Small‐Molecule KRAS Inhibitors by Tyrosine Covalent Bond Formation

ChemMedChem, EarlyView.
Small molecules form a covalent bond at KRAS tyrosine and inhibit its activation by guanine exchange factors in biochemical assays and mammalian cells. The development of the KRAS G12C inhibitor sotorasib is a major advance toward drugging KRAS. However, the G12C mutation is only found in about 10% of KRAS‐driven tumors. KRAS possesses several tyrosine

Synthesis, Antimycobacterial Activity and Computational Insight of novel 1,4‐Benzoxazin‐2‐one Derivatives as Promising Candidates Against Multidrug‐Resistant M. tuberculosis

ChemMedChem, Accepted Article.
To search for new antitubercular agents, we have designed, synthesized, and evaluated a series of 1,4‐benzoxazinone‐based compounds. These molecules showed potent antimycobacterial activity, with MIC between 2 and 8 μg/mL. This interesting profile included activity against several drug‐resistant strains and minimal cytotoxicity against mammalian Vero ...

Impact of chelation on reactivity and cytotoxicity of hemilabile biphenyl gold(III) N‐heterocyclic carbene complexes

ChemMedChem, Accepted Article.
Although great progresses have been accomplished in the field of antineoplastic treatments, the need for chemotherapy agents with new mechanisms of action remains essential. Metal complexes presenting hemilabile ligands could combine structural toxicity upon full coordination of the ligand and reactive toxicity upon ligand partial decoordination ...

Advances in Isotope Labeling for Solution Nucleic Acid Nuclear Magnetic Resonance Spectroscopy

ChemPlusChem, EarlyView.
Recent advances in the field of nucleic acid nuclear magnetic resonance (NMR) are presented. Stable isotope labeling protocols and new approaches to segmentally label nucleic acid with NMR‐active residues are summarized. The novel methods will have a strong impact on the future of nucleic acid NMR and the characterization of structure and dynamics of ...

Mercaptans in malodorants break disulfide bridges in human serum albumin and form adducts suitable as biomarkers of exposure in vitro

Drug Testing and Analysis, EarlyView.
Disulfide adducts of mercaptans with cysteine residues in human serum albumin were detected as tripeptides and dipeptides after proteolysis with proteinase K. All peptide adducts were detected simultaneously with a mass spectrometry‐based method working in the scheduled multiple reaction monitoring (sMRM) mode.

Gel Electrophoretic Detection of Black Market ACE‐031

Drug Testing and Analysis, EarlyView.
This article presents a study on black market ACE‐031 products and their detection by gel‐electrophoresis and Western blotting. Of the 14 tested products, only 12 contained an ACVR2B‐immunoreactive protein. However, mass spectrometry revealed that the products did not contain the ACVR2B‐Fc fusion protein ACE‐031 but instead the full‐length human ...

Protein turnover downstream of the Nipbl/CRL4 axis contributes to abnormal development in zebrafish embryos

Developmental Dynamics, EarlyView.
Abstract Background Mutations in cohesins cause cohesinopathies such as Cornelia de Lange Syndrome (CdLS) and Roberts Syndrome (RBS). Prior findings demonstrate that Esco2 (a cohesin activator) and Smc3 (a core cohesin subunit) regulate the CRL4 E3 ubiquitin ligase. SMC3 mutations, however, account for a small percentage of CdLS.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
