Electrospray ionization tandem mass spectrometry of monoketone curcuminoids [PDF]
Rapid Communications in Mass Spectrometry, 2020 RationaleAlthough monoketone curcuminoids (MKCs) have been largely investigated due to their biological activities, data on the gas‐phase fragmentation reactions of protonated MKCs under collision‐induced dissociation (CID) conditions are still scarce.

Molecular Oncology, EarlyView.B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Prospects in Analytical Atomic Spectrometry [PDF]
Russian Chemical Reviews, v. 75, pp. 289-302 (2006). [Translated
from Uspekhi Khimii, v. 75, pp. 322-338 (2006)], 2006 Tendencies in five main branches of atomic spectrometry (absorption, emission, mass, fluorescence and ionization spectrometry) are considered. The first three techniques are the most widespread and universal, with the best sensitivity attributed to atomic mass spectrometry.

Identification of inhibitors of the Salmonella FraB deglycase, a drug target
FEBS Open Bio, EarlyView.A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis
Advanced Biology, EarlyView.Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,
