T Cell‐Independent Role of PD‐L1 in Kidney Repair: Mitigation of Tubular DNA Damage via PD‐L1/BRCA1 Interaction Following AKI

Advanced Science, EarlyView.
PD‐L1 is primarily expressed in renal tubules and upregulated in both murine models of AKI and renal biopsy samples from patients with AKI. PD‐L1 can promote adaptive TECs repair through interacting with BRCA1, independent of its canonical immunomodulatory function of T cells, and PD‐L1 supplementation may represent a promising therapeutic strategy for

Synthesis and Biological Evaluation of New N,N′-Bis(1-substituted-ethylidene)-ethane1,2-diamine and Their Acetyl and Trifluoroacetyl Derivatives as Cytotoxic and Antimicrobial Agents

Journal of Chemistry, 2013
Several Schiff bases 2 have been prepared by the condensation of various methyl ketones 1 with 1,2-ethylenediamine. Subsequent acylation of these Schiff bases with trifluoroacetic anhydride in THF yields the corresponding trifluoroacetyl derivatives 3 ...

G6PC Downregulation Promotes Renal Calcium Oxalate Stone Formation via Lactate‐Induced SNAIL1 K206 Lactylation and Epithelial‐Mesenchymal Transition

Advanced Science, EarlyView.
In renal calcium oxalate stone formation, G6PC downregulation leads to lactate accumulation. This lactate mediates CBP/p300‐dependent lactylation of SNAIL1 at K206, promoting its nuclear translocation. Nuclear SNAIL1 activates the TGF‐β/SMAD3 pathway, driving epithelial‐mesenchymal transition and fibrosis, which ultimately facilitates crystal ...

Schiff Bases Derived from Pyridoxal 5′-Phosphate and 2-X-Phenylamine (X = H, OH, SH): Substituent Effects on UV-Vis Spectra and Hydrolysis Kinetics

Molecules
Schiff bases are compounds that are widely distributed in nature and have practical value for industry and biomedicine. Another important use of Schiff bases is identifying metal ions and different molecules, including proteins.

Reaction of isocyanates with schiff bases

, 2020
1. Electron-donor substituents in the p-positions of the aromatic rings in Schiff bases increase the overall addition rate of the benzoyl and trichloroacetyl isocyanates to Schiff bases and shift the reaction toward the formation of 4-membered rings ...

Mercurated and tellurated Schiff bases and phenylhydrazones

, 1985
Attempts directly to tellurate Schiff bases or phenylhydrazones result in ionic products arising from hydrolysis of tellurium tetrahalides. However use of mercurated Schiff bases and mercurated phenylhydrazones does afford tellurated derivatives on trans-

Tailoring Multifunctional Carbon Dots via Precursor Stoichiometry: Switching Between Solid‐State Fluorescence and Broadband Absorption Through Aggregation Control

Advanced Science, EarlyView.
Precursor stoichiometry programs the surface chemistry of carbon dots, directing their self‐assembly into distinct aggregation modes. Aldehyde‐enriched surfaces form ordered, hydrogen‐bonded assemblies that enable bright red solid‐state fluorescence, whereas amine‐rich surfaces promote compact π–π stacked aggregates with broadband visible‐light ...

Targeting ANGPTL3 and IL‐33/ST2 Ameliorates Diabetic Kidney Disease by Reducing Lipotoxicity, Alleviating Inflammation and Inhibiting Fibrosis

Advanced Science, EarlyView.
Dual targeting of ANGPTL3 and IL‐33/ST2 attenuates diabetic kidney disease by reprogramming lipid–inflammatory crosstalk. This strategy reduces renal lipotoxicity, suppresses inflammatory activation, and limits fibrotic remodeling, thereby preserving kidney structure and function and highlighting a mechanism‐guided therapeutic approach for metabolic ...
