In a document, author is Shahsavani, Mohammad Bagher, introduce the new discover.

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.

In this research, an efficient procedure for the one-pot four-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones catalyzed by a cobalt-based nanocatalyst (Co/Al2O3 nanocatalyst) is reported. The catalyst was prepared by a co-precipitation method and characterized by BET surface area, SEM, TEM, EDS and XRD analyses. A wide range of various aromatic aldehydes including electron-withdrawing and electron-releasing groups were applied and corresponding products obtained in high yields without any by-product. Moreover, the Co/Al2O3 is recyclable up to 7 consecutive runs by simple filtration.

In an article, author is Patil, Audumbar, once mentioned the application of 3648-20-2, Name is Diundecyl phthalate, molecular formula is C30H50O4, molecular weight is 474.7156, MDL number is MFCD00043729, category is phthalazine. Now introduce a scientific discovery about this category, Related Products of 3648-20-2.

The volatile, harmful and hazardous solvents have impact on human health, all organisms and environment. To reduce the use of hazardous volatile solvents, there is need to develop the alternative green reaction medium for organic transformations and is the main goal of green chemistry. The green solvent should be nonvolatile, nontoxic, biodegradable and biorenewable. Considering these parameters, herein, we have reported an efficient and environmentally benign green synthesis of chromeno pyrazolo and indazolo phthalazine derivatives in deep eutectic solvent. The present protocol contains excellent yield of the product, short reaction time, operation simplicity, reusability of solvent and no need of further purification.

In a document, author is Wasfy, Ashraf Farouq, introduce the new discover.

Phthalazine derivatives attached to amino acid derivatives were synthesized with high yields. The reaction of phthalazine derivatives with different phthalyl and tosylamino acids such as glycine, alanine, phenylalanine, valine, serine, and threonine in the presence of N,N-dicyclo hexylcarbodiimide (DCC) as a dehydrating agent reagent yielded high yields of the afforded compounds. Phthalylamino acids derivatives were obtained by deprotection of phthalazine derivatives, with the latter heating with hydrazine hydrate. The chemical structures of all phthalazine derivatives were affirmed by elemental analysis and spectral data (IR, MS, (HNMR)-H-1, and C-13 NMR). Screening out and estimation of the synthesized derivatives for their cytotoxic and antioxidant activity were done, and most of them showed powerful activity in comparison with standard drugs.

The paper presents a combined experimental and computational study for three oxalate copper(II) complexes [Cu(ptz)(2)(C2O4)(H2O)center dot 1.5H(2)O (1), [Cu(dppt)(C2O4)(H2O)]center dot H2O.MeOH (2) and [Cu(dmdpq)(C2O4)(- H2O)]center dot 5H(2)O (3) (ptz = phthalazine, dppt = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine and dmdpq = 6,7-dimethyl-2,3-di(2-pyridyl)quinoxaline). The compounds have been studied by IR, UV-Vis spectroscopy and single crystal X-ray analysis. Due to the presence of coordinated water molecules and oxalate groups together with the lattice solvent molecules (water and methanol) their crystal structures are dominated by the hydrogen-bonding interactions that give rise to the supramolecular architectures. To elucidate the structural and spectroscopic properties of[Cu(ptz)(2)(C2O4)(H2O)], [Cu(dppt)(C2O4)(H2O)] and [Cu(dmdpq)(C2O4)(H2O)], calculations at DFT, TDDFT level were undertaken. Magnetic studies of all complexes under study showed paramagnetic behavior with large orbital magnetic contribution. (c) 2013 Elsevier Ltd. All rights reserved.

The aluminum(I) compound NacNacAl (NacNac=[ArNC(Me)CHC(Me)NAr](-), Ar=2,6-iPr(2)C(6)H(3),1) shows diverse and substrate-controlled reactivity in reactions with N-heterocycles. 4-Dimethylaminopyridine (DMAP), a basic substrate in which the 4-position is blocked, induces rearrangement of NacNacAl by shifting a hydrogen atom from the methyl group of the NacNac backbone to the aluminum center. In contrast, C-H activation of the methyl group of 4-picoline takes place to produce a species with a reactive terminal methylene. Reaction of1with 3,5-lutidine results in the first example of an uncatalyzed, room-temperature cleavage of an sp(2)C-H bond (in the 4-position) by an Al(I)species. Another reactivity mode was observed for quinoline, which undergoes 2,2 ‘-coupling. Finally, the reaction of1with phthalazine produces the product of N-N bond cleavage.
