Selective Quadruple C(sp(3))-F Functionalization of Polyfluoroalkyl Ketones

The significance of organofluorine compounds has inspired the establishment of numerousmethods for the functionalization of rather inert C-F bonds. Despite advances achieved in the manipulation of C(sp(2))-F bonds by employing transitionmetal catalysts, such as Pd, Rh, Cu, Ni, Ru, and Ir, strategies that address the paucity of effective pathways for selective activation of multiple C(sp(3))-F bonds remained challenging. In this context, we present an unprecedented coupling-aromatization-cyclization reaction of polyfluorinated ketones with diverse Nand S-nucleophiles that forms regiodefined perfluoroalkylated naphtho[1,2-b] furan/benzofuran derivatives by harnessing Co-promoted distinctive quadruple C(sp(3))-F bonds cleavage relay. This chemistry involving controlled and successive selective defluorination at heteronuclear centers would greatly contribute to the preparation of drug-like heterocycles as well as the late-stage elaboration of bio-relevant compounds. Controlled experiments and DFT theoretical studies revealed that the combination of cheap cobalt salt with Cs2CO3 enable expeditious C-F functionalization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 97148-39-5. Product Details of 97148-39-5.

A Green Mechanochemical One-Pot Three-Component Domino Reaction Synthesis of Polysubstituted Azoloazines Containing Benzofuran Moiety: Cytotoxic Activity Against HePG2 Cell Lines

A one-pot procedure for the synthesis of azolopyrimidine derivatives by a three-component reaction of beta-ketosulfone, aldehyde, and 2-aminoben-zimidazole over synthetic magadiite clay (SMC-H) under ball milling in the absence of any solvent and additive has been developed. The catalyst was re-used for consequent reactions. The novel manufactured compounds were verified for HePG2 cell development inhibition. A pronounced inhibitory effect on the growth of HePG2 cell line was recorded. This protocol offers a broad scope for an access to a variety of diversely substituted azolopyrimidines of high inhibition activity against HePG2 cell line. The use of non-hazardous organic solvent, ball milling, cost efficiency, recyclability of the catalyst up to six runs without appreciable loss of activity, and high yields of products make this procedure greener.

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.

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.

Orally Administered Benzofuran Derivative Disaggregated A beta Plaques and Oligomers in the Brain of 5XFAD Alzheimer Transgenic Mouse

Amyloid-beta (A beta) aggregated forms are highly associated with the onset of Alzheimer’s disease (AD). A beta abnormally accumulates in the brain and induces neuronal damages and symptoms of AD such as cognitive impairment and memory loss. Since an antibody drug, aducanumab, reduces A beta aggregates and delays clinical decline, clearance of accumulated A beta in the brain is accounted as a therapeutic approach to treat AD. In this study, we synthesized 17 benzofuran derivatives that may disaggregate A beta oligomers and plaques into inert monomers. By a series of A beta aggregation inhibition and aggregates’ disaggregation assays utilizing thioflavin T assays and gel electrophoresis, YB-9, 2-((5-methoxy-3-(4-methoxyphenyl)benzofuran-6-yl)oxy)acetic acid, was selected as the final A beta-disaggregator candidate. When it was orally administered to the 8-month-old male transgenic mouse model with five familial AD mutations (5XFAD) via drinking water daily for two months, A beta oligomers and plaques in hippocampus were reduced. Consequently, decreased astrogliosis and rescued synaptic dysfunction were observed in the hippocampus of YB-9-treated 5XFAD mice compared with the untreated transgenic control group.

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.

Intercepted Retro-Nazarov Reaction: Syntheses of Amidino-Rocaglate Derivatives and Their Biological Evaluation as eIF4A Inhibitors

Rocaglates are a family of natural products isolated from the genus Aglaia which possess a highly substituted cyclopenta[b]benzofuran skeleton and inhibit cap-dependent protein synthesis. Rocaglates are attractive compounds due to their potential for inhibiting tumor cell maintenance in vivo by specifically targeting eukaryotic initiation factor 4A (eIF4A) and interfering with recruitment of ribosomes to mRNA. In this paper, we describe an intercepted retro-Nazarov reaction utilizing intramolecular tosyl migration to generate a reactive oxyallyl cation on the rocaglate skeleton. Trapping of the oxyallyl cation with a diverse range of nucleophiles has been used to generate over 50 novel amidino-rocaglate (ADR) and amino-rocaglate derivatives. Subsequently, these derivatives were evaluated for their ability to inhibit cap-dependent protein synthesis where they were found to outperform previous lead compounds including the rocaglate hydroxamate CR-1-31-B.

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.
