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.
