Simple exploration of C10H12O5

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 121-79-9, in my other articles.

Soybean oil (SBO), rapeseed oil (RSO), peanut oil (PO), corn oil (CO), olive oil (OO), sunflower oil (SFO), rice germ oil (RGO), walnut oil (WO), torreya seed oil (TSO), and grapeseed oil (GSO) were used to investigate the formation of heterocyclic amines (HAs) in roasted beef patties. Seven HAs, including 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3,4-dimethyl-3H-imidazo[4,5-f]quinolone (MeIQ), 2-amino-3methyl-3H-imidazo[4,5-f]quinoxaline (IQx), 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (4,8-DiMeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 1-methyl-9H-pyrido[3,4-b]indole (harman), and 9Hpyrido[3,4-b]indole (norharman) were detected in control patties and patties with vegetable oils. GSO, SFO, and WO greatly reduced the content of PhIP and MeIQ. 1.25%TSO and 3.75% RGO showed higher inhibition effects on the more strongly mutagenic compounds (PhIP, MeIQ, IQx, 4,8-DiMeIQx, MeIQx). SBO, PO, and RSO promoted imidazoquin(ox)aline (MeIQ, MeIQx, 4,8-DiMeIQx, and IQx) and beta-carboline (harman and norharman); 1.25% SBO had the most significant promoting effect on total HA. This could be useful for the reduction of HA by selecting oils during cooking.

The applications of a newly designed chiral naphthyl-C2-indole bifunctional phosphine organocatalyst in stereoselective formal [4 + 2] cycloaddition reactions were reported. The chiral naphthyl-C2-indole skeleton was introduced to bifunctional phosphine organocatalysis for the first time, and excellent stereocontrol was achieved in two types of formal [4 + 2] cycloaddition reactions. With the optimal catalyst, a series of chiral spirooxindole and hydrodibenzofuran architectures were produced in moderate to good yields with excellent stereoselectivities (up to >99% ee, >20:1 dr).

Palladium-catalyzed ortho-amidation of indole-3-carboxylic acids with isothiocyanates by using the deciduous directing group nature of carboxyl functionality to afford indole-2-amides is demonstrated. Both C-H functionalization and decarboxylation took place in one pot, and hence, this carboxyl group served as a unique, deciduous (or traceless) directing group. This reaction offers a broad substrate scope as demonstrated for several other heterocyclic carboxylic acids like chromene-3-carboxylic acid, imidazo[1,2-a]pyridine-2-carboxylic acid, benzofuran-2-carboxylic acid, pyrrole-2-carboxylic acid, and thiophene-2-carboxylic acid. In the reaction using 2-naphthoic acid, of the two possible isomers, only one isomer of the amide was exclusively formed. The indole-2-amide product underwent palladium-catalyzed C-H functionalization to afford the diindole-fused 2-pyridones by combining two molecules of the indole moiety, with the elimination of an amide group from one of them, attached at the C3-position for the C-C/C-N bond formation. The structures of key products are confirmed by X-ray crystallography.

Association of 1-aminocyclo propane-1-carboxylate (ACC) deaminase producing bacteria with plants under abiotic stress conditions leads to stress alleviation not only by the regulation of ethylene concentration but also by the activation of numerous physiological and genetic mechanisms in plants. The objective of the current study was to evaluate the inoculation response of a plant-beneficial bacterial strain AQ12 on growth, physiological parameters, and expression of tiller responsive genes of rice plants grown under salt stress. The strain was identified as Burkholderia sp. based on 16S rRNA gene sequence analysis and it demonstrated promising ACC deaminase, indole-3-acetic acid (IAA) production, and phosphate solubilization traits in the presence of varying salt levels. The molecular confirmation of ACC deaminase activity was made by amplification and sequencing of the acdS gene. Inoculation of rice plants with the rifampicin-resistant derivative of Burkholderia sp. AQ12 resulted in a significant increase in length, dry matter, and cellular antioxidant enzyme levels together with the reduced levels of reactive oxygen species up to 50 mM salt stress. Furthermore, the inoculated plants revealed more than 2.0 fold increase in expression of the MOC1, OSH1, and OsTB1 genes up to 50 mM salt stress. It was concluded that inoculation of Burkholderia sp. AQ12 helped rice plants alleviate harmful salt stress effects by improving the growth, boosting the antioxidative defense system, and triggering the expression of tillering-responsive genes.

A palladium-dihydroxyterphenylphosphine (DHTP) catalyst was successfully applied to the direct C3-arylation of N-unsubstituted indoles with aryl chlorides, triflates, and nonaflates. This catalyst showed C3-selectivity, whereas catalysts with other structurally related ligands exhibited N1-selectivity. Complex formation between the lithium salts of the ligand and the indole is assumed to accelerate the arylation at the C3 position. Reactions using 3-alkylindoles afforded 3,3-disubstituted indolenines, which can be further converted to the corresponding indoline derivatives.

Described is an efficient oxidative dearomatization of indoles with TEMPO oxoammonium salt and a broad range of nucleophiles. Under very mild conditions, dearomative oxyalkynylation and oxy-alkenylation of indoles to structurally diverse 2,2-disubstituted indolin-3-ones were developed for the first time with high atom-economy. In addition, dearomative oxyarylation, oxyallylation, and oxycyanation of indoles were also demonstrated. Mechanism studies indicated that TEMPO oxoammonium salt served as the sole oxidant source through an electron donor-acceptor (EDA) intermediate.

Here, we present a proof-of-principle for a new high-throughput functional screening of metagenomic libraries for the selection of enzymes with different activities, predetermined by the substrate being used. By this approach, a total of 21 enzyme-coding genes were selected, including members of xanthine dehydrogenase, aldehyde dehydrogenase (ALDH), and amidohydrolase families. The screening system is based on a pro-chromogenic substrate, which is transformed by the target enzyme to indole-3-carboxylic acid. The later compound is converted to indoxyl by a newly identified indole-3-carboxylate monooxygenase (Icm). Due to the spontaneous oxidation of indoxyl to indigo, the target enzyme-producing colonies turn blue. Two types of pro-chromogenic substrates have been tested. Indole-3-carboxaldehydes and the amides of indole-3-carboxylic acid have been applied as substrates for screening of the ALDHs and amidohydrolases, respectively. Both plate assays described here are rapid, convenient, easy to perform, and adaptable for the screening of a large number of samples both in Escherichia coli and Rhodococcus sp. In addition, the fine-tuning of the pro-chromogenic substrate allows screening enzymes with the desired substrate specificity.

New indole derivatives of fusidic acid were synthesized by using the Fischer reaction. The obtained compounds were screened in vitro for antibacterial activity and were found to inhibit the growth of Staphylococcus aureus(MRSA, strain ATCC 43300) at concentrations comparable to fusidic acid. The obtained indole derivatives of fusidic acid were also characterized by relatively low cytotoxicity and minimal hemolytic effect at the highest concentration that was tested (32 mu g/ml).
