Totally colorless, transparent, and highly refractive poly(phenylene thioether ether)s (PPTEs) containing thianthrene-2,7-disulfanyl moiety were developed in this study. A new 4,4′-diol aromatic compound, 2,7-(4,4′-diphenol)thiothianthrene (DPTT), with a high sulfur content was designed and synthesized to develop polymers with high refractive indices and high thermal stabilities. The PPTEs were prepared by polycondensation of DPTT with organic dihalogen compounds, such as 2,6-difluorobenzonitrile (DFBN) and 4,6-dichloro-2-(methylthio) pyrimidine (DCMP). The obtained polymers showed good thermal stabilities such as relatively high glass transition temperatures (T(g)s) in the range of 153-176 degrees C and 5% weight loss temperatures (T-5%) over 344 degrees C. The cut-off wavelengths (lambda(0)) of the PPTE films are shorter than 343 nm, and they have a transmittance higher than 93% at 550 nm. The combination of the pyrimidine and high sulfur-containing thianthrene derivatives provides the PPTEs with a high refractive index of 1.7204 and a small birefringence of 0.0106 at 637 nm.

The direct C-H arylation and acylation of azoles with carboxylic acids were achieved through Pd/Cu cooperative catalysis. Various biaryls and biaryl ketones were selectively produced in good to high yields from the same substrates. The key factor of high chemoselectivity was the choice of a suitable phosphine ligand: biaryls were generated selectively with dppp as the ligand, while biaryl ketones were obtained with high selectivity using dpph or Ph2PCy as the ligand.

This report details a decarboxylative cross-coupling of (hetero)aryl carboxylates with iodoarenes in the presence of a gold catalyst (>25 examples, up to 96% yield). This reaction is site specific, which overcomes prior limitations associated with gold catalyzed oxidative coupling reactions. The reactivity of the (hetero)aryl carboxylate correlates qualitatively to the field effect parameter (F-ortho). Reactions with isolated gold complexes and DFT calculations support a mechanism proceeding through oxidative addition at a gold(I) cation with decarboxylation being viable at either a gold(I) or a silver(I) species.

Present work demonstrates synthesis and antibacterial property of new pyrazole derivatives. A series of new Curcumin based dihydropyrazoles has been synthesized with an objective to evaluate their antibacterial property. Dihydropyrazoles analogues were synthesized using Curcumin based chalcones and differently substituted phenylhydrazine derivatives. We used the previously designed Curcumin based chalconesto react with phenylhydrazine derivatives in ethanol in a catalyst free medium to afford new dihydropyrazole derivatives. Effect of substituent on reactivity was also studied. All the synthesized pyrazole analogues were characterized using proton and carbon NMR, Mass spectroscopy and IR techniques. Effect of substituent on reactivity was explained on the basis of electronic effect generated due to groups on phenyl ring. Presence of dd (double doublet) in proton NMR spectrum of Dihydropyrazoles was also explained due to presence of optically active carbon of pyrazole ring. The synthesized library was screened for their inhibitory activity against 4 different bacterial strains 1. E. Coli (ATCC 9637), 2. Pseudomonas aeruginosa (ATCC BAA-427), 3. Staphylococcus aureus (ATCC 25923) and 4. Klebsiella pneumonia (ATCC 27736). Out of all the compounds evaluated, the compounds that exhibited IC50 value greater than 50 mu M, were considered to be inactive. We established an important SAR based on the structure dependent inhibitory potential of screened dihydropyrazoles. Two compounds 4e and 4t having nitro and benzyl substitution respectively were showing the best inhibitory potential against Gram Positive bacterial strain Staphylococcus aureus with MIC value of 1.56 mu g/ml. Compounds having Chloro and Methoxy substitution were found to be less effective against screened bacterial strains. Compounds 4a and 4b were selective towards Staphylococcus aureus species with the MIC value of 1.56 mu g/ml for each. These pyrazole analogues were not showing inhibitory potential against other screened bacterial strains.

Understanding the nature of interactions between the aromatic organic pollutants with dissolved humic acid (HA) is fundamental for the prediction of their environmental fate and subsequent development of efficient remediation methods. The present study employs solution-state H-1/F-19 NMR methods to investigate the non-covalent interaction between aqueous peat humic acid (Aldrich HA) and monoaromatic carboxylic acids (CA), viz., 2, 6 diflourobenzoic acid (DFBA) and its non-fluorinated analog, benzoic acid (BA). NMR self-diffusion measurement of HA protons confirmed micellar nature indicating possibility of encapsulation of small molecules through host-guest interaction. F-19-H-1 and H-1-H-1 saturation transfer difference (STD) experiments reveal the mode of insertion of CA into HA superstructure. The strength of interaction has been evaluated by analyzing T-1/T-2 relaxation times and self-diffusion coefficients of CA as a function of HA concentration. Association constants extracted for CA-HA complexes from NMR diffusion experiments reflected that the association between DFBA-HA (2.34 mM(-1)) is significantly higher than that of BA-HA (0.97 mM(-1)). The experimental outcome reiterated that substitution of -H with halogen atoms (-F in specific) to aromatic ring plays a dominant role in modulating the strength of association and mode of insertion of organic pollutants into HA superstructure. The present study emphasizes that AHA can be a potential remediating agent for organic contaminants due to its superior binding affinity compared to less humified extracted HA (EHA) from Karwar, Rajasthan, India.

I found the field of Oncology very interesting. Saw the article European cancer mortality predictions for the year 2020 with a focus on prostate cancer published in 2020. HPLC of Formula: C8H10O2, Reprint Addresses La Vecchia, C (corresponding author), Univ Milan, Dept Clin Sci & Community Hlth, Via Vanzetti 5, Milan 20122, Italy.. The CAS is 151-10-0. Through research, I have a further understanding and discovery of 1,3-Dimethoxybenzene

Background: Current cancer mortality figures are important for disease management and resource allocation. We estimated mortality counts and rates for 2020 in the European Union (EU) and for its six most populous countries. Materials and methods: We obtained cancer death certification and population data from the World Health Organization and Eurostat databases for 1970-2015. We estimated projections to 2020 for 10 major cancer sites plus all neoplasms and calculated the number of avoided deaths over 1989-2020. Results: Total cancer mortality rates in the EU are predicted to decline reaching 130.1/100 000 men (similar to 5.4% since 2015) and 82.2 in women (similar to 4.1%) in 2020. The predicted number of deaths will increase by 4.7% reaching 1 428 800 in 2020. In women, the upward lung cancer trend is predicted to continue with a rate in 2020 of 15.1/100 000 (higher than that for breast cancer, 13.5) while in men we predicted further falls. Pancreatic cancer rates are also increasing in women (+1.2%) but decreasing in men (similar to 1.9%). In the EU, the prostate cancer predicted rate is 10.0/100 000, declining by 7.1% since 2015; decreases for this neoplasm are similar to 8% at age 45-64, 14% at 65-74 and 75-84, and 6% at 85 and over. Poland is the only country with an increasing prostate cancer trend (+18%). Mortality rates for other cancers are predicted to decline further. Over 1989-2020, we estimated over 5 million avoided total cancer deaths and over 400 000 for prostate cancer. Conclusion: Cancer mortality predictions for 2020 in the EU are favourable with a greater decline in men. The number of deaths continue to rise due to population ageing. Due to the persistent amount of predicted lung (and other tobacco-related) cancer deaths, tobacco control remains a public health priority, especially for women. Favourable trends for prostate cancer are largely attributable to continuing therapeutic improvements along with early diagnosis.

A new series of Pyrazolo[3,4-d]pyrimidine containing amide derivatives (8 a-l) were designed, synthesized, and evaluated for their in vitro alpha-amylase inhibitory activity. The IC50 values of the target compounds ranged from 1.60 +/- 0.48 to 2.04 +/- 1.20 mu M as compared to the standard acarbose 1.73 +/- 0.05 mu M. All the Pyrazolo[3,4-d]pyrimidine amide derivatives displayed good inhibitory activities, while seven analogs (8 d, 8 f, 8 g, 8 h, 8 i, 8 j and 8 k) exhibited more or less equipotent activity with IC50 values 1.77 +/- 2.84, 1.65 +/- 0.45, 1.66 +/- 2.24, 1.73 +/- 0.37, 1.60 +/- 0.48, 1.75 +/- 0.36 and 1.64 +/- 0.03 mu M respectively. Further, the most potent alpha-amylase inhibitors 8 d and 8 k were also screened for their in vivo antidiabetic activity against alloxan induced diabetic rat model at the dose of 25 and 50 mg/kg. Oral administration of these tested compounds significantly reduced the fasting blood glucose levels in dose dependent manner. The hypoglycemic effects of these compounds were more evident at 3 h and 5 h after administration of tested compounds which was similar to the effect displayed by the positive control. In addition, the binding energies calculated from the docking studies with the alpha-amylase enzyme (PDB ID: 1HNY) and biological activities indicate that the compounds containing nitro moiety on the phenyl group contributed significantly towards the antidiabetic activity.

(+)-Nootkatone, a non-food bioactive natural bicyclic sesquiterpene ketone, is isolated from Chamaecyparis nootkatensis [D. Don] Spach as a renewable forest resource. In continuation of our effort to develop synthetic natural derived insecticides from non-food bioactive products, a small library of thirty N-(1,3- thiazol-2-yl) carboxamides fused (+)-nootkatone was prepared by molecular hybridization and characterized by H-1/C-13 NMR, HR-MS, and IR spectroscopy. Their insecticidal activities against Mythimna separata Walker and Plutella xylostella Linnaeus were evaluated. Compounds B6, B7, B9, B19-21 and B24 showed better insecticidal activity against M. separata than the botanical insecticide azadirachtin, and their LC50 values ranged from 0.55 -0.68 mg/mL. Particularly, compound B9 exhibited 1.87-fold more pronounced insecticidal activity against M. separata than azadirachtin. The insecticidal activity of B21 against P. xylostella was 1.37-fold of that of azadirachtin. Through acetylcholinesterase (AChE) inhibitory activity and molecular docking studies, AChE may be the insecticidal target of B9 against M. separata. In addition, three pronounced compounds B9, B21 and B24 exhibited low hemolytic and cytotoxic activities on normal mammalian cells. These findings will give insights into the further development of (+)-nootkatone derivatives as potentially synthetic natural derived insecticides for pest management.

A new series of novel chromene-based oxadiazole derivatives were synthesized from a variety of chromene-based amidoximes with readily available carboxylic acids under conventional oil bath heating as well as under microwave irradiation. The use of commercially available EDCI and HOBt as coupling reagents in DMF combined with microwave heating resulted in high yields and purities of the product 1,2,4-oxadiazoles in an expeditious manner. This methodology is successfully applied to synthesize 18 numbers of new 2H-chromene-substituted 1,2,4-oxadiazole derivatives in good to high yields. The structure of the product was ascertained by X-ray crystallographic analysis. All the synthesized compounds were evaluated for their in vitro antibacterial activity against two different pathogenic bacterial strains, that is, Escherichia coli (MTCC614) and Klebsiella pneumoniae (MTCC4031). The obtained results from in vitro antimicrobial assays indicated that 6g and 6h exhibited good antibacterial activity nearer to the standard drug, gentamicin. The molecular docking studies showed that compounds 6g and 6h show hydrogen bonding interaction with the bacterial target DNA gyrase of E. coli.
