Synthesis of 3- Benzylidene, 5-Substituted 3-Benzylidene, 3- Hetarylmethylene and 5-Substituted Hetarylmethylene Derivatives of In- dolin-2-ones
A wide variety of titled compounds, several of which have neuro-protecting properties has been prepared in yields ranging between 70 to 90%. The compounds were identified by 1 HNMR, 13 C NMR, 1D and 2D NOE analysis, and HRMS. An investigation of the effect of certain 5-substitutuents on the E to Z ratios in DMSO-d6 was carried out. The 5nitro and 5-acetyl substituents were not isomerized, where...
متن کاملA comparative QSAR study of aryl-substituted isobenzofuran-1(3H)-ones inhibitors
A comparative workflow, including linear and non-linear QSAR models, was carried out to evaluate the predictive accuracy of models and predict the inhibition activity of a series of aryl-substituted isobenzofuran-1(3H)-ones. The data set consisted of 34 compounds was classified into the training and test sets, randomly. Molecular descriptors were selected using the genetic algorithm (GA) as a f...
متن کاملPhenyl Substituted 4-Hydroxypyridazin-3(2H)-ones and 5-Hydroxypyrimidin-4(3H)-ones: Inhibitors of Influenza A Endonuclease
Seasonal and pandemic influenza outbreaks remain a major human health problem. Inhibition of the endonuclease activity of influenza RNA-dependent RNA polymerase is attractive for the development of new agents for the treatment of influenza infection. Our earlier studies identified a series of 5- and 6-phenyl substituted 3-hydroxypyridin-2(1H)-ones that were effective inhibitors of influenza end...
متن کاملMicrowave-assisted synthesis of substituted 2-(benzylthio)imidazo[1,2a]pyrimidin-5-ones.
A microwave-assisted solid-phase synthesis of 2-(benzylthio)imidazo[1,2a]pyrimidin-5-ones has been developed. Using microwave irradiation, the reaction time was significantly reduced from a few days to 80 min. A representative set of 10 2-(benzylthio)-6,7-substituted-imidazo[1,2a]pyrimidin-5-ones was prepared. These compounds were subsequently N-alkylated and formylated in good yields.
متن کاملA Steiner 5-Design on 36 Points
All known Steiner 5-designs previously had an order q + 1 where q 3 (mod 4) is a prime power and PSL(2; q) was admitted as a group of automorphisms of such a design. In this paper we present a 5-(36; 6; 1) design admitting PGL(2; 17) C 2 as a group of automorphisms. The design is unique with this automorphism group and even for the commutator group PSL(2; 17) id 2 of this automorphism group the...
