A manganese-catalyzed oxidative kinetic resolution of cyclic benzylic ethers through asymmetric C(sp(3))-H oxidation is reported. The practical approach is applicable to a wide range of 1,3-dihydroisobenzofurans bearing diverse functional groups and substituent patterns at the alpha position with extremely efficient enantiodiscrimination. The generality of the strategy was further demonstrated by efficient oxidative kinetic resolution of another type of five-membered cyclic benzylic ether, 2,3-dihydrobenzofurans, and six-membered 6H-benzo[c]chromenes. Direct late-stage oxidative kinetic resolution of bioactive molecules that are otherwise difficult to access was further explored.

A pair of novel lipopeptide epimers, sinulariapeptides A (1) and B (2), and a new phthalide glycerol ether (3) were isolated from the marine algal-associated fungus Cochliobolus lunatus SCSIO41401, together with three known chromanone derivates (4-6). The structures of the new compounds, including the absolute configurations, were determined by comprehensive spectroscopic methods, experimental and calculated electronic circular dichroism (ECD), and Mo-2 (OAc)(4)-induced ECD methods. The new compounds 1-3 showed moderate inhibitory activity against acetylcholinesterase (AChE), with IC50 values of 1.3-2.5 mu M, and an in silico molecular docking study was also performed.

Chiral alpha-substituted 1,3-dihydroisobenzofurans are key scaffolds in a number of bioactive natural products and synthetic pharmaceuticals. However, catalytic asymmetric approaches have been rarely developed. Here, a redox deracemization technology is adopted to address the catalytic asymmetric synthesis. A broad range of alpha-aryl substituted 1,3-dihydroisobenzofurans are effectively deracemized in high efficiency with excellent ee. alpha-Alkynyl substituted ethers were also compatible with the deracemization technology.

Atherosclerosis is initiated by the local inflammation response to lipid deposition, and the most commonly administered antiatherogenic drugs are statins. Based on traditional Chinese medicine (TCM) evidence, we aimed to find effective therapeutic agents other than statins. A TCM, Suxiao Jiuxin Pill (SX), has been widely used in curing cardiovascular diseases for thirty years. In this paper, a combination of pharmacologic studies and RNA-Seq transcriptomics were employed to explore the pharmacodynamic advantages of SX over atorvastatin in the ApoE(-/-) mouse. 113 differentially expressed genes that were modulated by SX to a greater degree than atorvastatin were primarily involved in immunomodulation. The expression of BTK, AKT1, c-jun and CD137 was effectively regulated by SX with better effect than atorvastatin. Then a dual-luciferase reporter assay for NF-kappa B inhibition was applied to identify active components in SX. As a result, Senkyunolide A (Sen A) and Ligustilide (Lig), the key immunomodulatory ingredients in SX, were found to inhibit the expression of CD137 which is a diagnostic biomarker in atherosclerosis. It was further confirmed that Lig effectively suppressed the expression of AP-1 and NF-kappa B and the phosphorylation of AKT. Therefore, Lig achieved its CD137 inhibition through suppressing the expression of AP-1 and AKT/NF-kappa B signaling pathway, which partly explains the immunomodulation of SX in atherosclerosis. Above all, phthalides may be the primary components of SX improving immune and inflammation response in atherosclerosis.

The Name is Isobenzofuran-1(3H)-one. Through research, I have a further understanding and discovery of 87-41-2.

A great amount of insoluble phosphate in agricultural soils is not available for crops. Three strains of bacteria (Bacillus megaterium YLYP1 Pseudumonas prosekii YLYP6 and Pseudomonas sp. YLYP29) isolated from activated sludge and soil could efficiently solubilise tricalcium phosphate. In particular, the novel strain P. prosekii YLYP6 produced 716 mg L-1 of available phosphate within 6 days under the optimal culture conditions [20 degrees C, pH 7.9, inoculum size of 0.5% (v:v)] determined by response surface methodology. P. prosekii YLYP6 demonstrated efficient phosphate solubilisation in response to broad variations in pH (5-9) and temperature (15-35 degrees C). The phosphate solubilisation curves of the strains fit well with a first-order kinetic model (R-2 > 0.939), with a halt-life of 1.51-5.94 d for 5.0 g L-1 calcium phosphate. Continuous culture experiments combined with scanning electron microscopic observations and gas chromatography-mass spectrometry analysis revealed that 2,3-dimethylfumaric acid, gluconic and N-butyl-tert-butylamine that were produced by P. prosekii YLYP6 were responsible for phosphate solubilisation by supplying H+ ions and organic anions. Efficient phosphate solubilisation in actual soil by P. prosekii YLYP6 demonstrated the strong application potential to reduce the use of chemical P fertilisers and the resulting agricultural nonpoint pollution.

For the first time, H3PO3 was used as both the reducing reagent and the promotor in the reductive benzylation reactions with aryl aldehydes. By using a H3PO3/I-2 combination, various aromatic aldehydes underwent iodination reactions and Friedel-Crafts type reactions with arenes via benzyl iodide intermediates, readily producing benzyl iodides and diarylmethanes in good yields. Intramolecular cyclization reactions also took place, giving the corresponding cyclic compounds. This new strategy features easy-handling, low-cost, and metal-free conditions.

Background: Acute myeloid leukemia (AML) is a devastating hematologic malignancy with a high mortality. The nuclear receptors Nur77 and NOR-1 are commonly downregulated in human AML blasts and have emerged as key therapeutic targets for AML. Methods: This study aimed to identify Z-ligustilide (Z-LIG), the main phthalide of Rhizoma Chuanxiong, as a potential agent that can selectively target AML. The anti-AML activity of Z-LIG was evaluated in vitro and in vivo, and the effect and underlying mechanisms of Z-LIG on the restoration of Nur77 and NOR-1 was determined. Moreover, the role of Nur77 and NOR-1 in the regulation of Z-LIG-induced apoptosis and differentiation of AML cells was explored. Results: Z-LIG preferentially inhibited the viability of human AML cells, as well as suppressed the proliferation and colony formation ability. Notably, a concentration-dependent dual effect of Z-LIG was observed in AML cells: inducing apoptosis at relatively high concentrations (25 mu M to 100 mu M) and promoting differentiation at relatively low concentrations (10 mu M and 25 mu M). Importantly, Z-LIG restored Nur77 and NOR-1 expression in AML cells by increasing Ace-H3 (lys9/14) enrichment in their promoters. Meanwhile, Z-LIG enhanced the recruitment of p300 and reduced the recruitment of HDAC1, HDAC4/5/7, and MTA1 in the Nur77 promoter and enhanced the recruitment of p-CREB and reduced HDAC1 and HDAC3 in the NOR-1 promoter. Furthermore, Z-LIG-induced apoptosis was shown to be correlated with the mitochondria localization of Nur77/NOR-1 and subsequent Bcl-2 conformational change, converting Bcl-2 from a cyto-protective phenotype into a cyto-destructive phenotype. ZLIG-promoted differentiation was found to be related to Nur77/NOR-1-mediated myeloid differentiation-associated transcription factors Jun B, c-Jun, and C/EBP beta. Finally, silencing of Nur77 and NOR-1 attenuated anti-AML activity of Z-LIG in NOD/SCID mice. Conclusions: Our study suggests that Z-LIG may serve as a novel bifunctional agent for AML by restoring Nur77/NOR-1-mediated apoptosis and differentiation

The present study analyses the thermowell system for monitoring temperatures in a fixed bed catalytic reactor for the highly exothermic partial oxidation of o-xylene to phthalic anhydride. Particle-resolved computational fluid dynamics (CFD) simulations are presented for the cases of randomly-packed spheres inside cylindrical tubes with tube-to-particle diameter ratios (N) of 3.96, 5.96 and 7.99. Results are obtained for each N value for cases with inner thermowell radius to outer tube radius ratios of 0.0 (no thermowell), 0.05, 0.1 and 0.2. Comparisons of radial void fraction and axial velocity profiles, axial pressure drop and axial temperature profiles under reaction conditions are presented. The presence of the thermowell did change the mass and heat transfer and reaction inside and around the particles, especially at the bed center. The configurations of catalyst particles were rearranged, leading to changes in voidage, flow and temperature profile. The axial temperature profiles from the thermowells differed from the profiles in the undisturbed beds. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
