A novel three-step entry toward phthalazine derivatives has been elaborated. A strategy based on a sequential acyl-alkylation/diazo transfer reaction/Diaza-Wittig reaction led to the desired analogues in moderate to good yields from an aryne precursor. Various aryl groups were introduced on the annulated pyridazine, moreover the presence of an ester group allows further modifications. (C) 2013 Elsevier Ltd. All rights reserved.

Some new derivatives of 3-amino-1-aryl-N-butyl-5,10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b]- phthalazine-2-carboxamide are synthesized via in situ Knoevenagel condensation of aromatic aldehydes with N-butyl-2-cyanoacetamide, which leads to 3-aryl-N-butyl-2-cyanoacrylamides.

In an article, author is Magyari, Jozef, once mentioned the application of 1149-26-4, Safety of Z-L-Val-OH, Name is Z-L-Val-OH, molecular formula is C13H17NO4, molecular weight is 251.28, MDL number is MFCD00008922, category is phthalazine. Now introduce a scientific discovery about this category.

New coordination compounds have been synthesized by reacting Zn(II) and Co(II) nitrate or acetate in the presence of triethylamine with Schiff-base ligands containing diazine-ring, pyridine-2-carbaldehyde phthalazine-1-hydrazone,HzPYH, and di(2-pyridyl)ketone 3-chloro-pyridazine-6-hydrazone,HpDPKH. Complexes of[Co(HzPY)(2)]center dot 3.4H(2)O,[Zn(HzPY)(2)]and[Co(HpDPK)(2)]NO3 center dot H(2)Owere obtained. The crystal and the molecular structure of[Co(HzPY)(2)]center dot 3.4H(2)Owere determined using X-ray diffraction structure analysis. The compounds were characterized by elemental analysis, FT-IR and UV-Vis spectral data, conductivity and magnetic measurements, too. Except for the diamagnetic Co(III) compound with a nitrate counter-ion,[Co(HpDPK)(2)]NO3 center dot H2O, all the complexes are neutral-type. The magnetic moment of[Co(HzPY)(2)]center dot 3.4H(2)Oindicated a low-spin octahedral complex which is relatively rear amongst octahedral Co(II) complexes. Hence, its magnetic moment was measured in the temperature range of 3-300 K. To obtain products in the form of single crystals and/or to increase the yield, the reactions were carried out in solutions with different solvents or recrystallized from solvent mixtures. To determine the nature of the solvent (if any) in the crystalline products and to gain better insight into the decomposition mechanism, coupled TG-MS measurements were carried out. The desolvated compounds were stable at relatively high temperatures (> 200 degrees C). The cytotoxic, antiproliferative and efflux pump inhibitory effects of the compounds were tested in multidrug-resistant mouse T-lymphoma cells to study their effect on the suppression of MDR. The antibacterial activity of the compounds was also tested. The results of the antibacterial tests were analysed to understand better the effect of the central atoms and the structure on a specific activity.

Human hepatocytes are a physiologically relevant tool useful in evaluating liver-related pharmacokinetics, including non-cytochrome P-450 (CYP) metabolism, due to their broad spectrum of metabolic enzyme activity. To verify the usefulness of human hepatocytes in evaluating non-CYP metabolism for drug discovery, we compared intrinsic clearance values (CLint) in freshly isolated and cryopreserved hepatocytes using 14 compounds primarily metabolized by non-CYP enzymes, including UDP-glucuronosyltransferase, carbonyl/aldo-keto reductase, aldehyde oxidase, flavin-containing monooxygenase, and monoamineoxidase. Cryopreservation resulted in a > 20% reduction (maximum: 50%) in CLint in 7/14 compounds (statistically significant for 5 compounds) on comparing CLint values in freshly isolated and cryopreserved hepatocytes from the same donors (n = 4). However, the number of compounds with > 20% CLint reduction decreased to 3 on comparing average of CLint values including un-matched donors (dolasetron: -27%, naltorexone: -32%, and phthalazine: -48%; statistically significant for phthalazine, n = 6-11). These findings suggest that fresh hepatocytes are useful in evaluating intact non-CYP enzyme activities. However, we must note that the reduction in CLint by cryopreservation could be rendered negligible if high-activity lots are selected for assay. We therefore recommend using cryopreserved hepatocytes for large-scale screening for non-CYP metabolism in drug discovery research considering the advantages in usability with cryopreserved hepatocytes.

Efforts to develop new antitumor agents are now directed towards multitarget therapies that are believed to have high potency and low tendency to resistance compared to conventional drugs. Herein, we highlighted the synthesis and antitumor activity of five series of phthalazine-based compounds featuring a variety of bioactive chemical fragments at position 1 of the phthalazine nucleus. The antitumor activity of the target compounds was performed against fourteen cancer cell lines where all compounds were active in the nanomolar level. In addition, the mechanism of action of the target compounds was investigated through an enzymatic inhibitory assay against VEGFR-2 and EGFR kinases, revealing potent and preferential activity toward VEGFR-2. Binding mode of the most active compounds was studied using docking experiment. (C) 2016 Elsevier Masson SAS. All rights reserved.

An atom-efficient and environmentally friendly approach to the synthesis of 2,5-disubstituted-1,3,4-thidiazine derivatives has been developed. These compounds were synthesized by a reaction of 2-(2-bromoacetyl)benzofuran and thiocarbohydrazide with various aryl aldehydes, acetylacetones, and pthalic anhydrides in good yields. The advantages of this methodology are mild reaction conditions, easy workup procedure, clean reaction profile, shorter reaction time, and a wide range of substrate applicability. The structures of all synthesized compounds were confirmed from their analytical and spectral data.
