β-Hairpin peptidomimetics of the general formula Cyclo(-Xaa1-Xaa2-Xaa3-Xaa4-Xaa5-Xaa6-Xaa7-Xaa8-Xaa9-Xaa10-Xaa11-Xaa12-Xaa13-Xaa14-Xaa15-Xaa16-), and pharmaceutically acceptable salts thereof, with Xaa 1-Xaa 16 being amino acid residues of certain types which are defined in the description and the claims, have CXCR4 antagonizing properties and prolonged half-lives in vivo and can be used for preventing HIV infections in healthy individuals or for slowing and halting viral progression in infected patients; or where cancer is mediated or resulting from CXCR4 receptor activity; or where immunological diseases are mediated or resulting from CXCR4 receptor activity; or for treating immunosuppression; or during apheresis collections of peripheral blood stem cells and/or as agents to induce mobilization of stem cells to regulate tissue repair. These peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.
通式为Cyclo(-Xaa1-Xaa2-Xaa3-Xaa4-Xaa5-Xaa6-Xaa7-Xaa8-Xaa9-Xaa10-Xaa11-Xaa12-Xaa13-Xaa14-Xaa15-Xaa16-)的β-发夹肽类似物及其药学上可接受的盐,其中Xaa1-Xaa16是某些类型的氨基酸残基,其在说明书和权利要求中有定义,具有CXCR4拮抗作用和体内半衰期延长的特性,可用于预防健康个体的HIV感染,或减缓和阻止感染患者的病毒进展;或在CXCR4受体活性介导或导致癌症的情况下;或在CXCR4受体活性介导或导致免疫性疾病的情况下;或用于治疗免疫抑制;或在外周血干细胞分离和/或诱导干细胞移动以调节组织修复的代理中。这些肽类似物可以通过基于混合固相和溶液相合成策略的过程制造。
