Synthesis and Structure−Activity Relationship of α-Sulfonylhydroxamic Acids as Novel, Orally Active Matrix Metalloproteinase Inhibitors for the Treatment of Osteoarthritis
摘要:
The matrix metalloproteinases (MMPs) are a family of zinc-containing endopeptidases that play a key role in both physiological and pathological tissue degradation. These enzymes are strictly regulated by endogenous inhibitors such as tissue inhibitors of MMPs and alpha(2)-macroglobulins. Overexpression of these enzymes has been implicated in various pathological disorders such as arthritis, tumor metastasis, cardiovascular diseases, and multiple sclerosis. Developing effective small-molecule inhibitors to modulate MMP activity is one approach to treat these degenerative diseases. The present work focuses on the discovery and SAR of novel N-hydroxy-alpha-phenylsulfonylacetamide derivatives, which are potent, selective, and orally active MMP inhibitors.
Thiophene derivatives of the formula ##STR1## IN WHICH R.sub.x is --S--CHR.sub.5 --CONHOH or --S--CHR.sub.5 -5-tetrazolyl in which R.sub.5 is H or alkyl of 1-6 carbon atoms and R.sub.y is 0-2 of alkyl or alkoxy of 1-6 carbon atoms or halogen, and their pharmacologically acceptable salts with bases, possess antilipolytic activity.
An efficient, environmentally benign and unprecedented synthesis of various α-sulfenylated amides/esters has been developed under oxygen atmosphere. The reaction shows good functional group tolerance and excellent chemo/regioselectivity. All the desired products were obtained in moderate to excellent yields, even on the gram scale. Practically, the related α-thiol Weinreb amide can be readily transferred
