Study on pine sawdust pyrolysis behavior by fast pyrolysis under inert and reductive atmospheres

Fast pyrolysis of pine sawdust (PS) was investigated in a drop tube quartz reactor to understand the effects of temperature and atmosphere (Ar and H2) on the product yields, gas composition, bio-oil characteristics (organic composition and molecular mass distributions (MMDs)), and the carbon and oxygen conversion. The pyrolysis behavior and typical products from PS pyrolysis were also conducted using a thermogravimetry-mass spectroscopy (TG-MS) and pyrolysis-gas-chromatography/mass spectrometry (Py-GC/MS). The results show that the highest oil yields can be obtained at 500?C of 55.09 and 54.41?wt.% under Ar and H2 atmosphere, respectively. In comparison to an inert atmosphere, H2 created lower oil yields but higher gas yields, especially for CO and CH4 yields, and narrower MMDs, smaller Mn and Mw, and fewer char especially at high temperatures. The high temperatures and H2 atmosphere contribute to the oxygen and carbon transferring from material to volatile, especially to the gaseous products. H2 can promote the secondary cracking of macromolecules and weaken the re-polymerization of anhydrosugar and lignin oligomers.

Synthesis and antibacterial activity of novel chalcone derivatives of apocynin

A series of novel chalcones 1a- 1l (12 compounds) has been synthesized by using commercially available apocynin and aromatic aldehydes. The newly synthesized chalcone derivatives were screened for their antibacterial activities against gram positive and gram negative bacteria at the concentrations 10 of mug/mL with reference to the standard antibacterial drug Gentamycin. The screening results revealed that among the tested analogs, compounds having the hetero rings such as benzo[b]furan, furan and pyridine (1j,1k and 1l) in the structure exhibited excellent antibacterial activity while the compounds bearing fluorine, 2-CF3, 4-CF3 and 4-OCF3 (1f, 1g, 1h and 1i) also exhibited good to excellent activity. 2013 Bentham Science Publishers.

One-pot cascade synthesis of 2,3-disubstituted 2,3-dihydrobenzofurans via ortho-quinone methide intermediates generated in situ

A simple and efficient one-pot cascade reaction for the regioselective synthesis of trans or cis/trans 2,3-disubstituted 2,3-dihydrobenzofurans is reported. The method involves fluoride-induced desilylation, generation of o-quinone methide (o-QM) by chloride or nitrate anion elimination, Michael addition and intramolecular 5-exo-tet elimination of a bromide anion. Nitrate, acetoxy and chloride anions are compared as leaving groups in the formation of the in situ generated o-QM.

Discovery of (2S,3R)-N-[2-(pyridin-3-ylmethyl)-1-azabicyclo[2.2.2]oct-3-yl] benzo[b]furan-2-carboxamide (TC-5619), a selective alpha7 nicotinic acetylcholine receptor agonist, for the treatment of cognitive disorders

(2S,3R)-N-[2-(Pyridin-3-ylmethyl)-1-azabicyclo[2.2.2]oct-3-yl]benzo[b] furan-2-carboxamide (7a, TC-5619), a novel selective agonist of the alpha7 neuronal nicotinic acetylcholine receptor, has been identified as a promising drug candidate for the treatment of cognitive impairment associated with neurological disorders. 7a demonstrated more than a thousand-fold separation between the affinities for the alpha7 and alpha4beta2 receptor subtypes and had no detectable effects on muscle or ganglionic nicotinic receptor subtypes, indicating a marked selectivity for the central nervous system over the peripheral nervous system. Results obtained from homology modeling and docking explain the observed selectivity. 7a had positive effects across cognitive, positive, and negative symptoms of schizophrenia in animal models and was additive or synergistic with the antipsychotic clozapine. Compound 7a, as an augmentation therapy to the standard treatment with antipsychotics, demonstrated encouraging results on measures of negative symptoms and cognitive dysfunction in schizophrenia and was well tolerated in a phase II clinical proof of concept trial in patients with schizophrenia.

Novel tacrine?benzofuran hybrids as potential multi-target drug candidates for the treatment of Alzheimer?s Disease

Pursuing the widespread interest on multi-target drugs to combat Alzheimer?s disease (AD), a new series of hybrids was designed and developed based on the repositioning of the well-known acetylcholinesterase (AChE) inhibitor, tacrine (TAC), by its coupling to benzofuran (BF) derivatives. The BF framework aims to endow the conjugate molecules with ability for inhibition of AChE (bimodal way) and of amyloid-beta peptide aggregation, besides providing metal (Fe, Cu) chelating ability and concomitant extra anti-oxidant activity, for the hybrids with hydroxyl substitution. The new TAC-BF conjugates showed very good activity for AChE inhibition (sub-micromolar range) and good capacity for the inhibition of self- and Cu-mediated Abeta aggregation, with dependence on the linker size and substituent groups of each main moiety. Neuroprotective effects were also found for the compounds through viability assays of neuroblastoma cells, after Abeta1-42 induced toxicity. Structure-activity relationship analysis provides insights on the best structural parameters, to take in consideration for future studies in view of potential applications in AD therapy.

A nontoxic reversible thermochromic binary system: Via pi-pi Stacking of sulfonephthaleins

The mechanisms of thermochromic materials are mostly based on Bragg reflection, surface plasmon absorption, molecular structure changes, conformational stretching or aggregation. Here, a simple class of dye-solvent binary systems with clear and reversible thermochromism around ambient temperatures is reported with an alternative mechanism. This system comprises commercially available sulfonephthaleins dissolved in liquid linear chain esters, acids or alcohols, which demonstrate colour changes at different temperatures when the solvents transition from solid to liquid states. The colour changing mechanism is based on pi-pi stacked aggregation or disaggregation of the sulfonephthalein dyes. Cell toxicity tests confirmed that the sulfonephthalein dyes are less toxic to NIH-3T3 cells than cyanidin chloride, which is the only reported nontoxic food dye affording thermochromism, while this is based on an alternative mechanism. With the choice of a nontoxic solvent, this binary system can form a nontoxic thermochromic material.

Vacuum co-pyrolysis of Chinese fir sawdust and waste printed circuit boards. Part I: Influence of mass ratio of reactants

Vacuum co-pyrolysis of Chinese fir sawdust (CFS) and waste printed circuit boards (WPCBs) at different mass ratios were examined in this paper. The structures and contents of the pyrolysis oils were analyzed by Fourier transform infrared (FTIR) spectroscopy and gas chromatography?mass spectrometry (GC?MS). The results showed that co-pyrolysis processes presented antagonistic effect in the yield of the total volatiles (liquid plus gas) at the experimental conditions, but it is beneficial to the formation of brominated aromatic compounds (whose total content in WPCBs pyrolysis oil was only 6.51?wt%, while in co-pyrolysis processes (CFS/WPCBs?=?4:1, 1:1, 1:4), they were 10.96?wt%, 7.98?wt% and 14.84?wt%, respectively). The co-pyrolysis processes were also analyzed by thermogravimetric (TG) analysis with evolved product analysis by FTIR. The results showed that the volatiles were mainly formed between 300 and 450?C, and after 450?C, there were mainly some noncondensable gases (CO2, CO and CH4) formed.
