Various pyridopyridazinone derivatives were designed as Poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors. The pyridopyridazinone scaffold was used as an isostere of the phthalazine nucleus of the lead compound Olaparib in addition to some modifications in the tail part of the molecule. Preliminary biological evaluation indicated that most compounds possessed inhibitory potencies comparable to Olaparib in nanomolar level. The best PARP-1 inhibitory activity was observed for compound 8a with (IC50 = 36 nM) compared to Olaparib as a reference drug (IC50 = 34 nM). Molecular modeling simulation revealed that, the designed compounds docked well into PARP-1 active site and their complexes are stabilized by three key hydrogen bond interactions with both Gly863 and Ser904 as well as other favorable pi-pi and hydrogen-pi stacking interactions with Tyr907 and Tyr896, respectively. Computational ADME study predicted that the target compounds 8a and 8e have proper pharmacokinetic and drug-likeness properties. These outcomes afford a new structural framework for the design of novel inhibitors for PARP-1.

Aldehyde oxidase (AOX) is a xanthine oxidase (XO)-related enzyme with emerging importance due to its role in the metabolism of drugs and xenobiotics. We report the first crystal structures of human AOX1, substrate free (2.6-angstrom resolution) and in complex with the substrate phthalazine and the inhibitor thioridazine (2.7-angstrom resolution). Analysis of the protein active site combined with steady-state kinetic studies highlight the unique features, including binding and substrate orientation at the active site, that characterize human AOX1 as an important drug-metabolizing enzyme. Structural analysis of the complex with the noncompetitive inhibitor thioridazine revealed a new, unexpected and fully occupied inhibitor-binding site that is structurally conserved among mammalian AOXs and XO. The new structural insights into the catalytic and inhibition mechanisms of human AOX that we now report will be of great value for the rational analysis of clinical drug interactions involving inhibition of AOX1 and for the prediction and design of AOX-stable putative drugs.

This paper reports an evaluation of the effect of both organic and inorganic additives on the gelation kinetics, morphology and separation properties of asymmetric poly(phthalazine ether ketone) (PPEK) hollow fiber ultrafiltration membranes. Using an online optical microscope-CCD camera for observation of precipitation front movement (X), a good linear relationship between X-2 and time was observed for the whole gelation process with the correlation coefficient (R-2) higher than 0.98. It was found that the pure water flux of membranes with additives were lower than neat PPEK membranes. This observation might be attributed to the decrease in the face gelation velocity caused by the extra organic additives. The water flux of PEG600 was higher than that of Tween80 at the same additive concentration. When OA concentration increased from 3.5 to 5.0 wt.%, the pure water flux increased from 332 to 367 L/m(2) hand the rejection decreased from 98.6 to 96.8%. The PPEK hollow fiber membranes exhibited finger-like macrovoids structure and a skin layer at the outer-most region of the hollow fiber. Evaluation of the membrane chemical resistance with various chemical solutions indicated that PPEK membranes had good chemical resistance against HCI, H2SO4, HNO3, CH3COOH, OA, NaOH and H2O2, while the NaClO solution can greatly damage the membrane mechanical strength. Static sorption tests of PPEK membrane revealed that PPEK membrane adsorbed more bacitracin than BSA due to the smaller size of bacitracin. (C) 2011 Elsevier B.V. All rights reserved.

Pathogenic fungi are one of the main causes of hospital-related infections. Since conventional antifungals have become less effective because of the increasing fungal resistance to the standard drugs, the need for new agents is becoming urgent. Herein we report a synthesis of a series of novel N-[imino-(1-oxo-(1H)-phthalazin-2-yl) methyl]benzenesulfonamide derivatives with in vitro activity against yeast-like fungi isolated from the oral cavity and respiratory tract of patients with candidiasis. These compounds were synthesized by the one-step or two-step reactions of 1-(2-alkylthiobenzensulfonyl)-2aminoguanidines with the appropriate ortho-carbonyl benzoic acids. The biological study revealed that new derivatives have shown significant growth-inhibitory activity, superior or comparable, than those of the reference drug fluconazole. The most promising activities were observed against Candida albicans, with inhibition at least 1-3 (12.5%-37.5%) of the eight tested strains at the low MIC level of <= 6.2-25 mu g/mL. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Multifunction luminogens have emerged as promising candidates in high-performance sensor and imaging systems. Concise approaches to the synthesis of such molecules are urgently required both for fundamental research and technological applications. In this study, a new symmetric ligand of di(2-hydroxyphenyl)phthalazine with multiple binding sites around a phthalazine unit was readily synthesized, which could be converted efficiently into an asymmetric luminogen (OBNDHPP) through the formation of oxygen-boron-nitrogen bonding. This molecule has a twistable it-extended backbone with a tetracoordinated boron core bearing two bulky phenyl groups, giving it abundant optical properties including a large Stokes shift piezochromism and aggregationinduced emission enhancement. Importantly, the presence of a free phenolic hydroxyl group in the backbone of OBN-DHPP enables the incorporation of various functional moieties into the asymmetric luminogen. As an example, polyethylene glycol (PEG)-modified luminogen (OBN-DHPP-PEG(45)) was synthesized. In the aqueous medium, OBN-DHPP-PEG(45) could self-assemble into spherical nanoparticles with low cytotoxicity and excellent emission performance as well as high solubility. The results of flow cytometry and fluorescence microscopy reveal that these nanoparticles could be internalized successfully by HeLa cells, demonstrating their potential application in bioimaging.

In this paper, two pyridazine-heterocycles-containing azaacenes 9,12-diphenylphenanthro[4,5-fgh]phthalazine (DPPA) and 2,9-di-tert-butyl-4,7,11,14-tetraphenylpyridazino[4′,5′:9,10] phenanthro[4,5-fgh]phthalazine (TPPA) have been synthesized and fully characterized. The single crystal analysis of TPPA showed that TPPA molecule exhibits a twisted structure with the dihedral angel of 27 degrees between pyrene and pyridazine unit, which suppresses the pi-pi stackings in the solid state. The two-photon absorption properties of DPPA and TPPA were investigated, respectively, by using the femtosecond Z-scan technique. The results showed that both DPPA and TPPA showed moderate two-photon absorption cross-section values, and the larger one was found to be 454 GM with TPPA. Obviously, the introduction of pyridazine ring into the skeleton of acenes forming a A-D-A structure could lead to a much larger two-photon absorption coefficient and two-photon absorption cross section.
