frequencies of resistance to paromomycin, kanamycin, neomycin and tobramycin were observed in S. aureus isolates from PS (paromomycin supplemented) birds. Paromomycin supplementation resulted in resistance to aminoglycosides in bacteria of PS turkeys. Co-selection for resistance to other antimicrobial agents was observed in E. coli isolates[7].
