Through directed screening of compounds prepared as metalloprotease inhibitors a compound, CGS 30084 , that had potent endothelin converting enzyme-1 (ECE-1) in vitro inhibitory activity (IC 50 =77 nM) was identified. Herein we report the synthesis and optimization of ECE-1 inhibitory activity of additional analogues from this lead. Compound 3c , the thioacetate methyl ester derivative of compound 4c , was found to be a long acting inhibitor of ECE-1 activity in rats after oral administration. |
