Synthesis and biological evaluation of biphenylsulfonamide carboxylate aggrecanase-1 inhibitors

Aggrecanases are recently discovered enzymes that cleave aggrecan, a key component of cartilage. Aggrecanase inhibitors may provide a unique means to halt the progression of cartilage destruction in osteoarthritis. The synthesis and evaluation of biphenylsulfonamidocarboxylic acid inhibitors of aggrecanase-1 are reported. Compound 24 demonstrated 89% inhibition of proteoglycan degradation at 10 μg/mL and has an oral bioavailability in rat of 35%.
