    • Tetrapeptides consisting of (I or V)-X1-K-X2, where X1 can be selected from E, Q or K, and X2 can be selected from M, F, I, W, or V, exhibit diverse bioactivities. They are multi-functional effector molecules to stimulate keratinocytes migration; neutralize the proinflammatory effect of bacterial cell wall components such as lipoteichoic acids of the Gram-positive S. aureus; and induce angiogenesis in cultured human umbilical vein endothelial cells. The downregulation of pro-inflammatory condition was also demonstrated using SOR-300-FT psoriasis skin model for representative peptide. The bioactivity was also supported by gene profiling study upon treatment of normal skin tissues using EPIDERM TM skin substitutes. The inventive peptides with diverse bioactivities are useful for treating various skin conditions including, but not limited to, acute or chronic wounds, striae distensae, aging skin, hair control, inflammatory skins such as psoriasis, atopic dermatitis and rosacea and for unwanted hair removal or for conditions such as removal of skin tags.
    • 由(I或V)-X1-K-X2组成的四肽,其中X1可以选自E,Q或K,X2可以选自M,F,I,W或V,表现出不同的生物活性。 它们是多功能效应分子刺激角质细胞迁移; 中和细菌细胞壁组分如革兰氏阳性金黄色葡萄球菌的脂磷壁酸的促炎作用; 并在培养的人脐静脉内皮细胞中诱导血管生成。 使用代表性肽的SOR-300-FT牛皮癣皮肤模型也证实了促炎症状的下调。 使用EPIDERMTM皮肤替代品治疗正常皮肤组织时,生物活性也得到基因谱学研究的支持。 具有不同生物活性的本发明的肽可用于治疗各种皮肤病症,包括但不限于急性或慢性伤口,纹状裂纹,老化皮肤,毛发控制,炎性皮肤如牛皮癣,特应性皮炎和酒渣鼻,以及不需要的毛发去除 用于除去皮肤标签等条件。

    • Disclosed are peptides having biological and therapeutic activity. Particularly disclosed are lipidated di- or tri- peptides analogs of KPV or KdPT that exhibit antimicrobial activity. In particular, the peptides of this invention provide enhanced anti-microbial activity over the base tri -peptides, lysine -proline- valine and lysine-d-proline-tyrosine. The disclosed peptides have the general formula of C12-18 lipid— KXZ-NH 2 i wherein K is lysine; X is proline, d-proline, histidine or arginine; Z is optional and if present Z is valine, threonine, alanine or leucine; and the terminal COOH is NH 2 amidated. The C12-18 lipid is preferably the lipid moiety of lauric acid (C12), myristic acid (C14), pentadecanoic acid (C15), palmitic acid (C16), or stearic acid (C18). The invention is further related to methods of using of these peptides to treat various insults, inflammations or bacterial infections affecting the skin and other related mucosal body surfaces such as the oral cavity.
    • 公开了具有生物和治疗活性的肽。 特别公开了表现出抗微生物活性的KPV或KdPT的脂化二或三肽类似物。 特别地,本发明的肽相对于碱基三肽,赖氨酸 - 脯氨酸 - 缬氨酸和赖氨酸-d-脯氨酸 - 酪氨酸提供增强的抗微生物活性。 所公开的肽具有通式C12-18脂质KXZ-NH2i,其中K是赖氨酸; X是脯氨酸,脯氨酸,组氨酸或精氨酸; Z是任选的,如果存在Z是缬氨酸,苏氨酸,丙氨酸或亮氨酸; 并且末端COOH是NH 2酰胺化的。 C12-18脂质优选为月桂酸(C12),肉豆蔻酸(C14),十五烷酸(C15),棕榈酸(C16)或硬脂酸(C18)的脂质部分。 本发明还涉及使用这些肽来治疗影响皮肤和其它相关粘膜体表如口腔的各种侮辱,炎症或细菌感染的方法。
