Dietary fibre intake is low in paediatric chronic kidney disease patients but its impact on levels of gut-derived uraemic toxins remains uncertain

Background Chronic kidney disease (CKD) in children is a pro-inflammatory condition leading to a high morbidity and mortality. Accumulation of organic metabolic waste products, coined as uraemic toxins, parallels kidney function decline. Several of these uraemic toxins are protein-bound (PBUT) and gut-derived. Gut dysbiosis is a hallmark of CKD, resulting in a state of increased proteolytic fermentation that might be counteracted by dietary fibre. Data on fibre intake in children with CKD are lacking. We aimed to assess dietary fibre intake in a paediatric CKD cohort and define its relationship with PBUT concentrations. Methods In this multi-centre, cross-sectional observational study, 61 non-dialysis CKD patients (9 +/- 5 years) were included. Dietary fibre intake was assessed through the use of 24-h recalls or 3-day food records and coupled to total and free levels of 4 PBUTs (indoxyl sulfate (IxS), p-cresyl sulfate (pCS), p-cresyl glucuronide (pCG) and indole acetic acid (IAA). Results In general, fibre intake was low, especially in advanced CKD: 10 +/- 6 g/day/BSA in CKD 4-5 versus 14 +/- 7 in CKD 1-3 (p = 0.017). Lower concentrations of both total (p = 0.036) and free (p = 0.036) pCG were observed in the group with highest fibre intake, independent of kidney function. Conclusions Fibre intake in paediatric CKD is low and is even worse in advanced CKD stages. Current dietary fibre recommendations for healthy children are not being achieved. Dietary management of CKD is complex in which too restrictive diets carry the risk of nutritional deficiencies. The relation of fibre intake with PBUTs remains unclear and needs further investigation.

Oleanolic acid indole derivatives as novel alpha-glucosidase inhibitors: Synthesis, biological evaluation, and mechanistic analysis

Research efforts have been directed to the development of oleanolic acid (OA) based alpha-glucosidase inhibitors and various OA derivatives showed improved anti-alpha-glucosidase activity. However, the inhibitory effects of indole infused OA derivatives on alpha-glucosidase is unknown. Herein, we synthesized a series of indole-OA (2a-2o) and -OA methyl ester (3a-3 1) derivatives with various electron withdrawing groups inducted to indole benzene ring and evaluated their anti-alpha-glucosidase activity. Indole OA derivatives (2a-2o) exhibited superior alpha-glucosidase inhibitory effects as compared to OA methyl ester derivatives (3a-31) and OA (with IC50 values of 4.02 mu M-5.30 mu M v.s. over 10 mu M and 5.52 mu M, respectively). In addition, mechanistic studies using biochemical (kinetic assay), biophysical (circular dichroism), and computational (docking) methods revealed that OA-indole derivatives (2a and 2f) are mixed type of alpha-glucosidase inhibitors and their inhibitory effects were attributed to their capacity of forming the ligand-enzyme complex with alpha-glucosidase enzyme. Findings from this study support that OA indole derivatives are promising alpha-glucosidase inhibitors as a potential management of diabetes mellitus.

Structure-based discovery of 1H-indole-2-carboxamide derivatives as potent ASK1 inhibitors for potential treatment of ulcerative colitis

Apoptosis signal-regulating kinase 1 (ASK1), a member of the mitogen-activated protein kinase (MAPK) family, is implicated in many human diseases. Here, we describe the structural optimization of hit compound 7 and conduct further structure-activity relationship (SAR) studies that result in the development of compound 19 with a novel indole-2-carboxamide hinge scaffold. Compound 19 displays potent anti-ASK1 kinase activity and stronger inhibitory effect on ASK1 in AP1-HEK293 cells than previously described ASK1 inhibitor GS-4997. Besides improved in vitro activity, compound 19 also exhibits an appropriate in vivo PK profile. In a dextran sulfate sodium (DSS)-induced mouse model of ulcerative colitis (UC), compound 19 shows significant anti-UC efficacy and markedly attenuates DSS-induced body weight loss, colonic shortening, elevation in disease activity index (DAI) and inflammatory cell infiltration in colon tissues. Mechanistically, compound 19 represses the phosphorylation of ASK1-p38/JNK signaling pathways and suppresses the overexpression of inflammatory cytokines. Together, these findings suggest that ASK1 inhibitors can potentially be used as a therapeutic strategy for UC. (C) 2020 Elsevier Masson SAS. All rights rights reserved.

Crystal structure of the acyl acid amido synthetase GH3-8 from Oryza sativa

The Gretchen Hagen 3 (GH3) family of acyl acid amido synthetases regulate the levels and activities of plant hormones containing carboxyl groups, thereby modulating diverse physiological responses. While structure-function relationships have been elucidated for dicotyledonous GH3s, the catalytic mechanism of monocotyledonous GH3 remains elusive. Rice (Oryza sativa) is a representative monocot, and its yield is controlled by the natural growth hormone IAA (indole-3-acetic acid). OsGH3-8 is a model GH3 enzyme that conjugates excess IAA to amino acids in an ATP-dependent manner, ensuring auxin homeostasis and regulating disease resistance, growth and development. Here, we report the crystal structure of OsGH3-8 protein in complex with AMP to uncover the molecular and structural basis for the activity of monocotyledonous GH3-8. Structural and sequence comparisons with other GH3 proteins reveal that the AMP/ATP binding sites are highly conserved. Molecular docking studies with IAA, the GH3-inhibitor Adenosine-5′-[2-(1H-indol-3-yl)ethyllphosphate (AIEP), and Aspartate provide important information for substrate binding and selectivity of OsGH3-8. Moreover, the observation that AIEP nearly occupies the entire binding site for AMP, IAA and amino acid, offers a ready explanation for the inhibitory effect of AIEP. Taken together, the present study provides vital insights into the molecular mechanisms of monocot GH3 function, and will help to shape the future designs of effective inhibitors.

Synthesis, characterization and photophysical properties of meso-indole-boron-dipyrromethene derivatives and their cell imaging and viscosity sensing

Based on the molecular design and structural modification of boron-dipyrromethene (BODIPY), two new BODIPY derivatives with meso-substituted functional indole moieties were successfully prepared. These new compounds were characterized by NMR, HAMS and FTIR, exhibiting the different UV-vis and PL spectral phenomena because of their varied molecular structures in various solvents and different degrees of negative solvatochromism. Theoretical calculations and CV results show that the substituted NO2 group at 5-position of indole is favorable for increasing the oxidation potential of the molecules, while the NH2 group is the opposite. These two BODIPY derivatives have different sensitivities to pH changes, and can be appropriately applied as cell imaging materials due to their good physical chemical characteristics and excellent biocompatibility. In particular, the fluorescence characteristics of BODIPY derivative with the substituted NH2 group at 5-position of indole show a good solvent viscosity dependence, highlighting its potential application for testing the intracellular viscosity changes of the living cell in disease diagnosis.

Synthetic Route of 80-71-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 80-71-7 is helpful to your research.

Facile synthesis of isatins by direct oxidation of indoles and 3-iodoindoles using NIS/IBX

A facile one-pot access to a broad range of isatins by direct oxidation of indoles using NIS/IBX reagent in DMSO at 25 degrees C in very good isolated yields is reported. It is shown by mechanistic investigations that a number of substituted indoles react rapidly with NIS in DMSO to produce intermediary 3-iodoindoles, which undergo oxidation subsequently to isatins with IBX.

Alkanethiol-Mediated Cyclization of o-Alkynylisocyanobenzenes: Synthesis of Bis-Thiolated Indole Derivatives

Reactions of o-alkynylisocyanobenzenes with a variety of alkanethiols (Alk-SH) provide the corresponding bis-thiolated indole derivatives. The advantages of the reaction include metal-free, room-temperature, mild reaction conditions and broad functional group compatibility. The reaction proceeds via nucleophilic addition of an alkanethiol to an isonitrile moiety, 5-exo cyclization, followed by nucleophilic addition of an alkanethiol to a 3-alkylidene indole intermediate. Density functional calculations on the electronic structures and relative free energies of 5-exo and 6-endo cyclization pathways support that the 5-exo cyclization is preferable.

EFFECTS OF ZINC ON INDOLE CARBOXYLIC ACID AND INDOLE ACETIC ACIDS CONTENTS IN RADISH SHOOT

Radish (Raphanus sativus L.) was grown for several experiments in a glasshouse with and without zinc (Zn) in the nutrient solution. Lack of zinc resulted in stunted growth and reduced leaf of radish shoots. Two-dimensional thin layer chromatography (TLC) and gas chromatography-mass spectrometry (GC-MS) analysis revealed the presence of indole carboxylic acid (ICA) (ester + free) and IAA (ester + free) in Zn-deficient radish shoots. Alkali-labile (1M NaOH) ICA and IAA in Zn deficient radish shoots were estimated with the use of GC. The content of ICA in Zn deficient radish shoots was higher than that of control radish shoots. These results suggest that ICA (ester + free) was accumulated in Zn-deficient radish shoots. But the content of IAA (ester + free) in Zn-deficient radish shoots was almost the same as that of control radish shoots. These results suggest that zinc nutrition did not affect the level of IAA in radish shoots.
