N-ferrocenylpyridazinones and new organic analogues: Synthesis, cyclic voltammetry, DFT analysis and in vitro antiproliferative activity associated with ROS-generation

Employing an optimized Pd-catalyzed cross-coupling reaction promoted by CuI, novel N-ferrocenylpyridazinones along with N-phenyl- and N-(2-pyridyl) analogues were synthesized from readily available heterocyclic precursors, iodoferrocene, iodobenzene and 2-bromopyridine. With exception of the ferrocenylation of 6-ferrocenylpyridazin-3(2H)-one yielding both N- and O-substituted products, the studied reactions exclusively afforded N-aryl lactams. The novel compounds exhibited cytotoxicity towards HEPG2 and HT-29 human malignant cells under in vitro conditions. The measured IC50 values supplemented with the results of cyclic voltammetry and DFT calculations suggest that the cytotoxic activity of the N- and O-ferrocenyl-substituted derivatives and the decreased effect of the N-phenyl analogues seem to be at least partly associated with the potential to generate reactive oxygen species (ROS). This interpretation, allowing the prediction of characteristic substituent-dependent SAR, was supported by the results of related studies on the practically inactive N-(2-pyridyl)pyridazinones assumed to be present in protonated chelate forms with highly a decreased propensity to undergo ionization.

Tri- and difluoromethoxylated N-based heterocycles – Synthesis and insecticidal activity of novel F3CO- and F2HCO-analogues of Imidacloprid and Thiacloprid

The preparation of F3CO- and F2HCO-analogues of Imidacloprid and Thiacloprid and the evaluation of their biological activity have been performed. For this purpose, a first synthetic approach allowed the preparation of a desired F3CO-containing key intermediate. To allow a facile access to the second F2HCO-containing key intermediate, the difluoromethylation of hydroxylated N-based heterocycles has been developed using difluoromethyl triflate (a liquid non-ODS reagent) under air in aqueous conditions and with very short reaction time. The broad diversity of compatible heterocycles includes a large series of substituted hydroxy-pyridines, but also -pyrazoles, -pyrazine, -pyridazine, and -quinolines. The couplings of both key intermediates with the required 4,5-dihydro-N-nitro-1H-imidazol-2-amine and [N(Z)-N-2-thazolidinylidene-cyanamide were successfully achieved using literature conditions. This work enables the preparation of valuable building blocks, which could lead to the discovery of new bioactive entities.

Synthesis of some pyridazine derivatives as antioxidants and antimicrobial agents

Purpose: To prepare some pyridazine derivatives as antioxidant and antimicrobial agents. Methods: The coupling of aryl diazonium salts with diethyl 2-cyano-3-methylglutaconate afforded pyridazine-5-carbonitrile derivatives (3a-e). The methyl function in the pyridazine derivatives (3a-e) reacted with cinnamonitriles to yield phthalazine derivatives (6a-h). Imino-pyridazine derivatives (9a-h) were obtained by reacting 2-aminoprop-1-ene-1,1,3-tricarbonitrile along with aryl diazonium salts (1a-h). Structure elucidation was done by spectral analysis. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) technique was employed to assess antioxidant effect, while evaluation of antimicrobial activity was carried out by serial dilution technique. Results: Compounds, 6f (IC50 = 12.68 mu g/mL; p < 0.05), 6a (IC50 = 14.23 mu g/mL; p < 0.05), and 3c (IC50 = 14.34 mu g/mL; p < 0.05) displayed good antioxidant activity compared to ascorbic acid (IC50 = 12.45 mu g/mL; p < 0.05). Based on the zone of inhibition, compound 6c (p < 0.05) displayed higher activity than ofloxacin (p < 0.05) against E. coli. Conclusion: The presence of an oxo group and carboxylate group plays an important role in the antioxidant activity of these compounds. Compounds 6a, 6f, and 3c can potentially serve as lead compounds for the development of promising antioxidants.

Photochromism of dihydroindolizines. Part XXII: Significant effect of region B substituents on tuning the photophysical properties of photochromic dihydroindolizines: Absorption, kinetic and computational studies

Novel photochromic dihydroindolizines (DHIs) bearing different alkyl and cyclic alkyl ester group (region B) were prepared via electrophilic addition of fluorene spirocyclopropenes substituted with different alkyl ester groups in region B of the DHI skeleton to N-heterocyclic pyridazine in dry ether solution. The maxima of absorption (Amax) of the colored betaines (formed after UV-irradiation) were detected by UV/ Vis absorption measurement. The studied betaines showed one visible region absorption maxima between 517 and 548 nm. The kinetics of the 1,5-electrocyclization process of the colored betaines to closed DHIs system was studied spectrophotometrically in dichloromethane solution. Interestingly, a significant decrease in the half-life time by a factor of 8 was observed when alkyl of the ester group changed from methyl to pentyl alkyl groups. The activation parameters indicated that the changes of Olio are counterbalanced by changes in AS compensation effect. The enthalpy and entropy of the activation energies for the thermal back-reaction were compared to investigate the generalization and the limitation of the molecular intention of the photochromic DHIs lengthways with the correlation between unwieldiness of the substituents (region B) and the rate constant of the thermal back-reaction. DFI’ calculations are performed to explain the 1,5-electrocyclization back-reaction mechanism, including a partial rotation prior to the final ring closure. (C) 2017 Elsevier B.V.

Synthesis, anti-inflammatory and neuroprotective activity of pyrazole and pyrazolo[3,4-d]pyridazine bearing 3,4,5-trimethoxyphenyl

A new series of 3,4,5-trimethoxyphenyl bearing pyrazole (4a-g) and pyrazolo[3,4-d]pyridazine (5a-g) scaffolds were synthesized in good yield. The newly synthesized compounds were characterized on the basis of elemental and spectroscopic analyses. Their inhibitory activity against the pro-inflammatory inducible nitric oxide synthase and cyclooxygenase-2 proteins expression in lipopolysaccharide-stimulated murine RAW 264.7 macrophages were assessed and showed various potencies. All pyrazolo[3,4-d]pyridazine compounds (5a-g) strongly down regulated lipopolysaccharide inducible nitric oxide synthase expression to the range of 20.3 +/- 0.6-51.3 +/- 3.5% relative to the bioactive pyrazole derivatives 4b, 4c, 4e and 4g. With the exception of inactive compounds 4c and 4d, all other synthesized compounds inhibited cyclooxygenase-2 expression below 100% in the lipopolysaccharide-stimulated cells, which being declined maximally to 42.8 +/- 1.4% by one of the pyrazolo[3,4-d]pyridazine compounds (5d). Moreover, the neuroprotective activity of the less cytotoxic compounds 4b, (4e-g) and (5a-g) were evaluated against 6-hydroxydopamine (6-OHDA)-induced neuroblastoma SH-SY5Y cell death and exhibited significant (p < 0.05) cell protection. The pyrazolo[3,4-d]pyridazine compound (5e) exhibited more than 100% of relative neuroprotection (110.7 +/- 4.3%) with an additional advantage of having the highest cell viability index (107.2 +/- 2.9%).
