The discovery of novel tartrate-based TNF-α converting enzyme (TACE) inhibitors

Synthesis and optimization of novel tartrate TACE inhibitors are described. A novel series of TNF-α convertase (TACE) inhibitors which are non-hydroxamate have been discovered. These compounds are bis-amides of l-tartaric acid (tartrate) and coordinate to the active site zinc in a tridentate manner. They are selective for TACE over other MMP’s. We report the first X-ray crystal structure for a tartrate-based TACE inhibitor.
