Nitroquinolones and nitroquinolines: syntheses and antitrypanosomal activity. [PDF]

Mol Divers
Nitroaromatic small molecules are established anti-infectives, including against trypanosomal diseases. Inspired by our previously identified suicide inhibitors of Mycobacterium tuberculosis (Mtb) decaprenylphosphoryl-β-d-ribose 2'-epimerase (DprE1), we report the synthesis and in vitro antitrypanosomal activity of six novel nitroquinoline derivatives (

Interactions of 4-nitroquinoline 1-oxide with four deoxyribonucleotides [PDF]

Biochemistry, 1978
The interactions of 4-nitroquinoline 1-oxide (NQO) with the four 5'-deoxyribonucleotides were probed using absorption spectra of the charge transfer bands and 1H and 13C nuclear magnetic resonance (NMR) spectra of nucleotide-NQO mixtures. Spectral data yielded equilibrium constants (K(dpG:NQO) = 16 M-1, K(dpA:NQO) = 12 M-1, K(dpT:NQO) = K(dpC:NQO) = 4 ...

Scientific Report on consumer health‐based guidance values for trifluoroacetic acid

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to provide a scientific report according to Article 31 of Regulation (EC) No 178/2002, in conjunction with Regulation (EC) No 1107/2009, to revise consumer health‐based guidance values, i.e. acceptable daily intake (ADI) and acute reference dose (ARfD), for trifluoroacetic acid (TFA). EFSA launched a targeted

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

Advanced Science, Volume 13, Issue 35, 24 June 2026.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Conserved Active Site Loop Residues of E. coli DinB and Human DNA Polymerase Kappa Govern Activity

Environmental and Molecular Mutagenesis, Volume 67, Issue 5-7, June‐August 2026.
ABSTRACT DNA damage is ubiquitous and can arise from numerous sources. To mitigate the potential effects of DNA damage, cells possess varied DNA repair and damage tolerance mechanisms. Conserved throughout evolution, specialized DNA damage‐bypass DNA polymerases from the Y family provide DNA damage tolerance. E.

Comprehensive Integrated Single‐Cell and Spatial Transcriptomics Unveil the Dynamic Landscape of Betel Nut‐Associated Oral Mucosal Carcinogenesis and Its Tumor Microenvironment

MedComm, Volume 7, Issue 6, June 2026.
ABSTRACT Betel nut chewing is a major etiological factor for oral squamous cell carcinoma (OSCC), yet its mechanistic underpinnings remain poorly defined. Here, we performed single‐cell RNA sequencing and spatial transcriptomics from six OSCC patients to comprehensively dissect the tumor microenvironment (TME) dynamics and cellular heterogeneity ...

The Lack of a COPII Cargo Receptor Erv14 Impacts Physiological Functions of the Vacuole in Saccharomyces cerevisiae

Traffic, Volume 27, Issue 2, June 2026.
Loss of the cargo receptor Erv14 in Saccharomyces cerevisiae results in sensitivity to calcium, zinc, neutral extracellular pH, and elevated temperature. Furthermore, cells deleted in the ERV14 exhibits vacuolar fragmentation, enlarged lipid droplets, and metabolic alterations. Ruiz Salas, J. L. (2026) https://BioRender.com/b65g523. ABSTRACT Erv14 is a

Activation of the NF‐ĸB Signaling Pathway by Lactobacillus plantarum and Lactobacillus casei Through Modulation of TLR4 and DC‐SIGN Genes in an Oral Squamous Cell Carcinoma Rat Model

Cancer Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background The composition of the oral and intestinal microbiota is believed to contribute to the development of oral cancer (OC). The chronic activation of pattern recognition receptors (PRRs) has been linked to the aggressive nature and poor prognosis of various cancers.

Establishment of a coculture system for Porphyromonas gingivalis and head and neck squamous cell carcinoma using spheroid culture and LATS inhibition

FEBS Open Bio, Volume 16, Issue 4, Page 788-802, April 2026.
We established a spheroid coculture system enabling viable Porphyromonas gingivalis–HNSCC interactions under normoxic conditions. Inhibition of LATS1/2 maintains tumor cells in an undifferentiated state, which may promote spheroid growth and create a more permissive environment for bacterial persistence.

Interfacial Bioengineering of Dynamic Networks Hybrid Hydrogel for Programmed Intervention in Oral Precancerous Epithelial States

Advanced Healthcare Materials, Volume 15, Issue 13, 3 April 2026.
This study develops a dual‐bioinspired hydrogel, MSA@PGel (macrophage membrane‐coated and salvianolic acid B/5‐aminolevulinic acid co‐loaded liposomes embedded in a polydopamine‐based gel), that integrates macrophage membrane‐mediated active targeting and mussel‐inspired wet adhesion for programmed intervention in oral precancerous lesions.
