Liu, Chong; Sun, Dan; Zheng, Hong-Xiang; Wang, Guo-Bao; Liu, Wen-Shen; Cao, Yue; Tang, Ye-Tao; Qiu, Rong-Liang published the artcile< The limited exclusion and efficient translocation mediated by organic acids contribute to rare earth element hyperaccumulation in Phytolacca americana>, Reference of 112-63-0, the main research area is Phytolacca rare earth element translocation organic acid; Hyperaccumulator; Rhizosphere; Root exudate; Translocation; Yttrium.

Organic acids play an important role in metal tolerance, uptake, and translocation in hyperaccumulators. Phytolacca americana is a rare earth element (REE) hyperaccumulator, but the underlying mechanisms on REE tolerance and accumulation mediated by organic acids are poorly understood. Here, we reported for the first time the strategy of P. americana to enhance REE tolerance and accumulation through organic acids from root external secretion to internal biosynthesis. Different from the exclusion of heavy metal by organic acid in the typical plants, the results showed that oxalate secretion (0.3-0.6μmol h-1 g-1 root DW) induced by yttrium (Y) could not prevent Y from entering the roots, resulting in excess Y uptake by P. americana. Yttrium stress also stimulated the accumulation of malate and citrate by 1.4- and 2.0-folds in the root cortex. Exogenous malate and citrate promoted the redistribution of Y from the root cell walls to the shoot by 30% and 21%, resp. Based on comparative transcriptome anal., 6-fold up-regulation was observed in PaNIP1;2, whose homol. AtNIP1;2 is responsible for the transport of Al-malate in Arabidopsis. These results suggested that the promoted formation of Y-malate complexes within the roots potentially accelerated the transport of Y from P. americana roots to shoots through PaNIP1;2. Our study revealed the potential mechanism of organic acids in the external exclusion and internal detoxification and translocation of REE in P. americana roots, which provided a basis for improving the efficiency of REE phytoextraction

Potikha, L. M.; Kovtunenko, V. A.; Kisil, V. M. published the artcile< Condensed isoquinolines. Part 21. Condensation of o-bromomethylphenylacetonitrile with substituted anthranilic acids>, Formula: C19H34O2, the main research area is bromomethylbenzeneacetonitrile anthranilate cyclocondensation; isoquinoquinazolinone hydro preparation tautomerism.

The reaction of substituted anthranilic acids and esters with ortho-bromomethylphenylacetonitrile gives 2,3-disubstituted 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-one hydrobromides. It was found that 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-ones can exist in the two tautomeric imine and enamine forms. The tautomeric equilibrium position depends on the nature and position of the substituent in the quinazoline fragment. The borohydride reduction, oxidation, and reaction of the 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-ones with electrophilic reagents was studied.

Pulvirenti, Luca; Monforte, Francesca; Lo Presti, Francesca; Li Volti, Giovanni; Carota, Giuseppe; Sinatra, Fulvia; Bongiorno, Corrado; Mannino, Giovanni; Cambria, Maria Teresa; Condorelli, Guglielmo Guido published the artcile< Synthesis of MIL-Modified Fe3O4 Magnetic Nanoparticles for Enhancing Uptake and Efficiency of Temozolomide in Glioblastoma Treatment>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is enhancing Uptake Efficiency temozolomide Glioblastoma Treatment; Fe3O4; glioblastoma; magnetic nanoparticles; metal organic frameworks; temozolomide.

A nanometric hybrid system consisting of a Fe3O4 magnetic nanoparticles modified through the growth of Fe-based Metal-organic frameworks of the MIL (Materials Institute Lavoiser) was developed. The obtained system retains both the nanometer dimensions and the magnetic properties of the Fe3O4 nanoparticles and possesses increased the loading capability due to the highly porous Fe-MIL. It was tested to load, carry and release temozolomide (TMZ) for the treatment of glioblastoma multiforme one of the most aggressive and deadly human cancers. The chem. characterization of the hybrid system was performed through various complementary techniques: X-ray-diffraction, thermogravimetric anal., FT-IR and X-ray photoelectron spectroscopies. The nanomaterial showed low toxicity and an increased adsorption capacity compared to bare Fe3O4 magnetic nanoparticles (MNPs). It can load about 12 mg/g of TMZ and carry the drug into A172 cells without degradation Our exptl. data confirm that, after 48 h of treatment, the TMZ-loaded hybrid nanoparticles (15 and 20μg/mL) suppressed human glioblastoma cell viability much more effectively than the free drug. Finally, we found that the internalization of the MIL-modified system is more evident than bare MNPs at all the used concentrations both in the cytoplasm and in the nucleus suggesting that it can be capable of overcoming the blood-brain barrier and targeting brain tumors. In conclusion, these results indicate that this combined nanoparticle represents a highly promising drug delivery system for TMZ targeting into cancer cells.

A highly chemo- and enantioselective hydrogenation of β-diketones was achieved by using [Ru(benzene)(S)-SunPhosCl]Cl for consistency in THF. The neighboring heteroatoms played important roles in guaranteeing the reactivity and controlling the chemoselectivity. These results suggested a potential approach for the clean and facile synthesis of functionalized chiral β-hydroxy ketones, which could otherwise be prepared through much less step-economic transformations.

Solvated Li+ ions are intercalated into graphite in a dilute glyme-based solution and this reaction has attracted much attention for use in advanced lithium-ion batteries due to their high rate capability. In this study, Li+ co-intercalation behaviors in asym. glymes (CH3O(CH2CH2O)nC4H9, n = 2 or 3) were investigated and compared to those in sym. glymes (CH3O(CH2CH2O)nCH3, n = 1-4). Despite the large alkyl sidechains of asym. glymes, co-intercalation reactions of solvated Li+ proceeded as well as those in sym. glymes. In charge and discharge measurements, the reversible capacities in asym. glyme-based solutions were smaller than those in sym. glymes except for tetraglyme, which showed the lowest reversible capacity. There was no clear difference in the sandwich distances of glyme-Li-GICs calculated from X-ray diffraction patterns of both sym. and asym. glymes. Therefore, solvated Li+ ions with asym. glymes occupied more space in the graphite interlayer compared to sym. glymes, which resulted in smaller reversible capacities for asym. glymes. These results demonstrate the influence of solvent-related structures of GICs on reversible capacities for co-intercalation systems.

Shiraishi, Takaya; Sakaitani, Masahiro; Otsuguro, Satoko; Maenaka, Katsumi; Suzuki, Toshiharu; Nakaya, Tadashi published the artcile< Novel Notch signaling inhibitor NSI-1 suppresses nuclear translocation of the Notch intracellular domain>, COA of Formula: C19H34O2, the main research area is novel notch signaling inhibitor NSI nuclear translocation intracellular domain.

The Notch receptor serves a fundamental role in the regulation of cell fate determination through intracellular signal transmission. Mutation of the Notch receptor results in abnormal active signaling, leading to the development of diseases involving abnormal cell growth, including malignant tumors. Therefore, the Notch signaling pathway is a useful pharmacol. target for the treatment of cancer. In the present study, a compound screening system was designed to identify inhibitors of the Notch signaling targeting Notch intracellular domain (NICD). A total of 9,600 compounds were analyzed using the Michigan Cancer Foundation-7 (MCF7) human breast adenocarcinoma cell line and the SH-SY5Y human neuroblastoma cell line with the reporter assay system using an artificial protein encoding a partial Notch carboxyl-terminal fragment fused to the Gal4 DNA-binding domain. The mol. mechanism underlying the inhibition of Notch signaling by a hit compound was further validated using biochem. and cell biol. approaches. Using the screening system, a potential candidate, Notch signaling inhibitor-1 (NSI-1), was isolated which showed 50% inhibition at 6.1μM in an exogenous Notch signaling system. In addition, NSI-1 suppressed the nuclear translocation of NICD and endogenous gene expression of hairy and enhancer of split-1, indicating that NSI-1 specifically targets Notch. Notably, NSI-1 suppressed the cell viability of MCF7 cells and another human breast adenocarcinoma cell line, MDA-MB-231 exhibiting constitutive and high Notch signaling activity, whereas no significant effect was observed in the SH-SY5Y cells bearing a lower Notch signaling activity. NSI-1 significantly suppressed the viability of SH-SY5Y cells expressing exogenous human Notch1. These results indicate that NSI-1 is a novel Notch signaling inhibitor and suggest its potential as a useful drug for the treatment of diseases induced by constitutively active Notch signaling.

Lee, Hyojin; Jang, Kyoung Won published the artcile< Effect of puffing in the extraction of active ingredients from the roots of Paeonia lactiflora and Astragalus membranaceus>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is Paeonia Astragalus puffing root polyphenol.

In Asia, the roots of Paeonia lactiflora and Astragalus membranaceus have been used as therapeutic agents for thousands of years. Once the medicinal plants are harvested, they are dried and their ingredients are extracted by heat-mediated reflux extraction However, the condensed structure of organic products (especially roots) limits the extraction of bioactive components. In this study, we assessed the effect of the puffing method (using high temperature and pressure) before the extraction process in relation to the profile and antioxidant capacity of active ingredients. We demonstrated that the addnl. puffing process before extraction methods improves the yield of polyphenol concentrations and antioxidant activities from the roots of P. lactiflora and A.membranaceus.

Wang, Fujing; Fan, Jiaer; Pei, Tingting; He, Zhuoen; Zhang, Jiaxing; Ju, Liliang; Han, Zhongxiao; Wang, Mingqing; Xiao, Wei published the artcile< Effects of shenkang pills on early-stage diabetic nephropathy in db/db mice via inhibiting AURKB/ RacGAP1/RhoA signaling pathway>, Product Details of C19H34O2, the main research area is shenkang nephroprotective agent AURKB RacGAP1 RhoA diabetic nephropathy; AURKB; LC/MS; RacGAP1; RhoA; diabetic nephropathy; shenkang pills; transcriptome.

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease, so there is an urgent need to suppress its development at early stage. Shenkang pills (SKP) are a hospital prescription selected and optimized from effective traditional Chinese medicinal formulas for clin. treatment of DN. In the present study, liquid chromatog.-quadrupole-time of flight-mass spectrometry (LC-Q-TOF-MS) and total contents qualification were applied to generate a quality control standard of SKP. For verifying the therapeutic effects of SKP, db/db mice were administered intragastrically with SKP at a human-equivalent dose (1.82 g/kg) for 4 wk. Moreover, the underlying mechanism of SKP were analyzed by the renal RNA sequencing and network pharmacol. LC-Q-TOF-MS identified 46 compounds in SKP. The total polysaccharide and organic acid content in SKP were 4.60 and 0.11 mg/mL, resp., while the total flavonoid, saponin, and protein content were 0.25, 0.31, and 0.42 mg/mL, resp. Treatment of SKP significantly reduced fasting blood glucose, improved renal function, and ameliorated glomerulosclerosis and focal foot processes effacement in db/db mice. In addition, SKP protected podocytes from injury by increasing nephrin and podocin expression. Furthermore, transcriptome analyses revealed that 430 and 288 genes were up and down-regulated in mice treated with SKP, relative to untreated controls. Gene ontol. enrichment anal. revealed that the differentially expressed genes mainly involved in modulation of cell division and chromosome segregation. Weighted gene co-expression network anal. and network pharmacol. anal. indicated that aurora kinase B (AURKB), Rac GTPase activating protein 1 (RacGAP1) and SHC binding, and spindle associated 1 (shcbp1) might be the core targets of SKP. This protein and Ras homolog family member A (RhoA) were found overexpression in db/db mice, but significantly decreased with SKP treatment. We conclude that SKP can effectively treat early-stage DN and improve renal podocyte dysfunction. The mechanism may involve down-regulation of the AURKB/RacGAP1/ RhoA pathway.
