    • The invention concerns peptides derived from heliomicine by substitution of one or several amino acids, characterised in that said peptides correspond to formula (I): X1, X2, X3, X4, X5, X6, C7, X8, X9, X10, X11, X12, X13, X14, X15, X16, X17, C18, X19, X20, X21, C22 X23, X24, X25, X26, X27, X28, X29, X30, X31, X32, X33, X34, X35, X36, X37, X38, X39, C40, X41, C42, X43, X44 wherein: X1, X17, X21 X43 are amino acids; X16, X44 are small polar amino acids; X19 is a large polar amino acid; X36 is a small or lightly hydrophobic amino acid; X38 is a lightly hydrophobic or small amino acid; said substitutions being such that: at least one of X1, X17, X21, X43 is a basic or polar, advantageously large polar amino acid, and/or at least one of the amino acids X16, X44 is a basic amino acid or a large polar amino acid, and/or X19 is a basic amino acid, and/or at least one of the amino acids X36, X38 is a strongly hydrophobic amino acid. The invention also concerns antifungal and/or antibacterial compositions comprising at least one of said peptides.
    • 本发明涉及通过取代一个或几个氨基酸衍生自heliomicine的肽,其特征在于所述肽对应于式(I):X1,X2,X3,X4,X5,X6,C7,X8,X9,X10,X11, X12,X13,X14,X15,X16,X17,C18,X19,X20,X21,C22 X23,X24,X25,X26,X26,X27,X28,X29,X30,X31,X32,X33, ,X38,X39,C40,X41,C42,X43,X44,其中:X1,X17,X21,X43是氨基酸; X16,X44是小极性氨基酸; X19是一种大型极性氨基酸; X36是一种小的或轻度疏水的氨基酸; X38是轻度疏水或小氨基酸; 所述取代是这样的:X1,X17,X21,X43中的至少一个是碱性或极性的,有利的是大的极性氨基酸,和/或至少一个氨基酸X16,X44是碱性氨基酸或大的 和/或X19是碱性氨基酸,和/或至少一个氨基酸X36,X38是强疏水性氨基酸。 本发明还涉及包含至少一种所述肽的抗真菌和/或抗菌组合物。
