New insights on the arylpiperazinylalkyl pyridazinone ET1 as potent antinociceptive and anti-inflammatory agent

Pyridazine derivatives, such as arylpiperazinylalkyl pyridazinones, display antinociceptive effects to thermal and chemical stimuli. Here, we extended our previous knowledge on the pharmacological profile of 4-amino-6-methyl-2-(3-(4-(4-methylcyclohexa-1,3-dien-1-yl)piperazin-1-yl)propyl)-5-vinylpyridazin-3(2H)-one, here referred as ET1, paving the way for the comprehension of its complete mechanism of action. To this aim, we have evaluated the mouse behavioural responses in several animal models of pain, the effect of ET1 in the murine model of zymosan-induced paw oedema and air-pouch, assessing the cytokines and the cellular phenotype and finally, an in vitro radioligand binding study was performed on a panel of 30 different receptors. In the formalin test, ET1 reduced both neurogenic and inflammatory phase of nociception induced by the aldehyde. Similarly, ET1 strongly reduced paw licking response in the capsaicin test, the abdominal stretching in the writhing test and the carrageenan-induced thermal hyperalgesia. ET1 also evoked a long-lasting reduction of thermal hyperalgesia. Furthermore, ET1 produced a long-lasting anti-inflammatory effect in the zymosan-induced mouse paw oedema and air-pouch through the selective inhibition of inflammatory monocytes recruitment and the modulation of IL-1 beta, IL-6, TNF-alpha and MCP-1. Binding experiments confirmed an inhibitory effect on adrenergic alpha(1A), alpha(1B) and alpha(2A) receptors subtypes and, for the first time, a moderate affinity was observed for the following receptors: histamine H-1, imidazoline I-2, sigma non-opioid intracellular receptor 1 and sigma(2). These results prompt ET1 as a potent analgesic and anti-inflammatory agent, and support the possibility that it may be suitable for clinical applications in a wide-range of inflammatory-based diseases.

Heteroleptic beta-diketonate Ln(iii) complexes decorated with pyridyl substituted pyridazine ligands: synthesis, structure and luminescence properties

A substituted pyridazine was used to construct a family of mononuclear heteroleptic complexes [Ln(tta)(3)(dppn)], Ln = Pr-Lu; Htta = thenoyltrifluoroacetone; dppn = 3,6-di(2-pyridyl)pyridazine. All the complexes obtained were characterized by CHN elemental analysis, NMR spectroscopy, ESI mass spectrometry, FTIR spectroscopy and single crystal X-ray analysis. The photophysical properties of lanthanide complexes were carefully investigated, and the dppn ligand was found to act as a chromophore centre to sensitize metal-centred emission of the Nd, Sm, Eu, and Yb complexes under UV excitation. It has been shown that a powder sample of the Eu complex can contain two isomers with somewhat different symmetries of the environment of the metallocentre. The mechanism for the emission of luminescent Nd, Sm, Eu, and Yb complexes was investigated by TDDFT calculations and the results confirmed the conclusion made on the basis of experimental data regarding the likely pathway of energy transfer from the chromophore centre to the emissive level of Ln(iii).

Inhibition Mechanisms of a Pyridazine-Based Amyloid Inhibitor: As a beta-Sheet Destabilizer and a Helix Bridge Maker

Conformational diseases have been investigated extensively in recent years; as a result, a number of drug candidates have been introduced as amyloid inhibitors; however, no effective therapies have been put forward. RS-0406 with pyridazine as its core chemical structure has so far shown promising results in inhibiting amyloid formation. In the present work, using molecular dynamics, we undertook the investigation of RS-0406 interactions with U-shaped A beta(1-42) and A beta(1-40) pentamers, A beta(1-42) monomers, and double-horseshoe-like A beta(1-42). To set better parameters for the small molecule, experimental and computational log?P values were obtained. In addition, an analogue of RS-0406 was also simulated for comparison. The results indicate that RS-0406 may inhibit amyloid formation exploiting two different mechanisms. One mechanism includes stabilizing the alpha helix, in the monomer peptide, by binding to the flanking sites of the amyloidogenic region. The second mechanism mediates through interaction of the small molecules near the amyloidogenic regions, leading to destabilization of the beta-sheets in both the U-shaped and the S-shaped fibril. Notably, a persistent interaction between the imidazole ring of His14 from an S-shaped structure and the pyridazine ring of RS-0406 was observed. The unique structural properties of RS-0406, including aromaticity, H-bonding capability, flexibility, and symmetry, allow the small molecule to noticeably affect amyloid formation.

A diazabenzoperylene derivative as ratiometric fluorescent probe for cysteine with super large Stokes shift

Biothiols, including cysteine (Cys), homocysteine (Hcy), and glutathione (GSH), play key roles in biological processes, and detecting such thiols selectively is critical for understanding functions of biothiols. In this work, a pyridazine annelated perylene-based fluorescent probe PAPC is synthesized for highly selective detection of Cys. PAPC exhibits strong blue emission in PBS, while the red emission at 605 nm can be observed in the presence of Cys. The probe PAPC shows ratiometric fluorescence (I-605/I-460) detection of Cys with wide linear range of 1-120 mu M and low detection limit of 0.19 mu M. Super large Stokes shift (170 nm) and ratiometric fluorescence endow the probe low background signal. The discrimination of Cys over Hcy and GSH can be achieved through the difference of the ratiometric fluorescence. In addition, the probe has been proven to track Cys in real samples such as urine and HeLa cells. Therefore, PAPC probe is a promising candidate for detecting Cys in practical application.

Synthesis of O-6-Corona[3]arene[3]pyridazines and Their Molecular Recognition Property in Organic and Aqueous Media

O-6-Corona[3]arene[3]pyridazines were synthesized from the one-pot macrocyclic condensation reaction of 3,6-dichlorotetrazine with 1,4-dihydroquinone derivatives followed by the inverse electron demand Diels-Alder reaction of the tetrazine rings with a cyclopentanone-derived enamine. Conversion of six ester groups within macrocycle into all sodium acetate moieties afforded a water soluble O-6-corona[3]arene[3]pyridazine. The coronary macrocycle host formed complexes selectively with organic ammoniums and dinitrile guests in a 1: 1 stoichiometric ratio in organic solvents with association constants ranging from (2.96 +/- 0.10)x10(1) to (2.53 +/- 0.33)x10(5)Lmol(-1). Water soluble O-6-corona[3]arene[3]pyridazine was also able to complex strongly with organic ammoniums in water to give an association constant up to (2.67 +/- 0.21)x10(4)Lmol(-1). The pseudo-rotaxane and inclusion structures of the host-guest complexes were revealed by the X-ray crystallography.

Blue Fluorescence from BF2 Complexes of N,O-Benzamide Ligands: Synthesis, Structure, and Photophysical Properties

Small molecules having intense luminescence properties are required to promote biological and organic material applications. We prepared five types of benzamides having pyridine, pyridazine, pyrazine, and pyrimidine rings and successfully converted them into three types of the difluoroboronated complexes, Py@BAs, as novel blue fluorophores. Py@BA having a pyridine moiety (2-Py@BA) showed no fluorescence in solution, whereas Py@BAs of pyridazine and pyrazine moieties (2,3-Py@BA and 2,5-Py@BA, respectively) emitted blue fluorescence with quantum yields of ca. 0.1. Transient absorption measurements using laser flash photolysis of the Py@BAs revealed the triplet formation of 2,3- and 2,5-Py@BAs, while little transient signal was observed for 2-Py@BA. Therefore, the deactivation processes from the lowest excited singlet state of fluorescent 2,3- and 2,5-Py@BAs consist of fluorescence and intersystem crossing to the triplet state while that of the nonfluorescent Py@BA is governed almost entirely by internal conversion to the ground state. Conversely, in the solid state, 2-Py@BA emitted intense fluorescence with a fluorescence quantum yield as high as 0.66, whereas 2,3- and 2,5-Py@BAs showed fluorescence with quantum yields of ca. 0.2. The crystal structure of 2-Py@BA took a herringbone packing motif, whereas those for 2,3- and 2,5-Py@BAs were two-dimensional sheetlike. On the basis of the difference in crystal structures, the emission mechanism in the solid state was discussed.

Photochromism of Dihydroindolizines. Part XXI: Multiaddressable Photochromic Performances based on Pyrrolo[1,2-b]pyridazine photochromes: Kinetics, Substituent Effect and Solvatochromism

In the present study, the thermal 1,5-electrocyclization back reaction from betaines (colored forms) to dihydroindolizines (DHIs, colorless) was studied in seven organic solvents with different polarities at various temperatures. The spectroscopic, thermodynamic and photochromic properties of such photo and solvatochromic material based on betaines/DHIs is investigated. It is obvious that the rate of the thermal back reaction depend on solvent polarity. Exploration of the activation parameters unravel an underlying compensation between Delta H-not equal and Delta S-not equal. The 1,5-electrocylization decoloration reaction is found to follow two-step mechanism, the first step corresponds to the transoid-cisoid isomerization and the second one is the ring closure from the cisoid intermediate and formation of the carbon-carbon bond to form the initial Spiro isomer. The special solvent effects were discussed based on the linear free energy relationship. The solvatochromism of the dihydroindolizines (DHIs) was studied and analyzed by means of the empirical Kamlet-Taft and Catalan solvent parameter set. The obtained results suggest that the change of polarizability within the solvents is the major factor for the observed solvent dependence. (C) 2017 Elsevier B.V. All rights reserved.

Pyridazinone-substituted benzenesulfonamides display potent inhibition of membrane-bound human carbonic anhydrase IX and promising antiproliferative activity against cancer cell lines

An expanded set of pyridazine-containing benzene sulfonamides was investigated for inhibition of four human carbonic anhydrase isoforms, which revealed a pronounced inhibition trend toward hCA IX, a cancer-related, membrane-bound isoform of the enzyme. Comparison of antiproliferative effects of these compounds against cancer (PANC-1) and normal (ARPE-19) cells at 50 mu M concentration narrowed the selection of compounds to the eight which displayed selective growth inhibition toward the cancer cells. More detailed investigation in concentration-dependent mode against normal (ARPE-19) and two cancer cell lines (PANC-1 and SK-MEL-2) identified two lead compounds one of which displayed a notable cytotoxicity toward pancreatic cancer cells while the other targeted the melanoma cells. These findings significantly expand the knowledge base concerning the hCA IX inhibitors whose inhibitory potency against a recombinant enzyme translates into selective anticancer activity under hypoxic conditions which are aimed to model the environment of a growing tumor.
