ZSM-5 zeolite is an efficient catalyst for both biomass deoxygenation and polyolefins cracking in pyrolysis process. In this study, wood-plastic composite (WPC), composed mainly of woody materials and thermoplastic polymers, was pyrolyzed using Py-GC/MS over phosphorus-modified HZSM-5 (P-HZSM-5) with varying P loadings (from 0 to 10 wt.%). The catalysts were prepared by wet impregnation method and characterized by XRF, XRD and NH3-TPD. The effects of pyrolysis temperature, time, heating rate, catalyst to WPC ratio and P loadings on the hydrocarbon distribution of WPC pyrolysis were studied. Pyrolysis conditions have significant effects on hydrocarbon distribution. Parent HZSM-5 facilitated aromatics formation, while P-HZSM-5 favored the formation of light aliphatic hydrocarbons (C4-C12). The yields of C4-C12 increased first with rising pyrolysis temperature from 450 to 550 C, then decreased over 550 C. Similarly, C4-C12 yields increased during the pyrolysis time from 15 to 30 s and decreased with the further prolonged time. A low heating rate (0.002 C/ms) favored the formation of light aliphatic hydrocarbons, while high heating rates (>0.2 C/ms) favored the formation of aromatics. Increasing catalyst to WPC ratio augmented aromatic selectivity. Hydrocarbon distribution strongly depended on the catalyst’s acidity, adjusted by varying P loading in P-HZSM-5. The highest yield of C4-C12 was obtained while using P-HZSM-5 with P loading of 3.5 wt.%.

With the aim of developing novel scaffolds as anticancer agents and inhibitors of NF-kappaB activity, 60 novel benzofuran- and 2,3-dihydrobenzofuran-2-carboxylic acid N-(substituted)phenylamide derivatives (1a-s, 2a-k, 3a-s, and 4a-k) were designed and synthesized from the reference lead compound KL-1156, which is an inhibitor of NF-kappaB translocation to the nucleus in LPS-stimulated RAW 264.7 macrophage cells. The novel benzofuran- and 2,3-dihydrobenzofuran-2-carboxamide derivatives exhibited potent cytotoxic activities (measured by the sulforhodamine B assay) at low micromolar concentrations against six human cancer cell lines: ACHN (renal), HCT15 (colon), MM231 (breast), NUGC-3 (gastric), NCI-H23 (lung), and PC-3 (prostate). In addition, these compounds also inhibited LPS-induced NF-kappaB transcriptional activity. The +M effect and hydrophobic groups on the N-phenyl ring potentiated the anticancer activity and NF-kappaB inhibitory activity, respectively. However, according to the results of structure-activity relationship studies, only benzofuran-2-carboxylic acid N-(4?-hydroxy)phenylamide (3m) was the lead scaffold with both an outstanding anticancer activity and NF-kappaB inhibitory activity. This novel lead scaffold may be helpful for investigation of new anticancer agents that act through inactivation of NF-kappaB.

Complete removal of tar from wastewater is one of the most challenging problems in the pyrolysis of low?rank coal. In this study, the properties and composition of tar are comprehensively analyzed, and the reasons for the difficulty of oil?water separation are expounded. A separation method using tar fraction as extractant is also developed. Results show that the oil content in the wastewater can be reduced to less than 300 mg·L?1 when the boiling point of the fraction is 120?140 C and the volume ratio of the extractant to the wastewater system is 1:4 at room temperature without adjusting the pH value of the wastewater. This condition can meet the requirements of follow-up treatment devices and reduce the biological toxicity of wastewater. The revamping scheme and important operation parameters of the distillation unit are optimized through simulation. The proposed method is simple, has low investment cost, and does not require buying chemicals. The method exhibits good industrial feasibility and is expected to solve the problem of oil?water separation in coal pyrolysis.

The potential of liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QqTOF-MS) to identify and confirm carbosulfan and seven of its main metabolites (carbofuran, 3-hydroxycarbofuran, 3-ketocarbofuran, 3-hydroxy-7-phenol carbofuran, 3-keto-7-phenolcarbofuran, 7-phenolcarbofuran, dibutylamine) at trace levels from food is explored for the first time. The analytical method developed consists of pressurized liquid extraction (PLE) and LC-QqTOF-MS in positive ion mode, which attains unequivocal identification and quantification of the studied compounds in food, at levels well below of those of concern (0.05 mg/kg for the sum of carbosulfan, carbofuran, and 3-hydroxycarbofuran). PLE recoveries ranged from 55 to 94% with limits of quantification from 10 (for carbosulfan, carbofuran, 3-hydroxycarbofuran, and dibutylamine) to 70 mug/kg (3-keto-7-phenolcarbofuran). The method is precise, with relative standard deviations varying between 5 and 11% for the repeatability (within-day) and 8-13% for the reproducibility (interday). This method was used to monitor the presence and fate of the target compounds in orange, potato, and rice crops treated with a commercial product containing carbosulfan. Field degradation studies show that carbofuran, 3-hydroxycarbofuran, and dibutylamine are the main degradation products formed in the environmental disappearance of carbosulfan.

BRD4, characterized by two acetyl-lysine binding bromodomains and an extra-terminal (ET) domain, is a key chromatin organizer that directs gene activation in chromatin through transcription factor recruitment, enhancer assembly, and pause release of the RNA polymerase II complex for transcription elongation. BRD4 has been recently validated as a new epigenetic drug target for cancer and inflammation. Our current knowledge of the functional differences of the two bromodomains of BRD4, however, is limited and is hindered by the lack of selective inhibitors. Here, we report our structure-guided development of diazobenzene-based small-molecule inhibitors for the BRD4 bromodomains that have over 90% sequence identity at the acetyl-lysine binding site. Our lead compound, MS436, through a set of water-mediated interactions, exhibits low nanomolar affinity (estimated Ki of 30-50 nM), with preference for the first bromodomain over the second. We demonstrated that MS436 effectively inhibits BRD4 activity in NF-kappaB-directed production of nitric oxide and proinflammatory cytokine interleukin-6 in murine macrophages. MS436 represents a new class of bromodomain inhibitors and will facilitate further investigation of the biological functions of the two bromodomains of BRD4 in gene expression.

Carbon monoxide (CO) and styrene derivatives that can be both generated by a palladium on carbon (Pd/C)-catalyzed carbon?carbon (C?C) bond cleavage reaction of cinnamaldehyde derivatives were effectively utilized in further palladium-catalyzed C?C bond forming reactions in a direct and practical way. CO derived from simple and affordable CO carriers such as cinnamaldehyde or terephthalaldehyde was efficiently employed in the in situ CO fixation with various aromatic iodides through a palladium-catalyzed carbonylation followed by an inter- or intramolecular coupling reaction with alcohols to afford the corresponding esters or lactones, respectively. Styrene derivatives were also efficient substrates in an in situ Mizoroki?Heck-type cross-coupling reaction with aryl iodides, leading to the effective formation of asymmetric stilbenes. The decarbonylation of cinnamaldehyde derivatives and the subsequent independent syntheses of both esters/lactones and 1,2-diarylethenes could be achieved in a virtual one-pot and in situ reaction using a H-shaped pressure-tight glass-sealed tube consisting of two independent but laterally connected reaction tubes in the gas space.

The aromathecin topoisomerase I (top1) inhibitors offer promising scaffolds for the development of novel cancer chemotherapeutics. They are ‘composites’ of the camptothecin and indenoisoquinoline top1 inhibitors. Interestingly, some structure-activity relationship (SAR) overlap between the aromathecins and the indenoisoquinolines has been observed. For both classes, placement of certain polar groups in similar regions of the heteroaromatic system improves top1 inhibitory and antiproliferative activities. A series of water-soluble aromathecins substituted at position 14 with diaminoalkanes of various lengths has been prepared. These compounds all possess similar antiproliferative potency, but a general trend is observed: aromathecins with longer diaminoalkane substituents (>6 carbons) possess lower anti-top1 activity than their smaller counterparts (2-4 carbons), presumably as a result of unfavorable hydrophobic interactions. This trend is also noted with the indenoisoquinolines, revealing additional SAR overlap that supports the hypothesis that there is a ‘universal’ top1 inhibitor SAR.
