Geschichte
Mechanismus
Die biologische AktivitΓ€t von Spectinomycin beruht auf der Hemmung der Proteinsynthese an den Ribosomen. Es bindet an die 30S-Ribosomenuntereinheit und hemmt in Bakterien die Proteinbiosynthese.cite-ref-wirmer-4-0[4] Spectinomycin wirkt gegen grampositive und gramnegative Bakterien und wird oft dann eingesetzt, wenn penicillinresistente Keime bekΓ€mpft werden sollen.cite-ref-5[5]
Mutationen in der 16S-rRNA und dem S5-Protein der 30S-Ribosomenuntereinheit, kΓΆnnen zu einer Resistenz gegenΓΌber Spectinomycin fΓΌhren.cite-ref-kehrenberg-6-0[6]
Anwendungen
Es wird injiziert zur Behandlung von GonorrhΓΆ, besonders bei Patienten, die allergisch auf Penicillin reagieren. Ferner findet es in der Molekularbiologie Anwendung in Selektionsmedien.
