BACKGROUND: Chemical pesticides are the main measures for pest control, but have caused growing resistance of pests and brought a series of environmental problems. Development of high-efficient insecticidal molecules with novel scaffolds is therefore particularly urgent. RESULTS: Based on a [5 + 1] annulation reaction with 5-amino-1H-phenylpyrazole and dialkyl bromomalonate, 27 novel five-substituted 4,5-dihydropyrazolo[1,5-a]quinazolines were designed following the intermediate derivatization method and synthesized. Bioassay results indicated that most of the test compounds displayed good insecticidal activities against Plutella xylostella, Spodoptera frugiperda, and Solenopsis invicta. In particular, the insecticidal activities of compounds 4a, 4f, and 4m against P. xylostella [median lethal concentration (LC50) values ranged from 3.87 to 5.10 mg L-1] were comparable to that of indoxacarb (LC50 = 4.82 mg L-1). In addition, compounds 4a and 9e showed similar high insecticidal activities against Spodoptera frugiperda (mortality rate = 79.63% and 72.12%) at 100 mg L-1, comparable to that of fipronil (mortality rate: 68.44%); compound 9a showed possible delayed toxicity against Solenopsis invicta (mortality rate: 95.66%) after 5 days of treatment at 1.0 mg L-1. CONCLUSION: Due to their high insecticidal activities against P. xylostella, compound 4m, 4a, and 4f could be considered as qualified candidates for novel insecticide. Several other 4,5-dihydropyrazolo[1,5-a]quinazolines with relatively high bioactivity, such as compounds 9a and 9e, are also worth further optimization as potential insecticide or anticide candidates.

The methoxy-, hydroxy-, and carbonyl-substituted benzenes are the simplest fragments from the lignin separation feedstocks. Extensive experimental thermochemical studies of these compounds were carried out, including combustion calorimetry, vapor pressure measurements, and differential scanning calorimetry. We have collected available primary experimental results on enthalpies of formation and vapor pressures as well as on phase transitions, liquid-gas, liquid-solid, and crystal-liquid. These data were evaluated using empirical, semiempirical, and quantum chemical methods. The consistent sets of evaluated thermodynamic data were used to design the method for predicting enthalpies of vaporization and enthalpies of formation of di- and trisubstituted benzenes. It is expected that parameters and pairwise interactions will be transferable to predict the thermochemical properties of poly methoxy-substituted and poly hydroxysubstituted benzenes that appear in reaction products of lignin transformations in the value-adding chemicals and materials.

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.

Green synthesis of pyrazolo[3,4-b]quinolinones was designed using bioproduct pyridine-2-carboxylic acid (P2CA) as a green and efficient catalyst. The multi-component reaction of aldehydes, 1,3-cyclodiones and 5-amino-1-phenyl-pyrazoles regioselectively produced pyrazolo[3,4-b]quinolinones in excellent yield (84-98%). Recyclization of the catalyst was also investigated. The electronic effect of the various substituents in aromatic rings indicated that the reaction proceeded through the carbocation intermediate. This newly designed protocol very quickly constructed products conventionally under milder conditions.

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.

This work reports the synthesis of a novel quinolin-4(3H)-one based Schiff base ligand 3-[(E)-(2,5-dimethox-yphenyl)methylidene]amino-2-methylquinazolin-4(3H)-one (DMPAQ) and its coordination complexes of the type [M(DMPAQ)(phen)]X (1a-1c), where M = Cu(II), Zn(II) and Cd(II) ions, respectively, phen = 1,10-phe-nanthroline. All the synthesized compounds were characterized using UV-Visible, elemental analysis, FT-IR, H-1 NMR, Mass spectroscopy and TGA techniques. The triclinic structure of the DMPAQ is determined by employing single crystal X-ray crystallographic analysis. The characterization results suggested that the ligand, DMPAQ is bidentate and coordinate to the metal center through the lactum oxygen and the azomethine nitrogen. The synthesized DMPAQ ligand and complexes (1a-1c) were screened for their in vitro anticancer activity against the human breast adenocarcinoma cell line, MCF-7. The complexes 1a and 1b displayed significant anticancer ac-tivity against MCF-7 cells even at lower GI50 value (GI(50) = 0.016 mu M) than the standard drug doxorubicin (GI(50) = 0.018 mu M). Further, we have performed computational DFT studies on the chemical reactivity of the ligand and the three complexes by means of Conceptual Density Functional Theory (CDFT) through the Koopmans in DFT (KID) approximation to support the experimentally obtained results.
