  用于在水中自组装和形成生物功能超分子水凝胶的多功能小分子基序

  摘要：

  这篇专题文章介绍了新的结构基序（称为“samogen”），它们作为水凝胶剂的构建块，用于分子在水中的自组装，从而产生一系列超分子水凝胶。使用由两个苯丙氨酸残基和一个萘基组成的化合物（也缩写为 NapFF ( 1) 在本文中) 作为 samogens 的一个例子，我们展示了 samogens 将生物活性分子转化为分子水凝胶剂的能力，这些分子水凝胶剂在水中自组装以产生纳米纤维。通过简要总结这些衍生自 samogens 的分子水凝胶的特性和应用（例如，伤口愈合、药物输送、控制细胞命运、分型细菌和催化），我们打算说明小分子水凝胶的基本要求和前景用于化学、材料科学和生物医学领域的应用。

  hydrogelators for molecular self-assembly in water to result in a series of supramolecular hydrogels. Using a compound that consists of two phenylalanine residues and a naphthyl group (also abbreviated as NapFF (1) in this text) as an example of the samogens, we demonstrated the ability of the samogens to convert bioactive molecules into molecular hydrogelators that self-assemble in water to result in nanofibers

  Disclosed are peptides that contain up to about 35 amino acids, including a plurality of aromatic amino acid residues and either (i) an amino acid residue that is phosphorylated or sulfated, or (ii) an amino acid comprising an ester-moiety linked via peptide bond, or both (i) and (ii), wherein the peptide is capable of self-assembly to form nanofibrils in the presence of an enzyme that hydrolyzes the phosphate group, the sulfate group, or the ester-moiety. These peptides are enzymatically responsive hydrogelators, and they can be used to form pericellular hydrogels/nanofibrils upon exposure to target cells that secrete or express a surface bound ectoenzyme having hydrolase activity suitable to induce peptide gelation. These materials, and compositions containing the same, can be used for in vitro and in vivo cellular imaging, treating cancerous conditions, collecting a secretome from a cell upon which the pericellular hydrogels/nanofibrils form, and screening the collected secretome.

  Peptides made of d-amino acids, as the enantiomer of corresponding l-peptides, are able to resist proteolysis. It is, however, unclear or much less explored whether or how d-amino acids affect the cellular response of supramolecular nanofibers formed by enzyme-triggered self-assembly of d-peptides. In this work, we choose a cell compatible molecule, Nap-l-Phe-l-Phe-l-pTyr (LLL-1P), and systematically replace the l-amino acids in this tripeptidic precursor or its hydrogelator by the corresponding d-amino acid(s). The replacement of even one d-amino acid in this tripeptidic precursor increases its proteolytic resistance. The results of static light scattering and TEM images show the formation of nanostructures upon the addition of alkaline phosphatase, even at concentrations below the minimum gelation concentration (mgc). All these isomers are able to form ordered nanostructures and exhibit different morphologies. According to the cell viability assay on these stereochemical isomers, cells exhibit drastically different responses to the enantiomeric precursors, but almost same responses to the enantiomeric hydrogelators. Furthermore, the different cellular responses of LLL-1P and DDD-1P largely originate from the ecto-phosphatases catalyzed self-assembly of DDD-1 on the surface of cells. Therefore, this report not only illustrates a new way for tailoring the properties of supramolecular assemblies, but also provides new insights to answering the fundamental question of how mammalian cells respond to enzymatic formation of nanoscale supramolecular assemblies (e.g., nanofibers) of d-peptides.
