Abstract :
Anti-succinate hydroxamates with cyclic P1 motifs were synthesized as aggrecanase inhibitors. The N-methanesulfonyl piperidine 23 and the N-trifluoroacetyl azetidine 26 were the most potent aggrecanase inhibitors both having an IC50=3 nM while maintaining >100-fold selectivity over MMP-1, -2, and -9. The cyclic moieties were also capable of altering in vivo metabolism, hence delivering low clearance compounds in both rat and dog studies as shown for compound 14.
