Comment: AZ1 is a sulfonyl piperazine compound with antibacterial activity, discovered using a high-throughput phenotypic screen [3]. It is a novel inhibitor of bacterial cell wall synthesis that acts by targeting UDP-2,3-diacylglucosamine hydrolase (LpxH), an enzyme in the lipopolysaccharide synthesis pathway [1]. LpxH is an essential enzyme, conserved in the majority of Gram-negative bacteria but absent in human, and an attractive target for antibacterial development.
