    • Methods of covalently-stabilizing alpha-helical, chimeric peptides constrained within a homotrimeric or heterotrimeric coiled-coil structure are disclosed. The coiled-coil structures made by the methods disclosed within this specification mimic all or a portion of the internal, trimeric coiled-coil motif contained within the fusogenic conformation of an enveloped virus membrane-fusion protein, particularly the internal coiled-coil domain of the HIV gp41 ectodomain. The HIV-derived, chimeric peptides disclosed comprise a non-HIV, soluble, trimeric form of a coiled-coil fused in helical phase to all or a portion of the N-helix of HIV gp41 and are covalently-stabilized in a homotrimeric or heterotrimeric coiled-coil structure through the formation of disulfide or chemoselective bonds between said peptides. The covalently-stabilized, HIV-derived, homotrimeric or heterotrimeric coiled-coil structures made by the methods disclosed herein represent a close mimetic of a HIV gp41 fusion intermediate and are potent inhibitors of HIV infectivity. These HIV-derived chimeric peptides may provide for therapeutic treatment against HIV infection by inhibiting the virus-host cell membrane fusion process.
    • 公开了限制在同三聚体或异三聚体卷曲螺旋结构内的共价稳定的α-螺旋嵌合肽的方法。 通过本说明书中公开的方法制备的盘绕线圈结构模拟包含在包膜病毒膜 - 融合蛋白的融合构象内的内部三聚体卷曲螺旋基序的全部或一部分,特别是内部卷曲螺旋结构域 HIV gp41胞外域。 所公开的HIV衍生的嵌合肽包含螺旋状螺旋状的非HIV,可溶性三聚体形式,其与HIV gp41的全部或部分N-螺旋融合,并且以同三聚或异三聚体共价稳定 通过在所述肽之间形成二硫键或化学选择性键来进行卷曲螺旋结构。 由本文公开的方法制备的共价稳定的HIV衍生的同源三聚体或异三聚体卷曲螺旋结构代表HIV gp41融合中间体的密切模拟物,并且是HIV感染性的有效抑制剂。 这些HIV衍生的嵌合肽可以通过抑制病毒宿主细胞膜融合过程来提供针对HIV感染的治疗性治疗。
