Chiral and Chirality Discrimination on Helical Polyacetylenes
Analytical Sciences, 2002 Synthesis and function of helical polyphenylacetylenes are briefly reviewed. Optically active helical polyphenylacetylenes were synthesized by polymerization of the corresponding chiral phenylacetylene monomers and their chiral recognition abilities were evaluated as a chiral stationary phase for HPLC.

Advanced Functional Materials, EarlyView.A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets
Advanced Science2D chiral magnets are known to host a variety of skyrmions, characterized by an integer topological charge (Q∈Z). However, these systems typically favor uniform lattices as thermodynamically stable phases composed of either skyrmions (Q = −1) or ...

Enantioselectivity of Chiral Derivatives of Xanthones in Virulence Effects of Resistant Bacteria
Pharmaceuticals, 2021 Antimicrobial peptides are one of the lines of defense produced by several hosts in response to bacterial infections. Inspired by them and recent discoveries of xanthones as bacterial efflux pump inhibitors, chiral amides with a xanthone scaffold were ...

Advanced Functional Materials, EarlyView.We present a novel proteolysis‐targeting chimera (PROTAC) system conjugated to lipoic acid gold nanoclusters (PLANC), designed to degrade pTau, regulate inflammatory signaling, and effectively traverse the blood‐brain barrier (BBB). PLANC degraded pTau at various phosphorylation sites, with mechanistic studies confirming proteasome‐mediated degradation

Chiral Peptide Nucleic Acids with a Substituent in the N-(2-Aminoethy)glycine Backbone
Molecules, 2012 A peptide nucleic acid (PNA) is a synthetic nucleic acid mimic in which the sugar-phosphate backbone is replaced by a peptide backbone. PNAs hybridize to complementary DNA and RNA with higher affinity and superior sequence selectivity compared to DNA ...
