Download or read book Quinazolinone and Quinazoline Derivatives written by Ali Gamal Al-kaf and published by BoD – Books on Demand. This book was released on 2020-05-06 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the problems with modern public health is target searching for new highly effective medicinal preparations. Among those medicinal preparations are the natural and synthetic origins of quinazolinone-4 derivatives. Quinazolinone derivatives are reported to be physiologically and pharmacologically active. They also exhibit a wide range of activities such as anticonvulsant, antiinflammatory, antifungal, antimalarial, and sedative properties. Some of these compounds are identified as drugs used as diuretics, vasodilators, and antihypertensive agents. Moreover, sulfonamide derivatives have been widely used as bacteriostatic agents. Prompted by the above-mentioned facts and in conjunction with our ongoing program on the utility of readily obtainable starting material for the synthesis of heterocyclic systems of biological interest, we have decided to synthesize a series of quinazolinone derivatives having sulfonamide moiety with a potentially wide spectrum of biological responses.

Book excerpt: The proposed book gives an outline of the design, synthesis, characterization and various biological activities (antibacterial, antifungal, antituberculosis and anticancer) of novel urea/thiaourea functionalized quinazoline scaffolds. We have developed an efficient technique to introduced Suzuki C-C reaction on quinazoline and urea/thiourea moieties. The antimicrobial activity of synthesized analogs has been carried out against two Gram-positive bacteria, three Gram-negative bacteria and two fungi using paper disc diffusion method and agar streak dilution method. The synthesized analogs were further tested for their antimycobacterial activity against Mycobacterium tuberculosis H37RV using BACTEC MGIT and L. J. MIC methods. In addition, the synthesized analogs were also tested for their efficacy against prostate cancer PC3 cells using sulforhodamine B (SRB) assay to observe the variation in biological activity. The bioassay results revealed that majority of the compounds demonstrated excellent to moderate biological activity profiles. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR and mass spectrometric analysis.

Download or read book Quinoxalines written by Vakhid A. Mamedov and published by Springer. This book was released on 2016-04-26 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the fundamental aspects of quinoxaline chemistry: synthesis, reactions, mechanisms, structure, properties, and uses. The first four chapters present a survey of the developments in quinoxaline chemistry since the publication of the monograph on “Condensed Pyrazines” by Cheeseman and Cookson in 1979. These chapters give comprehensive coverage of all the methods of the synthesis of quinoxalines and the important quinoxaline-containing ring systems such as thiazolo[3,4-a]-, pyrrolo[1,2-a]-, and imidazo[1,5-a]quinoxalines. Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement). This book is of interest to researchers in the fields of heterocyclic and synthetic organic chemistry.
