Merck, P5057-5G, Paromomycin sulfate salt

General description
Chemical structure: aminoglycoside
Paromomycin or aminosidine, an aminoglycoside belongs to the class of aminoglycosides. This nonabsorbable antibiotic is found at high level in the lumen of the colon.
Application
Paromomycin sulfate salt has been used as a:
reference compound in antileishmanial activity
RNA-binding ligand and interacts with aptamer. This interaction prevents the binding (and cutting) of dicer to RNA duplex.
Recommended for use in cell culture applications at 100mg/L.
Paromomycin sulfate salt has been used as a positive control to compare the purine analog antiviral 2′,3′-dideoxyinosine (ddI).
Biochem/physiol Actions
Antimicrobial spectrum: Gram-negative and Gram-positive bacteria, some protozoan species, and limited antihelminth.
Mode of Action: Inhibits initiation and elongation during protein synthesis.
Paromomycin inhibits the initiation and elongation steps of protein synthesis by binding to 16S ribosomal RNA. Paramomycin binds to the A site, which causes defective polypeptide chains to be produced and leads to cell death.
Paromomycin possesses antileishmanial and antibacterial activities. It is used to cure visceral leishmaniasis (VL) and cutaneous leishmaniasis (CL). This aminocyclitol glycoside is active against gram-negative and gram-positive bacteria. It is also active against E. histolytica, D. fragilis and several cestodes, like Taenia saginata, Taenia solium etc.
