DAGLUTRIL, SLV306

phase 2

Daglutril is a novel dual-action endopeptidase inhibitor which had been in phase II clinical development by Solvay for the treatment of hypertension, congestive heart failure (CHF) and pulmonary hypertension; however, no recent development has been reported for this research.

Daglutril inhibits NEP (neutral endopeptidase) and ECE (endothelin-converting enzyme) and thereby exerts vasodilating, blood pressure-lowering and other potentially beneficial effects on the cardiovascular system.

The acylation of the chiral amine (I) with the chiral cyclopentanecarboxylic aid (II) by means of N-methylmorphline (NMM), hydroxybenzotriazole (HOBT) and N-(dimethylaminopropyl)-N’-ethylcarbodiimide (EDT) in dichloromethane gives the amide (III), which is then treated with trifluoroacetic acid to elimnate the tert-butyl ester groups.
