Enhanced enzymatic removal of anthracene by the mangrove soil-derived fungus, Aspergillus sydowii BPOI

The present study investigated the efficiency of Aspergillus sydowii strain bpo1 (GenBank Accession Number: MK373021) in the removal of anthracene (100 mg/L). Optimal degradation efficiency (98.7%) was observed at neutral pH, temperature (30 degrees C), biomass weight (2 g) and salinity (0.2% w/v) within 72 h. The enzyme analyses revealed 131%, 107%, and 89% induction in laccase, lignin peroxidase, and manganese peroxidase respectively during anthracene degradation. Furthermore, the degradation efficiency (99.8%) and enzyme induction were significantly enhanced with the addition of 100 mg/L of citric acid and glucose to the culture. At varying anthracene concentrations (100-500 mg/L), the degradation rate constants (k(1)) peaked with increasing concentration of anthracene while the half-life (t(1/2)) decreases with increase in anthracene concentration. Goodness of fit (R-2 = 0.976 and 0.982) was observed when the experimental data were subjected to Langmuir and Temkin models respectively which affirmed the monolayer and heterogeneous nature exhibited by A. sydwoii cells during degradation. Four distinct metabolites; anthracene-1,8,9 (2H,8aH,9aH)-trione, 2,4a-dihydronaphthalene-1,5-dione, 1,3,3a,7a-tetrahydro-2-benzofuran-4,7-dione and 2-hydroxybenzoic acid was obtained through Gas Chromatography-Mass spectrometry (GC-MS). A. sydowii exhibited promising potentials in the removal of PAHs.

Catalytic asymmetric 1,4-type Friedel-Crafts (hetero)arylations of 1-azadienes: the highly enantioselective syntheses of chiral hetero-triarylmethanes

Direct enantioselective Michael-type Friedel-Crafts arylations and heteroarylations of s-cis 1-azadienes were achieved by applying chiral bifunctional tertiary amine-urea catalysts when using 2-naphthols as the nucleophiles, and phosphoric acid catalysts when using indoles as the nucleophiles. These two catalytic protocols efficiently enabled access to a diverse variety of important benzofuran-containing hetero-triarylmethanes in up to 98% yield and with 99.5 : 0.5 er.

Development of a Robust Protocol for the Synthesis of 6-Hydroxybenzofuran-3-carboxylic Acid

Benzofuran scaffolds are fundamental moieties found in a variety of biologically active natural products and synthetic drugs. In the course of one of our development programs, we needed to develop a practical and cost-effective manufacturing approach to such a benzofuran scaffold. Here we report a highly robust four-step, one-pot process that provides access to a 6-hydroxybenzofuran-3-carboxylic acid structure. An H-1 NMR monitoring study allowed a better understanding of the overall sequence of events and the nature of the detected intermediates. After six steps, including the optimized tandem process, the desired hydroxylated benzofuran was obtained in 40% yield with a purity above 99%.

Effects of different vegetable oils on the aroma characteristics of deep-fried shallot flavoring evaluated by HS-SPME/GC-MS coupled with PLSR

In this study, four fried shallot-flavored oil (FSO) samples prepared with different oil were analyzed by gas chromatography-mass spectrometry (GC-MS), descriptive sensory analysis (DSA), and electronic nose (E-nose). A total of 75 volatile compounds were identified, and 44, 34, 32, and 25 of these compounds were found in the FSOs with rapeseed oil, peanut oil, soybean oil and sunflower oils, respectively, which were conducted for comparison and evaluation of the aroma characteristics of FSOs. Seven sensory attributes (oily, pungent, cooked vegetable, grease, burnt, pickled, and shallot scent) were chosen to evaluate FSOs. DSA results showed a significant difference among these FSO samples for shallot scent and grease, and FSO2 heated by peanut oil presented strong in these two notes, but weaker in burnt, FSO3 also has the weaker burnt flavor. Moreover, E-nose analysis confirmed the results of GC-MS and DSA. Results of correlation analysis partial least squares regression (PLSR) among 50 volatile compounds and DSA data, indicated that 2-Ethyl-3,5-dimethyl-pyrazine, 2,3-Dihydro-benzofuran, and benzaldehyde contribute to grease flavor; 2-Ethyl-3,5-dimethyl-pyrazinemay contribute to shallot scent flavor, and further confirmed that peanut oil may be a suitable carrier oil for the sensory characteristics of FSO. Practical applications The unique shallot flavor and rich fat fragrance of FSO play an increasingly important role in the cooking and processing of dishes. However, there is relatively little research on FSO. In this study, FSO prepared by different types of oil can produce different flavor of FSO with dissimilar volatiles and sensory characteristics. We used PLSR to analyze the relationship between sensory attributes and compounds. These research contents will provide a basis for the industrialization of fried shallot oil.

Catalytic Carbonylative Double Cyclization of 2-(3-Hydroxy-1-yn-1-yl)phenols in Ionic Liquids Leading to Furobenzofuranone Derivatives

A catalytic carbonylative double cyclization method for the synthesis of furo[3,4-b]benzofuran-1(3H)-ones is reported. It is based on the reaction between readily available 2-(3-hydroxy-1-yn-1-yl)phenols, CO, and oxygen carried out in the presence of catalytic amounts of PdI2 (1 mol %) in conjunction with KI (20 mol %) and 2 equiv of diisopropylethylamine at 80 degrees C for 24 h under 30 atm of a 1:4 mixture of CO-air. Interestingly, the process was not selective when carried out in classical organic non-nucleophilic solvents (such as MeCN or DME), leading to a mixture of the benzofurofuranone derivative and the benzofuran ensuing from simple cycloisomerization, whereas it turned out chemoselective toward the formation of the double cyclization compound in BmimBF(4) as the reaction medium. Moreover, the ionic liquid solvent containing the catalyst could be easily recycled several times without appreciable loss of activity.

An investigation of the synthesis of vilazodone

A novel synthetic route toward vilazodone is described by using 4-cyanoaniline and 5-bromo-2-hydroxybenzaldehyde as starting materials, with an overall yield of 24% and 99% purity. First, the intermediate (3-(4-chlorobutyl)-1H-indole-5-carbonitrile) is synthesized via diazotization of 4-cyanoaniline, followed by Fischer indole cyclization with 6-chlorohexanal. Subsequently, another intermediate, 5-(piperazin-1-yl)benzofuran-2-carboxamide, is generated via aromatic nucleophilic substitution of 5-bromobenzofuran-2-carboxamide with piperazine. Finally, vilazodone is obtained via nucleophilic substitution of the above two key intermediates by treatment with Et3N/K2CO3. In comparison to the original process, this route avoids the use of expensive and toxic reagents and resolves issues such as safety, environmental concerns, and high costs.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 66357-35-5, you can contact me at any time and look forward to more communication. Computed Properties of C13H22N4O3S.

Synthesis of the Tetracyclic Cores of the Integrastatins, Epicoccolide A and Epicocconigrone A

The integrastatins, epicoccolide A and epicoccongirone A, are natural products containing a unique [6.6.6.6]-tetracyclic core framework that exhibit a broad spectrum of biological activities. A synthesis of the common core of epicoccolide A and epicocconigrone A has been achieved using an umpolung alkylation-lactonization to assemble an isochromanone from which the bridged 1,3-dioxane was readily assembled. A different strategy was required to access the core on the integrastatins; an initial aryllithium addition to an aldehyde, followed by oxidation and treatment of the masked dihydroxyketone with acid gave the desired core structure.

PIM kinase inhibitors: Structural and pharmacological perspectives

The PIM kinase, also known as serine/threonine kinase plays an important role in cancer biology and is found in three different isoforms namely PIM-1, PIM-2, and PIM-3. They are extensively distributed and are implicated in a variety of biological processes, including cell proliferation, cell differentiation, and apoptosis. They act as weak oncogene and whenever expressed in exacerbating forms are responsible for different types of human cancer. Recently, different isoforms of PIM kinase have been identified as a clinical biomarker and potential therapeutic target for personalized treatment of advanced cancer. The inhibition of PIM kinase has become a scientific interest and some inhibitors have been developed and/or are under different phases of clinical trials. Several medicinally privileged heterocyclic ring scaffolds such as pyrrole, pyrimidine, thiazolidine, benzofuran, indole, triazole, oxadiazole, and quinoline derivatives have been synthesized and evaluated for their PIM inhibitory activity. This review comprehensively focuses on pharmacological implications of PIM kinases in oncogenesis, structural insights of PIM inhibitors and their structure-activity relationships (SARs).

Novel potent (dihydro)benzofuranyl piperazines as human histamine receptor ligands – Functional characterization and modeling studies on H-3 and H(4 )receptors

Histamine acts through four different receptors (H1R-H4R), the H3R and H4R being the most explored in the last years as drug targets. The H3R is a potential target to treat narcolepsy, Parkinson’s disease, epilepsy, schizophrenia and several other CNS-related conditions, while H4R blockade leads to anti-inflammatory and immunomodulatory effects. Our group has been exploring the dihydrobenzofuranyl-piperazines (LINS01 series) as human H3R/H4R ligands as potential drug candidates. In the present study, a set of 12 compounds were synthesized from adequate (dihydro)benzofuran synthons through simple reactions with corresponding piperazines, giving moderate to high yields. Four compounds (1b, 1f, 1g and 1h) showed high hH(3)R affinity (pK(i) > 7), compound 1h being the most potent (pK(i) 8.4), and compound if showed the best efficiency (pKi 8.2, LE 0.53, LLE 5.85). BRET-based assays monitoring G alpha(i) activity indicated that the compounds are potent antagonists. Only one compound (2c, pK(i) 7.1) presented high affinity for hH(4)R. In contrast to what was observed for hH(3)R, it showed partial agonist activity. Docking experiments indicated that bulky substituents occupy a hydrophobic pocket in hH(3)R, while the N-allyl group forms favorable interactions with hydrophobic residues in the TM2, 3 and 7, increasing the selectivity towards hH(3)R. Additionally, the importance of the indole NH in the interaction with Glu5.46 from hH(4)R was confirmed by the modeling results, explaining the affinity and agonistic activity of compound 2c. The data reported in this work represent important findings for the rational design of future compounds for hH(3)R and hH(4)R.
