New naphthoquinone and monoterpenoid from Plumbago zeylanica

New naphthoquinone 2 and new monoterpenoid 3 were isolated from the stems of Plumbago zeylanica, and their structures were determined on the basis of 2D NMR spectroscopy. Absolute configuration of 3 was established by synthesis of its enantiomer. The new naphthoquinone 2 showed potent inhibitory activity against nuclear factor kappaB (NF-kappaB), equivalent to that of parthenolide, a known potent inhibitor of NF-kappaB.

Structures of proline utilization A (PutA) reveal the fold and functions of the aldehyde dehydrogenase superfamily domain of unknown function

Aldehyde dehydrogenases (ALDHs) catalyze the NAD(P)+- dependent oxidation of aldehydes to carboxylic acids and are important for metabolism and detoxification. Although the ALDH superfamily fold is well established, some ALDHs contain an uncharacterized domain of unknown function (DUF) near the C terminus of the polypeptide chain. Herein, we report the first structure of a protein containing the ALDH superfamily DUF. Proline utilization A from Sinorhizobium meliloti (SmPutA) is a 1233-residue bifunctional enzyme that contains the DUF in addition to proline dehydrogenase and L-glutamate-gamma-semialdehyde dehydrogenase catalytic modules. Structures of SmPutA with a proline analog bound to the proline dehydrogenase site and NAD+bound to the ALDH site were determined in two space groups at 1.7-1.9 A resolution. The DUF consists of a Rossmann dinucleotide-binding fold fused to a three-stranded -flap. The Rossmann domain resembles the classic ALDH superfamily NAD+- binding domain, whereas the flap is strikingly similar to the ALDH superfamily dimerization domain. Paradoxically, neither structural element performs its implied function. Electron density maps show that NAD+does not bind to the DUF Rossmann fold, and small-Angle X-ray scattering reveals a novel dimer that has never been seen in the ALDH superfamily. The structure suggests that the DUF is an adapter domain that stabilizes the aldehyde substrate binding loop and seals the substrate-channeling tunnel via tertiary structural interactions that mimic the quaternary structural interactions found in non-DUF PutAs. Kinetic data for SmPutA indicate a substrate-channeling mechanism, in agreement with previous studies of other PutAs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 87392-07-2, you can also check out more blogs about87392-07-2

Improvement of flavour quality and consumer acceptance during postharvest ripening in greenhouse peaches by carbon dioxide enrichment

In this study we assessed the impact of carbon dioxide enrichment (CDE) on flavour quality development of peach fruit, using peach trees grown in a greenhouse with a carbon-dioxide-enriched atmosphere. Fruit sugar, organic acids, volatiles contents and consumer acceptability were investigated, focusing on the period of postharvest ripening. Higher levels of sucrose, lactones, norisoprenoids, and lower levels of malic acid were found in CDE-treated fruit than those in the control fruit grown under normal conditions. We also measured significantly elevated amounts of pyruvic acid, precursors of volatile compounds, linoleic acid and linolenic acid as a result of CDE. Additionally, CDE-treated fruit were relatively well accepted by consumers compared to the control fruit. These results suggested that CDE can markedly improve the flavour quality and consumer acceptance of greenhouse-grown peaches. The possible mechanism could be that CDE increased precursors available for the biosynthesis of flavour compounds through regulation of photosynthesis.

alpha-trifluoromethylation of secondary and sterically hindered carboxylates with use of BrF3

Secondary esters and those with sterical hindrance at the beta carbon were reacted with base, carbon disulfide, and methyl iodide to produce methyl 2-carboalkoxydithioalkenoate (2). These compounds were reacted with BrF 3, forming the corresponding alpha-trifluoromethyl esters (3) along with 1,1-difluoro-2-trifluoromethyl-2-alkyl ethers (4). The products of type 4 have been transformed to derivatives of type 3, thus raising the overall yields of the target respective alpha-trifluoromethyl esters to 65-80%. The reaction is tolerant to different functional groups such as halogens, protected alcohols, esters, and lactones.
