Bioactive Compounds Produced by the Accompanying Microflora in Bulgarian Yoghurt

Bulgarian yoghurt is associated with health benefits and longevity of consumers. The specific microflora producing bioactive metabolites is responsible for this effect. The present study examines the biodiversity in four homemade yoghurts from regions containing endemic microflora. Metagenome sequencing indicated Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus were predominant in all samples. In addition, yoghurts contained accompanying lactic acid bacteria (LAB) including Lacticaseibacillus paracasei, Lb. helveticus, Limosilactobacillus fermentum, Lb. rhamnosus, Lactococcus lactis, Pediococcus acidilactici, Leuconostoc mesenteroides, and Leuc. pseudomesenteroides. A negligible amount of pollutant strains was found. Twenty-four LAB strains were isolated from the yoghurts and identified. Lb. delbrueckii subsp. bulgaricus strains were genotyped by randomly amplified polymorphic DNA-PCR (RAPD), multi-locus sequence typing (MLST), and pulse field gel electrophoresis (PFGE), which demonstrated their uniqueness and non-commercial origin. To estimate the bioactive metabolites produced by the accompanying microflora, yoghurts fermented by single LAB strains were analyzed using liquid chromatography and mass spectrometry (LC-MS). The fermented samples contained large amounts of free essential amino acids (arginine, citrulline, tryptophan, lysine, and histidine), the neuroprotector indole-3-propionic acid (IPA), and significant quantities of the cyclic antimicrobial peptides cyclo(phenylalanyl-prolyl) and cyclo(leucyloprolyl). The disclosure of these special qualities draws attention to the accompanying microflora as a source of potential probiotic strains that can fortify the yoghurts’ content with bioactive compounds.

Geissospermiculatine, a New Alkaloid from Geissospermum reticulatum Bark

A new alkaloid, geissospermiculatine was characterized in Geissospermum reticulatum A. H. Gentry bark (Apocynaceae). Here, following a simplified isolation protocol, the structure of the alkaloid was elucidated through GC-MS, LC-MS/MS, 1D, and 2D NMR (COSY, ROESY, HSQC, HMBC, H-1-N-15 HMBC). Cytotoxic properties were evaluated in vitro on malignant THP-1 cells, and the results demonstrated that the cytotoxicity of the alkaloid (30 mu g/mL) was comparable with staurosporine (10 mu M). Additionally, the toxicity was tested on zebrafish (Danio rerio) embryos in vivo by monitoring their development (0-72 h); toxicity was not evident at 30 mu g/mL.

Chemoselective Cu-catalyzed synthesis of diverse N-arylindole carboxamides, beta-oxo amides and N-arylindole-3-carbonitriles using diaryliodonium salts

Chemoselective copper-catalyzed synthesis of diverse N-arylindole-3-carboxamides, beta-oxo amides and N-arylindole-3-carbonitriles from readily accessible indole-3-carbonitriles, alpha-cyano ketones and diaryliodonium salts has been developed. Diverse N-arylindole-3-carboxamides and beta-oxo amides were successfully achieved in high yields under copper-catalyzed neutral reaction conditions, and the addition of an organic base (DIPEA) resulted in a completely different selectivity pattern to produce N-arylindole-3-carbonitriles. Moreover, the importance of the developed methodology was realized by the synthesis of indoloquinolones and N-((1H-indol-3-yl)methyl)aniline and by a single-step gram-scale synthesis of the naturally occurring cephalandole A analogue.

Discovery and pharmacological evaluation of indole derivatives as potent and selective ROR gamma t inverse agonist for multiple autoimmune conditions

Targeting nuclear receptor ROR gamma is recognized to be beneficial in multiple autoimmune disorders. We disclosed new indole analogues as potent ROR gamma inverse agonists. RO-2 as one of the potent and orally bioavailable compounds was evaluated in various models of autoimmune disorder. It showed potent suppression of downstream markers of ROR gamma t activity in murine and human primary cells, ex vivo PD assay and in multiple animal models of autoimmune diseases. The results indicate the potential of these indole analogues as orally bioavailable small molecule inverse agonists of ROR gamma t, efficacious in various Th17 driven models of autoimmune disorders.

Indole Degradation in a Model System and in Poultry Manure by Acinetobacter spp.

Indole degradation in a model system and in poultry manure was studied using an enrichment culture of two Acinetobacter species; Acinetobacter toweneri NTA1-2A and Acinetobacter guillouiae TAT1-6A. Degradation of indole was quantified using reverse phase high performance liquid chromatography (HPLC). The two strains were capable of degrading initial concentrations of indole ranging from 58.58-300 mg/L. The degradation efficiency was 66.36% (NTA1-2A), 94.87% (TAT1-6A), and 96.00% (mix) in 6 days when the initial concentration <300 mg/L. The strains were tested for enzymatic activity using 120 mg/L indole. The enzyme extracts of NTA1-2A and TAT1-6A from culture medium degraded indole completely, and no appreciable change of indole concentration was witnessed in the control group. The NTA1-2A, TAT1-6A, and the mix of strains were also used for in vivo poultry manure fermentation and removed 78.67%, 83.28%, and 83.70% of indole, respectively in 8 d. The strains showed a statistically significant difference (p < 0.05) in indole removal efficiency compared with the control, but no significant difference between the two strains and the mix in indole removal capacity. We concluded that A. toweneri NTA1-2A and A. guillouiae TAT1-6A are promising strains to remove indole and its derivatives to control the notorious odor in poultry and other livestock industries. Synthetic Route of 1003-04-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1003-04-9.

Complete Genomes of the Anaerobic Degradation Specialists Aromatoleum petrolei ToN1(T) and Aromatoleum bremense PbN1(T)

The betaproteobacterial genus Aromatoleum comprises facultative denitrifiers specialized in the anaerobic degradation of recalcitrant organic compounds (aromatic and terpenoid). This study reports on the complete and manually annotated genomes of Ar. petrolei ToN1(T) (5.41 Mbp) and Ar. bremense PbN1(T) (4.38 Mbp), which cover the phylogenetic breadth of the genus Aromatoleum together with previously genome sequenced Ar. aromaticum EbN1(T) [Rabus et al., Arch Microbiol. 2005 Jan;183(1):27-36]. The gene clusters for the anaerobic degradation of aromatic and terpenoid (strain ToN1(T) only) compounds are scattered across the genomes of strains ToN1(T) and PbN1(T). The richness in mobile genetic elements is shared with other Aromatoleum spp., substantiating that horizontal gene transfer should have been a major driver in shaping the genomes of this genus. The composite catabolic network of strains ToN1(T) and PbN1(T) comprises 88 proteins, the coding genes of which occupy 86.1 and 76.4 kbp (1.59 and 1.75%) of the respective genome. The strain-specific gene clusters for anaerobic degradation of ethyl-/propylbenzene (strain PbN1(T)) and toluene/monoterpenes (strain ToN1(T)) share high similarity with their counterparts in Ar. aromaticum strains EbN1(T) and pCyN1, respectively. Glucose is degraded via the ED-pathway in strain ToN1(T), while gluconeogenesis proceeds via the reverse EMP-pathway in strains ToN1(T), PbN1(T), and EbN1(T). The diazotrophic, endophytic lifestyle of closest related genus Azoarcus is known to be associated with nitrogenase and type-6 secretion system (T6SS). By contrast, strains ToN1(T), PbN1(T), and EbN1(T) lack nif genes for nitrogenase (including cofactor synthesis and enzyme maturation). Moreover, strains PbN1(T) and EbN1(T) do not possess tss genes for T6SS, while strain ToN1(T) does and facultative endophytic Aromatoleum sp. CIB is known to even have both. These findings underpin the functional heterogeneity among Aromatoleum members, correlating with the high plasticity of their genomes.

A Route to Indoles via Modified Fischer Indole Intermediates from Sulfonanilides and Ketene Dithioacetal Monoxides

An S-N variant of the N-N-based Fischer indole synthesis has been developed. Treatment of sulfonanilides and ketene dithioacetal monoxides with a powerful acid anhydride providesN-sulfonyl-2-methylsulfanylindoles. The initial interrupted Pummerer reaction would yield the key S-N-tethered precursor in situ that then undergoes [3,3] sigmatropic rearrangement, after which the endgame to the indole ring follows the Fischer manner.
