RELAXATION OF ISOLATED AORTA OF THE RABBIT BY PICOLINIC ACIDS [PDF]

open access: bronzeBritish Journal of Pharmacology, 1977
When the isolated thoracic aorta of the rabbit was contracted with prostaglandin F2α, 5‐alkylpicolinic acids produced dose‐dependent relaxations. Picolinic acid, 2,5‐pyridinedicarboxylic acid and 5‐acetylpicolinic acid which do not have the 5‐alkyl residue failed to relax blood vessels.

Redetermination of picolinic acid hydrochloride at 150 K

open access: greenActa Crystallographica Section E Structure Reports Online, 2007
The structure of the title compound, C6H6NO2+·Cl−, was previously determined at ambient temperature [Laurent (1965). Acta Cryst. 18, 799–806]. This redetermination at 150 K is to a far higher precision. On cooling to 150 K, the unit cell contracts most in the π–π stacking direction, b, and rather less so in the directions involving the strongly ...

Preparation and diagnosis of new picolinic acid derivatives

open access: yesTikrit Journal of Pure Science, 2023
In this study, a new series of heterocyclic rings derived from picolinic acid was prepared. The quaternary reaction of acid hydrazone with chloroacetyl chloride was intended to obtain the azitidine-2-on ring known as beta-lactam and the preparation of ...

Gestational kynurenine metabolites mediate effects of pregnancy adiposity on child negative affect. [PDF]

open access: yesJ Child Psychol Psychiatry
Background Mounting evidence links increased adiposity during pregnancy and offspring risk for mental health disorders. Yet the mechanisms underlying this association remain poorly understood, limiting our ability to design effective interventions.

M. tuberculosis induces potent activation of IDO-1, but this is not essential for the immunological control of infection. [PDF]

open access: yesPLoS ONE, 2012
Indoleamine 2,3-dioxygenesae-1 (IDO-1) catalyses the initial, rate-limiting step in tryptophan metabolism, thereby regulating tryptophan availability and the formation of downstream metabolites, including picolinic and quinolinic acid.

Suppression of Dissolution Rate via Coordination Complex in Tungsten Chemical Mechanical Planarization

open access: yesApplied Sciences, 2022
Topography of tungsten should be assured at a minimum through chemical mechanical planarization (CMP) in the metal gate structures (e.g., buried gates, replacement metal gates) and via contact in the middle of line (MOL) process for sub−7 nm ...
