Solution synthesis of antigenic and inhibiting peptides of the human renin prosegment‐1

The [Tyr47, Nle53] preprorenin (47–60) peptide methyl ester, a tetradecapeptide related to the human renin prosegment, has been synthesized using a three-segment coupling strategy. Selective deprotection of the segments before coupling allowed an easy removal of the final tetradecapeptide side chain-protecting groups by acidolysis and an easy purification. Antibodies raised against this peptide bound the plasmatic inactive renin.
