Four new HN-derivatives were synthesized: Y-PAGASRLLLTGEIDLP (Y-des-Leu-RG-PAGA, 1), Y-PAGASRLLLLTGEIDLP (Y-RG-PAGA, 2), Y-SALLRSIPAPAGASRLLLTGEIDLP (Y-des-Leu-Colivelin, 3), Y-SALLRSIPAPAGASRLLLLTGEIDLP (Y-Colivelin, 4), their neuroprotective action was evaluated in the T-maze test and the most active ones were monoradioiodinated with 125I and the labelled peptides used for binding and biodistribution studies.
