Abstract:
:Acyl carrier protein synthase (AcpS) catalyzes the transfer of the 4'-phosphopantetheinyl group from the coenzyme A to a serine residue in acyl carrier protein (ACP), thereby activating ACP, an important step in cell wall biosynthesis. The structure-based design of novel anthranilic acid inhibitors of AcpS, a potential antibacterial target, is presented. An initial high-throughput screening lead and numerous analogues were modeled into the available AcpS X-ray structure, opportunities for synthetic modification were identified, and an iterative process of synthetic modification, X-ray complex structure determination with AcpS, biological testing, and further modeling ultimately led to potent inhibitors of the enzyme. Four X-ray complex structures of representative anthranilic acid ligands bound to AcpS are described in detail.
