Disclosed are linear discrete PEG constructs, which can be created and produced in a precise and reproducible way. Key to being able to do these things, where x in the discrete PEGX can vary from about 2 to about 64, is that the processes used to make each linear portion is controlled to give essentially one oligomer/one compound. Having a variable length linear discrete PEG construct that is (a) primarily an linear discrete PEG construct with diagnostic or therapeutic groups attached along a chain of attachment cores, which is attached to a preferential locator; (b) is an m-discrete PEG as the terminal construct on the linear portion, and "hidden"; (c) or linear discrete PEG with a terminus group that can be either negatively or positively charged, or neutral; and any of the discrete PEG portions can be designed to be cleaved after entering the cell.
披露了线性离散PEG构造,可以以精确和可重复的方式创建和生产。能够做到这些的关键是,离散PEGX中的x可以在大约2到大约64之间变化,用于制造每个线性部分的过程被控制,以基本上提供一个寡聚体/一个化合物。具有可变长度的线性离散PEG构造,(a) 主要是具有连接诊断或治疗基团的沿着附着核心链附着的线性离散PEG构造,附着在优选定位器上; (b) 是线性部分上的末端构造的m-离散PEG,并且“隐藏”; (c) 或线性离散PEG,带有可以是负电荷、正电荷或中性的终端基团; 任何离散PEG部分都可以设计为进入细胞后被切割。
