Computational techniques are widely used to reduce costs associated with new drug development with the ability to bind a specific molecular target. These studies need a Brookhaven protein data bank structure sample of the enzyme interaction with an inhibitor of adequate size. In this context, a new computational methodology is postulated to be used when there are no published samples fulfilling this requirements. In this study, 7 compounds, which showed anti-T. cruzi, L. donovani and L. infantum properties, and proved to be inhibitors of their Fe-SOD enzymes, have been theoretically evaluated against related parasites Fe-SOD enzymes, which have been proposed as targets for antiparasitic drugs. This methodology may be applied to similar cases and also to generate starting structures to be used with different CADD methods

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 482-05-3, Name is [1,1′-Biphenyl]-2,2′-dicarboxylic acid, molecular formula is C14H10O4.

Cost-effective fabrication of white organic light-emitting diodes (WOLED) is meaningful toward commercial application of environment-friendly solid-state lighting sources. Electroluminescent efficiency and color quality are two opposite performance characteristics facing solution processed WOLEDs requiring balanced consideration. Herein, a recently synthesized molecule of 4,4′-(9,9′-(1,3-phenylene) bis(9H-fluorene-9,9-diyl)) bis(N,N-diphenylaniline) (DTPAFB) is introduced as a host material for solution processed all-phosphor WOLEDs, embracing four well-known molecules which are blue iridium (III) bis(2-(4,6-difluorophenyl) pyridinato-N,C-2)(picolinate) (FIrpic), green iridium (III) bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2,O-4)[Ir(ppy)(2)(acac)], and orange iridium (III) bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) [Ir(bt)(2)(acac)] plus a home-made red phosphor of iridium (III) tris(1-(2,6dimethylphenoxy)-4-(4-chlorophenyl) phthalazine) [Ir(MPCPPZ)(3)]. Illumination quality white light with high brightness, high efficiency, suitable correlated color temperature (CCT), high color-rendering index (CRI), and stable electroluminescent (EL) emission is obtained. A stable white emission with a CRI over 70, Commission Internationale de L’Eclairage (CIE) of (0.37, 0.42), and high EL efficiency of 19.6 lm W-1 at high luminance of 2000 cd m(-2) for blue/orange complementary color WOLEDs is demonstrated. The optimized red/green/blue three primary color WOLEDs show improved CRI up to 81, moderate high efficiency of 25.8 cd A(-1), 14.4 lm W-1, and EQE of 13.9%. Furthermore, the red/green/blue/orange four primary color WOLEDs show the optional balance between color quality and EL efficiency with high CRI of around 81-83 and medium CCT of 3755-3929 K which is warm and soft to human eyes. At an illumination relevant luminance of 1000 cd m(-2), the total power efficiency reaches 33.6 lmW(-1), and still remains 30.2 lm W-1 at 3000 cd m(-2), approaching the efficiency of state-of-the-art fluorescent-tube (40 – 70 lm W-1), potentially suitable as an environment-friendly solid-state lighting source. This work indicates that developing high performance host materials and highly efficient phosphors and carefully combining them with common phosphors is an effective way toward high performance WOLEDs.

Science experiments are a great way to spark their curiosity, 502496-34-6, Name is 4-Bromo-2-fluoro-6-nitrotoluene, SMILES is CC1=C([N+]([O-])=O)C=C(Br)C=C1F, belongs to phthalazine compound. In a article, author is Fallah-Ghasemi Gildeh, Sara, introduce new discover of the category.

Benzylation of DBU followed by anion exchange of the resulting salt with trifluoroacetate gave nearly quantitatively the ionic liquid [Bn-DBU][TFA]. It is shown here to be an efficient catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dionesviathe three-component reaction of phthalhydrazide, aromatic aldehydes, and active alpha-methylene nitriles. DFT calculations at the B3LYP/SVP level and the experimental results are in agreement with a three-step mechanism for this reaction. Based on the DFT calculations, the catalytic effect largely arises from the intrinsic ionic properties of the ionic liquid rather than its action as a simple base. These calculations also predict the existence of two close-in-energy activated complexes whose rate determining roles and energies depend on their interaction with the anionic component of the ionic liquid, as [Bn-DBU][TFA] has shown a higher catalytic activity than [Bn-DBU][OAc]. This mechanistic approach opens up new and promising insights into the rational design of ionic liquid catalysts for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones. The synthetic method presented here has several prominent advantages.

Novel one-pot synthesis naphtho[2,3-g]phthalazine (1a-1k) of Mannich base derivatives can be achieved via grindstone chemistry using a Tel-Cu-NPs (telmisartan-copper nanoparticles) catalyst. This method offers efficient mild reaction conditions and high yields. Tyrosinase inhibitory activity was evaluated for all synthesized compounds, along with analysis of kinetic behavior and molecular docking studies. The synthesized compound, 1c was (IC50 = 11.5 mu M) more active than kojic acid (IC50 = 78.0 mu M). Lineweaver Burk plots were used to analyze the kinetic behavior of the most active compound 1c, it was reversible and competitive behavior. Compound 1c and kojic acid occurred in the presence of 2-hydroxyketone, which has the same inhibitory mechanism. The molecular docking of compound 1c and the control kojic acid were docked against 2Y9X protein via the Schrodinger Suite. The compound 1c showed a respectable dock score (-5.6 kcal/mol) compared to kojic acid with a dock score of (-5.2 kcal/mol) in the 2Y9X protein. Cytotoxicity activity was also evaluated by using HepG2 (liver), MCF-7 (breast), and HeLa (cervical) cancer cell lines, and high activity for 1c (GI(50) = 0.01, 0.03, and 0.04 mu M, respectively) against all cell lines was found compared to standard and other compounds. Therefore, this study succeeded in testing a few promising molecules as potential antityrosinase agents.

Tetrabutyl phosphonium sulfate ([TBP](2)SO4), as novel room-temperature ionic liquid (RTIL), was synthesized by a simple cost-effective method, characterized by H-1, C-13, P-31 NMR and FT-IR spectrophotometry. The newly prepared catalyst was used as an efficient catalyst in some four multicomponent reactions (4MCRs) e. g., to synthesis pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine. This green method has several advantages such as short reaction time, using simple methods to prepare catalysts and products, easy operation and high efficiency of products. In addition, the catalyst can be easily recovered and reused several times with reduced average activity. Graphic abstract

The abilities of phthalazine derivatives, including phthalazine (PT), phthalazone (PTO) and phthalhydrazide (PTD), to inhibit the corrosion of mild steel in 1 M HCl at 30 degrees C were studied using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. Theoretical calculations were performed to investigate the electronic structures of the PT derivatives. Our results showed that the inhibition efficiencies of these derivatives improved with increases in concentration. The data also showed that PTD < PT < PTO in terms of the inhibiting efficiency. Theoretical calculations also revealed that PTO is expected to be the best inhibitor among the studied phthalazine derivatives. (C) 2011 Elsevier Ltd. All rights reserved.
