Three‐Component Synthesis of γ‐Amino Esters with α‐Quaternary Carbon Centers via NHC/Photoredox Dual Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
γ‐Amino acid derivatives with an α‐quaternary center are prevalent in medicinally important compounds. A dual N‐heterocyclic carbene/photocatalytic pathway is developed for the three‐component synthesis of α, α ‐disubstituted γ‐amino esters. This methodology allows for the rapid synthesis of diverse libraries of γ‐amino esters in good yields.

The structure of Chlamydomonas LOV1 as revealed by time-resolved serial synchrotron crystallography

open access: yesIUCrJ
The photo-reaction of the LOV1 domain of the Chlamydomonas reinhardtii phototropin is investigated by room-temperature time-resolved serial crystallography. A covalent adduct forms between the C4a atom of the central flavin-mononucleotide chromophore and

Electrochemical Chemo‐ and Regioselective Heterofunctionalization of Tropones via C(sp2)H Derivatization

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Simple and selective. The electrochemical heterofunctionalization of activated tropones is achieved using readily available inorganic salts. A theoretical model, based on cyclic voltammetry and quantum chemistry calculations, predicts both reactivity trends and site selectivity.

Reaction of Proton Pump Inhibitors With Model Peptides Results in Novel Products

open access: yesJournal of Pharmacological Sciences, 2013
The proposed mechanism for proton pump inhibitors (PPIs) is that PPIs are activated at low pH to the sulfenamide form, which reacts with the sulfhydryl group of cysteine(s) at the active site of the proton pump, to produce reducible disulfide-bonded PPI ...

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

open access: yesAdvanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

open access: yesAdvanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.
