Investigations of the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents: Part II: Pyridine mono-carboxylic acid N-oxides [PDF]

Journal of the Serbian Chemical Society, 2006
The rate constants for the reaction of three isomeric pyridine mono-carbocylic acid N-oxides with diazodiphenylmethane were determined at 30 ºC in thirty two protic and aprotic solvents by the well known UV spectrophotometric method.

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.

Linear Pentanuclear 3d–4f M‐Gd‐M‐Gd‐M Complexes Prepared From a One‐Pot Reaction Show Intramolecular Ferromagnetic Interactions (M  =  Cu, Ni, and Co)

European Journal of Inorganic Chemistry, EarlyView.
Using a multidentate ligand with two distinct coordination sites and a bridging coordination site, a series of novel linear pentanuclear complexes with alternately arranged 3d and 4f ions via a one‐pot reaction were synthesized. Cryomagnetic studies revealed the presence of intramolecular ferromagnetic interactions and their magnetic entropy changes ...

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 ...

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

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

Inhibition of kynurenine 3‐monooxygenase (KMO) reduces fentanyl and sucrose intake and relapse‐like behaviour in rats

British Journal of Pharmacology, Volume 183, Issue 18, Page 5458-5475, September 2026.
Abstract Background and Purpose Opioid use disorder, particularly involving fentanyl, poses major challenges due to high relapse rates and limited effectiveness of pharmacotherapies. The kynurenine pathway has emerged as a target for addiction treatment through its modulation of glutamatergic and dopaminergic neurotransmission.

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
