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

open access: yesBritish 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.

Synthesis, characterisation and luminescent properties of lanthanide-organic polymers with picolinic and glutaric acids [PDF]

open access: yes, 2007
Three new lanthanide(III) complexes (Ln = Sm, Tb and Eu) of picolinic and glutaric acid were prepared and characterised. The crystal structure of the complex [Sm(glu)(pic)- (H2O)2] (where Hpic and H2glu stand for picolinic and glutaric acid ...

Association Between the Dutch Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND-NL) Diet Adherence and Systemic Tryptophan Metabolites in Older Adults at Risk of Cognitive Decline: An Exploratory Study. [PDF]

open access: yesMol Nutr Food Res
Following the MIND diet may support brain health in older adults at risk of cognitive decline by influencing tryptophan (TRP) metabolism. Plasma samples and dietary intake data from the HELI intervention trial were used. Bivariate latent change score modeling analysis showed that greater adherence to the MIND diet was linked to higher tryptophan levels,
