Arylaminoethyl Amides as Novel Non-Covalent Cathepsin K Inhibitors
摘要:
A series of N-alpha-benzyloxycarbonyl- and N-alpha-acyl-L-leucine(2-phenylaminoethyl)amide derivatives were prepared and evaluated for their inhibitory activity against rabbit and human cysteine proteases cathepsins K, L, and S. These data indicate that N-alpha-acyl-alpha-amino acid-(arylaminoethyl)amides represent a new class of selective non-covalent inhibitors of cathepsin K. Compounds 4b, 4e, and 4g exhibit high potency toward rabbit and human cathepsin K (IC50 < 0.006 muM) and are characterized by an excellent selectivity profile vs human cathepsins L and S.
