bicyclam AMD3100 (1) are a class of potent and selective anti-HIV-1 agents that inhibit virus replication by binding to the chemokine receptor CXCR4, the coreceptor for entry of X4 viruses. By sequential replacement and/or deletion of the amino groups within the azamacrocyclic ring systems, we have determined the minimum structural features required for potent antiviral activity in this class of compounds
Bis-tetraazamacrocycles,例如bicyclam AMD3100(1),是一类有效的选择性HIV-1药物,可通过与趋化因子受体CXCR4(X4病毒进入的核心受体)结合而抑制病毒复制。通过连续置换和/或删除氮杂大环系统中的氨基,我们确定了此类化合物中强效抗病毒活性所需的最小结构特征。活性并不需要全部八个氨基,每个环上的关键氨基是不相同的,并且可以在不影响效能的情况下降低生理pH值下的总电荷。这种方法导致鉴定了几种单环氮杂大环类似物,例如AMD3465(3d),36,和40,分别对9.0、1.0和4.0 nM的HIV-1的细胞毒性作用表现出EC 50,抗病毒效力可与1相当(对HIV-1的4.0 nM的EC 50)。但是,更重要的是,抗病毒活性所需的1的关键结构要素可能有助于设计适合于通过口服HIV治疗的非大环CXCR4拮抗剂。
