Peptide Science 2023, 2024年08月, [査読有り] - In situ detection of enzymatic activities by the bioorthogonal reaction-coupled assay using a dialkoxysilylated fluorogenic probe
Daisuke Sato; Yuya Matsuo; Yuki Nishime; Shohei Uchinomiya; Akio Ojida, 筆頭著者, Abstract
Fluorescent probes are indispensable tools for detection of enzymatic activities. However, detection of enzymes with high substrate specificity with substrate-based fluorescent probes is still challenging, due to their relatively large molecular size. We report herein enzyme assays coupled with a bioorthogonal fluoride ion-induced desilylation of fluorogenic probe. This sensing system is useful for in situ detection of enzyme reactions with high substrate specificity., Oxford University Press (OUP)

New Journal of Chemistry, 2023年, [査読有り] - Design, Synthesis, and Photo-Responsive Properties of a Collagen Model Peptide Bearing an Azobenzene
Daisuke Sato; Hitomi Goto; Yui Ishizaki; Tetsuya Narimatsu; Tamaki Kato, 筆頭著者, Collagen is a vital component of the extracellular matrix in animals. Collagen forms a characteristic triple helical structure and plays a key role in supporting connective tissues and cell adhesion. The ability to control the collagen triple helix structure is useful for medical and conformational studies because the physicochemical properties of the collagen rely on its conformation. Although some photo-controllable collagen model peptides (CMPs) have been reported, satisfactory photo-control has not yet been achieved. To achieve this objective, detailed investigation of the isomerization behavior of the azobenzene moiety in CMPs is required. Herein, two CMPs were attached via an azobenzene linker to control collagen triple helix formation by light irradiation. Azo-(PPG)10 with two (Pro-Pro-Gly)10 CMPs linked via a photo-responsive azobenzene moiety was designed and synthesized. Conformational changes were evaluated by circular dichroism and the cis-to-trans isomerization rate calculated from the absorption of the azobenzene moiety indicated that the collagen triple helix structure was partially disrupted by isomerization of the internal azobenzene., MDPI AG
Organics, 2022年10月11日, [査読有り] - Design, Synthesis, and Utility of Defined Molecular Scaffolds
Daisuke Sato; Zhiyuan Wu; Hikaru Fujita; Jonathan Lindsey, 筆頭著者, A growing theme in chemistry is the joining of multiple organic molecular building blocks to create functional molecules. Diverse derivatizable structures—here termed “scaffolds” comprised of “hubs”—provide the foundation for systematic covalent organization of a rich variety of building blocks. This review encompasses 30 tri- or tetra-armed molecular hubs (e.g., triazine, lysine, arenes, dyes) that are used directly or in combination to give linear, cyclic, or branched scaffolds. Each scaffold is categorized by graph theory into one of 31 trees to express the molecular connectivity and overall architecture. Rational chemistry with exacting numbers of derivatizable sites is emphasized. The incorporation of water-solubilization motifs, robust or self-immolative linkers, enzymatically cleavable groups and functional appendages affords immense (and often late-stage) diversification of the scaffolds. Altogether, 107 target molecules are reviewed along with 19 syntheses to illustrate the distinctive chemistries for creating and derivatizing scaffolds. The review covers the history of the field up through 2020, briefly touching on statistically derivatized carriers employed in immunology as counterpoints to the rationally assembled and derivatized scaffolds here, although most citations are from the past two decades. The scaffolds are used widely in fields ranging from pure chemistry to artificial photosynthesis and biomedical sciences., MDPI AG
