We synthesized 18 alloferon analogues : 12 peptides with sequences shortened from N - or C - terminus and 6 N - terminally modified analogues H - X ( 1 ) - Gly - Val - Ser - Gly - His - Gly - Gln - His - Gly - Val - His - Gly - OH , where X ( 1 ) = Phe ( 13 ) , Tyr ( 14 ) , Trp ( 15 ) , Phg ( 16 ) , Phe ( p - Cl ) ( 17 ) , and Phe ( p - OMe ) ( 18 ) .
