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.

Synthetic strategies for preparing BEDT-TTF derivatives functionalised with metal ion binding groups [PDF]

, 2006
The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups are achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and ...

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.

Vanadyl complexes with dansyl-labelled dipicolinic acid ligands: synthesis, phosphatase inhibition activity and cellular uptake studies [PDF]

, 2016
Vanadium complexes have been previously utilised as potent inhibitors of cysteine based phosphatases (CBPs). Herein, we present the synthesis and characterisation of two new fluorescently labelled vanadyl complexes (14 and 15) with bridged di-picolinic ...

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

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

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 ...
