FRAGMENT-BASED DISCOVERY OF MEXILETINE DERIVATIVES AS ORALLY BIOAVAILABLE INHIBITORS OF UROKINASE-TYPE PLASMINOGEN ACTIVATOR


Overview

Fragment-based lead discovery has been applied to urokinase-type plasminogen activator (uPA). The (R)-enantiomer of the orally active drug mexiletine 5 (a fragment hit from X-ray crystallographic screening) was the chemical starting point. Structure-aided design led to elaborated inhibitors that retained the key interactions of (R)-5 while gaining extra potency by simultaneously occupying neighboring regions of the active site. Subsequent optimization led to 15, a potent, selective, and orally bioavailable inhibitor of uPA.
