The invention is based on the discovery of a new class of heterocyclic compounds having, for example, antibacterial properties. The D-Ala-D-Ala ligase enzyme is a critical pathway enzyme in the bacterial cell-wall synthesis. The compounds can bind to and inhibit the enzyme D-Ala-D-Ala ligase. The new compounds' activity combined with their ability to cross bacterial cell membranes makes them suitable for use as antibacterial drugs or other antibacterial applications.
