Fast and pH-Independent Elimination of trans-Cyclooctene by Using Aminoethyl-Functionalized Tetrazines

The inverse-electron-demand Diels-Alder/pyridazine elimination tandem reaction, in which the allylic substituent on trans-cyclooctene is eliminated following reaction with tetrazines, is gaining interest as a versatile bioorthogonal process. One potential shortcoming of such currently used reactions is their propensity to proceed faster and more efficiently at lower pH, a feature caused by the nature of the tetrazines used. Here, we present aminoethyl-substituted tetrazines as the first pH-independent reagents showing invariably fast elimination kinetics at all biologically relevant pH values.

Synthesis and biological evaluation of 3-O-substituted 1-benzyl-6-oxo-1,6-dihydropyridazine derivatives

On the basis of 2-benzyl-6-hydroxypyridazin-3(2H)-one, a series of its novel O-substituted (including 6-(1,3,5-triazin-2-yl)oxy) derivatives is prepared. It is proven that the substitution reactions in the initial compound occur mainly at the oxygen atom of the hydroxy group. On the basis of the obtained oxy-aceto(propane)hydrazides, the corresponding azides and anilides are synthesized. A series of 2-[(1-benzyl-6-oxo-1,6-dihydropyridazin-3-yl)oxy]-N ‘-(substituted benzylidene)aceto(propane)hydrazides is obtained via the reaction of various aromatic aldehydes with the same hydrazides. Heterocyclization of the latter affords compounds with a combination of pyridazine and 1,3,4-oxadiazole rings in the molecule. The reaction of oxy-acetohydrazide with potassium thiocyanate and a mixture of CS2/KOH leads to potassium salts of 2-{[(1-benzyl-6-oxo-1,6-dihydropyridazin-3-yl)oxy]methyl}hydrazine-1-carbothioamide and 2-{2-[(1-benzyl-6-oxo-1,6-dihydropyridazin-3-yl)oxy]acetyl}hydrazine-1-carbodithioic acid, respectively. Acid hydrolysis of the latter affords 2-benzyl-6-[(5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)methoxy]pyridazin-3(2H)-one.

New bipolar host materials based on methyl substituted pyridazine for high- performance green and red phosphorescent OLEDs

In this work, two host materials, namely DAMP and DCMP were designed and synthesized based on 4,5-dimethylpyridazine and triphenylamine or carbazole. These two compounds exhibit good thermal stability, suitable highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels and balanced carrier transport properties. Green phosphorescent organic light-emitting devices (PhOLEDs) based on DAMP and DCMP exhibit excellent performance with the maximum external quantum efficiencies (EQEs) of 19.5% and 22.2%, respectively. At the luminance of 1000 cd/m(2), the EQE of the device based on DCMP can still reach to 21.4%. Besides, red PhOLEDs hosted by DAMP and DCMP also showed satisfied performance, with the maximum EQE of 15.3% and 20.0%, respectively. These results suggest that DAMP and DCMP are promising host materials for green and red PhOLEDs.

Induction of apoptosis by pyrazolo[3,4-d]pyridazine derivative in lung cancer cells via disruption of Bcl-2/Bax expression balance

In the rapidly expanding era of cancer target therapy, regulators of apoptosis are emerging as attractive therapeutic targets. X-linked inhibitor of apoptosis (XIAP) is of specific interest owing to its characteristic overexpression in a wide variety of neoplasms, with a resultant survival advantage for tumor cells and treatment resistance. In this study, we examined three pyrazolo [3,4-d] pyridazine derivatives (PPDs) through molecular modeling and studied their modes of interaction with XIAP-BIR3 domain. PPD-1, which possessed the highest binding affinity with XIAP, was tested on A549 (lung cancer cell line); HCT-116 (colorectal carcinoma cell line); HEPG2 (liver carcinoma cell line), HFB4 (normal human skin melanocyte cell line) and WI-38 (human embryonic lung fibroblasts). In comparison to cisplatin as a positive control, PPD-1 yielded remarkable cytotoxicity on all cancer cell lines, with the highest anti-tumor activity on A549 and a favorable therapeutic ratio. Flow cytometry studies concluded that PPD-1 treatment induces Sub G1 and G2/M cell cycle arrest and apoptosis. The percentage of apoptotic cells in PPD-1 treated A549 cells was considerably higher than that in untreated cells (10.06% vs 0.57%, respectively). To further investigate the mechanism of induction of apoptosis by PPD-1, Real time-PCR was used to quantify the expression levels of key apoptotic regulators. Significant overexpression of the effector capsase-3, pro-apoptotic bax and tumor suppressor gene p53 were noted as compared to untreated cells (7.19 folds, 7.28 folds, and 5.08 folds, respectively). Moreover, PPD-1 inhibited the expression of the antiapoptotic bcl-2 gene to 0.22 folds. These findings demonstrate that PPD-1 treatment disrupts the Bcl-2/BAX balance in lung cancer cell lines, leading to apoptosis induction possibly through intrinsic mitochondria- dependent pathway. These novel insights elucidate the mechanism of PPD-1 cytotoxicity in lung cancer cell lines and offer a promising therapeutic approach that needs further study. (C) 2017 Elsevier Ltd.

Preparation of an oxetan-phenyltetrahydropyridazine-3,6-dione derivative using some chemistry tools

The aim of this study was to synthesize a new oxetan-phenyltetrahydropyridazine-3,6-dione derivative (compound 6) using different techniques. The first method was achieved by the preparation of a phenylhydrazine derivative (2) using three-components system (3,17-aldol-estradiol, phenylhydrazine, 5-hexyn-3-ol) in the presence of Copper(II). Then, 2 was reacted with tert-butyldimethylsilyl chloride to form the compound 3 (trimethylbutan-silyloxy-steroid-hydrazine). Following, a pyridazine derivative (4) was prepared by the reaction of 3 with succinic acid using boric as catalyst. The compound 4 was reacted with hydrofluoric acid to form the tetrahydropyridazine-3,6-dione (5). Finally, the preparation of 6 was carried out by the reaction of 5 with CopperII. Spectroscopy analyses NMR was used to confirm the chemical structure of compounds. In conclusion, a facile method to synthesize an oxetan-phenyltetrahydropyridazine-3,6-dione is reported.

3,6-Di(pyridin-2-yl) pyridazine derivatives as original and new corrosion inhibitors in support of mild steel: Experimental studies and DFT investigational

Corrosion inhibition performance of three new synthesized novel compounds namely, 1-((3,6-di(pyridin-2-yl) pyrdazin-4-yl)methyl)-indoline-2,3-dione (FM1), 4-(morpholinomethyl)-3,6di( pyridin-2-yl) pyridazine (FM2) and 3,6-di(pyridin-2-yl)-4-(p-tolyl)-pyridazine (FM3) on mild steel (MS) was investigated by HCl with 1 M concentration. The corrosion inhibition performance of the synthesized compounds was studied by weight l.ss, impedance spectroscopy(EIS) and potentiodynamic polarization (PDP) methods. The results showed that the corrosion inhibition efficiency increases with the increase in the concentration of the compounds (FMs). The PDP measurements reveal that the type of these compounds is a mixed-type behavior. The results of impedance studies (EIS) showed that in the presence of FMs, the Rct values increase while the Cdl values decrease due to the adsorption of inhibitors (FMs) on the mild steel surface. EIS study showed that there is one capacitance loop related to charge transfer mechanism. The adsorption of (FMs) on the mild steel surface obeys the Langmuir-adsorption is.therm. The 1-((3,6-di(pyridin-2-yl) pyrdazin-4-yl) methyl)-indoline2,3- dione (FM1) showed a better inhibition performance in comparison with the FM2 and FM3. The theoretical results which shows also a good correlation with the electrochemical experiments and weight loss measurements.
