Can curcumin supplementation reduce plasma levels of gut-derived uremic toxins in hemodialysis patients? A pilot randomized, double-blind, controlled study

Background Gut dysbiosis is common in patients with chronic kidney disease (CKD) and is closely related to inflammatory processes. Some nutritional strategies, such as bioactive compounds present in curcumin, have been proposed as an option to modulate the gut microbiota and decrease the production of uremic toxins such as indoxyl sulfate (IS), p-cresyl sulfate (pCS) and indole-3 acetic acid (IAA). Objective To evaluate the effects of curcumin supplementation on uremic toxins plasma levels produced by gut microbiota in patients with CKD on hemodialysis (HD). Methods Randomized, double-blind trial in 28 patients [53.6 +/- 13.4 years, fourteen men, BMI 26.7 +/- 3.7 kg/m(2), dialysis vintage 37.5 (12-193) months]. Fourteen patients were randomly allocated to the curcumin group and received 100 mL of orange juice with 12 g carrot and 2.5 g of turmeric and 14 patients to the control group who received the same juice but without turmeric three times per week after HD sessions for three months. IS, pCS, IAA plasma levels were measured by reverse-phase high-performance liquid chromatography Results After three months of supplementation, the curcumin group showed a significant decrease in pCS plasma levels [from 32.4 (22.1-45.9) to 25.2 (17.9-37.9) mg/L, p = 0.009], which did not occur in the control group. No statistical difference was observed in IS and IAA levels in both groups. Conclusion The oral supplementation of curcumin for three months seems to reduce p-CS plasma levels in HD patients, suggesting a gut microbiota modulation.

The key role of protodeauration in the gold-catalyzed reaction of 1,3-diynes with pyrrole and indole to form complex heterocycles

Indole is a very common structural motif in alkaloids, and a number of them feature remarkable bioactive properties. Due to its relevant role in medicinal chemistry and the pharma-industry, many methods for indole synthesis have been developed, but only a few of them exploit the [4 + 2] approach. Recently a successful attempt at indole and carbazole formation via a formal gold mediated [4 + 2] addition of a diyne to pyrrole and indole rings has been reported by Ohno. A number of intriguing features observed in this reaction are however left to be resolved. We study here the mechanism of the Au-catalyzed reaction of 1,3-diynes with pyrrole and indole rings leading to substituted indoles and carbazoles, respectively. The reaction pathways are found to be significantly more complex than we had anticipated, for instance, in the case of the formation of carbazoles, one competitive route involves the formation of an unexpected spirane intermediate that evolves via a 1,2-alkenyl migration. Beyond this complexity, the current study also serves to highlight the importance of fundamental steps that are often disregarded as kinetically irrelevant, such as the protodeauration of reaction intermediates.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1953-54-4, in my other articles.

Heterologous Expression Guides Identification of the Biosynthetic Gene Cluster of Chuangxinmycin, an Indole Alkaloid Antibiotic

The indole alkaloid antibiotic chuangxinmycin, from Actinobacteria Actinoplanes tsinanensis, containing a unique thiopyrano[4,3,2-cd]indole scaffold, is a potent and selective inhibitor of bacterial tryptophanyl-tRNA synthetase. The chuangxinmycin biosynthetic gene cluster was identified by in silico analysis of the genome sequence, then verified by heterologous expression. Systemic gene inactivation and intermediate identification determined the minimum set of genes for unique thiopyrano[4,3,2-cd]indole formation and the concerted action of a radical S-adenosylmethionine protein plus an unknown protein for addition of the 3-methyl group. These findings set a solid foundation for comprehensively investigating the biosynthesis, optimizing yield, and generating new analogues of chuangxinmycin.

The gut microbiota metabolite indole alleviates liver inflammation in mice

The gut microbiota regulates key hepatic functions, notably through the production of bacterial metabolites that are transported via the portal circulation. We evaluated the effects of metabolites produced by the gut microbiota from aromatic amino acids (phenylacetate, benzoate, p-cresol, and indole) on liver inflammation induced by bacterial endotoxin. Precision-cut liver slices prepared from control mice, Kupffer cell (KC)-depleted mice, and obese mice (ob/ob) were treated with or without LPS and bacterial metabolites. We observed beneficial effects of indole that dose-dependently reduced the LPS-induced up-regulation of proinflammatory mediators at both mRNA and protein levels in precision-cut liver slices prepared from control or ob/ob mice. KC depletion partly prevented the antiinflammatory effects of indole, notably through a reduction of nucleotide-binding domain and leucine-rich repeat containing (NLR) family pyrin domain-containing 3 (NLRP3) pathway activation. In vivo, the oral administration of indole before an LPS injection reduced the expression of key proteins of the NF-B pathway and downstream proinflammatory gene up-regulation. Indole also prevented LPS-induced alterations of cholesterol metabolism through a transcriptional regulation associated with increased 4-hydroxycholesterol hepatic levels. In summary, indole appears as a bacterial metabolite produced from tryptophan that is able to counteract the detrimental effects of LPS in the liver. Indole could be a new target to develop innovative strategies to decrease hepatic inflammation.Beaumont, M., Neyrinck, A. M., Olivares, M., Rodriguez, J., de Rocca Serra, A., Roumain, M., Bindels, L.

Arenesulfonyl indole: new precursor for diversification of C-3 functionalized indoles

Arenesulfonyl indoles, bearing a good leaving group, are effective precursors for vinylogous imine intermediates which are generated in situ under basic conditions. This intermediate can readily react with other nucleophilic reagents to obtain C-3 substituted indole derivatives. In the last few years, a plethora of exciting synthetic applications of this substrate have been exploited. The stability of arylsulfonyl-containing substrates, mild reaction conditions, and the large variety of nucleophiles involved in these procedures are the key to their success in organic synthesis.

Synthesis and evaluation of some novel 3-hetarylindole derivatives as antimicrobial and antioxidant agents

In a continuation of our program to develop a new class of antimicrobial and antioxidant agents, 13 novel 3-substituted indole derivatives incorporating biologically active heterocycles were synthesized and evaluated for their in vitro antimicrobial activity. Among the synthesized compounds, 3-(7H-imidazo[2,1-c][1,2,4]triazol-5-yl)-1H-indole showed activity against E. faecalis equal to that of ampicillin and 50% higher activity than ampicillin against S. aureus and B. subtilis. Also, 3-(7H-imidazo[2,1-c][1,2,4]triazol-5-yl)-1H-indole was found to exhibit strong in vitro antifungal activity against Candida albicans, Aspergillus niger, and Penicillium sp. The antioxidant activity of the obtained indole derivatives was also studied using 2,2′-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid).

Flavonol-mediated stabilization of PIN efflux complexes regulates polar auxin transport

The transport of auxin controls the rate, direction and localization of plant growth and development. The course of auxin transport is defined by the polar subcellular localization of the PIN proteins, a family of auxin efflux transporters. However, little is known about the composition and regulation of the PIN protein complex. Here, using blue-native PAGE and quantitative mass spectrometry, we identify native PIN core transport units as homo- and heteromers assembled from PIN1, PIN2, PIN3, PIN4 and PIN7 subunits only. Furthermore, we show that endogenous flavonols stabilize PIN dimers to regulate auxin efflux in the same way as does the auxin transport inhibitor 1-naphthylphthalamic acid (NPA). This inhibitory mechanism is counteracted both by the natural auxin indole-3-acetic acid and by phosphomimetic amino acids introduced into the PIN1 cytoplasmic domain. Our results lend mechanistic insights into an endogenous control mechanism which regulates PIN function and opens the way for a deeper understanding of the protein environment and regulation of the polar auxin transport complex.
