Aminoglycoside antibiotics act by binding to 16S rRNA. Resistance to these antibiotics occurs via drug modifications by enzymes such as aminoglycoside 6′-N-acetyltransferases (AAC(6′)s). We report here the regioselective and efficient synthesis of N-6′-ac

Truncated aminoglycoside-coenzyme A bisubstrate analogues were efficiently prepared using a convergent approach where the amine and the thiol are coupled in one pot with the addition of a linker, without the need for protecting groups. These derivatives were tested for their effect on the activity of the resistance-causing enzyme aminoglycoside 6′-N-acetyltransferase Ii, and key structure-activity relationships are reported. Moreover, one of the inhibitors is able to block aminoglycoside resistance in cells expressing this enzyme.

(Chemical Equation Presented) Complex nanomolar inhibitors in one pot: Aminoglycoside-coenzyme A derivatives were prepared through an efficient regioselective 6′-N modification of aminoglycosides (see scheme). These bisubstrates show tight-binding competi
