Synthesis, antiviral, antituberculostic and antibacterial activities of some novel, 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-(substituted imino) pyrimidines.
A variety of novel 4-[(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-substituted imino] pyrimidines were synthesized by reacting 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines with different substituted aromatic aldehydes, with coumarin and with chloroisatin. The 4-(4'-chlorophenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines were synthesized by reacting 3-(4'-substituted phenyl)...

Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...
متن کاملDesign and Synthesis of Some Novel 4-(4-substituted aryl) Semicarbazones as Anticonvulsant Agents
In the present study, a series of 4-(4-substituted aryl) semicarbazones were synthesized from substituted anilines and subsequently evaluated for their anticonvulsant activities. The anticonvulsant activities were established by the anticonvulsant drug development (ADD) programme NIH, USA using experimental animal, adult male FCM mice (20-25 g) and adult Sprague-Dawley rats (100-150 g) and scre...
متن کاملSynthesis of isopropyl-substituted anthraquinones via Friedel–Crafts acylations: migration of isopropyl groups
Friedel-Crafts reactions of isopropyl-substituted benzenes with phthalic anhydride in the presence of aluminium trichloride, followed by cyclization of the products with strong sulfuric acid give, as expected, anthraquinones. The syntheses, however, often afford more than one anthraquinone. In some cases the isopropyl groups migrate cleanly to other ring positions; in other cases they are lost.
متن کاملSynthesis of Substituted 2-Pyridyl-4-phenylquinolines
Abstract: The acid-catalyzed condensation of o-aminobenzophenones with aromatic acetyl derivatives, in a basic methanol/tetrahydrofuran medium, has been used to prepare a series of substituted 2-pyridyl-4-phenylquinolines. Derivatives having two aza binding sites can act as asymmetric bidendate ligands to complex transition metals such as ruthenium, osmium or iridium. All the compounds were cha...
