Abstract:

Dietary fibre and polyphenols are both metabolised to short-chain fatty acids (SCFAs) and phenolic acids (PA) by the colonic microbiota. These may alter microbiota growth/diversity, but their interaction is not understood. Interactions between rutin and raftiline, ispaghula or pectin were investigated in human faecal batch cultures (healthy participants; 19–33 years, 4 males, 6 females, BMI 18.4–27.4) after a low (poly)phenol diet three days prior to study. Phenolic acids were measured by gas chromatography-mass spectrometry and SCFAs by gas chromatography-flame ionisation after 2, 4, 6, and 2

Regression analysis led to the conclusion that the antileukotrienic activities of compounds 2 correspond to the relationships between these activities and lipophilicity, derived for the previously synthesized series of substituted (arylsulfanyl)benzoic acids 1A, 1B and 1C. Acids 3 are outliers from these relationships, probably due to a somewhat different

Abstract:

The review deals with the role of aromatic amino acids and their microbial metabolites in the development and progression of non-alcoholic fatty liver disease (NAFLD). Pathological changes typical for NAFLD, as well as abnormal composition and/or functional activity of gut microbiota, results in abnormal aromatic amino acid metabolism. The authors discuss the potential of these amino acids and their bacterial metabolites to produce both negative and positive impact on the main steps of NAFLD pathophysiology, such as lipogenesis and inflammation, as well as on the liver functions through regula

ABSTRACT The yeast Trichosporon mucoides, grown on either glucose or phenol, was able to transform biphenyl into a variety of mono-, di-, and trihydroxylated derivatives hydroxylated on one or both aromatic rings. While some of these products accumulated in the supernatant as dead end products, the ortho-substituted dihydroxylated biphenyls were substrates for further oxidation and ring fission. These ring fission products were identified by high-performance liquid chromatography, gas chromatography-mass spectrometry, and nuclear magnetic resonance analyses as phenyl derivatives of hydroxymuco

We report a short synthetic route for synthesizing 2,3-substituted piperazine acetic acid esters. Optically pure amino acids were efficiently converted into 1,2-diamines that could be utilized to deliver the title 2,3-substituted piperazines in five steps with a high enantiomeric purity. The novel route facilitated, for the first time, the synthesis of 3-phenyl substituted-2-piperazine acetic acid esters that were difficult to achieve using other methods; however, in this case, the products underwent racemization.

Abstract:

The reactions of two 3-(2-allylanilino)-3-phenylacrylate esters with acetic anhydride and with strong acids has revealed a richly diverse reactivity providing a number of unexpected products. Thus, acetylation of ethyl 3-(2-allylanilino)-3-phenylacrylate, (Ia), or ethyl 3-(2-allyl-4-methylanilino)-3-phenylacrylate, (Ib), with acetic anhydride yields not only the expected acetylated esters, (II), as the major products but also the unexpected polysubstituted quinolines 3-acetyl-8-allyl-2-phenylquinolin-4-yl acetate, (IIIa), and 3-acetyl-8-allyl-6-methyl-2-phenylquinolin-4-yl acetate, (IIIb), as

Abstract:

Substitution reaction of 11-chloro-7-fluoro-2-isopropyl-10,11-dihydrodibenzo[b,f,]thiepin with 1-(2-hydroxyethyl)piperazine gave the title compound I which proved a very potent and longacting oral neuroleptic agent (isofloxythepin). Its resolution by means of dibenzoyl-(+)- and -(-)-tartaric acid led to (-)- and (+)-enantiomer out of which the former represents the neuroleptically active component. In the synthetic sequence leading to I, preparation of two key intermediates was re-elaborated using new partial sequences: 4-fluoro-2-iodobenzoic acid (XIII) from 4-fluoro-2-nitroaniline (V) via th

Abstract:

A new series of pyrrolyl benzamide derivatives (3a-3j) and Schiff base 4 were synthesized by reacting N-(2,5-dimethyl-1H-pyrrol-1-yl)-4-(2-hydrazenyl-2-oxoethoxy)benzamide (1) with substituted phenylacetic acids (2a-2j) and indole-3-carbaldehyde, respectively. Molecular docking was performed for these synthesized compounds against the InhA and dihydrofolate reductase (DHFR) mycobacterial enzymes. The compounds were biologically screened for antimycobacterial and antibacterial activities along with InhA and DHFR enzyme inhibition studies. The compounds were also analyzed for absorption, distrib

Abstract:

This paper describes the synthesis of new heterocycles from oxazol-5(4H)-one and 1,2,4-triazin-6(5H)-one classes containing a phenyl-/4-bromophenylsulfonylphenyl moiety. The oxazol-5(4H)-ones were obtained via condensation of 2-(4-(4-X-phenylsulfonyl)benzamido)acetic acids with benzaldehyde/4-fluorobenzaldehyde in acetic anhydride and in the presence of sodium acetate. The reaction of oxazolones with phenylhydrazine, in acetic acid and sodium acetate, yielded the corresponding 1,2,4-triazin-6(5H)-ones. The structures of the compounds were confirmed using spectral (FT-IR, 1H-NMR, 13C-NMR, MS) a

Tigernut processing generates nutritionally-rich residue, mostly discarded as waste. This research reports for the first time the amino acid profile, phenolic profile, and pasting properties of tigernut residues. Yellow and brown tigernut residues were analysed for amino acid and phenolic profile, antioxidant, techno-functional and pasting properties. The total essential amino acids were 49 and 56% for yellow and brown tigernut residue flours, respectively. The flavonoid content and ferric reducing antioxidant property were 0.91 and 0.32 mg GAE/ g, and 3.43 and 1.41 AAE/ g for yellow and brown

Abstract:

The growing interest in functional foods has fueled the hunt for novel lactic acid bacteria (LAB) found in natural sources such as fermented foods. Thus, the aims of this study were to isolate, identify, characterize, and quantify LAB’s antifungal activity and formulate an ingredient for meat product applications. The overlay method performed a logical initial screening by assessing isolated bacteria’s antifungal activity in vitro. Next, the antifungal activity of the fermented bacteria-free supernatants (BFS) was evaluated by agar diffusion assay against six toxigenic fungi. Subsequently, the

The condensation reaction between aminoguanidine bicarbonate with carboxylic acids led to the formation of 3-methyl-1H-1,2,4-triazole-5-amine (mta), 3-methyl-1H-1,2,4l4-triazole-5-amine acetate (Hmta) and 3-phenyl-1H-1,2,4-triazole-5-amine (pta). The compound N-(3-methyl-1H-1,2,4-triazole-5-yl)propan-2-imine (mpta) was obtained by reacting the mta with acetone, upon an attempt of purifying mta in this solvent. The excess of acetic acid obtained the Hmta during the preparation of mta. These compounds were characterised by infrared and multinuclear NMR (1H and 13C) spectroscopy, microanalysis, a

It has been reported that monoamine neurotransmitters can be produced by gut microbiota, and that several related metabolites of amino acids in these pathways are associated with nervous system (NVS) diseases. Herein, we focused on three pathways, namely, phenylalanine (Phe), tryptophan (Trp), and glutamic acid (Glu), and established an underivatized liquid chromatography–tandem mass spectrometry (LC-MS/MS) method for the quantification of nineteen monoamine neurotransmitters and related metabolites in the gut microbiota. The neurotransmitters and related metabolites included Phe, tyrosine (Ty
