The invention relates to an intermedin analogue prepared by bonding a ring core sequence with biotin or cell-penetrating peptides and a preparation method and application of the intermedin analogue. The intermedin analogue is prepared by bonding a functional unit with the biotin or a load unit; the functional unit is a seven-peptide structure formed by connecting the ring core sequence c (Asp-Dab-D-Phe-Arg-Trp-Lys) with a connection unit Arg, the structure is Arg-c (Asp-Dab-D-Phe-Arg-Trp-Lys); the load unit is the 48th-57th peptide segments Gly-Arg-Lys-Lys-Arg-Arg-Gln-Arg-Arg-Arg or the 55th-57th peptide segments Arg-Arg-Arg in the 47th-60th segments of HIV (human immunodeficiency virus)-1TAT protein. The intermedin analogue disclosed by the invention can penetrate through mucosa or skin to be absorbed, and can be applied to treatment of diseases such as male and female sexual dysfunction, obesity, pigmentation deficiency and the like.

Novel peptides with antimicrobial activity are disclosed. The novel peptides are octomeric peptides modified from alpha-MSH. The modified alpha-MSH antimicrobial peptides disclosed herein may have enhanced activity against microbes over alpha-MSH due to modifications in peptide sequence and chirality of amino acids. Due an identified mechanism of action for antimicrobial activity in which cAMP accumulates in the microbial cell, it may be that microbes will not generate resistance to these modified alpha-MSH antimicrobial peptides.
