Study on Design, Synthesis and Herbicidal Activity of Novel 6-Indazolyl-2-picolinic Acids

open access: yesMolecules
Thirty-eight new 4-amino-3,5-dicholo-6-(1H-indazolyl)-2-picolinic acids and 4-amino-3,5-dicholo-6-(2H-indazolyl)-2-picolinic acids were designed by scaffold hopping and synthesized to discover potential herbicidal molecules.

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.
