A convenient synthesis of 5-substituted 6-membered cyclic ureas is described. The key step involves intramolecular cyclization of 1,3-diaminopropane derivatives with urethane protecting groups on the nitrogen atoms.

Disclosed are compounds having polybasic functionalities. The compounds inhibit bacterial efflux pump inhibitors and are used in combination with an anti-bacterial agent to treat or prevent bacterial infections. These combinations can be effective against bacterial infections that have developed resistance to anti-bacterial agents through an efflux pump mechanism.
