X-Ray structure and cytotoxic activity of a picolinate ruthenium(II)–arene complex [PDF]

Journal of the Serbian Chemical Society, 2011
A ruthenium(II)–arene complex with picolinic acid, [(η6-p-cymene)RuCl(pico)]∙H2O, was prepared by the reaction of [(η6-p-cymene)RuCl2]2 with picolinic acid in a 1:2 molar ratio in 2-propanol.

The mediating role of the kynurenine pathway in longitudinal associations between dietary intake and quality of life in colorectal cancer survivors up to 12 months posttreatment

International Journal of Cancer, EarlyView.
What's New? Many colorectal cancer survivors experience reduced health‐related quality of life (HRQoL), often lasting years after diagnosis. Healthy dietary patterns and even individual macro‐ and micronutrients, however, can potentially improve HRQoL.

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, EarlyView.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Clinical relevance of depressed kynurenine pathway in episodic migraine patients: potential prognostic markers in the peripheral plasma during the interictal period

The Journal of Headache and Pain, 2021
Background Altered glutamatergic neurotransmission and neuropeptide levels play a central role in migraine pathomechanism. Previously, we confirmed that kynurenic acid, an endogenous glutamatergic antagonist, was able to decrease the expression of ...

Picolinic and Isonicotinic Acids: A Fourier Transform Microwave Spectroscopy Study [PDF]

The Journal of Physical Chemistry A, 2014
The rotational spectra of laser ablated picolinic and isonicotinic acids have been studied using broadband chirped pulse (CP-FTMW) and narrowband molecular beam (MB-FTMW) Fourier transform microwave spectroscopies. Two conformers of picolinic acid, s-cis-I and s-cis-II, and one conformer of isonicotinic acid have been identified through the analysis of

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Differential Analysis of IAA Anabolism Pathway Based on Bacillus cereus, Bacillus subtilis and Bacillus safensis Genome

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Three Bacillus species isolated from Platycladus orientalis rhizosphere in Taihang Mountains: Bacillus cereus has 3 IAA synthesis pathways (TAM, IAM, IPyA); Bacillus subtilis has IAM/IPyA; and Bacillus safensis only has IPyA (via whole‐genome sequencing).

Similarity Between the Action of Pteridines and Tryptophan Metabolites on Lipid Metabolism

Pteridines, 1999
Incorporation of fatty acids into phospholipids has been investigated using samples of rat liver tissue homogenate, Krebs-Ringer-phosphate buffer (pH=7.4) containing 0.3% albumin, fatty acid mixture and glycerol. The addition of anthranilic acid (2.2 and
