Several additional targets for antibiotics in human cells have been identified like interaction of fluoroquinolones with DNA damage repair in eukaryotes, or inhibition of mucin overproduction by oxazolidinones. Conclusion The effects of antibiotics on eukaryotes are due to identical mechanisms as their ...
Prokaryotes and eukaryotes (80S) have a different structure to ribosomes so can use antibiotics for selective toxicity against ribosomes of prokaryotes (70S) Mechanism of Action INHIBITION OF PROTEIN SYNTHESIS (cont’d) Aminoglycosides bind to bacterial ribosome on 30S subunit; and blocks formation o...

whereas ribosomes isolated from archaea or eukaryotic cytoplasmic ribosomes are resistant [243,244,245,246]. If read-through in eukaryotes is due to an interference with mitochondrial functions only has not been addressed. Nevertheless, a clinical...
