  日期：1965.2.1

  The 15.1 Mc/s 13C n.m.r. spectra of 21 substituted alkyl phenyl ketones, ArCOR, have been determined and the 13C chemical shifts measured. This group of compounds included examples of each of the ethyl, isopropyl, and t-butyl phenyl ketone series. Variations of the chemical shifts with structure are analyzed and compared with the results for substituted acetophenones. The study of steric inhibition

  Disclosed are an eight-arm polyethylene glycol (PEG) derivative (formula I), production method therefor and modified bio-related substance thereby. Wherein, one tetravalent group U together with four trivalent groups Ec form a highly symmetrical octavalent group CORE0; Lc connects the octavalent group to eight PEG chains having polydispersity or monodispersity and having n1 to n8 as the degree of polymerization thereof; the terminal of one PEG chain is connected to at least one functional group F (k≥1); said PEG chain and F therebetween can be directly connected (g=0) or be indirectly connected via a linking group L0 to a terminal end-branching group G (g=1); the latter provides more reactive sites for binding more drug molecules and increases the drug loading. The eight-arm polyethylene glycol derivative has a centrosymmetric or approximately centrosymmetric structure, and leads to more precise control of the molecular weight in large-scale production and much narrower distribution of molecular weight for products. The modified bio-related substance thereby has a more uniform and controllable performance.

  本发明公开了一种八臂聚乙二醇（PEG）衍生物（式 I）、其生产方法及其改性生物相关物质。其中，一个四价基团 U 与四个三价基团 Ec 形成一个高度对称的八价基团 CORE0；Lc 将八价基团连接到八条具有多分散性或单分散性且聚合度为 n1 至 n8 的 PEG 链上；一条 PEG 链的末端与至少一个官能团 F 连接（k≥1）；所述 PEG 链和 F 之间可以直接连接（g=0），也可以通过连接基团 L0 与末端支化基团 G 间接连接（g=1）；后者提供了更多的反应位点，可以结合更多的药物分子，增加药物负载量。八臂聚乙二醇衍生物具有中心对称或近似中心对称结构，因此在大规模生产中可以更精确地控制分子量，产品的分子量分布也更窄。因此，改性生物相关物质的性能更均匀、更可控。

  Disclosed are a multifunctionalized polyethylene glycol derivative and a preparation method therefor. The derivative has an H-shaped structure as represented by formula (1) and comprises one linear core LPEG and four PEG branch chains, where n 1 , n 2 , n 3 , and n 4 respectively are the degrees of polymerization of the branch chains, U 1 and U 2 are trivalent branching groups connecting the core LPEG to two of the PEG branch chains, F 1 and F 2 contain a functional group or a protected form R 01 thereof and may or may not contain a branched group G, correspondingly, the number of R 01 is one or more, F 1 and F 2 are either identical or different, any one linking group in the molecule or any linking group formed with an adjacent heteroatom group can either remain stable or be degraded, and any one PEG segment in the molecule is discretely polydispersed or monodispersed. The multifunctional polyethylene glycol is flexible and diverse in terms of branch structures and the lengths of branching arms, has various parameters and performance indicators that are adjustable and easy to control, and has a broad applicability.
