Description

LY-3000328 is a Cathepsin S inhibitor with excellent in vitro potency and selectivity against other cysteine proteases. LY-3000328 is currently in clinical trials. Cathepsin S (Cat S) plays an important role in many pathological conditions, including abdominal aortic aneurysm (AAA). Inhibition of Cathepsin S may provide a new treatment for AAA.
