Angewandte Chemie, EarlyView.A consecutive, controllable, and revertible new‐to‐nature ligation and cleavage strategy has been rationally devised to selectively visualize and manipulate biomolecules of interest. The photoclick cycloaddition between allenyl phenyl ether motifs and 9,10‐phenanthrenequinone analogues installed a terminal allyl handle at the exocyclic site, thereby ...

New Transferrin Receptor‐Targeting Conjugate Effectively Delivers DNA to Mouse Brain
Angewandte Chemie, EarlyView.We present a novel RNA aptamer targeting the transferrin receptor (TfR), conjugated with DSPE lipid, which achieves remarkably efficient brain uptake, reaching brain‐to‐serum ratios as high as 6.5. Through fluorescence imaging and polymerase‐chain reaction analyses, we verify that this new conjugate successfully delivers a substantial amount of DNA ...

Toward Autonomous Self‐Healing in Soft Robotics: A Review and Perspective for Future Research
Advanced Intelligent Systems, EarlyView.In this article, five different phases (damage detection, cleaning, damage closure, material healing, and healing assessment) are investigated to have an autonomous self‐healing at the system level with the focus on soft robotics. It delves into the importance of each phase, why and where they matter, and reviews relevant technologies that enable ...

Ribozyme‐Catalyzed Site‐Specific Labeling of RNA Using O6‐alkylguanine SNAP‐Tag Substrates
Angewandte Chemie, EarlyView.SNAPR is a ribozyme that repurposes O6‐benzylguanine SNAP‐tag substrates for site‐specific labeling of RNA with bioorthogonal alkyne and azide functional groups, fluorophores or photocrosslinkers. The N1A‐alkylated RNA products were converted to N6A‐modified RNA by Dimroth rearrangement.

Asian Journal of Organic Chemistry, EarlyView.Phenazinone chromophore incorporating a carbonyl group into the skeleton is recently found to be a new‐type halogen‐atom‐free‐photosensitizer possessing superior ability in singlet oxygen (1O2) generation. In this work, we have designed and developed the derivative with two 5‐formyl‐2‐thienyl substituents which is expected to lead to improvement of the

Angewandte Chemie, EarlyView.Topologically unique, 3D cage‐like noradamantanes are synthesized in one pot from simple starting materials. Catalyzed by diphenylprolinol silyl ether, the reaction followed a domino sequence of Michael/epimerization/Michael/1,2‐addition, achieving excellent enantioselectivity.

Charge-Transfer Forces in the Self-Assembly of Heteromolecular Reactive Solids: Successful Design of Unique (Single-Crystal-to-Single-Crystal) Diels−Alder Cycloadditions [PDF]
, 2001 Electron donor/acceptor (EDA) interactions are found to be a versatile methodology for the engineering of reactive heteromolecular crystals. In this way, a series of the charge-transfer π-complexes between bis(alkylimino)-1,4-dithiin acceptors and ...

Enaminone‐Based Push–Pull Chromophores: Synthesis, Optical Properties, and Computational Insights
Asian Journal of Organic Chemistry, EarlyView.Enaminones, known for their pharmacophoric properties, were combined with alkyne units to create complex chromophore structures through click‐type [2 + 2] cycloaddition‐retroelectrocyclization reactions. The ICT characteristics of the synthesized compounds were analyzed using both experimental and computational approaches.
