Synthesis and study of new 5-substituted 1-acetyl-4-phenyl-3-pyrrolin-2-ones as potential antitumor agents

The treatment of 1-acetyl-5-bromo-4-phenyl-3-pyrrolin-2-one with appropriate silver salts in benzene promotes the substitution of bromine with chloride, fluoride, nitrite, nitrate, and thiocyanate groups. Biological testing of the newly synthesized compounds resulted in the discovery of moderate indoleamine 2,3-dioxygenase and matrix metalloproteinase inhibiting properties for NO2 and SCN derivatives in combination with low antitumor effect in vivo. However, testing of the NO2 derivative in mice with transplanted 4T1 mammary and CT-26 mouse colon carcinomas led to a considerable decrease in tumor volume and lung metastases without undesirable toxic effects evidencing potent tumor supressing properties.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 155899-66-4, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/155899-66-4.html.

Simultaneous synthesis of thioesters and iron-sulfur clusters in water: two universal components of energy metabolism

Thioesters are important intermediates in both synthetic organic and biosynthetic reaction pathways. Here we show that thioesters can be synthesized in an aqueous reaction between thioacetate and thiols. The reaction can be coupled to a second reaction between sulfide and either ferrous or ferric iron, which drives the reaction forward. We furthermore demonstrate that sulfide released during thioester formation can be used in the synthesis of peptide bound [Fe-S] clusters, which like thioesters, are ancient components of metabolism. Together our results reveal a primordial linkage between high-energy ester formation and redox chemistry.

Organocatalyzed Asymmetric Mannich Reaction: An Update

The Mannich reaction is a multicomponent reaction resulting in aminoalkylation of an acidic proton placed next to a carbonyl functional group. It involves an appropriate carbonyl compound, such as formaldehyde and a primary or secondary amine or ammonia. The final product is a beta-amino-carbonyl compound known as a Mannich base. Reactions between aldimines and alpha-methylene carbonyls are also considered as Mannich reaction since these imines are generated from the reaction of amines and aldehydes. It comprises the reaction of primary or secondary amines or ammonia, formaldehyde and appropriate alpha-CH-acidic compounds (nucleophiles) such as carbonyl compounds having alpha-CH-acidic, nitriles, acetylenes, aliphatic nitro compounds, alpha-alkyl-pyridines or imines. Owing to the development of asymmetric organocatalysis, reports on asymmetric Mannich reaction have been drastically increased. The asymmetric Mannich reaction offers access to enantioenriched beta-amino ketones or beta-amino aldehydes, which are present as a scaffold in several natural products. Organocatalysts have been developed not only as a supplement to metal-catalyzed reactions or to biocatalysis, but nowadays, they are extensively used for the synthesis of various optically pure compounds that could not be achieved via metal- or biocatalyzed reactions. In this review, we try to update the advances in organocatalyzed asymmetric Mannich reactions, covering the recent advances of the subject from 2008 to date.

Synthesis and herbicidal activity of novel 3-alkoxycarbonyl-3-aryl-2, 3-dihydro-2-oxo-1H-pyrrole derivatives

In the course of efforts to find novel compounds with improved crop safety in transplanted rice by the modification of 1-[1-(3,5 -dichlorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (1a), which was reported to have excellent herbicidal activity against paddy weeds, 2,3-dihydro-2-oxo-1H-pyrrole derivatives with a quaternary carbon atom having an alkoxycarbonyl group at the alpha-position of the cyclic amide were synthesized and examined. Among these compounds, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate (2a) was not only active against Echinochloa oryzicola and Scirpus juncoides but also compatible with transplanted rice even in harsh conditions. On the bask of Preliminary experimental results. it was thought that 2a would generate the corresponding 2-oxo-3-pyrrolin (la) through the metabolic degradation of the methoxycarbonyl moiety.

Regioselective Transition-Metal-Free Synthesis of 2-(Trimethylsilylmethylene)pyrrol-3-ones by Thermal Cyclization of Acetylenic Enamines

Acetylenic enamines generated in situ from readily available enynones and primary amines undergo thermal cyclization in diphenyl ether providing easy access to 4-aryl-2-(trimethylsilylmethylene)-1,2-dihydro-3H-pyrrol-3-ones. This reaction is inherently versatile, allowing for variations of substituents in both enynone and amine. Full regioselectivity along with short reaction time (1-2 h) and simple workup afford single products in good to excellent isolated yields. Fluorescent properties of the obtained compounds were studied.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 155899-66-4 is helpful to your research. HPLC of Formula: https://www.ambeed.com/products/155899-66-4.html.

Evaluating the efficacy of a newly developed palm-based process aid on nitrile rubber composites

The exploration of bio-based process aid is still ongoing in the effort to replace petroleum-based process oil. In this study, the efficacy of a newly developed palm-based process aid (Bio) on nitrile rubber (NBR) composites was investigated by varying its concentration from 0.0 to 10.0 phr. A comparison was made against a commercial oil (CO), i.e. naphthenic oil in terms of Mooney viscosity, cure characteristics, morphology, physical, and chemical properties. Results revealed that the use of Bio as process aid improves the processability of rubber by lowering the Mooney viscosity, enhancing filler dispersion, and lowering loss tangent values. Tensile properties and compression sets of CO-NBR composites were slightly better compared to Bio-NBR composites. Interestingly, Bio-NBR composites showed better ageing properties, especially at higher process aid content. Higher retentions of tensile strength and elongation at break and lower compression sets of aged Bio-NBR compared to CO-NBR composites were observed, which are possibly contributed by the good compatibility of Bio with aged rubber. Thermogravimetric analysis showed that the thermal stability of Bio-NBR composites were slightly better than CO-NBR composites. Based on these findings, the use of Bio (>= 7.5 phr) as process aid significantly improved the processability of rubber with some enhancement in ageing properties of composites that is desirable and ideal for various applications such as for the production of automotive components.

The ozonation of N-Boc-protected 3-methylidene-4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one resulted in its transformation into 3-hydroxy4-phenyl-5-(trifluoromethyl)-3-pyrrolin-2-one. Catalytic hydrogenation of its O-Boc-protected derivative introduced a way to reduce the double bond in combination with elimination of the hydroxy group leading to the formation of 4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one as an intermediate in the synthesis of fluorinated E1R structural derivative 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide.

Quenching of pyrene derivatives’ fluorescence by nitroxide radicals in sodium dodecyl sulfate micellar solutions

Dynamic fluorescence quenching measurements have been performed on pyrene derivatives (pyrene (Py), 1-pyrenebutanoic acid (PBA), and 1-pyrenedodecanoic acid (PDA)), using as quenchers nitroxide free radicals (2,2,6,6-tetramethyl-1,1-piperidinyloxyl, 4-hydroxy-2,2,6,6-tetramethyl-1,1-piperidinyloxyl, and 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (TEMN)) in aqueous solutions of sodium dodecyl sulfate. The mean aggregation number values are comparable with the literature data only when the partition coefficient of the quencher is higher than 1100 M-1. It is shown that the dynamic fluorescence quenching for the PBA/TEMN pair cannot be described by the Infelta-Tachiya model owing to the fact that the intramicellar quenching rate constant is lower than the exit rate constant of the quencher from the micelle. The average location of the fluorescent probes is also discussed, Py and PDA having the pyrenyl moieties located at approximately the same depth in the micellar core, while in the case of PBA the pyrenyl moiety is buried deeper.
