Synthesis of calix[4]crowns containing soft donor atoms and a study of their metal-cation binding properties: Highly selective receptors for Cu2+

Two new calix[4]arenethiacrown derivatives 1 and 2 in the cone conformation were synthesized by two different pathways in good yield. Their complexation properties toward alkali, alkaline earth and transition metal cations were studied in acetonitrile at 298.15 K using a conductometric titration technique. The selectivity for Cu2+ over other cations with these novel ligands was excellent.

Design, synthesis, and structure-activity relationship studies of thiophene-3-carboxamide derivatives as dual inhibitors of the c-Jun N-terminal kinase

We report comprehensive structure-activity relationship studies on a novel series of c-Jun N-terminal kinase (JNK) inhibitors. Intriguingly, the compounds have a dual inhibitory activity by functioning as both ATP and JIP mimetics, possibly by binding to both the ATP binding site and to the docking site of the kinase. Several of such novel compounds display potent JNK inhibitory profiles both in vitro and in cell.

Catalytic Redox Chain Ring Opening of Lactones with Quinones to Synthesize Quinone-Containing Carboxylic Acids

Catalytic ring opening of five- to eight-membered lactones with quinones is achieved through a redox chain mechanism. With low loading of a simple metal triflate Lewis acid catalyst and a chain initiator, C-H bonds of many quinones were efficiently functionalized with carboxylic acid-containing side chains. This method also features 100% atom economy and wide substrate scope. A novel route to the anti-asthma drug Seratrodast was developed. Mechanism study suggests that the redox chain reaction likely undergoes a carbocation intermediate.

Evaluation and prediction of slow pyrolysis products derived from coals of different rank

When coal is heated slowly (<10 C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable gases. Knowledge of the temperature profile together with the coal decomposition behaviour is of great importance when designing a fixed bed gasification plant, and although the characterisation of tar and the composition thereof has been reported extensively, there is limited literature available on the prediction of tar composition formed during slow pyrolysis. The focus of this study was to investigate temperature and coal rank effects on pyrolysis product yield, and to predict (using FLASHCHAIN) the char, tar, water and gas yields when heated at slow heating rates for coals of different rank (ranging from lignite B to bituminous C). A modified Fischer Assay setup was used to investigate pyrolysis at temperatures higher than that of the ISO 647 standard, i.e. 520, 720 and 920 C and the tar quality was determined via SEC?UV (size exclusion chromatography?ultraviolet), GC?MS (gas chromatography?mass spectrometry), SimDis (simulated distillation) and ultimate analysis. Only the char yield was found to be rank dependent and the average molecular weight of the coal derived tars (212?415 Da) compared well with previous studies. The rank dependence based on the composition of the evolved volatiles (tar and gas), showed a linear relationship with elemental oxygen and carbon contents of the derived tar, as well as for the oxygen containing gases (CO and CO2). FLASHCHAIN was able to provide a relatively accurate prediction of the char yield, poorer predictions of the tar and water yields and no correlation with the gas yield. The simulated results on tar composition showed poor promise. Statistical regression was also applied in order to determine correlations between coal properties and the pyrolysis product yields and composition. It was found that the mineral elements (Na2O, MgO, CaO, TiO2 and Fe2O3) have strong correlations with tar yield, thus implying that catalytic effects of the mineral matter appear to play a significant role in the formation and decomposition of coal derived tar, which is a limitation in all pyrolysis predictive models.

Optimization of carbofuran insecticide degradation by Enterobacter sp. using response surface methodology (RSM)

Response surface methodology and Plackett-Burman experiments were applied to optimize the biodegradation of carbofuran by using Enterobacter sp. stain BRC05 isolated from selected agricultural areas in peninsular Malaysia. The significant factors influencing the degradation of carbofuran were assessed using two-level Plackett?Burman Design (PBD) with five variables. Plakett Burman experiment showed that the following four variables were significant for carbofuran degradation including, carbofuran concentration, temperature, pH and nitrogen sources. Significant variables obtained in Plackett-Burman Design were further optimize using Central Composite Design (CCD). The outcome of the design for carbofuran degradation for each runs of the PBD experiment base on the design matrix, showed that the minimum and the maximum carbofuran degradation percentage were found to be 6.7% and 79.77% as presented in runs 4 and 1, respectively. Results obtained using Central Composite Design showed that the relations between the factors affect carbofuran degradation with significant response. The predicted results in CCD indicated that highest carbofuran degradation of 95.40% could be realized with carbofuran concentration of 92.50 mg/L, pH of 6.0, temperature 27.50 C, nitrogen sources of 0.45 g/L and reaction period of 6 days. The predicted values were in agreement with the actual values with coefficient of determination with R2 0.9719. Partial 16S rRNA sequence analysis showed that the carbofuran degrading isolate was closely related to members of the genera Enterobacter sp. The morphological and biochemical characteristics of the isolate also confirmed the phylogenetic signature. This study would provide an effective approach that could be beneficial for the bioremediation of carbofuran insecticide in polluted environment.
