In this study, a new and effective catalyst for the synthesis of pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine derivatives was introduced. Triethanolammonium acetate ([TEAH][OAc]) accelerates the reaction in a one-pot and four-component condensation of aldehydes, hydrazine hydrate, succinic/phthalic anhydride, and 1,3-dicarbonyl compounds. The yield of the products is high, and the reaction conditions are mild and solvent-free. Furthermore, the model reaction was conducted in the presence of triethanolammonium sulphate ([TEAH][HSO4] and triethanolammonium formate ([TEAH][HCOO]) under various conditions. In addition, the catalyst is recyclable, therefore, it can be reused several times. The structure of the obtained products was confirmed by comparing the M.P., IR, and H-1 NMR. Advantages of this technique are as following: Synthesis of novel, green, and one-pot and four-component condensation (4CC) under solvent-free conditions at room temperature. The catalytic reaction is performed under mild and environmentally friendly conditions in short reaction times and excellent yields. The catalyst is easily recycled and exhibits good chemical and structural stability. (C) 2020 The Author(s). Published by Elsevier B.V.

As aldehyde oxidase (AOX) plays an emerging role in drug metabolism, understanding its significance for drug-drug interactions (DDI) is important. Therefore, we tested 10 compounds for species-specific and substrate-dependent differences in the inhibitory effect of AOX activity using genetically engineered HEK293 cells over- expressing human AOX1, mouse AOX1 or mouse AOX3 The IC50 values of 10 potential inhibitors of the three AOX enzymes were determined using phthalazine and O-6-benzylguanine as substrates 17 beta-Estradiol, mena dione, norharmane and raloxifene exhibited marked differences in inhibitory effects between the human and mouse AOX isoforms when the phthalazine substrate was used. Some of the compounds tested exhibited substrate dependent differences m their inhibitory effects. Docking simulations with human AOX1 and mouse AOX3 were conducted for six representative inhibitors. The rank order of the minimum binding energy reflected the order of the corresponding IC50 values. We also evaluated the potential DDI between an AOX substrate (O-6-benzylguanine) and an inhibitor (hydralazine) using chimeric mice with humanized livers. Pretreatment of hydralazine increased the maximum plasma concentration (C-max) and the area under the plasma concentration- time curve (AUC(0-24)) of O-6-benzylguanine compared to single administration. Our in vitro data indicate species-specific and substrate-dependent differences in the inhibitory effects on AOX activity. Our in vivo data demon strate the existence of a DDI which may be of relevance in the clinical context.

Development of three ways molecular logic gate based on water soluble phenazine fluorescent ‘selective ion’ sensor

New hydrophilic fluorescent selective ion sensor based on phenazine and phthalazine moieties, 1,1′-(phenazine-2,3-diyl)-bis(3-(1,4-dihydroxyphthalazin-6-yl)urea) (1), has been designed, synthesized and characterized. Interestingly, sensor 1 exhibits prominent turn-on and turn-off’ fluorogenic signaling at 580 nm towards Fe2+ & AcO- and Sr2+ & Cu2+, respectively. The fluorescence titration experiments shed light on the nature of the interaction between 1 and guest molecules (Fe2+, Sr2+, Cu2+ and AcO-), which divulge that 1 is flexible enough to orient itself according to the size of the guest molecule. Water mediated excited-state intramolecular proton transfer (ESIPT) and photo-induced electron transfer (PET) mechanisms are responsible for the dual behavior of 1, which binds with guest molecules in 1:1 stoichiometry, Based on the significant duplex fluorescence response of 1, a molecular logic gate keypad lock with sixteen on passwords for a storage system has been developed.

Comparative study on the interaction of two binuclear Pt (II) complexes with human serum albumin: Spectroscopic and docking simulation assessments

Human serum albumin (HSA) principally tasks as a transport carrier for a vast variety of natural compounds and pharmaceutical drugs. In the present study, two structurally related binuclear Pt (II) complexes containing cis, cis-[Me2Pt (mu-NN) (mu-dppm) PtMe2] (1), and cis, cis-[Me2Pt(mu-NN)(mu dppm) Pt((CH2)(4))] (2) in which NN = phthalazine and dppm = bis (diphenylphosphino) methane were used to investigate their interaction with HSA, using UV Vis absorption spectroscopy, fluorescence, circular dichroism and molecular dynamic analyses. The spectroscopic results suggest that upon binding to HSA, the binuclear Pt (II) complexes could effectively induce structural alteration of this protein. These complexes can bind to HSA with the binding affinities of the following order: complex 2 > complex 1. Moreover, the thermodynamic parameters of binding between these complexes and HSA suggested the existence of entropy-driven spontaneous interaction, which mostly dominated with the hydrophobic forces. The ANS fluorescence results also indicated that two binuclear Pt (II) complexes were competing for the binding to the hydrophobic regions on HSA. In addition, competitive displacement assay and docking simulation study revealed that complexes 1 and 2 bind to the drug binding sites II and Ion HSA, respectively. Furthermore, complex 2, with the higher binding affinity for HSA, shows more denaturing effect on this protein. Considering the protein structural damages in the pathway of harmful side effects of platinum drugs, complex 1 with the moderate binding affinity and low denaturing effect might be of high significance.

Phthalazine-trione as a blue-green light-emitting moiety: crystal structures, photoluminescence and theoretical calculations

Phthalazine (2,3-diazanaphthalene) and phthalhydrazide (2,3-dihydro-1,4-phthalazinedione) compounds are heterocycles with several biological properties. Most recently, analogous phthalazine-triones also emerged as drug candidates. Herein, we introduced a phthalazine-trione moiety as a promising fluorophore in the blue and green spectral regions. This desired optical property was rationalized based on their crystal structure and time-dependent density functional theory (TD-DFT) calculations. Under ultraviolet (UV) excitation (ca. 360 nm), two light emission maxima at ca. 460 nm and 480 nm were observed for ten phthalazine-triones, regardless of the substitution pattern. This conservation in the light-emitting property was rationalized by our time-dependent DFT calculations for the three phthalazine-triones whose crystal geometries were also determined in this study (4-chlorophenyl, 3-methoxyphenyl and 4-nitrophenyl derivatives) and for those available in literature (4-fluorophenyl and 4-bromophenyl derivatives). Electronic transitions with the largest oscillator strengths were near 360 nm and were in excellent agreement with the experimental excitation energy (UV-visible and photoluminescence spectra). Lifetime values of selected samples could also be determined, which were between 1.59 ns and 3.21 ns. In all compounds, the Frontier molecular orbitals involved in these excitations were distributed over the phthalazine-trione moiety and were not localized on the changeable substituent.
