Introduction: Diabetes mellitus causes adverse changes in the neurological morphology of the hippocampus and prefrontal cortex of the brain by increasing oxidative stress. Trigonelline has antihyperglycemic effects and can inhibit oxidative stress. The aim of this study was to evaluate the protective effect of trigonelline on dendritic changes in hippocampal and prefrontal cortex neurons in dia...

Coffee beans contain two types of alkaloids, caffeine and trigonelline, as major components. This review describes the distribution and metabolism of these compounds. Caffeine is synthesised from xanthosine derived from purine nucleotides. The major biosynthetic route is xanthosine → 7-methylxanthosine → 7-methylxanthine → theobromine → caffeine. Degradation activity of caffeine in coffee plant...

The effects of niacin, namely, nicotinic acid and nicotinamide, and trigonelline on the proliferation and invasion of cancer cells were studied using a rat ascites hepatoma cell line of AH109A in culture. Niacin and trigonelline inhibited the invasion of hepatoma cells at concentrations of 2.5-40 microM without affecting proliferation. Hepatoma cells previously cultured with a reactive oxygen s...

Trigonelline (N-methyl nicotinamide) first gained the attention of plant biologists because it proved to be very effective in inducing G2 arrest in the root apices of many plant species. Although trigonelline, a metabolite of nicotinamide, was put forth as a possible plant hormone over 20 years ago (Evans and Tramontano, 1981), this idea was to gain little acceptance in the ensuing years. Meanw...

Imbibed Arabidopsis (Arabidopsis thaliana) seeds are encapsulated by mucilage that is formed of hydrated polysaccharides released from seed coat epidermal cells. The mucilage is structured with water-soluble and adherent layers, with cellulose present uniquely in an inner domain of the latter. Using a reverse-genetic approach to identify the cellulose synthases (CESAs) that produce mucilage cel...

Arabica and Robusta coffee beans were roasted at 220 ± 10°C for 7, 9 and 11 min to identify chemical descriptors in the beverages. The pH of the beverages showed the lowest value in the medium roasting level. In each degree of browning, the soluble solids content remained slightly higher in Arabica drinks. The contents of caffeine did not vary, but trigonelline decreased with burning up intensi...

OBJECTIVE Coffee consumption has been associated with lower risk of type 2 diabetes. We evaluated the acute effects of decaffeinated coffee and the major coffee components chlorogenic acid and trigonelline on glucose tolerance. RESEARCH DESIGN AND METHODS We conducted a randomized crossover trial of the effects of 12 g decaffeinated coffee, 1 g chlorogenic acid, 500 mg trigonelline, and place...
