NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

Advanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.

Investigation Into The Scope, Limitations, And Mechanistic Aspects Of A Regioselective Acylation Of Cycloplatinated Complexes [PDF]

, 2023
In the reaction of N-isopropyl-N-phenyl-2,2'-bipyridin-6-amine with potassium tetrachloroplatinate, the selective C-H bond activation was complicated by the low selectivity of sp² C-H bond activation in acetonitrile and low yield of sp³ C-H activation in

A Chemically Defined Four‐Component Self‐Adjuvanting Tn Vaccine Activating Mincle, FcγR, and CD206 for Enhanced Antitumor Immunity

Advanced Science, EarlyView.
A fully synthetic four‐component vaccine has been developed combining Tn antigen, vizantin (Mincle agonist), rhamnose (antibody recruitment), and mannose (CD206 targeting). By synergistically activating Mincle, FcγR, and CD206 pathways, it elicits strong IgG switching and cytotoxic T‐cells, significantly inhibiting tumors in mice.

Proteome-scale Analysis of Protein S-acylation Comes of Age

Journal of Proteome Research, 2020
Protein S-acylation (commonly known as palmitoylation) is a widespread reversible lipid modification, which plays critical roles in regulating protein localization, activity, stability, and complex formation.

Calcium‐Mechanochemistry Enabled Ketone Synthesis From Organic Iodides and Carboxylic Acids

Advanced Science, EarlyView.
Mechanochemically generated organocalcium species display unusual chemoselectivity toward carboxylates, enabling direct ketone synthesis without overaddition. Ball milling activates commercial calcium metal under ambient, solvent‐minimized conditions, providing a broad substrate scope, high functional‐group tolerance, and a practical one‐step ...

Effect of Acylation of Flavones with Hydroxycinnamic Acids on their Spectral Characteristics

Natural Product Communications, 2007
The absorption spectra of twenty-one flavones including glycosides of apigenin, luteolin, chrysoeriol and tricin, nonacylated or acylated with coumaric, ferulic or sinapic acids, were examined to document the influence of acylation on their spectral ...

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

Advanced 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 ...
