TPA-023 attenuates subchronic phencyclidine-induced declarative and reversal learning deficits via GABA(A) receptor agonist mechanism: possible therapeutic target for cognitive deficit in schizophrenia

GABAergic drugs are of interest for the treatment of anxiety, depression, bipolar disorder, pain, cognitive impairment associated with schizophrenia (CIAS), and other neuropsychiatric disorders. Some evidence suggests that TPA-023, (7-(1,1-dimethylethyl)-6-(2-ethyl-2H-1,2,4-triazol-3-ylmethoxy)-3-(2-fluorophenyl)-1,2,4-triazolo[4,3-b] pyridazine), a GABA(A) a2,3 subtype-selective GABA(A) partial agonist and alpha(1/5) antagonist, and the neurosteroid, pregnenolone sulfate, a GABA(A) antagonist, may improve CIAS in pilot clinical trials. The goal of this study was to investigate the effect of TPA-023 in mice after acute or subchronic (sc) treatment with the N-methyl-D-aspartate receptor (NMDAR) antagonist, phencyclidine (PCP), on novel object recognition (NOR), reversal learning (RL), and locomotor activity (LMA) in rodents. Acute TPA-023 significantly reversed scPCP-induced NOR and RL deficits. Co-administration of sub-effective dose (SED) TPA-023 with SEDs of the atypical antipsychotic drug, lurasidone, significantly potentiated the effect of TPA-023 in reversing the scPCP-induced NOR deficit. Further, scTPA-023 co-administration significantly prevented scPCP-induced NOR deficit for 5 weeks. Also, administration of TPA-023 for 7 days following scPCP reversed the NOR deficit for 1 week. However, TPA-023 did not blunt acute PCP-induced hyperactivity, suggesting lack of efficacy as a treatment for psychosis. Systemic TPA-023 significantly blocked lurasidone-induced increases in cortical acetylcholine, dopamine, and glutamate without affecting increases in norepinephrine and with minimal effect on basal release of these neurotransmitters. TPA-023 significantly inhibited PCP-induced cortical and striatal dopamine, serotonin, norepinephrine, and glutamate efflux. These results suggest that TPA-023 and other GABA(A) agonists may be of benefit to treat CIAS.

Identification of 2-substituted pyrrolo[1,2-b]pyridazine derivatives as new PARP-1 inhibitors

A library of new 2-substituted pyrrolo[1,2-b]pyridazine derivatives were rapidly assembled and identified as PARP inhibitors. Structure-activity relationship for this class of inhibitor resulted in the discovery of most potent compounds 15a and 15b that exhibited about 29- and 5- fold selective activity against PARP-1 over PARP-2 respectively. The antiproliferative activity of the as-prepared compounds were demonstrated by further celluar assay in BRCA2-deficient V-C8 and BRCA1-deficient MDA-MB-436 cell lines, displaying that compound 15b could robustly reduce the corresponding cell proliferation and growth with CC(50)s of 340 and 106 nM respectively. The PK property of 15b was also investigated here.

Photochromism of dihydroindolizines. Part XXII: Significant effect of region B substituents on tuning the photophysical properties of photochromic dihydroindolizines: Absorption, kinetic and computational studies

Novel photochromic dihydroindolizines (DHIs) bearing different alkyl and cyclic alkyl ester group (region B) were prepared via electrophilic addition of fluorene spirocyclopropenes substituted with different alkyl ester groups in region B of the DHI skeleton to N-heterocyclic pyridazine in dry ether solution. The maxima of absorption (Amax) of the colored betaines (formed after UV-irradiation) were detected by UV/ Vis absorption measurement. The studied betaines showed one visible region absorption maxima between 517 and 548 nm. The kinetics of the 1,5-electrocyclization process of the colored betaines to closed DHIs system was studied spectrophotometrically in dichloromethane solution. Interestingly, a significant decrease in the half-life time by a factor of 8 was observed when alkyl of the ester group changed from methyl to pentyl alkyl groups. The activation parameters indicated that the changes of Olio are counterbalanced by changes in AS compensation effect. The enthalpy and entropy of the activation energies for the thermal back-reaction were compared to investigate the generalization and the limitation of the molecular intention of the photochromic DHIs lengthways with the correlation between unwieldiness of the substituents (region B) and the rate constant of the thermal back-reaction. DFI’ calculations are performed to explain the 1,5-electrocyclization back-reaction mechanism, including a partial rotation prior to the final ring closure. (C) 2017 Elsevier B.V.

Evaluation of Biophysical Interaction between Newly Synthesized Pyrazoline Pyridazine Derivative and Bovine Serum Albumin by Spectroscopic and Molecular Docking Studies

In this research, the pyrazoline pyridazine derivative 7-methyl-2-phenyl-4-(3,4,5-trimethoxyphenyl)-2H-pyrazolo[3,4-d]pyridazine (5d) was studied for its interaction with bovine serum albumin (BSA). Various spectroscopic techniques along with molecular docking analysis were utilized to understand the mechanism of interaction. The quenching of BSA fluorescence by using investigational drug 5d was the basic principle for the methodology. Spectrofluorometric methods and UV-absorption studies were conducted for exploration of the 5d and BSA binding mechanism. The fluorescence quenching mechanism involved in BSA and 5d interaction was static quenching, and a complex formation also occurred between them. Both enthalpy and entropy attained positive values suggesting involvement of hydrophobic forces in BSA and 5d interaction. The Forster distance of 2.23nm was calculated by fluorescence resonance energy transfer (FRET). An alteration in BSA secondary structure was proven from the conformational studies of BSA-5d interaction. This binding interaction study provided a basis to comprehend the binding interaction between 5d and BSA. These results provided information about sites of BSA involved in its interaction with 5d.

Photodegradation of methylene blue by photocatalyst of D-A-D type polymer/functionalized multi-walled carbon nanotubes composite under visible-light irradiation

A donor-acceptor-donor (D-A-D) type monomer (3,6-bis(2-(3,4-ethylenedioxy-thiophene))pyridazine) (EPE) with pyridazine as intermediate unit (acceptor) and 3,4-ethylenedioxythiophene (EDOT) as sealing unit (donor) was successfully synthesized. The functionalized multi-walled carbon nanotubes (f-MWCNT) was covalently linked with polymer chain via chemical oxidative polymerization of monomer EPE to form poly(EPE)/f-MWCNT composite. The prepared composite was characterized by Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-visible absorption spectra (UV-vis), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), and Field emission scanning electron microscope (FESEM), respectively. The photocatalytic activity of poly(EPE)/f-MWCNT was investigated toward degrading methylene blue (MB) dye solution (1 x 10(-5) M) under visible light irradiation. As expected, the degradation efficiency of poly(EPE)/f-MWCNT is significantly higher than that of either pure poly(EPE) or poly(EPE)/MWCNT for MB dye, especially the kinetic constant of poly(EPE)/f–MWCNT is more than 6 times of poly(EPE)/MWCNT. Besides, the reactive oxygen species trapping experiments indicate that the degradation of MB over the poly(EPE)/f-MWCNT composite mainly results from holes oxidation. Moreover, the enhancement of the photodegradation rate is mainly attributed to the superior stability, strong light absorption ability, and highly effective photo-generated electron-hole pairs of the poly(EPE)/f-MWCNT composite. A reasonable mechanism for the enhanced reactivity was proposed. (C) 2016 Published by Elsevier Ltd.

Synthesis and characterization of a novel supported N-piperidine sulfamic acid on magnetic nanoparticles as a nanocatalyst for synthesis of pyrimido[4,5-c]pyridazines derivatives under ambient conditions and theoretical study on the mechanism using a DFT method

In this study, magnetic nanoparticles (Fe3O4 NPs) were employed as good support for N-piperidine sulfamic acid to prepare a novel nanocatalyst (SA-PPCA-Fe3O4 NPs). This nanocatalyst was then characterized by different techniques such as FT-IR, XRD, TGA, SEM, TEM and VSM. The catalytic activity of the SA-PPCA-Fe3O4 NPs was studied by one-pot preparation of pyrimido[4,5-c]pyridazines derivatives from three-component reactions of 1,3-dimethylthiobarbituric acid or 1,3-diethylthiobarbituric acid with different arylglyoxals and hydrazine monohydrate at ambient conditions. SA-PPCA-Fe3O4 NPs exhibited excellent advantages such as simplicity, high yields, short reaction time, easily separation using an external magnet, bio eco-friendly and recoverability and reusability with no remarkable loss of catalytic efficiency. In this work, density functional theory and modeling were reported to investigate of mechanism of the reaction. In fact, this study gives an insight into the mechanism of the pyrimido[4,5-c]pyridazines reaction in the presence of nanocatalyst of SA-PPCA-Fe3O4 NPs. Graphic abstract

Second hyperpolarizability of diffuse-electron compounds M-NH3, M-NLi3 and M-NLi3-M of alkaline earth metals: Effect of lithiation

Present investigation demonstrates that push electron effect of nitrogen in M center dot center dot center dot NH3 is reduced rather than enhanced upon lithiation which has been explained by natural bond orbital analysis showing that nitrogen atom in NLi3 changes it’s state of hybridization from sp(3) to sp(2) leaving the 2p(z), orbital partially occupied. This makes NLi3 a weak acceptor of electrons from alkaline earth metals. When the second alkaline earth metal is introduced the 2p(z), orbital of nitrogen attains the maximum occupation as a result of cumulative charge transfer from two metal atoms. However, the push electron effect still operates resulting in the diffuse electron localized over the metals. Large enhancement of second hyperpolarizability (10(6) au) in M center dot center dot center dot NLi3 has been rationalized by its low lying intense transitions. Effect of basis set on the second hyperpolarizability has been studied at the CCSD level which showed that Sadlej’s pol and 6-311++G(3df,3pd) basis sets give comparable results that are obtained for the aug-cc-pVTZ basis set. The results of second hyperpolarizability calculated by using different OFT functionals are found to be consistent with the CCSD results obtained for the aug-cc-pVTZ basis set. (C) 2019 Elsevier Inc.

Pyridazine-based heteroleptic copper(II) complexes as potent anticancer drugs by inducing apoptosis and S-phase arrest in breast cancer cell

A new series of heteroleptic copper(II) complexes of the type [Cu(L1-3)(diimine)](ClO4) (1-6) have been synthesized using three pyridazine-based ligands (3-chloro-6-(salicylidenehydrazinyl)pyridazine (HL1), 3-chloro-6-(4-diethylaminosalicylidenehydrazinyl) pyridazine (HL2) and 3-chloro-6-(5-bromosalicylidenehydrazinyl)pyridazine (HL3), and diimine (2,2′-bipyridine (bpy) or 1,10-phenanthroline (phen)) as co-ligands. The ligands and their copper(II) complexes have been characterized by elemental analyses and spectroscopic methods. The copper(II) complexes display ligand-field band in the region 641-661 nm suggesting square pyramidal geometry. The optimized structures of the complexes and their molecular orbital calculations obtained by the density functional theory (DFT) also showed five coordinated distorted square pyramidal geometry around the copper (II) ion. The cyclic voltammetric analyses of copper(II) complexes exhibit one-electron irreversible reduction wave (E-pc = -0.596 to -0.641 V) in the cathodic potential region. Anti-proliferative activity of the complexes against breast cancer MDA-MB-231 cell line was evaluated by MTT cell proliferation assay, and the clonogenic assay revealed improved cytotoxicity for the complexes with potency higher than the standard drug cisplatin. Since the complexes 3 and 4 with diethylamino substituent displayed higher anti-proliferative activity than the other complexes, these complexes were chosen for apoptosis and cell cycle analysis. The apoptosis induction was analyzed by AO/EB staining, and the flow cytometry showed the inhibition of cell growth at the S-phase of the cell cycle. Additionally, the interaction of copper(II) complexes with FGFR kinase receptor have been studied by in silico molecular docking studies.
