Schiff bases : selected syntheses, reactions and biological activity

, 2014
Schiff bases are compounds with a functional group that contains a carbon- -nitrogen double bond with the nitrogen atom connected to an aryl or alkyl group. Schiff bases are condensation products of primary amines with carbonyl compound.

Circulating Amino Acid Network Remodeling Reveals Systemic Metabolic Reprogramming Predictive of Colorectal Cancer Recurrence and Metastasis

Advanced Science, EarlyView.
Blood‐based amino acid patterns measured by 19F NMR reveal hidden metabolic changes in colorectal cancer. By analyzing how these amino acids interact as a network, machine learning models identify patients at higher risk of recurrence and metastasis.

Furfuryl Alcohol‐Driven Proton Supply Enables Efficient Photocatalytic H2O2 Production Beyond Water‐Based Systems

Advanced Science, EarlyView.
A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (
