摘要:
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.
摘要:
The invention is based on the discovery that certain small molecules can bind to the ATP binding site of D-Ala-D-Ala ligase, even in the absence of the enzyme's substrate, and can cause a conformational change in the enzyme structure similar to that which occurs upon binding of ATP and substrate to the enzyme. Without wishing to be bound by any theory, it is believed that such a conformational change is required for either activation or inhibition of the enzyme. The information obtained from this discovery has enabled identification of key interactions in the active site of the enzyme, as well as the design and opimization of inhibitors.
