New lead discovery of insect growth regulators based on the scaffold hopping strategy

Insect growth regulators (IGRs), which can interrupt or inhibit pest life cycles, are low-toxicity pesticides widely used in integrated pest management (IPM). Ecdysone analogues and chitinase inhibitors are familiar IGRs that have attracted considerable attention because of their unique modes of action and low toxicity to non-target organisms. To find new and highly effective candidate IGRs with novel mechanisms, D-08 (N-(4-(tert-butyl) phenyl)-2-phenyl-2,4,5,6,7,8-hexahydrocyclohepta[c]pyrazole-5-carboxamide) was chosen as a lead compound, and a series of novel heptacyclic pyrazolamide derivatives were designed and synthesized using the scaffold hopping strategy. The bioassay showed that 111-27 (N-(2-methylphenethyl)-1-phenyl-1,4,5,6,7,8-hexahydrocyclohepta[c]pyrazole-5-carboxamide) had excellent activity against Plutella xylostella. Protein verification and molecular docking indicated that III-27 could act on both the ecdysone receptor (EcR) and Ostrinia furnacalis chitinase (Of ChtI) and is a promising new lead IGRs. The interaction mechanism of 111-27 with EcR and Of ChtI was then studied by molecular docking. These results provide important guidance for the study of new dual-target IGRs.

Recent advancements in the development of heterocyclic anti-inflammatory agents

Most of the anti-inflammatory drugs in clinical practice are becoming outdated owing to their potential side and adverse effects. These are found to be highly unsafe for long term use. Thus, since last few years, new anti-inflammatory agents are being developed and number of them are in advanced stages of clinical trials. Heterocyclic molecules have gained great attention of chemists due to their similarity to different biological precursors. In the current review, we have highlighted the recent developments (2015 onwards) in designing and synthesis of various heterocyclic anti-inflammatory molecules along with detailed SAR studies. The principal objective of this review is to provide a profound overview of the recently explored heterocyclic anti-inflammatory agents belonging to various classes such as pyrazole, pyrimidine, benzimidazole, indole, and other related heterocyclic compounds. In addition, an enlarged view on potential interactions of synthetic preparations with target inflammatory enzymes or cytokines has been provided. We have also enlisted lead compounds undergoing different clinical trials against inflammation. The elementary aim of this review is to provide restructured knowledge regarding heterocyclic molecules which will be valuable for the scientists working in the field of anti-inflammatory chemistry. The authors believe that lead compounds mentioned in the report will help to design and develop novel anti-inflammatory drug molecules targeting various factors involved in the progression of inflammation.

Synergistic Effect of Pendant N Moieties for Proton Shuttling in the Dehydrogenation of Formic Acid Catalyzed by Biomimetic Ir(III)Complexes

Formic acid (FA) is among the most promising hydrogen storage materials. The development of efficient catalysts for the dehydrogenation of FA via molecular-level control and precise tuning remains challenging. A series of biomimetic Ir complexes was developed for the efficient dehydrogenation of FA in an aqueous solution without base addition. A high turnover frequency of 46510 h(-1)was achieved at 90 degrees C in 1 mFA solution with complex1bearing pendant pyridine. Experimental and mechanistic studies revealed that the integrated pendant pyridine and pyrazole moieties of complex1could act as proton relay and facilitate proton shuttling in the outer coordination sphere. This study provides a new strategy to control proton transfer accurately and a new principle for the design of efficient catalysts for FA dehydrogenation.

In order to develop potent anticaner agents, a novel series of 3-(1H-indol-3-yl)-2,3,3a,4-tetrahydrothiochromeno[4,3-c]pyrazole derivatives were synthesized. Structures of all compounds were confirmed. MTT assay has been employed to study antiproliferative activity of these compounds with four human cancer cell lines (MGC-803, Hela, MCF-7 and Bel-7404) and a normal cell line L929. Most of these compounds showed potential anticancer activity and low cytotoxicity on normal cell in vitro. 7d and 7f showed the best anticancer activity, whose IC50 value is 15.43 mu M and 20.54 mu M towards MGC-803, respectively. Most of them exhibited topoisomerase II selective inhibitory. Cleavage reaction assay and DNA unwinding assay showed that 7f was a nonintercalative Topo II catalytic inhibitor, which was consistent with the docking results. Laser scanning confocal microscopy system tracks the location of representative compounds 7d and 7f which can be abundantly entering the nucleus. In particular, the most potent compounds 7d and 7f were shown to be able to induce G2/M cell cycle arrest and apoptosis in MGC-803 cells. (C) 2020 Elsevier Masson SAS. All rights reserved.

Experimental and DFT studies on Hexacoordinated acyl(alkyl)and Pentacooordinated Hydroxyalkyl(phosphinite)erhodium(III). Catalytic Hydrolysis of Ammonia Borane

[Rh(nbd)Cl](2) (nbd=norbornadiene) reacts with quinoline-8-carbaldehyde (C9H6NCHO) and pyrazole (Hpz) affording, depending on Rh/Hpz ratio, acyl-alkyl [Rh(mu-Cl)(C9H6NCO)(Hpz)(sigma-C7H9)](2) (1) or [RhCl(C9H6NCO)(Hpz)(2)(sigma-norbornenyl)] (2), stereoselectively as confirmed by DFT calculations. Hydrogen bond between NH-pyrazole and O-acyl occurs. 1 and 2 react with diphenylphosphine oxide (SPO) giving 16e [RhCl(C9H6NC(nbyl))(Ph2PO)(Hpz)] (3) through SPO kappa(1)-P-coordination, C-C bond coupling between acyl and norbornenyl and outer-sphere O(P)-to-O(C) hydrogen transfer. 3 shows distorted trigonal bipyramidal structure with weak intramolecular (C)-OH…O(=P) and NH…Cl hydrogen bonds. DFT calculations indicate this 16e structure being favoured by sigma- and pi-type orbital multi-overlapping between pyrazole and both the OH…O and chlorine and by intermolecular forces in the crystal. Solutions of 3 contain an equilibrium between trigonal bipyramid and a square-planar pyramid with OH interacting with phosphoryl and NH, confirmed by DFT C-13 NMR calculations. 1 is very efficient homogeneous catalyst for H3N-BH3 hydrolysis to release hydrogen under air.

Enhanced Optoelectronic and Biological Potential of Virescent-Glowing Terbium(III) Complexes with Pyrazole Acid

A series of five virescent color emitting terbium(III) complexes is fabricated by a cost-effective and eco-friendly solution precipitation technique with the utilization of 1-(4-methoxyphenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (L) as a primary ligand and highly conjugated nitrogen donor secondary ligands such as bathophenanthroline (batho), 5,6-dimethyl-1,10-phenanthroline (dmph), 1,10-phenanthroline (phen) and 2,2-bipyridyl (bipy). The elemental compositions of complexes are examined through energy dispersive x-ray and elemental analyses, whilst the binding nature of ligand with terbium(III) ion is confirmed using proton nuclear magnetic resonance and infrared spectroscopy. The band gap energy (E-g) of complexes is found in the range of 3.85-3.34 eV as evaluated from diffuse reflectance spectral data. The significant thermal stability of these luminescent materials (157 degrees C) demonstrates their key role as virescent component in white organic light emitting diodes. The intense emission and decay time of complexes are explored through photoluminescent study. The good color purity and Commission International De I’Eclairage color coordinates promise the enhanced performance of these materials in lighting appliances. The sensitization phenomenon highlights the role of ligands in increasing the luminescence intensity of complexes. The biological assessment indicates that the complexes are potent antimicrobial and antioxidant agents. The aforementioned features extend the field of applications of complexes in laser technology and optoelectronic devices.
