6-phenylpyridazin-3(2H) one as New Corrosion Inhibitor for C38 Steel in 1 M HCl

The corrosion behavior of C38 steel in HCl solutions and its inhibition by 6-phenylpyridazin-3(2H) one (PPO) has been studied in different temperature using polarization and electrochemical impedance spectroscopy (EIS) techniques as well as weight loss measurements. The 6-phenylpyridazin-3(2H) one has shown good inhibitive properties and acts as mixed inhibitor as observed in polarization method. The EIS results confirmed the efficiency of tested inhibitor and showed that the charge transfer resistance increase with the rise in the concentration following the same trend of the inhibition efficiency. The effect of the temperature, Langmuir adsorption isotherm and their parameters are discussed to examine the mechanism of the interactions between metal surface and tested compound. A chemisorption mechanism is proposed.

Synthesis and discovery of triazolo-pyridazine-6-yl-substituted piperazines as effective anti-diabetic drugs; evaluated over dipeptidyl peptidase-4 inhibition mechanism and insulinotropic activities

A family of 12 triazolo-pyridazine-6-yl-substituted piperazines (5a-1) was synthesized and evaluated for their Dipeptidyl peptidase-4 (DPP-4) inhibition potentials in order to develop them as anti-diabetic medications. In the two-step synthesis process, 6-chloro-3-(m-tolyl)-[1,2,4]triazolo[4,3-b]pyridazine was synthesized with one-pot mode using pyridine, 3,6-dichloropyridazine 5-(3-methyl-phenyl)tetrazole in toluene.

DPP-4 inhibition potential of these compounds was testified in silico and in nitro along with their insulinotropic activities in 832/13 INS-1 cells. H2O2 radical scavenging assay and MTT assay were conducted to assess the anti-oxidant and cytotoxicity of these compounds respectively. Molecular docking and. ELBA based enzyme inhibition assay results revealed the strong inhibition potential of the target compounds. MTT assay results indicated a maximum dose of 2.5 nM (IC50 1.25 nM) could be used and above this level vital for the cells. Compounds 5a, 5c, 5g and 5i were found with excellent antioxidant and insulinotropic activity up to 99%. (C) 2019 Elsevier Masson SAS. All rights reserved.

[1,2,5]Thiadiazolo[3,4-d]Pyridazine as an Internal Acceptor in the D-A–A Organic Sensitizers for Dye-Sensitized Solar Cells

Four new D-A–A metal-free organic sensitizers for dye-sensitized solar cells (DSSCs), with [1,2,5]thiadiazolo[3,4-d]pyridazine as internal acceptor, thiophene unit as -spacer and cyanoacrylate as anchoring electron acceptor, have been synthesized. The donor moiety was introduced into [1,2,5]thiadiazolo[3,4-d]pyridazine by nucleophilic aromatic substitution and Suzuki cross-coupling reactions, allowing design of D-A–A sensitizers with the donor attached to the internal heterocyclic acceptor not only by the carbon atom, as it is in a majority of DSSCs, but by the nitrogen atom also. Although low values of power conversion efficiency (PCE) were found, a few important consequences were identified: (i) poor PCE data can be attributed to high electron deficiency of the internal [1,2,5]thiadiazolo[3,4-d]pyridazine acceptor due to lower light harvesting by the dye; (ii) the manner in which the donor was attached to the internal acceptor (by carbon or nitrogen) did not play an essential role in the photovoltaic properties of the dyes; (iii) dyes based on the novel donor 2,3,4,4a,9,9a-hexahydro-1H-1,4-methanocarbazolyl and 9-(p-tolyl)-2,3,4,4a,9,9a-hexahydro-1H- carbazole moieties showed similar photovoltaic properties to dyes based on the well-known 4-(p-tolyl)-1,2,3,3a,4,8b-hexahydrocyclopenta[b]indolyl building block, which opens the door for further optimization potential of new dye families.

Theoretical investigations on novel energetic salts composed of 4-nitro-7-(4-nitro-1,2,3-triazol-1-olate)-furazano[3,4-d]pyridazine-based anions and ammonium-based cations

Based on density functional theory and volume-based thermodynamics methods, the crystal densities (rho), heats of formation (HOFs), detonation performance, specific impulse (I-sp), impact sensitivities (H-50) and Gibbs free energies of formation of eight series novel energetic salts composed of 4-nitro-7-(4-nitro-1,2,3-triazol-1-olate)-furazano[3,4-d] pyridazine-based anions and ammonium-based cations were studied. Results show that all title salts possess high rho and positive HOFs. Therein, ammonium and hydroxylammonium salts exhibit the highest rho and detonation performance in each series and several even surpass those of HMX and RDX. For guanidinium-based salts in every series, when the number of -NH2 group in cations increases, the HOFs, I-sp and H-50 of corresponding salts improve, but their rho values decrease. Consequently, detonation performance of guanidinium-based salts are close to each other (H series are similar to RDX). Otherwise, introducing N -> O oxidation bond to anions is an effective method to improve rho, detonation performance and I-sp of the corresponding salts compared A with B-H series, but it decreases H-50. However, all guanidinium-based salts show lower impact sensitivities than RDX and HMX. Meanwhile, the position of N -> O oxidation bond also has an effect on these properties. (C) 2018 Elsevier B.V.

Novel coumarin-pyridazine hybrids as selective MAO-B inhibitors for the Parkinson’s disease therapy

The 3-pyridazinylcoumarin scaffold was previously reported as an efficient core for the discovery of reversible and selective inhibitors of MAO-B, a validated drug target for PD therapy which also plays an important role in the AD progress. Looking for its structural optimization, novel compounds of hybrid structure coumarin-pyridazine, differing in polarizability and lipophilicity properties, were synthesized and tested against the two MAO isoforms, MAO-A and MAO-B (compounds 17a-f and 18a-f). All the designed compounds selectively inhibited the MAO-B isoenzyme, exhibiting many of them IC50 values ranging from sub-micromolar to nanomolar grade and lacking neuronal toxicity. The 7-bromo-3-(6-bromopyridazin-3-yl)coumarin (18c), the most potent compound of these series (IC50 = 60 nM), was subjected to further in vivo studies in a reserpine-induced mouse PD model. The obtained results suggest a promising potential for 18c as antiparkinsonian agent. Molecular modeling studies also provided valuable information about the enzyme-drug interactions and the potential pharmacokinetic profile of the novel compounds.

Spectroscopic (FT-IR, FT-Raman, UV-Vis) analysis, conformational, HOMO-LUMO, NBO and NLO calculations on monomeric and dimeric structures of 4-pyridazinecarboxylic acid by HF and DFT methods

In this study, the Fourier transform infrared (FT-IR) and Fourier transform Raman (FT-Raman) spectra of 4-pyridazinecarboxylic acid (4PCA) in solid phase were recorded and analyzed. Quantum chemical calculations of the optimized molecular structure, energies, conformational, UV-Vis, nonlinear optical (NLO) and natural bond orbital (NBO) analysis, molecular surfaces, Mulliken charges, and vibrational studies for 4PCA were performed using the ab initio Hartree-Fock (HF) and density functional theory (DFT/B3LYP) methods with 6-311++G(d,p) basis set. Obtained results on the geometric structure and vibrational frequencies are compared with observed data. The dimeric structure of 4PCA with DFT/B3LYP/6-311++G(d,p) level caused by the shifts of O-H and C=O bands in the vibrational spectra of 4PCA were also studied. Moreover, the spectroscopic and theoretical results were compared with the corresponding properties for monomeric and dimeric structures of 4PCA. The calculated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies also confirm that charge transfer occurs within the molecule. NBO analysis confirms the presence of intramolecular charge transfer and the hydrogen bonding interaction. The detailed vibrational assignments were performed with the HF and DFT calculations, and the potential energy distribution (PED) was obtained by the Vibrational Energy Distribution Analysis (VEDA4) program.
