Coordination chemistry of thioether-pyridazine macrocycles. III. Synthetic, structural, and spectroscopic studies of Cu(II), Cu(II)Cu(I), and Cu(I) complexes of a hexathiapyridazinophane macrocyclic ligand

The preparation and properties of the thioether-pyridazine macrocycle (L4; C16H20S6N4) containing two pyridazine subunits, and its Cu(II), Cu(II)Cu(I), and Cu(I) complexes are described.The ligand is characterized by 1H nuclear magnetic resonance and mass spectrometry, and the complexes by infrared, electronic spectra, and magnetism, and in some cases by X-ray crystallography.The complex x (1) crystallized in the triclinic system, space group P<*> with a=8.6204(8) Angstroem, b=9.850(1) Angstroem, c=8.348(1) Angstroem, alpha=111.46(1)o, beta=102.50(1)o, gamma=71.818(9)o, V=622.6(1) Angstroem3, and Z=1 (R=0.043, Rw=0.042 for 1312 reflections).Two monodentate pyridazine rings in the same ligand bind to one trans square-planar copper centre (CuN2Cl2) with two sulfurs from each ligand binding to another trans square-planar copper centre (CuS2Cl2) to form a plynuclear chain.The complex (3) crystallized in the triclinic system, space group P<*>, with a=11.001(1) Angstroem, b=12.888(2) Angstroem, c=8.704(1) Angstroem, alpha=102.89(1)o, beta=103.36(1)o, gamma=75.84(1)o, V=1145.8(3) Angstroem3, and Z=2 (R=0.056, Rw=0.044 for 2059 reflections).A trans square-planar structure (CuN2Cl2) exists for 3 with monodentate pyridazines. (4) crystallized in the orthorhombic system, space group P212121, with a=15.148(2) Angstroem, b=15.562(3) Angstroem, c=11.064(1) Angstroem, V=2608.2(7) Angstroem3, and Z=4 (R=0.039, Rw=0.034 for 1864 reflections).Two monodentate pyridazine rings and two bidentate nitrates bind to a pseudo-octahedral copper(II) centre.

A series of novel ([1,2,4]triazolo[1,5-b]pyridazin-6- yl)oxyalkylsulfonamides was synthesized and evaluated for the ability to inhibit platelet activating factor (PAF)-induced bronchoconstriction in guinea pigs. The compounds bearing a gem-dialkyl or a cycloalkylidene group at the 2 position of the sulfamoylpropyloxy group in the side chain and a methyl group at the 7 position were found to have potent activity. Among them, 2,2-diethyl-3-(7-methyl[l,2,4]-triazolo[1,5-b]pyridazin-6- yl)oxypropanesulfonamide (13) showed excellent anti-asthmatic activity. Compouds 13 may be of significant value in the treatment of asthma and other respiratory diseases. The structure-activity relationships in this series of compounds are discussed.

Synthesis and Structure-Activity Relationships of Series of Aminopyridazine Derivatives of gamma-Aminobutyric Acid Acting as Selective GABA-A Antagonists

We have recently shown that an aryloaminopyridazine derivarive of GABA, SR 95103 <2-(3-carboxypropyl)-3-amino-4-methyl-6-phenylpyridazinium chloride>, is a selective and competitive GABA-A receptor antagonist.In order to further explore the structural requirements for GABA receptor affinity, we synthesized a series of 38 compounds by attaching various pyridazinic structures to GABA or GABA-like side chains.Most of the compounds displaced <3H>GABA from rat brain membranes.All the active compounds antagonized the GABA-elicited enhancement of <3H>diazepam binding, strongly suggesting that all these compounds are GABA-A receptor antagonists.None of the compounds that displaced <3H>GABA from rat brain membranes interacted with other GABA recognition sites (GABA-B receptor, GABA uptake binding site, glutamate decarboxylase, GABA-transaminase).They did not interact with the Cl- ionophore associated with the GABA-A receptor and did not interact with the benzodiazepine, strychnine, and glutamate binding sites.Thus these compounds appear to be specific GABA-A receptor antagonists.In terms of structure-activity, it can be concluded that a GABA moiety bearing a positive charge is necessary for optimal GABA-A receptor recognition.Additional binding sites are tolerated only if they are part of a charge-delocalized amidinic or guanidinic system.If this delocalization is achieved by linking a butyric acid moiety to the N(2) nitrogen of a 3-aminopyridazine, GABA-antagonistic character is produced.The highest potency (ca.250 times bicuculline) was observed when an aromatic ? system, bearing electron-donating substituents, was present on the 6-position of the pyridazine ring.

Delocalized aromatic molecules with matched electron-donating and electron-withdrawing groups enhancing insulating performance of polyethylene blends

Seven delocalized aromatic molecules with electron-donating and electron-withdrawing groups are applied as voltage stabilizers to improve the insulation properties of polyethylene blends. Voltage stabilizers 1 wt% are added into the blends (90 wt% low-density polyethylene and 10 wt% high density polyethylene) by diffusion loading method. Electrical measurements including electrical treeing, space charge distribution, and direct current conductivity are conducted to disclose their effects. The results show that the co-existence of matched electron-donating and electron-withdrawing groups in the molecules is favorable for the insulation properties. A 50% increase of tree initiation voltage is achieved with the addition of 3-aminobenzoic acid, which is also able to inhibit the space charge and decrease the conductivity at lower temperature. Besides, the grafting sample of the optimal molecule is successfully prepared and displayed enhanced electrical properties. Finally, the common internal mechanism of the delocalized molecules on different electrical properties is revealed.
