Ultrasonic Assisted Synthesis of 2, 3-Dihydroquinazolin-4(1H)-ones Involving Three-Component Reaction of Isatoic Anhydride, Amines and Pyrazole Carbaldehydes Catalyzed by [γ-Fe2O3@HAp-SO3H]
The combination of [γ-Fe2O3@HAp-SO3H] as a catalyst and ultrasonic effect catalyzed the synthesis of diverse derivatives of 2, 3-dihydroquinazolin-4(1H)-ones which is reported in this study. The products were synthesized via the one-pot three-component reaction of isatoic anhydride, amines and pyrazole carbaldehydes in water: EtOH catalyzed by recoverable [γ-Fe2O3@HAp-SO3H]. This paper conducted a Read More

Glucosides from the Fresh Flowers of Juglans regia L. and Their Biological Evaluation
Authors: Haibo Wang and Xikui LiuThe chemical investigation of the EtOAc extract of the fresh flowers of Juglans regia L. resulted in a new α-tetralonyl glucoside (1) and two known glucosides (2-3). The structure of the new compound was determined by extensive 1D and 2D NMR spectroscopic analysis and HRESIMS. The biological evaluation of the obtained glucosides showed that compound 1 and 3 displayed good antioxidant and antibacterial activities. T Read More

Antioxidant Properties of Synthesis Nanometallic Pd-Ni@2-Mercaptoethanol as Effective Catalyst for Suzuki-Miyaura Reactions
Authors: Khemais Said, Ali Mesni and Ridha B. SalemThe palladium-catalyzed Suzuki coupling reaction is one of the most efficient strategies for constructing a carbon-carbon bond. In recent years, bimetallic catalysts have become candidates for the Suzuki coupling reaction. In this work, Pd-Ni@2-Mercaptoethanol nanoparticles were synthesized for the Suzuki-Miyaura cross-coupling of arylboronic acids with aryl bromides, in the N,Ndimethylformamide/ water mixture Read More

New Chalcone Derivative: Synthesis, Characterization, Computational Studies and Antioxidant Activity
Authors: Reşat Ustabaş, Nevin Süleymanoğlu, Namık Özdemir, Nuran Kahriman, Ersan Bektaş and Yasemin ÜnverA new chalcone derivative, called as 1-(4-(benzylideneamino)phenyl)-3-(furan-2-yl)prop-2- en-1-one (I), was synthezised and characterized by spectral methods (infrared (IR) and proton and carbon- 13 nuclear magnetic resonance (1H- and 13C-NMR) spectroscopy). A computational study was performed by the density functional theory (DFT) method. Spectral data of compound I optimized by using 6-311G(d,p) and 6-311+ Read More

Novel 1,3,4-Thiadiazole Linked Amide Derivatives of Pteridone: Synthesis and Study of Anticancer Activities
Cancer is a second leading cause of death after heart attack, in developing as well as undeveloped countries. It is caused by unregulated growth and metastasis of the abnormal cancer cells. Cancer can be cured by radiation, immunotherapy and chemotherapy, among them; chemotherapy is a good treatment for cancer, in which chemotherapeutic drug is used. The anticancer activity of newly synthesized compounds (13a-j) w Read More

A Scalable Synthesis of Biaryl Unit of the HIV Protease Inhibitor Atazanavir
More LessAtazanavir is one of the most prescribed HIV-1 protease inhibitors approved by the FDA. It was the first protease inhibitor approved for once-a-day dosing to treat AIDS due to good oral bioavailability and favorable pharmacokinetic profile. This research aims to develop a new synthetic cost effective process for biaryl-hydrazine unit {tert-butyl 2-[4-(2-pyridinyl)benzyl]hydrazinecarboxylate} of atazanavir on a large scale. The s Read More

Magnetic Organic-Inorganic Hybrid Nano System Anchored Platinum Nanoparticles for Carbon Sequestration Reaction
Authors: Praveenkumar R. Upadhyay, Prashant Gautam and Vivek SrivastavaA new Pt metal based nano-catalytic system was developed using organic-inorganic magnetic framework followed by the user-friendly protocol in good yield. XRD, FTIR, TEM, BET, ICP-OES and solid-state NMR techniques were used to characterize our developed catalytic system. The wellcharacterized ionic liquid bridged-silica supported magnetic Pt nanoparticles were utilized for the selective hydrogenation of carbon Read More
