  Discovery of (1S,2R,3R)-2,3-Dimethyl-2-phenyl-1-sulfamidocyclopropanecarboxylates: Novel and Highly Selective Aggrecanase Inhibitors

  摘要：

  Aggrecanases, particularly aggrecanase-1 (ADAMTS-4) and aggrecanase-2 (ADAMTS-5), are believed to be key enzymes involved in the articular cartilage breakdown that leads to osteoarthritis. Thus, aggrecanases are considered to be viable drug targets for the treatment of this debilitating disease. A cries of (1S,2R,3R)-2,3-dimethyl-2-phenyl-1-sulfamidocyclopropanecarboxylates was discovered to be potent, highly selective, aid orally bioavailable aggrecanase inhibitors. These compounds have unique P1' groups comprising novel piperidine- or piperazin e-based heterocycles that are connected to a cyclopropane amino acid scaffold via a sulfamido linkage. These P1' groups are quite effective in imparting selectivity over other MMPs, and this selectivity was further increased by incorporation of a methyl substituent in the 2-position of the cyclopropane ring. In contrast to classical hydroxamate-based inhibitors that tend to lack metabolic stability, our aggrecanase inhibitors bear a carboxylate zinc-binding group and have good oral bioavailability. Lead compound 13b, characterized by the novel P1' portion of 1,2,3,4-tetrahydropyrido[3',4':4,5]imidazo [1,2-a]-pyridine ring, is a potent and selective aggrecanse inhibitor with excellent pharmacokinetic profiles.
