Full textMigraine is a neurological disorder that affects over a billion individuals globally, primarily women. In 3% of patients, the frequency of migraine attacks increases, and from episodic, the migraine becomes chronic. The mechanisms of this chronicization are still uncertain, and migraine is still a tough condition to treat. Recent studies have suggested the involvement of L-tryptophan (L-Trp), an essential amino acid, and its metabolites in the pathophysiology of migraine. Indeed, deprivation of L-Trp aggravates the intensity of headaches, while its regular intake reduces the risk of attack. Our aim is to underatand the mechanism of the effect of Trp deregulation in migraine. To study the contribution of L-Trp in the chronicization of migraine as well as in the appearance of associated sensory symptoms (mechanical allodynia and photophobia) and the comorbidity of migraine with psychiatric disorders (depression and anxiety). In addition, we explore the effect of L-Trp deficit on the efficacy of currently established anti-migraine medications

Full textTryptophan, an essential amino acid, both functions as a building block in protein biosynthesis and as a biochemical precursor. It is abundantly found in most biologically active peptides that exhibit various physiological properties in particular hormonal and antimicrobial activities. Some of its natural derivatives like serotonin, tryptamine, and also unnatural derivatives such as sumatriptan, have neurophysiologic effects. Tryptophan analogues are also important building blocks for the synthesis of peptidomimetics, natural products and biologically active compounds. Another important property of tryptophan and tryptophan analogues is related to the fluorescence of the indole ring that can be used to study conformational changes in protein and in protein-membrane interactions. The asymmetric Friedel-Crafts alkylation of various indoles with a chiral nitroacrylate provides optically active beta-tryptophan analogues after reduction of the nitro group and removal of the chiral auxiliary. This reaction generally occurs in good yield and high diastereoselectivity (up to 90:10). We have established a new route to prepare enantiopure beta-tryptophan analogues ((S)-2-indolyl-beta-alanines). We showed that beta-nitroacrylate (R)-2 is a good chiral auxiliary for asymmetric Friedel-Crafts alkylation of indoles. (R)-2-indolyl--alanines were obtained by the same synthetic route by using the chiral compound (S)-2. beta-tryptophan analogues are delivered in their N-Fmoc-protected form, ready to use for instance in solid phase peptide synthesis, which is one of the most popular method for peptide synthesis. This study provides a new example of asymmetric beta-tryptophan analogues preparation and further studies concerning their applications in medicinal chemistry and in organic synthesis are now in progress

Full textTryptophan, an essential amino acid, is either used in protein synthesis or metabolized via the serotonin or the kynurenine pathway. The kynurenine pathway is the main route of tryptophan degradation and generates several metabolites collectively called “kynurenines”. The expression of kynurenine pathway enzymes is induced by inflammatory mediators. Consequently kynurenine synthesis could be induced in individuals with obesity. In fact, obesity is characterized by a chronic low grade inflammation of the adipose tissue reflected by increased serum levels of inflammatory factors which are known to contribute to the development of obesity-induced insulino-resistance. Some metabolites of the kynurenine pathway have been proposed to be risk factors for the development of insulin resistance. Bariatric surgery is currently the most effective treatment for severe obesity and results in a significant weight loss, a decreased level of inflammatory factors and an amelioration of glucose homeostasis. The first enzyme of the kynurenine pathway, IDO1, is known to be more expressed in the adipose tissue of individuals with obesity compared to lean individuals. The kynurenine over tryptophan ratio reflects the activity of IDO1 and is also increased in individuals with obesity.Our objective was to characterize the expression of the kynurenine pathway enzymes in the adipose tissue of women with severe obesity and to evaluate serum levels of the kynurenine pathway metabolites to determine whether these factors could be associated with the appearance of diabetes. This study was performed in women with severe obesity with or without type 2 diabetes. Then we investigated the consequences of weight loss induced by bariatric surgery on levels of circulating kynurenines in order to evaluate whether these variations could explain the improvement in glucose control and type 2 diabetes remission after one year follow-up.In this study, we have shown that several kynurenine pathway enzymes were more expressed in the adipose tissue of women with obesity compared to lean controls. This increase is due to the presence of pro-inflammatory macrophages in the adipose tissue and also comes from the adipocyte response to inflammatory stimuli. In addition, we observed that the serum level of kynurenine and kynurenine over tryptophan ratio are higher in women with higher BMI and they both decrease one year after bariatric surgery. In addition, we observed that the serum level of kynurenine and kynurenine over tryptophan ratio are higher in women with higher BMI and they both decrease one year after bariatric surgery. As expected, bariatric surgery is associated with the improvement and even the remission of type 2 diabetes. We have shown that higher levels of kynurenic acid and quinolinic acid one year after the surgery are associated respectively with type 2 diabetes remission and better glucose homeostasis and that lower levels of xanthurenic acid are associated with better glucose homeostasis
