    • The invention encompasses hexapeptides consisting of alternating hydrophobic residues (B) at positions 2, 4, and 6, hydrophilic, hydrophilic, charged residues (X) at positions 1 and 3, and a naphthylalanine (NaI), an aliphatic or aromatic residue (O) at position five, represented generally by the formula XBXBOB, which exhibit antimicrobial activity against infections caused by a variety of pathogens. These pathogens may include gram positive or negative bacteria, acid-fast bacteria such a mycobacteria, parasites, dermatophytes, or fungal pathogens. Typical fungal pathogens include Candida albicans and typical dermatophytes include Trichophyton rubrum and Trichophyton mentagrophytes. The hexapeptides of the present invention exhibit antifungal activity, antibacterial activity, desirable stability, and lack toxicity to the mammal receiving treatment.
    • 本发明包括在位置2和4处交替疏水残基(B),位置1和3处的亲水性,亲水性,带电荷的残基(X)和萘丙氨酸(NaI),脂族或芳族残基(O ),通常由式XBXBOB表示,其表现出针对由各种病原体引起的感染的抗微生物活性。 这些病原体可以包括革兰氏阳性或阴性细菌,耐酸细菌如分枝杆菌,寄生虫,皮肤癣菌或真菌病原体。 典型的真菌病原体包括白色念珠菌和典型的皮肤癣菌包括红色毛癣菌和引发毛癣菌。 本发明的六肽对接受治疗的哺乳动物具有抗真菌活性,抗菌活性,理想的稳定性和缺乏毒性。
