Conversion of potent MMP inhibitors into selective TACE inhibitors

Novel sultam hydroxamates with potent MMP activity were transformed into potent TACE inhibitors, lacking MMP activity. To accomplish this we relied on structural differences between the MMP and TACE S1′ pockets and the known advantageous fit of a 2-methyl-4-quinolinylmethoxyphenyl group into this region. From this approach, compound 7d was identified as a potent TACE inhibitor (IC50 = 3.7 nM) that lacked MMP-1, -2, -9, and -13 activity.
