In our endeavor towards the development of effective VEGFR-2 inhibitors, three novel series of phthalazine derivatives based on 1-piperazinyl-4-arylphthalazine scaffold were synthesized. All the newly prepared phthalazines 16a-k, 18a-e and 21a-g were evaluated in vitro for their inhibitory activity against VEGFR-2. In particular, compounds 16k and 21d potently inhibited VEGFR-2 at sub-micromolar IC50 values 0.35 +/- 0.03 and 0.40 +/- 0.04 mu M, respectively. Moreover, seventeen selected compounds 16c-e, 16g, 16h, 16j, 16k, 18c-e and 21a-g were evaluated for their in vitro anticancer activity according to US-NCI protocol, where compounds 16k and 21d proved to be the most potent anticancer agents. While, compound 16k exhibited potent broad spectrum anticancer activity with full panel GI(50) (MG-MID) value of 3.62 mu M, compound 21d showed high selectivity toward leukemia and prostate cancer subpanels [subpanel GI(50) (MG-MID) 3.51 and 5.15 mu M, respectively]. Molecular docking of compounds16k and 21d into VEGFR-2 active site was performed to explore their potential binding mode. (C) 2015 Elsevier Masson SAS. All rights reserved.

Synthetic Route of 54381-16-7, While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 54381-16-7, Name is 2,2′-((4-Aminophenyl)azanediyl)diethanol sulfate, SMILES is NC1=CC=C(N(CCO)CCO)C=C1.O=S(O)(O)=O, belongs to phthalazine compound. In a article, author is Savjani, Nicky, introduce new discover of the category.

The new bis(iminopyridyl)phthalazine ligand, 1,4-{(2,6-i-Pr2C6H3)N=CMe)C5H3N}(2)C8H4N2 (L), has been prepared in good yield using a combination of palladium-mediated cross coupling and condensation strategies. Reaction of L with three equivalents of CoX2 (X = Cl, Br) in n-BuOH at elevated temperature generates, on crystallisation from bench acetonitrile, the paramagnetic tetrahalocobaltate salts [(L) Co2X(mu-X)(NCMe)(m)(OH2)(n)](CoX4) (X = Cl, m = 2, n = 1 1a; X = Br, m = 2, n = 0 1b) as acetonitrile or mixed acetonitrile/aqua adducts; a similar product is obtained from the reaction of FeCl2 with L and has been tentatively assigned as [(L)Fe2Cl(mu-Cl)(OH2)(3)](FeCl4) (2). By contrast, reaction of L with NiX2(DME) (X = Cl, Br; DME = 1,2-dimethoxyethane), under similar reaction conditions, affords the halide salts [(L) Ni2X2(mu-X)(OH2)(2)](X) (X = Cl 3a, X = Br 3b) as aqua adducts. Structural determinations on 1 and 3 reveal L to adopt a bis(tridentate) bonding mode allowing the halide-bridged metal centres to assemble in close proximity (M center dot center dot center dot M range: 3.437-3.596 angstrom). Unexpectedly, on reaction of L with ZnCl2, the neutral bimetallic [(L) Zn2Cl4] (4b) complex is formed in which the ZnCl2 units fill inequivalent binding sites within L (viz. the N-phth,N-py,N-im and N-py,N-im pockets). Complex 4b could also be obtained by the sequential addition of ZnCl2 to L to form firstly monometallic [(L) ZnCl2] (4a) and then on further ZnCl2 addition 4b; the fluxional behaviour of diamagnetic 4a and 4b is also reported. On activation with excess methylaluminoxane (MAO), 1-3 display modest activities for ethylene oligomerisation forming low molecular weight waxes with methyl-branched products predominating for the nickel systems (3). On the other hand, the iron catalyst (2) gives exclusively alpha-olefins while the cobalt systems (1) are much less selective affording equal mixtures of alpha-olefins and internal olefins along with lower levels of vinylidenes and tri-substituted alkenes. Single crystal X-ray structures are reported for L, 1a, 1b, 3a, 3b and 4. (C) 2015 Elsevier B.V. All rights reserved.

A probe mediated SERS-based strategy is developed to selectively detect hydrazine with superb sensitivity. Ortho-phthaldialdehyde, a simple probe, reacts specifically with hydrazine to form phthalazine, a molecule that possesses a larger Raman cross section and better affinity toward the SERS substrate. We observed a limit of detection of 8.5 X 10(-11) M. Our method shows both qualitative and quantitative measurement of hydrazine with high sensitivity, low cost, and fast analysis time.

The geometry, electronic structure, natural bond orbitals (NBO) and molecular electrostatic potential (MEP) surface analysis were carried out for some bis 1H-Indazolo [1,2-b]phthalazine-triones using HF/3-21G computational method. The theoretical studies revealed the existense of intramoleculare hydrogen bonds and high HOMO-LUMO energy gap for the products structures. Some advantages of this protocol are high yields, short reaction times, simple purification, and environmentally mild reaction conditions.

In a document, author is Akabane, Takafumi.

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.

In continuation of our endeavor with respect to the development of potent and effective isatin-based anticancer agents, we adopted the molecular hybridization approach to design and synthesize four different sets of isatin-quinazoline (6a-f and 7a-e)/phthalazine (8a-f)/quinoxaline (9a-f) hybrids. The antiproliferative activity of the target hybrids was assessed towards HT-29 (colon), ZR-75 (breast) and A-549 (lung) human cancer cell lines. Hybrids 8b-d emerged as the most active antiproliferative congener in this study. Compound 8c induced apoptosis via increasing caspase 3/7 activity by about 5-fold in the A-549 human cancer cell line. In addition, it exhibited an increase in the G1 phase and a decrease in the S and G2/M phases in the cell cycle effect assay. Furthermore, it displayed an inhibitory concentration 50% value of 9.5 mu M against multidrug-resistant NCI-H69AR lung cancer cell line. The hybrid 8c was also subjected to in vitro metabolic investigations through its incubation with rat liver microsomes and analysis of the resulting metabolites with the aid of liquid chromatography-mass spectrometry.
