  Photodegradable Supramolecular Hydrogels with Fluorescence Turn-On Reporter for Photomodulation of Cellular Microenvironments

  摘要：

  Photodegradable hydrogels that allow 3D encapsulation of cells are important biomaterials to modulate cellular microenvironments with temporal and spatial resolution. Herein we report a photodegradable hydrogel formed by the self-assembly of short peptides modified with a novel phototrigger. The phototrigger is a biaryl-substituted tetrazole moiety that, upon mild light irradiation, undergoes rapid intramolecular photoclick ligation to form a highly fluorescent pyrazoline moiety. Short peptides linked with a tetrazole-containing moiety, Tet(I) or Tet(II), are able to self-assemble into hydrogels, among which the Tet(I)-GFF and Tet(II)-GFRGD gels show good mechanical strength and biocompatibility for 3D encapsulation and prolonged culture of live cells. The phototriggered tetrazole-to-pyrazoline transformation generates a highly fluorescent reporter and induces the disassembly of the hydrogel matrix by disturbing the balance between hydrophilic interaction and it-if stacking of the self-assembled system. Photomodulation of cellular microenvironments was demonstrated not only for the cells grown on top of the gel but also for stem cells encapsulated inside the hydrogels.

  charge on TCFH. Poly(VC-co-TCFH) acted as a thermochromic sensor device generating immediate colorimetric changes from yellow to orange, red, wine, violet, and purple with increasing temperature of aqueous poly(VC-co-TCFH) solution. Such colorimetric changes are proportionally interrelated with the temperature increase from 33 to 47 °C due to a phase change in an aqueous solution of poly(VC-co-TCFH) copolymer

  CXC chemokine receptors 1 (CXCR1) and 2 (CXCR2) have been demonstrated to have critical roles in cancer metastasis. Because they share high homology sequences, it is still unclear how to design selective CXCR1 or CXCR2 antagonists. Based on a pharmacophore model we built, compound 2 bearing a 1,5-dihydro-4H-imidazol-4-one scaffold was identified as a selective CXCR2 antagonist with a low CXCR1 antagonism

  CXC 趋化因子受体 1 (CXCR1) 和 2 (CXCR2) 已被证明在癌症转移中具有关键作用。由于它们具有高度同源性序列，目前尚不清楚如何设计选择性CXCR1或CXCR2拮抗剂。基于我们建立的药效团模型，带有 1,5-二氢-4 H-咪唑-4-酮支架的化合物2被鉴定为具有低 CXCR1 拮抗偏好的选择性 CXCR2 拮抗剂。经过进一步的优化和构效关系研究，化合物C5克服了化合物2的缺点，具有更高的选择性。它表现出优异的口服生物利用度和体外抗癌转移活性。分子蛋白复合物的进一步动态模拟表明，CXCR2的氨基酸残基K320对C5的选择性贡献最大。该研究为设计新型CXCR2选择性拮抗剂提供了重要线索， C5可以作为研究CXCR1和CXCR2生物学功能差异的分子工具。

  Methylation reactions are of significant interest when generating pharmaceutically active molecules and building blocks for other applications. Synthetic methylating reagents are often toxic and unselective due to their high reactivity. S‐Adenosyl‐l‐methionine (SAM)‐dependent methyltransferases (MTs) present a chemoselective and environmentally friendly alternative. The anthranilate N‐MT from Ruta graveolens (RgANMT) is involved in acridone alkaloid biosynthesis, methylating anthranilate. Although it is known to methylate substrates only at the N‐position, the closest relatives with respect to amino acid sequence similarities of over 60 % are O‐MTs catalysing the methylation reaction of caffeate and derivatives containing only hydroxyl groups (CaOMTs). In this study, we investigated the substrate range of RgANMT and a CaOMT from Prunus persica (PpCaOMT) using compounds with both, an amino‐ and hydroxyl group (aminophenols) as possible methyl group acceptors. For both enzymes, the reaction was highly chemoselective. Furthermore, generating cofactor derivatives in situ enabled the transfer of other alkyl chains onto the aminophenols, leading to an enlarged pool of products. Selected MT reactions were performed at a preparative biocatalytic scale in in vitro and in vivo experiments resulting in yields of up to 62 %.

  摘要 甲基化反应在生成具有医药活性的分子和用于其他应用的构件时具有重要意义。合成甲基化试剂由于反应活性高，通常具有毒性和非选择性。依赖 S-腺苷-l-蛋氨酸（SAM）的甲基转移酶（MTs）提供了一种化学选择性和环境友好型的替代方法。Ruta graveolens 中的蚁酸 N-MT（RgANMT）参与吖啶酮生物碱的生物合成，将蚁酸甲基化。虽然已知它只能在 N 位甲基化底物，但氨基酸序列相似度超过 60% 的近亲是催化咖啡酸酯和仅含羟基的衍生物（CaOMTs）甲基化反应的 O-MTs 。在这项研究中，我们使用同时含有氨基和羟基（氨基苯酚）的化合物作为可能的甲基受体，研究了 RgANMT 和一种来自柿树的 CaOMT（PpCaOMT）的底物范围。这两种酶的反应都具有高度化学选择性。此外，原位生成辅助因子衍生物可以将其他烷基链转移到氨基苯酚上，从而扩大产物库。在体外和体内实验中，以制备生物催化的规模进行了选定的 MT 反应，结果产率高达 62%。
