Tel-Cu-NPs Catalyst: Synthesis of Naphtho[2,3-g]phthalazine Derivatives as Potential Inhibiters of Tyrosinase Enzymes and Their Investigation in Kinetic, Molecular Docking, and Cytotoxicity Studies

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.

Application of O-sulfonic acid poly(4-vinylpyrrolidonium) chloride as an efficient polymer-supported catalyst in the rapid synthesis of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products

In this work, a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products were efficiently synthesized for the first time using O-Sulfonic acid poly(4-vinylpyrrolidonium) chloride ([PVP-SO3H]Cl) as an eco-friendly polymer-supported catalyst. At first, the catalyst preparation process was optimized based on the chlorosulfonic acid amount and the sulfonation time to obtain a catalyst with the maximum acidity content. The maximum acidity content for [PVP-SO3H]Cl was obtained to be 3.31 mmol g(-1). Then, the optimized [PVP-SO3H]Cl was used as a catalyst for the synthesis of a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products. It was observed that only 10 mg of the catalyst was enough to catalyze these reactions under mild conditions, and the corresponding products were obtained in high to excellent yields. Moreover, the catalyst could be repeatedly used for at least five times without a noticeable decrease in its catalytic activity.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 54381-16-7, you can contact me at any time and look forward to more communication. COA of Formula: C10H18N2O6S.

beta-Cyclodextrin as a supramolecular catalyst for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives in water and their antimicrobial activities

An efficient and green method has been developed for the synthesis of 2H-indazolo[2,1-b]phthalazinetriones derivatives by employing 15 mol% beta-cyclodextrinvia a one-pot multicomponent reaction of aldehyde, dimedone, hydrazine hydrate with succinic anhydrideiphthalic anhydride in water at 80 degrees C for first time. The catalyst could be recovered and reused for four consecutive cycles without appreciable loss in catalytic activity and evaluated for in vitro antimicrobial activity against different Gram-positive and Gram-negative bacterial strains. The outcome of the screening study showed that compound 6d, 6f and 7n exhibited excellent activity against E. coil. Whereas, compound 6f and 6 h exhibited excellent activity against P. aeurginosa, and compound 6c, and 6e displayed again excellent activity against Staphylococcus aureus whereas compound 7o shows excellent activity against S. aureus and B. subtilis when compared with Ampicillin (standard control). The results indicated that maximum compounds are moderately effective against bacterial growth and their effectiveness is highest against standard drugs.

Base-promoted aerobic oxidation of N-alkyl iminium salts derived from isoquinolines and related heterocycles

Potassium tert-butoxide-promoted aerobic oxidation of N-alkyl iminium salts is reported. The reaction is atom-economical and environmentally friendly. Iminium salts derived from isoquinoline, quinoline, phenanthridine, phenanthroline, and phthalazine were successfully transformed into their corresponding unsaturated lactams with up to 95% yield under mild conditions in the absence of photocatalysts and metallic or organic catalysts. Owing to the general substrate scope, low cost, feasibility of scale up, wide availability of reagents, and green reaction conditions, this method shows great potential for preparing isoquinolones and related compounds. The method was applied for atom- and step-economical total synthesis of natural products such as norketoyobyrine.

Silver(I) complexes with phthalazine and quinazoline as effective agents against pathogenic Pseudomonas aeruginosa strains

Five silver(I) complexes with aromatic nitrogen-containing heterocycles, phthalazine (phtz) and quinazoline (qz), were synthesized, characterized and analyzed by single-crystal X-ray diffraction analysis. Although different AgX salts reacted with phtz, only dinuclear silver(I) complexes of the general formula {[Ag(X-O)(phtz-N)](2)(mu-phtz-N,N’)(2)} were formed, X = NO3- (1), CF3SO3- (2) and ClO4- (3). However, reactions of qz with an equimolar amount of AgCF3SO3 and AgBF4 resulted in the formation of polynuclear complexes, {[Ag(CF3SO3-O)(qz-N)](2)}(n) (4) and {[Ag(qz-N)][BF4]}(n) (5). Complexes 1-5 were evaluated by in vitro antimicrobial studies against a panel of microbial strains that lead to many skin and soft tissue, respiratory, wound and nosocomial infections. The obtained results indicate that all tested silver(I) complexes have good antibacterial activity with MIC (minimum inhibitory concentration) values in the range from 2.9 to 48.0 mu M against the investigated strains. Among the investigated strains, these complexes were particularly efficient against pathogenic Pseudomonas aeruginosa (MIC = 2.9-29 mu M) and had a marked ability to disrupt clinically relevant biofilms of strains with high inherent resistance to antibiotics. On the other hand, their activity against the fungus Candida albicans was moderate. In order to determine the therapeutic potential of silver(I) complexes 1-5, their antiproliferative effect on the human lung fibroblastic cell line MRC5, has been also evaluated. The binding of complexes 1-5 to the genomic DNA of P. aeruginosa was demonstrated by gel electrophoresis techniques and well supported by molecular docking into the DNA minor groove. All investigated complexes showed an improved cytotoxicity profile in comparison to the clinically used AgNO3. (C) 2015 Elsevier Inc. All rights reserved.

Novel amalgamation of phthalazine-quinolines as biofilm inhibitors: One-pot synthesis, biological evaluation and in silico ADME prediction with favorable metabolic fate

A facile and highly efficient one-pot synthesis of phthalazine-quinoline derivatives is reported via four component reaction of phthalic anhydride, hydrazine hydrate, 5,5-dimethyl 1,3 cyclohexanedione and various quinoline aldehydes using PrxCoFe(2-x)O(4) (x = 0.1) nanoparticles as a catalyst. The synthesized compounds have been evaluated for anti-biofilm activity against Pseudomonas aeruginosa and Candida albicans. The compounds 12a (IC50 = 30.0 mu M) and 12f (IC50 = 34.5 mu M) had shown promising anti-biofilm activity against P. aeruginosa and C. albicans, respectively, when compared with standards without affecting the growth of cells (and thus behave as anti-quorum sensing agents). Compounds 12a (MIC = 45.0 mu g/mL) and 12f (MIC = 57.5 mu g/mL) showed significant potent antimicrobial activity against P. aeruginosa and C. albicans, respectively. Thus, the active derivatives were not only potent biofilm inhibitors but also efficient antimicrobial agents. In silico ADME and metabolic site prediction studies were also held out to set an effective lead candidate for the future antimicrobial drug discovery initiatives. (C) 2016 Elsevier Ltd.
