Synthesis and use of sulfonamide-, sulfoxide-, or sulfone-containing aminoglycoside–CoA bisubstrates as mechanistic probes for aminoglycoside N-6′-acetyltransferase
Aminoglycoside-coenzyme A conjugates are challenging synthetic targets because of the wealth of functional groups and high polarity of the starting materials. We previously reported a one-pot synthesis of amide-linked aminoglycoside-CoA bisubstrates. These molecules are nanomolar inhibitors of aminoglycoside N-6'-acetyltransferase Ii (AAC(6')-Ii), an important enzymeinvolved in bacterial resistance
