We report the synthesis of (2E,5E)-4-oxoheptadienedioic acid and (2E)-4-oxoheptenedioic acid and evaluation of both diester and diacid analogues as inhibitors of bacterial dihydrodipicolinate synthase. Enzyme kinetic studies allowed the determination of second-order rate constants of inactivation; and substrate co-incubation studies have shown the inhibitors act at the active-site.
