Solid State and Structural Chemistry Unit, Indian Institute of Science , Bangalore 560 012, India.

A new monoclinic polymorph, form II (P21/c, Z = 4), has been isolated for 3,4-dimethoxycinnamic acid (DMCA). Its solid-state 2 + 2 photoreaction to the corresponding α-truxillic acid is different from that of the first polymorph, the triclinic form I ([Formula: see text], Z = 4) that was reported in 1984. The crystal structures of the two forms are rather different. Read More

Synergistic effects of polyphenols and methylxanthines with Leucine on AMPK/Sirtuin-mediated metabolism in muscle cells and adipocytes.

PLoS One 2014 14;9(2):e89166. Epub 2014 Feb 14.

Research and Development, NuSirt Sciences Incorporated, Knoxville, Tennessee, United States of America.

The AMPK-Sirt1 pathway is an important regulator of energy metabolism and therefore a potential target for prevention and therapy of metabolic diseases. We recently demonstrated leucine and its metabolite β-hydroxy-β-methylbutyrate (HMB) to synergize with low-dose resveratrol (200 nM) to activate sirtuin signaling and stimulate energy metabolism. Here we show that leucine exerts a direct effect on Sirt1 kinetics, reducing its Km for NAD(+) by >50% and enabling low doses of resveratrol to further activate the enzyme (p = 0. Read More

Phenolic acids from wheat show different absorption profiles in plasma: a model experiment with catheterized pigs.

J Agric Food Chem 2013 Sep 9;61(37):8842-50. Epub 2013 Sep 9.

Department of Animal Science, Faculty of Science and Technology, Aarhus University , Blichers Allé 20, PO Box 50, DK-8830 Tjele, Denmark.

The concentration and absorption of the nine phenolic acids of wheat were measured in a model experiment with catheterized pigs fed whole grain wheat and wheat aleurone diets. Six pigs in a repeated crossover design were fitted with catheters in the portal vein and mesenteric artery to study the absorption of phenolic acids. The difference between the artery and the vein for all phenolic acids was small, indicating that the release of phenolic acids in the large intestine was not sufficient to create a porto-arterial concentration difference.
