The isochorismate pyruvate lyase (IPL) from Pseudomonas aeruginosa, designated as PchB, catalyzes the transformation of isochorismate into pyruvate and salicylate, but it also catalyzes the rearrangement of chorismate into prephenate, suggesting that both reactions may proceed by a pericyclic mechanism....

Several 2-amino-4-carboxypyridine, 4- and 5-carboxypyridone-based compounds were prepared and tested against three members of the chorismate-utilising enzyme family, anthranilate synthase, isochorismate synthase and salicylate synthase. Most compounds exhibited low micromolar inhibition of these three enzymes. The most potent inhibitor was...
