Crystalline and Stable Benzofuran-Linked Covalent Organic Frameworks from Irreversible Cascade Reactions

We report the synthesis of crystalline two-dimensional covalent organic frameworks (COFs) by connecting hydroxybenzene-aldehyde and acetonitrile building blocks to form cyano-substituted benzofuran linkages. Unlike the majority of COFs that were synthesized based on condensation reactions, the COFs in this report are crystallized from irreversible cascade reactions involving consecutive cyanide migration, ring-closure, and oxidation reactions. The irreversible property endows the COFs with high chemical stability in both acid and base and allows them to be postsynthetically modified to install predesigned functionality under harsh conditions. We highlight that the functionalized COFs serve as exceptional vehicles for superprotonic conductions.

In vitro toxicokinetics and analytical toxicology of three novel NBOMe derivatives: phase I and II metabolism, plasma protein binding, and detectability in standard urine screening approaches studied by means of hyphenated mass spectrometry

Purpose Toxicokinetic studies are essential in clinical and forensic toxicology to understand drug-drug interactions, influence of individual polymorphisms, and elimination routes, as well as to evaluate targets for toxicological screening procedures. N-(2-Methoxybenzyl)-substituted phenethylamines (NBOMe analogues) intake has been associated with severe adverse reactions including deaths. 1-(1-Benzofuran-5-yl)-N-[(2-methoxyphenyl)methyl]propan-2-amine (5-APB-NBOMe), 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(5-chloro-2-ethoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NB2EtO5Cl), and 2-(8-bromo-2,3,6,7-tetrahydrobenzo[1,2-b:4,5-b ‘]difuran-4-yl)-N-[(2-methoxyphenyl)methyl]ethan-1-amine (2C-B-FLY-NBOMe) are three emerging NBOMe analogues, which have encountered on the drugs of abuse market. So far, their toxicokinetic data are completely unexplored. Methods The study included mass spectrometry-based identification of phase I and II metabolites following exposure to the terminally differentiated human hepatocellular carcinoma cells (HepaRG). The determination of enzymes involved in the major phase I/II metabolic steps and determination of plasma protein binding (PPB) were done. Finally, the evaluation of the toxicological detectability by different hyphenated mass spectrometry techniques in standard urine screening approaches (SUSAs) was investigated. Results The compounds were extensively metabolized in HepaRG cells mainly via O-dealkylation, hydroxylation, glucuronidation, and combinations thereof. CYP1A2, 2D6, 2C8, 2C19, and 3A4, were involved in the initial reactions of all investigated compounds. Glucuronidation of the phase I metabolites-when observed-was mainly catalyzed by UGT1A9. The PPB of all compounds was determined to be > 85%. Only the high-resolution mass spectrometry-based SUSA allowed detection of all compounds in rat urine, but only via metabolites. Conclusions The toxicokinetic data provided by this study will help forensic and clinical toxicologists to reliably identify these substances in case of abuse and/or intoxication and will allow them a thorough risk assessment.

Investigation of anti-inflammatory and toxicity effects of mangrove-derived Streptomyces rochei strain VITGAP173

Mangrove ecosystems generate the major biodiversity hotspots of actinobacteria. Among the actinobacteria, Streptomyces species are the prolific producers of bioactive natural products. In this study, with research efforts to discover biopotential compounds from marine actinobacteria, 41 actinobacterial strains were isolated from sediment soil sample of Indian mangrove regions. The phylogeny prediction using the 16S rRNA gene sequences revealed that the isolates were related to Streptomyces. Isolates were further screened based on a two-step process wherein the first step, around nine strains, unveiled the presence of type 1 polyketide synthase gene and dTDP-glucose 4,6-dehydratase gene through polymerase chain reaction. As the second step of the screening process, cell viability assay was performed in RAW264.7 cells to assess the toxicity of extracts. Among all the isolates, Streptomyces rochei strain VITGAP173 was subjected to further analysis. To explore the bioactivities, the organic solvent extraction method was utilized to extract the broth culture of VITGAP173. Inhibition of nitric oxide and cyclooxygenase enzymes upon lipopolysaccharide-induced inflammation were utilized to evaluate the anti-inflammatory efficacy, and the results showed the potency of VITGAP173 in a dose-dependent manner. The extract significantly suppressed the messenger RNA levels of the inflammatory mediators such as tumor necrosis factor-alpha and interleukin-6 induced by lipopolysaccharide in RAW264.7 macrophages. The presence of several chemical constituents was identified through gas chromatography-mass spectrometry analysis of VITGAP173 extract. To achieve the toxicity analysis, oral administration of VITGAP173 extract in Wistar albino rats was carried out to investigate the biochemical parameters, histopathology which revealed its nontoxic nature.

Synthesis and Evaluation of Some Novel Essential Amino Acid-Benzofuran-Acetamide/Propanamide/Butanamide Hybrids as Potential Anticonvulsant Agents

In this study, some new essential amino acid-benzofuran-acetamide/propanamide/butanamide hybrid derivatives were synthesized. The structures of the synthesized compounds were confirmed on the basis of their elemental and spectral analyses. Their anti-seizure activity was investigated using maximal electroshock seizure (MES) and subcutaneous metrazol (scMET) seizure tests in mice. Neurotoxicity (NT) of the synthesized compounds was also determined by the rotarod test. Derivatives exhibited favorable protection in both MES and scMET tests with high safety levels in NT test. The derivatives have proven significant activity in mice and could be suggested as potential anticonvulsant lead compounds. All leucine-chlorobenzoyl benzofuran-acetamide/propanamide/butanamide hybrid derivatives (6b, 7b, and 8b) showed significant anticonvulsant activity in MES model. Compound 8b also demonstrated potent anticonvulsant activity against scMET test. The compound 8b showed maximum activity and would be considered as a lead for further optimization as anticonvulsant agent. [GRAPHICS]

SYNTHETIC APPROACH FOR BUILDING HETEROANNULATED FURO[3,2-g]CHROMENES USING 4,9-DIMETHOXY-5-OXO-5H-FURO[3,2-g]CHROMENE-6-CARBONITRILE AND CYCLIC CARBON NUCLEOPHILE

A novel series of polyfused heterocyclic systems containing furo[3,2-g]chromenes were efficiently synthesized. The reactivity of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) was studied towards a variety of carbon nucleophilic reagents such as heterocyclic enols, heterocyclic enamines and cyclic active methylene compounds. Treatment of carbonitrile 1 with 4-hydroxycoumarin, 4-hydroxy-1-methylquinolin-2(1H)-one (3), 2-hydroxy-4H-pyrido[1,2-a]pyrimidin-4-one (4) afforded furodichromenopyridine 2, furochromenonaphthyridine 5, furochromenodipyridopyrimidine 6. Reaction of carbonitrile 1 with 4(6)-aminouracil and 5-amino-3-methyl-1H-pyrazole proceed through ring opening followed by cycloaddition into the nitrile group giving pyrido[2,3-d]pyrimidine 7 and pyrazolo[3,4-b]pyridine 8. Also, reaction of carbonitrile 1 with 5-amino-2,4-dihydro-3H-pyrazol-3-one (9), 2-(phenylimino)-1,3-thiazolidin-4-one (11), thiobarbituric acid and cyclohexane-1,3-dione produced the novel annulated furo[3,2-g]chromenes 10, 12-14, respectively. Cyclohexane-1,2-dione reacted with carbonitrile 1 in 1:2 molar ratio afforded bis-(furochromeno)[1,10]phenanthroline 15. The prepared compounds were screened in vitro for their antimicrobial activity and some of them appeared notable activity against the tested microorganisms.

From Alkynes to Heterocycles through Metal-Promoted Silylformylation and Silylcarbocyclization Reactions

Oxygen and nitrogen heterocyclic systems are present in a large number of natural and synthetic compounds. In particular, oxa- and aza-silacyclane, tetrahydrofuran, benzofuran, cycloheptadifuranone, cycloheptadipyrrolone, pyrrolidine, lactone, lactam, phthalan, isochromanone, tetrahydroisoquinolinone, benzoindolizidinone, indoline and indolizidine scaffolds are present in many classes of biologically active molecules. Most of these contain a C=O moiety which can be easily introduced using carbonylative reaction conditions. In this field, intramolecular silylformylation and silylcarbocyclization reactions may afford heterocyclic compounds containing a carbonyl functional group together with a vinylsilane moiety which can be further transformed. Considering these two aspects, in this review a detailed analysis of the literature data regarding the application of silylformylation and silylcarbocyclization reactions to the synthesis of several heterocyclic derivatives is reported.

Secondary Metabolites of the Siberian Strains Heterobasidion annosum sensu lato

The composition of secondary metabolites from strains Heterobasidion genus isolated in central and western Siberia and in South Korea were studied. Morphological-cultural and molecular-genetic methods were used to assign the cultures to the species of H. annosum (Fr.) Bref. (five strains), H. abietinum Niemela & Korhonen (four strains), and H. ecrustosum Tokuda, T. Hatt. & Y.C. Give (one strain). Fomannoxin predominated in the metabolome profiles of three H. annosum strains and all H. abietinum strains. Two strains of H. annosum synthesized fomannoxin-related compounds: 2-(2-hydroxypropan-2-yl)-2,3-dihydrobenzofuran-5-carbaldehyde and 2-(2-hydroxypropan-2-yl)benzofuran-5-carbaldehyde. Fomannosin and its precursors were identified in H. annosum 45-2. It was shown that the composition of the fermentation medium affected the number and range of the synthesized metabolites. Under in vitro conditions, all H. annosum and H. abietinum strains exhibited phytopathogenic effects on Pinus sylvestris L. seedlings, causing necrotic damage to stems of various degrees and plant death. Higher phytopathogenicity is characteristic of H. annosum strains: maximal aggressiveness was observed in H. annosum 45-2 with the greatest diversity of compounds in the metabolome profile and active fomannoxin production.
