  溶液和磷脂双层中折叠体构象的双芘探针†

  摘要：

  探索膜相中合成分子的详细结构特征需要灵敏的构象探针。在这里，我们描述了报告膜活性动态折叠体中构象变化的双（芘）探针的设计、合成和表征。探针设计用于区分溶液和双层膜中的 3个 10-螺旋 α-氨基异丁酸 (Aib) 肽折叠体的左旋 ( M ) 和右旋 ( P ) 螺旋式构象异构体。合成了几种不同的双（芘）探针并将其连接到在N端具有不同手性残基的 Aib 四聚体的 C 端，这些残基在 310-螺旋。易于合成且方便掺入的N-乙酰基-1,2-双（芘-1'-基）乙二胺探针被证明具有最佳性能。在溶液中，折叠体螺旋感的变化导致该构象报告者的准分子/单体荧光发射（ E / M）比率发生显着变化，X射线晶体学显示相反的螺旋感产生非常不同的芘间距离记者。在双层中，这种方便且灵敏的荧光报告器首次允许研究天然磷脂的手性如何影响折叠体构象。

  A Non-Covalent Strategy for the Assembly of Supramolecular Photocurrent-Generating Systems

  摘要：

  Three photocurrent-generating thin films were assembled on gold surfaces. SAM I was constructed from molecules consisting of an alkyl disulfide group linked covalently to a 12-residue helical peptide and terminated with an alanine residue containing a pyrene chromophore. SAM I served as a benchmark for multilayered films II and III in photocurrent generation experiments. Films II and III were assembled from several components that were linked noncovalently by metal-ligand complexation. Cyclic voltammetry and contact angle measurements suggest that the films consist of ordered layers with relatively few defects. Photoexcitation of SAM I by the output of a 350 nm lamp ( approximately 0.2 mW power incident on the sample) results in current generation in the range 5-10 nA/cm2. Photoexcitation of II and III yields higher current in the range 10-30 nA/cm2, representing a quantum efficiency of approximately 1%. The observation of comparable or higher current from noncovalently assembled multicomponent films indicates that this method of assembly may obviate the problems associated with the covalent assembly of devices from large molecules.

  Disclosed are an 8-arm polyethylene glycol (PEG) derivative (formula 1), manufacturing method and modified bio-related substance thereby, wherein a tetravalent group U and four trivalent groups Ec form a highly symmetric octavalent central structure CORE0 together, Lc connects the octavalent center to eight PEG arms having polydiversity or monodiversity and having n1-n8 as the degrees of polymerization thereof. The terminal of one PEG chain is connected to at least one functional group F (k ≥ 1), and said PEG chain and F can be directly connected (g = 0) or connected with a divalent linking group L0 connected with a terminal branched group G (g = 1) therebetween. The latter provides more reacting sites to combine more pharmaceutical molecules, thereby increasing the drug loading capacity. The near-center symmetric structure of the derivative allows more precise control over the molecular weight during large-scale production, thereby facilitating acquisition of a product having a narrower molecular weight distribution. A bio-related substance modified thereby has a more uniform and controllable performance.

  本发明公开了一种 8 臂聚乙二醇（PEG）衍生物（式 1）、其制造方法和改性生物相关物质，其中一个四价基团 U 和四个三价基团 Ec 共同形成一个高度对称的八价中心结构 CORE0，Lc 将八价中心连接到八个 PEG 臂上，这些 PEG 臂具有多元性或单元性，其聚合度为 n1-n8。一条 PEG 链的末端与至少一个官能团 F（k ≥ 1）相连，所述 PEG 链和 F 可以直接相连（g = 0），也可以通过二价连接基 L0 与中间的末端支化基 G（g = 1）相连。后者提供了更多的反应位点，可以结合更多的药物分子，从而提高药物负载能力。衍生物的近中心对称结构可以在大规模生产过程中更精确地控制分子量，从而有利于获得分子量分布更窄的产品。由此改性的生物相关物质具有更均匀、更可控的性能。

  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.
