Synthesis, structural characterization, and molecular docking study of new phthalhydrazide-coumarin hybrids

A series of new phthalhydrazide-coumarin hybrids was obtained in the reaction of phthalhydrazide with corresponding bromopropoxycoumarin derivatives. These reactions were performed in the presence of Cs2CO3, in acetonitrile as solvent, and under reflux for 5 h. Obtained hybrids contain one or two coumarin scaffolds bonded to phthalhydrazide nitrogen via propoxy linker. Ten new phthalhydrazide-coumarin hybrids were obtained in moderate to good yields, and characterized with melting point, elemental analysis, IR and NMR spectroscopy, and LC-MS spectrometry. Additionally, the structures of these compounds were elucidated based on experimental and theoretical data (IR, H-1 NMR, and C-13 NMR). Excellent agreement between experimental and simulated spectra was achieved. The prediction of the potential biological activity of synthesized compounds was done using the online program PASS (Prediction of Activity Spectra for Substances). Based on the obtained results, the serotonin 2A receptor (5-HT2AR) was selected for molecular docking study. Molecular docking was also performed with commercially available drug Risperidone, and obtained results were compared with potential bioactive conformations of obtained phthalhydrazide-coumarin hybrids.

Inhibition of water adsorption into polar solid-phase microextraction materials with ultrathin polydimethylsiloxane coating for thermal desorption-gas chromatography analysis

Solid-phase microextraction (SPME) coupled with thermal desorption-gas chromatography (TD-GC) has become a powerful analysis tool for volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) in water samples. However, water adsorption into polar microextraction phase is usually unavoidable during the extraction process, and the burst of large amounts of water vapour during thermal desorption will cause serious problems to GC separation and detectors. Pawliszyn’s group had demonstrated that the tens of micron-thick, defect-free polydimethylsiloxane (PDMS) coating could act as a perfect barrier for water adsorption and offer much better compatibility in complex matrices. However, the PDMS overcoat largely decreased the uptake rate of polar analytes into the inner sorbent. In order to quantify the effect of PDMS coating thickness on water adsorption amount and the extraction kinetics, ultrathin PDMS layer was used to coat the polar extraction phase with polyimide (PI) as a model in this work. It was surprising to find that the PDMS coating with the thickness less than one micron can decrease the water adsorption by 96%, while the extraction efficiency for polar analytes (phenolic compounds and nitroaromatic explosives) was decreased by less than 20% at the extraction time of 30 min. Moreover, the kinetic data showed that the thinner the PDMS coating was, the less the uptake rate of polar analytes into PI extraction phase decreased. Finally, polar poly (phthalazine ether sulfone ketone) (PPESK) extraction phase was also coated with ultrathin PDMS coating to verify the universality of the strategy. Generally, the water adsorption problem in polar SPME was overcome to a great extent, and the extraction efficiency of polar analytes was mainly preserved with this ultrathin PDMS coating, which could broaden the application of SPME in the environmental field.

New racemic annulated pyrazolo[1,2-b]phthalazines as tacrine-like AChE inhibitors with potential use in Alzheimer’s disease

A novel series of tacrine-like compounds 7a-u possessing a fused pyrazolo[1,2-b]phthalazine structure were designed and synthesized as potent and selective inhibitors of AChE. The in-vitro biological assessments demonstrated that several compounds had high anti-AChE activity at nano-molar level. The more promising compound 71 with IC50 of 49 nM was 7-fold more potent than tacrine and unlike tacrine, it was highly selective against AChE over BuChE. The cell-based assays against hepatocytes (HepG2) and neuronal cell line (PC12) revealed that 71 had significantly lower hepatotoxicity compared to tacrine, with additional neuroprotective activity against H2O2-induced damage in PC12 cells. This compound could also inhibit AChE-induced and self-induced A beta peptide aggregation. The advantages including synthetic accessibility, high potency and selectivity, low toxicity, adjunctive neuroprotective and A beta aggregation inhibitory activity, make this compound as a new multifunctional lead for Alzheimer’s disease drug discovery.

Phosphoramidates as Transient Precursors of Nitrogen-Centered Radical Under Visible-Light Irradiation: Application to the Synthesis of Phthalazine Derivatives

Phosphoramidates are for the first time presented as efficient N-Centered Radical (NCR) precursors under visible-light irradiation. More precisely among this class of phosphorus-derived compounds, we studied the radical reactivity of phosphonohydrazones, under mild reaction conditions, which allowed the synthesis of a wide and diversified library of the scarcely reported phthalazine scaffold. Mechanistic investigations confirmed the formation of a NCR from these brand-new phosphonohydrazones (derivatived from phosphoramidates), which were further engaged in an intramolecular 6-exo-dig cyclization to provide phthalazines. Compared to other pre-activated moieties, the phosphoramidate group is self-immolative, thus enhancing its attractiveness for the C-N bond formation.

Reactions of phthalazine, quinazoline, 4,7-phenanthroline and 2,3 ‘-bipyridine with ruthenium carbonyl

The reactions of [Ru-3(CO)(12)] with four aromatic diazines have been studied in THF at reflux temperature. With phthalazine (L-1), the compound [Ru-3(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(7)] (1), which contains an intact phthalazine ligand in an axial position bridging an Ru-Ru edge through both N atoms, is initially formed but it reacts with more phthalazine to give [Ru-3(kappa N-2-L-1)(mu-kappa(NN3)-N-2-N-2-L-1)(mu-CO)(3)(CO)(6)] (2), in which a pi-pi stacking interaction between the aromatic rings of both ligands determines their position in cluster axial sites on the same face of the Ru3 triangle. With quinazoline (HL2), the cyclometalated hydrido decacarbonyl derivative [Ru-3(mu-H)(mu-kappa(NC4)-N-2-C-3-L-2)(CO)(10)] (3) is initially produced but it partially decarbonylates under the reaction conditions to give [Ru-6(mu-H)(2)(mu-kappa(NC4)-N-2-C-3-L-2)(mu(3)-kappa(3)-(NNC4)-N-1-C-3-L-2)(CO)(19)] (4), which results from the displacement of a CO ligand of 3 by the uncoordinated N-1 atom of another molecule of 3. With 4,7-phenanthroline (H2L3), the stepwise formation of the cyclometalated derivatives [Ru-3(mu-H)(mu-kappa(NC3)-N-2-C-4-HL3)(CO)(10)] (5) and two isomers of [Ru-6(mu-H)(2)(mu(4)-kappa(NCNC8)-N-4-C-4-N-3-C-7-L-3)(CO)(20)] (6a, 6b) takes place. In compounds 6a and 6b, two Ru-3(mu-H)(CO)(10) trinuclear units are symmetrically (C-2 in 6a or C-S in 6b) bridged by a doubly-cyclometalated 4,7-phenanthroline ligand. With 2,3′-bipyridine (HL4), two products have been isolated, [Ru-3(mu-H)(mu-kappa N-2(3)’ C-4′-L-4)(CO)(10)] (7) and [Ru-3(mu-H)-(mu-kappa(NN3)-N-3-N-2’C-2′-L-4)(CO)(9)] (8). While compound 7 contains an N-3′ C-4′-cyclometalated 2,3′-bipyridine, in compound 8 an N-3′ C-2′-cyclometalation is accompanied by the coordination of the N-2 atom of the remaining pyridine fragment. The structures of compounds 2, 3, 4, 6a and 8 have been determined by X-ray diffraction crystallography.
