Non-hydroxamate 5-phenylpyrimidine-2,4,6-trione derivatives as selective inhibitors of tumor necrosis factor-α converting enzyme

New inhibitors of tumor necrosis factor-α converting enzyme (TACE) were discovered with a pyrimidine-2,4,6-trione in place of the commonly used hydroxamic acid. These non-hydroxamate TACE inhibitors were developed by incorporating a 4-(2-methyl-4-quinolinylmethoxy)phenyl group, an optimized TACE selective P1′ group. Several leads were identified with IC50 values around 100 nM in a porcine TACE assay and selective over MMP-1, -2, -9, -13, and aggrecanase.
