A Small‐Molecule DEPTAC Rescues Cognitive Deficits by Targeted Dephosphorylation of Pathological Tau

Advanced Science, EarlyView.
TP2 is a fully synthetic small‐molecule dephosphorylation‐targeting chimera that recruits endogenous PP2A‐Bα to Tau, enabling targeted removal of pathological phosphate modifications. In two tauopathy mouse models, systemic TP2 reduces Tau pathology, preserves neuronal and synaptic integrity, improves neuroimmune homeostasis, and rescues cognition ...

Efficient and selective N-alkylation of amines with alcohols catalysed by manganese pincer complexes

Nature Communications, 2016
Hydrogen borrowing is an attractive method for C-N bond formation - avoiding multiple alkylation products and reducing waste - but often is carried out with noble metals.

The Usefulness of Trivalent Phosphorus for the Synthesis of Dendrimers

Molecules, 2021
Dendrimers are hyperbranched macromolecules, which are synthesized step-by-step by the repetition of a series of reactions. While many different types of dendrimers are known, this review focusses on the use of trivalent phosphorus derivatives ...

Photobiomodulation‑Engineered Extracellular Vesicles Enhance Neural Differentiation via UFL1‑Mediated UFMylation in Spinal Cord Injury

Advanced Science, EarlyView.
Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

Reaction of Some Substituted (Un)Substituted Isatins with 1,ω-Alkanes and Their Products with Sodium Azide

Chemistry Proceedings, 2021
Azide derivatives of isatins were the initial materials needed for click chemistry, so as to form 1,2,3-triazoles in order to synthesize the hybrid compounds of 1,2,3-triazole–isatin with monosaccharide moieties.

Overcoming Drug Resistance by Paclitaxel Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
In the murine triple‐negative breast cancer (TNBC) model, chemotherapy effectively increases tumor neoantigen burden (TNB). Here, the study constructs a liposomal nanovaccine using antigens derived from in vitro chemotherapy‐treated paclitaxel‐resistant TNBC 4T1 cells.

Low SLC8A1 in Colorectal Cancer Dictates Radiotherapy Resistance Through Calcium‐Dependent ANXA2+sEVs Driving M2 Polarization of TAMs

Advanced Science, EarlyView.
SLC8A1 deficiency in colorectal cancer cells increases intracellular calcium signaling, promoting the secretion of ANXA2‐enriched small extracellular vesicles. These vesicles reprogram tumor‐associated macrophages towards an M2 phenotype, which in turn fosters a tumor microenvironment conducive to radioresistance and is associated with poor patient ...

The Mitogen‐Activated Protein Kinase GhNTF3 Modulates the Arbuscular Mycorrhizal Symbiosis‐Immunity Trade‐Off in Cotton by Regulating Salicylic Acid Biosynthesis

Advanced Science, EarlyView.
AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...

Alkylating Agents Stronger than Alkyl Triflates [PDF]

Journal of the American Chemical Society, 2004
A new class of potent electrophilic "R(+)" alkylating agents has been developed using weakly nucleophilic carborane anions as leaving groups. These reagents, R(CHB(11)Me(5)X(6)) (R = Me, Et, and i-Pr; X = Cl, Br), are prepared via metathesis reactions with conventional alkylating agents such as alkyl triflates, using the high oxophilicity of silylium ...
