Allgemeine Beschreibung

Chemical structure: aminoglycoside

Anwendung

Paromomycin is a broad spectrum aminoglycoside antibiotic produced by Streptomyces rimosus var. paromomycinus. It has in vitro and in vivo activity similar to neomycin. It is effective against Gram-negative bacteria, Gram-positive bacteria, some protozoan species, and limited antihelminth.
It is used to study bacterial protein synthesis at the level of 16S ribosomal RNA and 30S ribosome assembly. Paromomycin is used to study cytosine-cytosine (CC) mismatch-containing RNA molecules and is used to inhibit Cryptosporidium infection of a human enterocyte cell line.

Biochem./physiol. Wirkung

Paromomycin hemmt die Initiation und Elongation der Proteinsynthese durch Bindung an 16S ribosomale RNA. Paromomycin bindet an der A-Stelle, wodurch defekte Polypeptidketten entstehen und zum Zelltod führen.
