neomycin

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.

Vineomycin A1 (OS-4742 A1) is an antibiotic effective against Gram-positive bacteria, identified in *Streptomyces matensis* subsp. vineus. It has also demonstrated antitumor activity in mice and holds potential for research in skin fibrosis.

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.
