Abstract

The [1-asparagine]angiotensin analogue was synthesized by fragment condensation employing the azide method. Proline in the position 7 in this analogue and phenylalanine in the position 8 were substituted with 2-[1-(2-oxo-3-aminopyrrolidinyl)]-3-phenylpropanoic acid. The analogue does not exhibit any agonistic nor antagonistic activity in myotropic, histamin releasing and pressoric tests.
