Cyclic Human Immunodeficiency Virus (HIV) Principal Neutralizing Determinant (PND) peptides, or peptides immunologically equivalent therewith, wherein the ring system of the cyclic peptide is formed by ring closure through a stable amide bond, are useful as analytical tools, as reagents in ELISA assays, or as reagents for making covalent conjugate immunogens. Conjugates containing these stable, cyclic peptides are useful for raising mammalian anti-peptide, anti-HIV, or HIV-neutralizing immune responses, and a composition containing such a conjugate may be used as a vaccine to prevent HIV-Disease, including Acquired Immune Deficiency Syndrome, (AIDS), or AIDS related complex, (ARC), or as an immunogen for treating humans afflicted with HIV-Diseases, such as AIDS or ARC.
环状人类免疫缺陷病毒(HIV)主要中和决定簇(
PND)肽或与之免疫等效的肽,其中环肽的环系统是通过稳定的酰胺键闭环形成的,可用作分析工具、ELI
SA 检测试剂或制造共价结合免疫原的试剂。含有这些稳定环肽的共轭物可用于提高哺乳动物的抗肽、抗 HIV 或 HIV 中和免疫反应,含有这种共轭物的组合物可用作预防 HIV 疾病(包括获得性免疫缺陷综合征(AIDS)或 AIDS 相关综合征(ARC))的疫苗,或用作治疗人类 HIV 疾病(如 AIDS 或 ARC)的免疫原。
