Picolinic acid, a catabolite of tryptophan, as the second signal in the activation of IFN-gamma primed macrophages.

, 1990
We have studied the effects of picolinic acid, a product of tryptophan degradation, on the activation of mouse peritoneal macrophages (M phi). Picolinic acid acts synergistically with IFN-gamma in activating M phi from C57BL/6 mice.

Picolinic and Isonicotinic Acids: A Fourier Transform Microwave Spectroscopy Study

, 2016
The rotational spectra of laser ablated picolinic and isonicotinic acids have been studied using broadband chirped pulse (CP-FTMW) and narrowband molecular beam (MB-FTMW) Fourier transform microwave spectroscopies. Two conformers of picolinic acid, s-cis-

Ferric Reducing, Antiradical and β-Carotene Bleaching Activities of Nicotinic Acid and Picolinic Acid Bioconjugates of Curcumin

Natural Product Communications, 2011
Although curcumin displays several beneficial properties, its medicinal use is limited by its low bioavailability. In the present study we report the antioxidant potentials of two bioconjugates of curcumin with nicotinic acid and picolinic acid: di- O ...
