Dietary curcumin and limonin suppress murine CD4 + T‐cell activation

Dietary curcumin and limonin suppress CD4+ T-cell proliferation and interleukin-2 production in mice.

Phytochemicals may reduce chronic inflammation and cancer risk in part by modulating T-cell nuclear factor-kappaB (NF-kappaB) activation. Therefore, we examined the effects of curcumin (Cur) and limonin (Lim) feeding on NF-kappaB-dependent CD4(+) T-cell proliferation. DO11.10 transgenic mice (n = 5-7) were fed diets containing 1% Cur or 0.02% Lim combined with either (n-6) PUFA [5% corn oil (CO...

Curcumin prevents and reverses murine cardiac hypertrophy.

Chromatin remodeling, particularly histone acetylation, plays a critical role in the progression of pathological cardiac hypertrophy and heart failure. We hypothesized that curcumin, a natural polyphenolic compound abundant in the spice turmeric and a known suppressor of histone acetylation, would suppress cardiac hypertrophy through the disruption of p300 histone acetyltransferase-dependent (p...

Total Synthesis of Limonin.

Limonoids are highly oxygenated C13α-triterpenes and common secondary metabolites. Several hundred congeners have been isolated to date. The first total synthesis of (±)-limonin, the flagship congener of the limonoids, is now reported and features 1) a tandem radical cyclization generating the BCD ring system with the C13α configuration that is essential to the limonoids and a Robinson annulati...

Curcumin attenuates DNB-induced murine colitis.

Numerous therapies used for inflammatory bowel disease (IBD) target the transcription factor NF-kappaB, which is involved in the production of cytokines and chemokines integral for inflammation. Here we show that curcumin, a component of the spice turmeric, is able to attenuate colitis in the dinitrobenzene sulfonic acid (DNB)-induced murine model of colitis. When given before the induction of ...
