Polymorphism in the 1/1 Pterostilbene/Picolinic Acid Cocrystal. [PDF]
Cryst Growth Des, 2022 The crystal structures of two new polymorphs of the 1/1 pterostilbene/picolinic acid cocrystal have been analyzed by single-crystal X-ray diffraction and studied by means of DFT calculations and a set of computational tools (QTAIM, NCIplot, MEP). The observation of a new R2 2(10) synthon in each of the two polymorphs has been analyzed energetically ...

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

A novel derivative of picolinic acid induces endoplasmic reticulum stress-mediated apoptosis in human non-small cell lung cancer cells: synthesis, docking study, and anticancer activity [PDF]
Pharmacia, 2021 Thirteen new derivatives of picolinic acid (4–7) were designed and synthesized from the starting parent molecule, picolinic acid. The new compounds were characterized by ATR-FTIR, 1HNMR, and CHNS analysis.

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