Large‐Scale Chemoenzymatic Synthesis of a Glycophorin A Tetrasaccharide Motif and Its Analogues

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A large‐scale chemoenzymatic method was developed to synthesize natural and modified analogues of the Glycophorin A tetrasaccharide with either C9 or C5 terminal α‐2,3‐sialic acid variants. Selective α‐2,6‐sialylation of galactosamine was achieved by maintaining acetylation of the galactose during the course of enzymatic reactions. The products can aid

Synthesis of 1‐Naphthylamines Utilizing [4 + 2] Cycloaddition Between 3‐Amino‐2‐pyrones and Benzynes

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Synthesis of 1‐naphthylamines is developed using [4 + 2] cycloaddition between 3‐amino‐2‐pyrone, which is prepared by the conjugate addition reaction of diethyl 2‐aminomalonate to alkynyl ketones, and benzyne generated from o‐silylaryl triflates. This synthetic strategy was successfully applied to the syntheses of iodonaphthalene, naphthylimide, and ...

Chirality Makes or Breaks Chemically Driven Self‐Assembly

open access: yesAngewandte Chemie, EarlyView.
Chirality‐controlled reaction cycles: Reaction cycles are constructed to respond to the chirality (handedness) of an acylating agent. Left‐ and right‐handed aminoacyl phosphate esters modulate the structure, lifetime, and transformation of transient (thio)ester intermediates, enabling control over distinct chemical pathways using molecules that are ...

N‐Amino Peptide–Graphene Quantum Dot Loaded Small Extracellular Vesicles for Targeted Therapy of Tauopathies

open access: yesAdvanced NanoBiomed Research, EarlyView.
A neuron‐targeting drug delivery system is developed by incorporating the tau‐specific N‐amino peptide, mxyl‐NAP2, with graphene quantum dots (GQDs) and encapsulating the complex into small extracellular vesicles functionalized with a neuron‐targeting ligand.

Backbone Protecting Groups for Enhanced Peptide and Protein Synthesis

open access: yesAngewandte Chemie, EarlyView.
This review provides a comprehensive account of the use of backbone N‐protecting groups in peptide synthesis. It includes detailed synthetic methods relating to their introduction and removal and their application to “difficult” peptides and proteins of biological significance in both academic and industry contexts.

Nanostructured Biomaterial‐Based Approaches to Support Induced Pluripotent Stem Cell Differentiation

open access: yesAdvanced NanoBiomed Research, EarlyView.
Induced pluripotent stem cells (iPSCs), reprogrammed from adult somatic cells, represent an innovative approach for regenerative medicine and biomedical applications. This review highlights the importance of nanostructured biomaterials, utilized as delivery systems or scaffolds, in supporting iPSC differentiation and fate through structural and ...
