Ra. Galemmo et al., THE DE-NOVO DESIGN AND SYNTHESIS OF CYCLIC UREA INHIBITORS OF FACTOR XA - INITIAL SAR STUDIES, Bioorganic & medicinal chemistry letters, 8(19), 1998, pp. 2705-2710
In this report we discuss the design, synthesis, rind validation of a
novel series of cyclic urea inhibitors of the blood coagulation protei
n Factor Xa. This work culminates in compound 11, a mono-amidine inhib
itor of fXa employing a new S4 ligand that reduces the cationic charac
ter of these analogs. Compound 11 represents a lead for a series of mo
re potent and selective inhibitors. (C) 1998 The DuPont Merck Pharmace
