Abstact

A series of tetrahydropyrido-pyrazole cathepsin S (CatS) inhibitors with thioether acetamide functional groups were prepared with the goal of improving upon the cellular activity of amidoethylthioethers. This Letter describes altered amide connectivity, in conjunction with changes to other binding elements, resulting in improved potency, as well as increased knowledge of the relationship between this chemotype and human CatS activity.
