An eco-friendly and efficient green protocol is developed for the synthesis of sixteen pyrazolo-phthalazine derivatives (5a-p) by using inexpensive biodegradable eggshell powder (ESP) as a heterogeneous catalyst. The four-component one-pot condensation reaction proceeded through Knoevenagel-Michael reaction of different chosen active methylene compounds, phthalic anhydride, and hydrazine hydride with various substituted aromatic aldehydes in the water at 60 degrees C, and furnished the high yields of products (93-98%) in rapid reaction time of 28 to 45 min. The material was characterized by different analytical techniques (SEM, TEM, XRD, BET, and FT-IR), and was composed of the high percentage of calcium oxides and carbonates, and less percentage of Na and Mg elements (based on EDX analysis). The ESP material displayed recyclability (4 times) without any notable loss of catalytic efficacy. Besides, this procedure offers 98% of the atom economy and 100% of carbon efficiency together with significant fiscal and enviro-friendly benefits.

Synthesis, structural and biological studies of two new Co(III) complexes with tridentate hydrazone ligand derived from the antihypertensive drug hydralazine

A new Schiff base derived from the antihypertensive hydralazine (LH) and its Co(III) complexes [CoL2] X*4H(2)O, where X = NO3 (1) or Cl (2), were synthesized and characterized using FTIR, UV-Vis,H-1 NMR spectroscopy as well as thermal analysis. The crystal structures of the three compounds have been determined using single crystal X-ray diffraction technique. The two complexes structure is strictly divided in a highly ordered part of the [CoL2](+) units and a disordered section containing the anions and sixteen crystal water molecules per unit cell. In the complexes, the two ligand anions (L-) chelate to the Co(III) through the nitrogen atoms in a tridentate meridional manner. The pyridine and phthalazine rings showed deviations from co-planarity in all compounds which attributed to the crystal packing effects as revealed by analysis of their molecular packing using Hirshfeld analysis and further supported by DFT calculations. The optimized structure of the [CoL2] NO3 as a model showed no co-planarity of the two rings while perfectly planar ligand units were predicted in the [CoL2](+) cation indicating that the intermolecular interactions with the nitrate counter anion have a major role in the deviations of the two ring moieties from planarity. The ligand anion (L-) optimized structure using B97D function which include dispersion model showed similar results while the functions (B3LYP and mPW1PW91) which include no dispersion model predicted perfectly planar arrangement. Atoms in molecules (AIM) studies predicted the strength of the Co-N interactions is in the order, Co-N(azomethine) > Co-N(phthalazine) > Co-N(pyridine) which are generally stronger in 2 than 1. The developmental toxicity of LH and its complexes were tested in zebrafish embryos. The ligand itself was very toxic with LC50 of just 2 mu M as compared to its metal complexes, whereas, at sub-lethal concentration the ligand perturbed the neurogenesis in zebrafish embryos.

Evidence for Substrate-Dependent Inhibition Profiles for Human Liver Aldehyde Oxidase

The goal of this study was to provide a reasonable assessment of how probe substrate selection may impact the results of in vitro aldehyde oxidase (AO) inhibition experiments. Here, we used a previously studied set of seven known AO inhibitors to probe the inhibition profile of a pharmacologically relevant substrate N-[(2-dimethylamino)ethyl]acridine-4-carboxamide (DACA). DACA oxidation in human liver cytosol was characterized with a measured V-max of 2.3 +/- 0.08 nmol product . min(-1) . mg(-1) and a K-m of 6.3 +/- 6 0.8 mu M. The K-ii and K-is values describing the inhibition of DACA oxidation by the panel of seven inhibitors were tabulated and compared with previous findings with phthalazine as the substrate. In every case, the inhibition profile shifted to a much less uncompetitive mode of inhibition for DACA relative to phthalazine. With the exception of one inhibitor, raloxifene, this change in inhibition profile seems to be a result of a decrease in the uncompetitive mode of inhibition (an affected K-ii value), whereas the competitive mode (K-is) seems to be relatively consistent between substrates. Raloxifene was found to inhibit competitively when using DACA as a probe, and a previous report showed that raloxifene inhibited uncompetitively with other substrates. The relevance of these data to the mechanistic understanding of aldehyde oxidase inhibition and potential implications on drug-drug interactions is discussed. Overall, it appears that the choice in substrate may be critical when conducting mechanistic inhibition or in vitro drug-drug interactions prediction studies with AO

Synthesis and evaluation of novel dimethylpyridazine derivatives as hedgehog signaling pathway inhibitors

We report herein the design and synthesis of a series of structural modified dimethylpyridazine compounds as novel hedgehog signaling pathway inhibitors. The bicyclic phthalazine core and 4-methylamino- piperidine moiety of Taladegib were replaced with dimethylpyridazine and different azacycle building blocks, respectively. The in vitro Gli-luciferase assay results demonstrate that the new scaffold still retained potent inhibitory potency. Piperidin-4-amine moiety was found to be the best linker between pharmacophores dimethylpyridazine and fluorine substituted benzoyl group. Furthermore, the optimization of 1-methyl-1H-pyrazol and 4-fluoro-2-(trifluoromethyl) benzamide by different aliphatic or aromatic rings were also investigated and the SAR were described. Several new derivatives were found to show potent Hh signaling inhibitory activity with nanomolar IC50 values. Among these compounds, compound 11c showed the highest inhibitory potency with an IC50 value of 2.33 nM, which was comparable to the lead compound Taladegib. In vivo efficacy of 11c in a ptch(+/)-p53(-/-) mouse medulloblastoma allograft model also indicated encouraging results. (C) 2018 Elsevier Ltd. All rights reserved.

Preparation of a poly(phthalazine ether sulfone ketone) membrane with propanedioic acid as an additive and the prediction of its structure

In this study, propanedioic acid was investigated as a potential additive in poly(phthalazine ether sulfone ketone) (PPESK)/N-methyl-2-pyrrolidone solutions. Compared with poly(ethylene glycol) with a molecular weight of 1000 and Tween 80 as additives, different phenomena were observed: (1) both fingerlike and spongelike structures of asymmetric ultrafiltration membranes were induced by rapid gelation, and (2) a spongelike structure membrane with a high pure water flux was obtained under a high gelation rate. Moreover, the PPESK membrane formation process was recorded with a recently developed optical microscopy (OM)-charge-coupled device (CCD) camera experimental system. The predicted membrane structure with an OM-CCD system gave good correspondence with the final membrane structure and performance, as detected by scanning electron microscopy.

Electrocatalytic multicomponent assembling of phthalhydrazide, aldehydes and malononitrile: An efficient approach to 1H-pyrazolo[1,2-b]phthalazine-5,10-diones

Electrocatalytic multicomponent transformation of phthalhydrazide, aromatic aldehydes and malononitrile in n-propanol in an undivided cell in the presence of sodium bromide as an electrolyte leads to 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in short reaction times (4-8 min) and high yields (85-98%) at room temperature. The developed efficient electrocatalytic approach to the corresponding 1H-pyrazolo[1,2-b]phthalazine-5,10-diones is beneficial from the viewpoint of diversity-oriented large-scale processes and represents a new example of the ecologically pure synthetic concept for electrocatalytic multicomponent reactions strategy.

Electro-Organic Synthesis: An Efficient Method for the Preparation of Nanosized Particles of Phthalazine Derivatives via One-Pot Multicomponent Reactions

Aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. This contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. The method is based on the one-pot multicomponent reaction (MCRs) of phthalhydrazide, malononitrile and aldehydes in propanol employing undivided cell in the presence of NaBr as an electrolyte. The product was characterized, after purification, using IR, (HNMR)-H-1, C-13 NMR, MS and SEM. This procedure provides a method by which nanoparticles are synthesized directly from phthalhydrazide, malononitrile and aldehydes insides of a routine protocol for the synthesis of nano particles of organic compounds in which the synthesized organic compound is transformed into nanosized particles using modem high technology, for example ultrahighpressure rapid expansion of supercritical solution, and supercritical antisolvent with enhanced mass transfer. Size reduction is a fundamental unit operation having important applications in pharmacy. It helps to improve solubility and bioavailability, reduce toxicity, enhance release, and provide better formulation opportunities for drugs.
