Autoantigen mRNA‐LNP Vaccination Drives Therapeutic Efficacy in Preclinical Models for Autoimmunity

open access: yesAdvanced Science, EarlyView.
Systemic and intramuscular delivery of autoantigen mRNA via lipid nanoparticles reprograms antigen‐presenting cells toward a mature, homeostatic state, driving antigen‐specific T cell exhaustion and providing therapeutic efficacy across autoimmune disease models.

Arrangement of Azidomethyl Group in Lupinine Azide: Structural and Spectroscopic Properties

open access: yesMolecules
Quinolizidine derivatives are an important class of substances that are used in the pharmaceutical industry. In previous studies, the synthesis of these substances is carried out using lupinine azide (IUPAC: 1-(azidomethyl)octahydro-2H-quinolizine ...

Artificial Host‐Guest Recognition Directs Glycometabolically Engineered Macrophages to Tumors

open access: yesAdvanced Science, EarlyView.
Glycoengineered supramolecular macrophages (GSAR‐M) are developed using glycometabolic labeling for bioorthogonal host‐guest tumor targeting. This engineering approach unexpectedly enhances macrophage migration, phagocytosis, and pseudopodia formation. Consequently, GSAR‐M demonstrate robust tumor‐targeting specificity, effectively arrest tumor growth,

The Azide‐Wittig Reaction

open access: yesAngewandte Chemie International Edition
AbstractThe introduction of heteroatoms into conjugated organic molecules is an important strategy to tune their reactivity and physical properties. In this realm triazabutadienes (TBDs) of the general from R2C=N−N=NR’ are an interesting class of compounds, however, general synthetic protocols for their generation are limited.

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

open access: yesAdvanced Science, EarlyView.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

PEG 400 promoted nucleophilic substitution reaction of halides into organic azides under mild conditions

open access: yes, 2011
Polyethylene glycol 400 (PEG 400) has been demonstrated as an efficient and eco-friendly reaction medium for the preparation of organic azides from structurally diverse halides by nucleophilic substitution reaction with NaN(3) under mild conditions.

Dual Blockade of LILRB1 and LILRB2 Enhances Antiviral Immune Responses in SIV Infection

open access: yesAdvanced Science, EarlyView.
Dual LILRB1/B2 blockade with mac20G10 reshapes myeloid activation during acute SIV infection by targeting LILRB1 and LILRB2 on myeloid cells. This treatment enhances CD80 expression on selected myeloid subsets and increases plasma IFN‐λ, IL‐8, and IL‐1RA.

Aspects of the chemistry of some highly crowded aromatic ligands [PDF]

open access: yes, 1990
A series of ortho-substituted arylchlorophosphoranes has been prepared. The structures of these compounds have been studied by the use of (^31)Cl n.q.r. and solid-state (^31)P n.m.r. . It has been shown that ortho substitution by groups such as CH(_3) or

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

open access: yesAdvanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Glycosyl azides - An alternative way to disaccharides

open access: yes, 2007
Glycosyl azides are shown to be efficient donors for b-galactosidases, b-glucosidases and a-mannosidases. Only a-galactosidases do not cleave the respective glycosyl azide 1 and, moreover, they exhibit competitive inhibition (especially a ...
