In a patnet, author is Seo, Dong Wan, once mentioned the new application about 775-12-2.

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).

We have studied the catalytic ability of copper(II) acetate monohydrate as a mild, environmentally benign, natural and economical catalyst for the multi-component efficient synthesis of biologically active spiro-4H-pyran derivatives and 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives with excellent yields and short reaction times. The most important advantages of this procedure are its mild, non-toxic and inexpensive catalyst, one-pot synthesis, environmentally benign nature, solvent-free conditions, simple operational procedures, and highly efficient conditions.

The regio- and chemo-selective Pd-catalyzed C-H activation methods have been successfully reported for directed C-H sulfonation and halogenation of pyridazinedione with arylsulfonyl chlorides and N-halosuccinimide, respectively. These protocols are compatible with a range of various functional groups and exhibit excellent regio-selectivity under mild reaction conditions by use of inexpensive and readily accessible reagents.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 775-12-2, Name is Diphenylsilane, molecular formula is C12H12Si. In an article, author is Jalili-Baleh, Leili,once mentioned of 775-12-2, SDS of cas: 775-12-2.

A novel series of tacrine-like compounds 7a-u possessing a fused pyrazolo[1,2-b]phthalazine structure were designed and synthesized as potent and selective inhibitors of AChE. The in-vitro biological assessments demonstrated that several compounds had high anti-AChE activity at nano-molar level. The more promising compound 71 with IC50 of 49 nM was 7-fold more potent than tacrine and unlike tacrine, it was highly selective against AChE over BuChE. The cell-based assays against hepatocytes (HepG2) and neuronal cell line (PC12) revealed that 71 had significantly lower hepatotoxicity compared to tacrine, with additional neuroprotective activity against H2O2-induced damage in PC12 cells. This compound could also inhibit AChE-induced and self-induced A beta peptide aggregation. The advantages including synthetic accessibility, high potency and selectivity, low toxicity, adjunctive neuroprotective and A beta aggregation inhibitory activity, make this compound as a new multifunctional lead for Alzheimer’s disease drug discovery.

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.
