4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones: biological isostere to 4-chloro-2-carbamoyl-4-isoxazolin-3-ones.
4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones (4) were designed on the basis of biological isosterism and prepared in four steps. Some of these compounds showed sufficient pre-emergent herbicidal activities against various kinds of weeds. Among the synthesized compounds, 2-(N-(4-chlorophenyl)-N-isopropylcarbamoyl)-4-ethylthio-5-methyl-4 -isoxazolin-3-one (4cd) exhibited the most promising activity.
متن کاملSYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
متن کاملPhotophysical study of the Dibenzylideneacetones and 3-Benzylidenethiochroman-4-ones
The Benzylideneacetones as part of a broad group of compounds, some of them of natural origin and found in several plant species [1], are of great interest in pharmaceutical and polymers areas [2, 3]. Also, these compounds have optical properties of interest in photonics [4,5]. Recently, it has been demostrated that 1,3-diketonate ligands in complex compounds with lanthanide ions, containing gr...
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 کاملTheoretical evaluation of medicinal properties for some of N-aryl-3-hydroxypyridine-4-ones derivative compounds
Today, the bidentate ligands 3-hydroxypyridin-4-ones (HPOs) as orally active iron chelating agents have been demonstrated to possess potential for treatment of some human diseases such as iron-overload in thalassaemic patients and malaria. In this research, a series of HPOs with different substitutes and position were theoretically invest
