Fermented barley extract supplementation ameliorates metabolic state in stroke-prone spontaneously hypertensive rats.

We studied the effects of fermented barley extract P (FBEP) in stroke-prone spontaneously hypertensive rats (SHRSP). Male 10-week-old SHRSP were divided into three groups that were fed: an AIN-93M diet (control), a low dose of FBEP (4 g/kg; FBEP1), and a high dose of FBEP (20 g/kg; FBEP2) for three weeks. Hypertension was significantly improved by the use of FBEP supplementation.

Systematic synthesis and anti-inflammatory activity of ω-carboxylated menaquinone derivatives--Investigations on identified and putative vitamin K₂ metabolites.

Vitamin K is an essential nutrient for blood coagulation and bone homeostasis, and also functions in many physiological processes including inflammation and cancer progression. However, the nature and activities of its metabolites remain unclear. We report here systematic synthesis of ω-carboxylated derivatives of menaquinone (vitamin K2), including previously identified metabolites 5, K acid I (10), and K acid II (12), and evaluation of their inhibitory activity toward LPS-stimulated induction of inflammatory cytokines.
