Anti-inflammatory and Antimicrobial Activity of Some Novel Quinazolinones
A series of 3-Amantadinyl-2-[(4-amino-3-aryl-5-ylthio)-1,2,4-triazolo]methyl)quinazolin-4-one 5(a-i) were prepared by the reaction of 3-Amantadinyl-2-[(4-acetamido-3-aryl-5-ylthio)-1,2,4-triazolo]methyl)quinazolin-4-one 4(a-i) with various 3-aryl-4-acetamido-5-mercapto triazoles. The compounds 5(a-i) biologically evaluated for their antiinflammatory and antibacterial activities.Structures of th...
متن کاملNew Isoxazolidine-Conjugates of Quinazolinones-Synthesis, Antiviral and Cytostatic Activity.
A novel series of (3-diethoxyphosphoryl)isoxazolidines substituted at C5 with various quinazolinones have been synthesized by the 1,3-dipolar cycloaddition of N-methyl-C-(diethoxyphosphoryl)nitrone with N3-substitued 2-vinyl-3H-quinazolin-4-ones. All isoxazolidines were assessed for antiviral activity against a broad range of DNA and RNA viruses. Isoxazolidines trans-11f/cis-11f (90:10), trans-...
متن کاملMicrowave Assissted Synthesis and Antimicrobial Activity of Some Newer Mannich Bases
A series of Mannich bases 5a-5h were synthesized by the reaction of 5–{2–(ethylthio)–1H– benzimidazol–1–yl}–methyl–1,3,4–oxadiazole–2–thione 4 with formaldehyde and appropriate amines by conventional and microwave techniques. The reaction rate and yields were enhanced under microwave irradiation technique rather than conventional technique. Structures were characterized by means of spectral dat...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
