factors that help establish and maintain infection. Disruption of such secretion systems is a potentially effective therapeutic strategy. We developed a high-throughput screen and identified a tris-aryl substituted 2-imino-5-arylidenethiazolidin-4-one, compound 1, as an inhibitor of the type III secretion system. Expansion of this chemotype enabled us to define the essential pharmacophore for type III

and synthesis of 12 novel DDAH-1inhibitors and report their derived kinetic parameters, IC50 and Ki. Arginine analogue 10a, characterized by an acylsulfonamide isosteric replacement of the carboxylate, showed a 13-fold greater inhibitory potential relative to the known DDAH-1inhibitor, L-257. Compound 10a was utilized to study the putative binding interactions of humanDDAH-1 inhibition using molecular
