In a document, author is Seo, Dong Wan.

Phosphoric acid-doped sulfonated poly(tetra phenyl phthalazine ether sulfone) (PA-SPTPPES) copolymers were successfully synthesized by the 4,4′-dihydroxydiphenylsulfone with 1,2-bis(4-fluorobenzoyl)-3,4,5,6-tetraphenylbenzene (BFBTPB) and 4,4′-difluorodiphenylsulfone in sulfolane. Poly(tetra phenyl phthalazine ether sulfone)s (PTPPESs) were prepared via an intramolecular ring-closure reaction of dibenzoylbenzene of precursor and hydrazine. The sulfonated poly(tetra phenyl phthalazine ether sulfone) (SPTPPES) membranes were obtained by sulfonation under concentrated sulfuric acid, and followed phosphoric acid-doped by immersion in phosphoric acid. Different contents of doped and sulfonated unit of PA-SPTPPES (10, 15, 20 mol% of BFBTPB) were studied by FT-IR, H-1 NMR spectroscopy, and thermo gravimetric analysis (TGA). The ion exchange capacity (IEC) and proton conductivity of SPTPPESs and PA-SPTPPESs were evaluated with increase of degree of sulfonation and doping level. The PA-SPTPPESs membranes exhibit proton conductivities (80 degrees C, relative humidity 30%) of 41.3 similar to 74.1 mS/cm and the maximum power densities of PA-SPTPPES 10, 15, and 20 were about 294, 350, and 403 mW/cm(2).

In the current study, two 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 evaluated for their anticancer activities and DNA/purine nucleotide binding properties. These Pt (II) complexes, with the non-classical structures, demonstrated a significant anticancer activity against Jurkat and MCF-7 cancer cell lines. The results of ethidium bromide/acridine orange staining and Caspase-III activity suggest that these complexes were capable to stimulate an apoptotic mechanism of cell death in the cancer cells. Using different biophysical techniques and docking simulation analysis, we indicated that these complexes were also capable to interact efficiently with DNA via a non-intercalative mechanism. According to our results, substitution of cyclopentane (in complex 2) with two methyl groups (in complex 1) results in significant improvement of the complex ability to interact with DNA and subsequently to induce the anticancer activity. Overall, these binuclear Pt (II) complexes are promising group of the non-classical potential anticancer agents which can be considered as molecular templates in designing of highly efficient platinum anticancer drugs.

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.

In an article, author is Sanchez-Moreno, Manuel, once mentioned the application of 24324-17-2, Quality Control of 9-Fluorenemethanol, Name is 9-Fluorenemethanol, molecular formula is C14H12O, molecular weight is 196.2445, MDL number is MFCD00001139, category is phthalazine. Now introduce a scientific discovery about this category.

Objectives: To evaluate the in vitro leishmanicidal activity of imidazole-based (1-4) and pyrazole-based (5-6) benzo[g] phthalazine derivatives against Leishmania infantum and Leishmania braziliensis. Methods: The in vitro activity of compounds 1-6 was assayed on extracellular promastigote and axenic amastigote forms, and on intracellular amastigote forms of the parasites. Infectivity and cytotoxicity tests were performed on J774.2 macrophage cells using meglumine antimoniate (Glucantime) as the reference drug. The mechanisms of action were analysed by iron superoxide dismutase (Fe-SOD) and copper/zinc superoxide dismutase (CuZn-SOD) inhibition, metabolite excretion and transmission electronic microscopy (TEM). Results: Compounds 1-6 were more active and less toxic than meglumine antimoniate. Data on infection rates and amastigote mean numbers showed that 2, 4 and 6 were more active than 1, 3 and 5 in both L. infantum and L. braziliensis. The inhibitory effect of these compounds on the antioxidant enzyme Fe-SOD of promastigote forms of the parasites was remarkable, whereas inhibition of human CuZn-SOD was negligible. The ultrastructural alterations observed in treated promastigote forms confirmed the greater cell damage caused by the most active compounds 2, 4 and 6. The modifications observed by 1H-NMR in the nature and amounts of catabolites excreted by the parasites after treatment with 1-6 suggested that the catabolic mechanisms could depend on the structure of the side chains linked to the benzo[g] phthalazine moiety. Conclusions: All the compounds assayed were active in vitro against the two Leishmania species and were less toxic against mammalian cells than the reference drug, but the monosubstituted compounds were significantly more effective and less toxic than their disubstituted counterparts.

A novel Bronsted acidic ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate [Simp]HSO4 was synthesized via the reaction of caffeine with chlorosulfonic acid and was characterized by studying FT-IR, H-1 NMR, C-13 NMR, UV-Vis, and fluorescence spectra. Then, the prepared ionic liquid was utilized as an efficient catalyst for the preparation of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives through one-pot, multi-component condensation of aldehydes, phthalhydrazide, and dimedone under solvent free conditions. The high Bronsted acidic function of this catalyst originates principally from the dual hydrogen bonding abilities of the SO3H group. (C) 2015 Elsevier B.V. All rights reserved.
