Selective Synthesis of Benzothiophene-Fused Polycyclic, Eight-Membered N-Heterocycles via Amine-Mediated Three-Component Domino Strategy

A product-selective strategy was used to synthesize benzothiophene-fused polycyclic, eight-membered N-heterocycles via a three-component domino reaction of thioisatins under catalyst-free conditions. The reaction between tryptamine, thioisatin, and bromoacetophenone produced benzothiophene-fused polycyclic compounds. In contrast, using D-tryptophan methyl ester hydrochloride instead of tryptamine afforded benzothiophene-fused eight-membered N-heterocycles. DFT calculations showed that the benzothiophene-fused polycyclic compounds formed via the Pictet-Spengler reaction. However, the ester group in D-tryptophan methyl ester hydrochloride changed the reaction pathway and produced benzothiophene-fused eight-membered N-heterocycles.

Solubility determination of surface-active components from dynamic surface tension data

A new technique of utilizing the dynamic surface tension (ST) data for solubility determination was proposed, tested, and verified in this study. Dibutyl phthalate was chosen as the surface-active component and its solutions were prepared with 0, 1, and 5 wt.% aqueous methanol (MeOH) solutions. The solutions for ST measurement were prepared by stirring the aqueous DBP mixtures in a heated water bath (45 degrees C) for an extended duration of time. The data revealed that an increase in DBP concentration corresponded to a more rapid relaxation of dynamic ST and reached a lower equilibrium ST; similar to that observed amongst typical micelle forming surfactants (at C < cmc). Unlike surfactants, an increase in concentration beyond a certain value corresponded to near-identical relaxations of dynamic ST and the same equilibrium ST. For typical surfactants, although the equilibrium ST remained constant when concentration was increased at C > cmc, the dynamic ST relaxations became increasingly rapid. These inconsistencies in dynamic ST behavior pointed towards the absence of micelle formation amongst the DBP molecules. Based on the dynamic ST data, the solubility of DBP in water, 1 wt.%, and 5 wt.% MeOH(aq) were found to be similar to 6.1, similar to 4.4, and similar to 4.7 (10(-8) mol/cm(3)), respectively.

Removal of tri-(2-chloroisopropyl) phosphate (TCPP) by three types of constructed wetlands

In this study, three types of constructed wetlands (CWs) (biofilm-attachment-surface-CWs, packed bed-CWs and traditional-CWs) were assembled to comparatively evaluate their ability and mechanism to remove tri-(2-chloroisopropyl) phosphate (TCPP) under continuous flow operation. The removal rate (26%-28%) of TCPP in two types of CWs containing plants was twice as much as that in plant-free CWs in 6-month experiments, and TCPP showed a terminal accumulation phenomenon in Cyperus alternifolius with the order of accumulation of leaf>stem>root. The mass balance indicated that the contributions of filler and hydrophyte absorption to TCPP removal were less than 1%, but the transpiration of hydrophytes may make an important contribution (approximately 10%) to TCPP removal. Species in the genera Massilia, Denitratisoma and SM1A02 may be responsible for TCPP biodegradation. In addition, the effect of TCPP on the metabolic pathways and energy generation in the roots of C. alternifolius suggested that TCPP may be transported and utilized through cellular metabolism.

A novel lipase from Aspergillus oryzae WZ007 catalyzed synthesis of brivaracetam intermediate and its enzymatic characterization

Brivaracetam is a structural derivative of the chiral drug levetiracetam and has been approved for the adjuvant treatment of partial epilepsy. As a new antiepileptic drug, it is widely used in a variety of epilepsy models. In this study, a novel lipase M16 derived from Aspergillus oryzae WZ007 was cloned, expressed, and used for chiral resolution. Lipase M16 has a high enantioselectivity to the racemic substrate (R,S)-methyl 2-propylsuccinate 4-tert-butyl ester, and the intermediate (R)-2-propylsuccinic acid 4-tert-butyl ester of brivaracetam was obtained efficiently. Under optimal conditions, the enantiomeric excess of substrate was up to 99.26%, and the e.e.(p) was 96.23%. The conversion and apparent E value were 50.63% and 342.48, respectively. This study suggests a new biocatalytic resolution via lipase M16 for preparing the brivaracetam chiral intermediate and its potential application in the pharmaceutical industry.

Brazilian green propolis promotes the cytoprotective expression of heme oxygenase-1 against oxidative stress injury in murine myoblast cells

Background: Sarcopenia is a progressive skeletal muscle disorder characterized by the progressive loss of muscle mass and function, resulting in physical disability and mortality. Although sarcopenia impacts a large proportion of elderly individuals, no effective treatment for this disease has yet been identified. The excessive production of reactive oxygen species (ROS) can damage tissues and promote aging, and the daily use of dietary antioxidants can be effective for maintaining skeletal muscle health. Propolis, a natural substance that is collected by honey bees, has been used as traditional medicine, and many reports have described its antioxidative properties. However, how propolis exhibits cytoprotective effects and antioxidative effects in skeletal muscles remains unclear. The purpose of this study was to investigate the antioxidative effects of ethanol-extracted Brazilian green propolis (EEBP, from Baccharis dracunculifolia) and its three constituents using an in vitro myoblast cell model. Methods: Murine myoblast C2C12 cells were treated with either EEBP or its constituents, including caffeic acid, trans-ferulic acid, and p-coumaric acid, in the presence of 100 or 300 mM H2O2 to induce oxidative stress injury. The cell death ratio and cell viability were assessed by Hoechst 33342 and propidium iodide staining and the WST-8 assay, respectively. Simultaneously, intracellular ROS production was measured by CM-H2DCFDA [5-(and-6)-chloromethyl-2′,7′-dichlorodihydrofluorescein diacetate, acetyl ester] assay. Finally, immunoblotting was performed in myoblast cell lysates to assess the expression level of an antioxidative enzyme, heme oxygenase-1 (HO-1). Results: We demonstrated that EEBP significantly reduced H2O2-induced cell death at a concentration of 3 mu g/ml in myoblasts. Additionally, caffeic acid at 100 mu M improved cell viability under oxidative stress conditions, but not trans-ferulic acid or p-coumaric acid. Both EEBP and caffeic acid inhibited the H2O2-induced increase in ROS production. Finally, HO-1 expression was increased by treatment with either EEBP or caffeic acid. The increase in HO-1 expression induced by H2O2 was enhanced in the presence of EEBP and caffeic acid. Conclusions: These findings indicated that EEBP has protective effects against oxidative damage in C2C12 murine myoblast cell line. Caffeic acid is an EEBP constituent that contributes to cytoprotective activity. EEBP may act as an inducer of HO-1 to prevent oxidative stress-induced myoblast death.

Convenient method for the synthesis of some novel chiral methyl 2-(2-oxo-2H-benzo[e][1,3]oxazin-3(4H)-yl)propanoate derivatives and biological evaluation of their antioxidant, cytotoxic, and molecular docking properties

Ten chiral methyl 2-(2-oxo-2H-benzo[e][1,3]oxazin-3(4H)-yl)propanoate derivatives 6a-6j have been synthesized from optically pure amino methyl phenol 5 and 4-nitrophenyl chloroformate. These derivatives 6a-6j are characterized by H-1 NMR, C-13 NMR, FT-IR, and HRMS spectral techniques. Optical purity of these derivatives was confirmed by chiral HPLC method. Ten synthesized ester derivatives 6a-6j were screened for their in vitro antioxidant activity. Among the compounds 6b-d and 6h-j have exhibited comparable antioxidant activity with ascorbic acid as a standard. Compounds 6a and 6e-g have shown moderate antioxidant activity. Further, the in vitro cytotoxicity of these compounds were studied through MTT cell proliferation assay in addition the effect on LDH leakage and NO release. Among the derivatives, 6j showed extremely best activity and the IC50 value (12.54 +/- 0.71 mu M) is very close to doxorubicin (7.2 +/- 0.58 mu M) as a standard. Compounds 6b, 6h, and 6i showed better inhibition next to compound 6j on the viability of HepG2 cells with an IC50 value (mu M) of 56.02 +/- 1.4, 41.76 +/- 0.58, and 38.17 +/- 0.34, respectively. Also, molecular docking studies have been carried out with STAT-3 (PDB ID: 1BG1) and BCL-2 (PDB ID: 4AQ3) proteins against the four active compounds 6b, 6h, 6i, and 6j. The binding energies of the tested compounds were in the range of -7.76 to -8.41 kcal/mol, which is very close to doxorubicin (-8.53 kcal/mol) as a standard. These molecular docking results are in good agreement with the in vitro studies.

Modular Synthesis of trans-A(2)B(2)-Porphyrins with Terminal Esters: Systematically Extending the Scope of Linear Linkers for Porphyrin-Based MOFs

Differently functionalized porphyrin linkers represent the key compounds for the syntheses of new porphyrin-based metal-organic frameworks (MOFs), which have gathered great interest within the last two decades. Herein we report the synthesis of a large range of 5,15-bis(4-ethoxycarbonylphenyl)porphyrin derivatives, through Suzuki and Sonogashira cross-coupling reactions of an easily accessible corresponding meso-dibrominated trans-A(2)B(2)-porphyrin with commercially available boronic acids or terminal alkynes. The resulting porphyrins were fully characterized through NMR, MS, and IR spectroscopy and systematically investigated through UV/Vis absorption. Finally, selected structures were saponified to the corresponding carboxylic acids and subsequently proven to be suitable for the synthesis of surface-anchored MOF thin films.
