Second generation of PapR7-derived peptide combinations. (A) Sequences of first generation potent synthetic inhibitors 7-mer PapR-derived peptides (PapR7; ADLPFEF) involved D-amino acid or alanine replacements at three positions; proline (P) glutamic (E), and phenylalanine (F) of the heptapeptide PapR. (B) Sequences of second generation of PapR7-derived peptide combinations, involved double and triple alanine and D-amino acids replacement.
