Oxidative ring cleavage of 2,3-dihydrophthalazine-1,4-dione in aqueous and non-aqueous solutions: Electrochemical and kinetic studies

Electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (DHP) has been investigated in aqueous and some amphiprotic and aprotic non-aqueous solvents by cyclic voltammetric and controlled-potential coulometric techniques. Our data shows that electrochemically generated phthalazine-1,4-dione (PTD) in water and amphiprotic non-aqueous solvents participates in an oxidative ring cleavage (ORC) reaction to form phthalic acid. The rate of this reaction is dependent. On autoprotolysis constant (K-SH) and basicity of the solvent. Therefore, in the aprotic non-aqueous solvents such as acetonitrile and DMSO, the rate of ORC is too slow to be observed on the time-scale of cyclic voltammetry.

1,3-Diylideneisoindolines: Synthesis, Structure, Redox, and Optical Properties

Diiminoisoindoline (DII) is a crucial reagent for the synthesis of phthalocyanine as well as related macrocycles and chelates such as hemiporphyrazine and bis(iminopyridyl)isoindoline. In this report, we present the synthesis and characterization of four 1,3-diylideneisoindolines prepared via the reaction of several organic CH acids and DII. These orange or red compounds exhibit intense pi-pi* transitions in the UV visible region. The redox properties and electronic structures of all new compounds were investigated using cyclic voltammetry and density functional theory (DFT). The observed electrochemistry and UV-visible transitions are in good agreement with the DFT and time-dependent DFT calculations, which indicate that the HOMO is largely centered at the O=C-C-C=O fragments, and the lowest unoccupied molecular orbital is more extended onto the isoindoline unit.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 122-99-6. The above is the message from the blog manager. Product Details of 122-99-6.

A facile electrochemical method for the synthesis of new sulfonamide derivatives of potential biological significance

The electrochemical synthesis of some new sulfonamide derivatives was carried out via the electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (1) in the presence of arylsulfinic acids (2a and 2b) as nucleophiles. The results show that, the electrogenerated phthalazine-1,4-dione (1ox) participates in a Michael type addition reaction with 2a or 2b and via an EC mechanism to produce the corresponding sulfonamide derivatives. This method provides a one-pot procedure for the synthesis of new sulfonamide derivatives of potential biological significance in good yields without using toxic reagents at a carbon electrode in an environmentally friendly manner.

ONE-POT FOUR COMPONENT REACTION FOR THE SYNTHESIS OF 1-(1H-INDOL-2-YL)-1H-PYRAZOLO [1,2-b]PHTHALAZINE-5,10-DIONE DERIVATIVES BY SELF-CATALYSIS

In this, we performed a four component domino reaction of phthaloyl dichloride, hydrazine hydrate, indole-3-carboxaldehydes and malononitrile/ethyl cyanoacetate to form 1-(1H-indol-2-yl)-1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by in situ generation of HCl as catalyst in refluxing ethanol for 1 h in good yields. This four component domino reaction transformation presumably proceeds via addition/dehydrohalogenation/condensation/cyclization of reactions. The material was thoroughly characterized at various stages of its formation by means of FTIR, NMR spectroscopic and Mass spectrometric analysis and is confirmed to be the derivative of 1-(1H-indo1-2-yl)-1H-pyrazolo [1,2-b]phthalazine-5,10-dione.

Asymmetric Boron-Cored Aggregation-Induced Emission Luminogen with Multiple Functions Synthesized through Stepwise Conversion from a Symmetric Ligand

Multifunction luminogens have emerged as promising candidates in high-performance sensor and imaging systems. Concise approaches to the synthesis of such molecules are urgently required both for fundamental research and technological applications. In this study, a new symmetric ligand of di(2-hydroxyphenyl)phthalazine with multiple binding sites around a phthalazine unit was readily synthesized, which could be converted efficiently into an asymmetric luminogen (OBNDHPP) through the formation of oxygen-boron-nitrogen bonding. This molecule has a twistable it-extended backbone with a tetracoordinated boron core bearing two bulky phenyl groups, giving it abundant optical properties including a large Stokes shift piezochromism and aggregationinduced emission enhancement. Importantly, the presence of a free phenolic hydroxyl group in the backbone of OBN-DHPP enables the incorporation of various functional moieties into the asymmetric luminogen. As an example, polyethylene glycol (PEG)-modified luminogen (OBN-DHPP-PEG(45)) was synthesized. In the aqueous medium, OBN-DHPP-PEG(45) could self-assemble into spherical nanoparticles with low cytotoxicity and excellent emission performance as well as high solubility. The results of flow cytometry and fluorescence microscopy reveal that these nanoparticles could be internalized successfully by HeLa cells, demonstrating their potential application in bioimaging.

Herein we report the design and synthesis of a new series of phthalazine derivatives as Topo II inhibitors and DNA intercalators. The synthesized compounds were in vitro evaluated for their cytotoxic activities against HepG-2, MCF-7 and HCT-116 cell lines. Additionally, Topo II inhibitory activity and DNA intercalating affinity were investigated for the most active compounds as a potential mechanism for the anticancer activity. Compounds 15h, 23c, 32a, 32b, and 33 exhibited the highest activities against Topo II with IC50, ranging from 5.44 to 8.90 mu M, while compounds 27 and 32a were found to be the most potent DNA binders at IC50, values of 36.02 and 48.30 mu M, respectively. Moreover, compound 32a induced apoptosis in HepG-2 cells and arrested the cell cycle at the G2/M phase. Besides, compound 32a showed Topo II poisoning effect at concentrations of 2.5 and 5 mu M, and Topo II catalytic inhibitory effect at a concentration of 10 mu M. In addition, compound 32b showed in vivo a significant tumor growth inhibition effect. Furthermore, molecular docking studies were carried out against DNA-Topo II complex and DNA to investigate the binding patterns of the designed compounds.

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.
