Discovery and synthesis of novel allylthioaralkylthiopyridazines: their antiproliferative activity against MCF-7 and Hep3B cells

A new series of 6-allylthio-3-aralkylthio-4,5-dimethylpyridazines 5a-5k and 1-allylthio-4-alkylthio5,6,7,8-tetrahydrophthalazine 6a-6j was synthesized from maleic anhydride derivatives for development of new anticancer agents. The process involves the formation of pyridazine and phthalazine rings, dichlorination, allylthiolation, and aralkylthiolation. These new compounds showed antiproliferative activities against breast cancer (MCF-7) and hepatocarcinoma (Hep3B) cells in CCK-8 assays, and could be promising candidates for chemotherapy of carcinomas. Among 21 synthesized compounds, five compounds (5a, 5b, 6b, 6d, and 6f) showed higher potency than 5-FU for inhibiting the growth of cell line. The results indicated that compound 6f had the highest activity towards MCF-7 and Hep3B cells. These results suggest the potential anticancer activity of compounds 5a, 5b, 6b, 6d, and 6f.

A New Pathway for Phthalazine Derivatives via Metal-Free Cyclization of ortho-Alkynylphenyl Ketones and Hydrazine

A one-step synthetic protocol for phthalazine derivatives has been developed. In the presence of Et3N, a series of phthalazine derivatives were conveniently prepared in high yield by the reaction of ortho-alkynylphenyl ketones and hydrazine under mild reaction conditions. The structure was unambiguously confirmed by X-ray crystallographic analysis of product 2i.

Green synthesis of 1H-pyrazolo[1,2-b]phthalazine-2-carbonitrile derivatives using a new bifunctional base-ionic liquid hybrid magnetic nanocatalyst

The ionic liquid-base N,N,2,2,6,6-hexamethyl-N-(3-(trimethoxysilyl)propyl)piperidin-4-amonium iodide was grafted onto titana-coated NiFe2O4 nanoparticles for obtaining an efficient and reusable ionic liquid-base hybrid nanocatalyst. The structure of hybrid nanoparticles was characterized using FT-IR (Fourier-transform infrared spectroscopy), field emission scanning electron microscopy, EDS (energy-dispersive X-ray spectroscopy), EDS map scan, Brunauer-Emmett-Teller surface area analysis, CHN (elemental analysis), vibrating sample magnetometer and thermogravimetric analysis techniques. Furthermore, this novel hybrid catalyst was used in one-pot three-component synthesis of 3-amino-1-aryl-5,10-dioxo-1H-pyrazolo[1,2-b]phthalazine-2-carbonitrile derivatives under green and environmentally benign conditions. This protocol avoids the use of harmful catalysts, toxic solvents and harsh reaction conditions. The products were synthesized in excellent yields within short reaction time and identified using elemental analysis, FT-IR, H-1 NMR and C-13 NMR spectroscopies.

Tailoring Dihydroxyphthalazines to Enable Their Stable and Efficient Use in the Catholyte of Aqueous Redox Flow Batteries

To enable cost-efficient stationary energy storage, organic active materials are the subject of current investigations with regard to their application in aqueous redox flow batteries. Especially quinones quinones with their beneficial electrochemical properties and natural abundance pose a promising class of compounds for this challenging endeavor. Yet, there are not many active materials available for the catholyte side to realize solely quinone-based systems. Herein we introduce the novel hydroquinone 5,8-dihydroxy-2,3-phthalazine together with two of its derivatives and propose it as a promising active material for the catholyte side of aqueous redox flow batteries. We systematically investigate the electrochemical properties as well as the structure-property relationship of this class of compounds. The unmodified dihydroxyphthalazine exhibits a favorably high redox potential of 796 mV vs SHE in acidic solution that is competitive with benzoquinone compounds. Moreover, the introduced dihydroxyphthalazines feature a high electron transfer rate surpassing benzoquinone species by almost one order of magnitude. With regard to stable cycling performance, we further achieved a high resilience against detrimental side reactions such as Michael addition by adding methyl substituents to the base structure. Our experimental findings are supported and extended by theoretical considerations in terms of density functional theory calculations. With this combined approach we outline further promising dihydroxyphthalazine-based materials with regard to performance-relevant quantities like redox potential, cycling stability, and water solubility. This study aims to propel further research in the field of quinone-based active materials for the catholyte of future aqueous redox flow batteries.

A high-strength PPESK/PVDF fibrous membrane prepared by coaxial electrospinning for lithium-ion battery separator

Electrospinning fibrous membranes have attracted a great deal of attention because of their advantages, including uniform pore size, large ratio surface area, and high porosity. For extended application in lithium-ion battery, it is essential to further improve their electrochemical, mechanical, and thermal properties. In this work, a new poly (phthalazine ether sulfone ketone) (PPESK)/polyvinyli-denefluoride (PVDF) core/shell fibrous membrane was fabricated via the coaxial electrospinning technique, followed by hot press. The PPESK/PVDF membrane hot pressed at 160 degrees C exhibits excellent comprehensive performance, including large porosity (80%), high electrolyte uptake (805%), and excellent thermal stability (at 200 degrees C). Moreover, due to the improved bonding effect derived from the solidification of the PVDF shell layer after the hot press, the mechanical property of the membrane is effectively enhanced. The electrochemical tests also indicate that the PPESK/PVDF membrane shows larger ionic conductivity and lower interfacial resistance when compared with commercial microporous polypropylene separator. In addition, simulated cells assembled with the PPESK/PVDF membrane present superior discharge capacity, stable cycle performance, and excellent rate capability. Therefore, the hot-pressed coaxial PPESK/PVDF fibrous membrane has the potential to be a promising candidate as the separator for high-performance lithium-ion battery.
