Jian, Tongtong published the artcileMetabolomic comparison between natural Huaier and artificial cultured Huaier, SDS of cas: 103-26-4, the publication is Biomedical Chromatography (2022), 36(6), e5355, database is CAplus and MEDLINE.

Vanderbylia robiniophila (Murrill) B. K. (Huaier) is a kind of higher fungal fruiting body that is parasitic on the trunk of Sophora japonica and Robinia pseudoacacia L.. As a traditional Chinese medicine with a history of more than 1,600 years, Huaier has attracted wide attention for its excellent anticancer activity. A systematic study on the metabolome differences between natural Huaier and artificial cultured Huaier was conducted using liquid chromatog.-mass spectrometry in this study. Principal component anal. and orthogonal projection on latent structure-discriminant anal. results showed that cultured Huaier evidently separated and individually separated from natural Huaier, indicating metabolome differences between natural and cultured Huaier. Hierarchical clustering anal. was further performed to cluster the differential metabolites and samples based on their metabolic similarity. The higher contents of amino acids, alkaloids and terpenoids in natural Huaier make it an excellent choice as a traditional Chinese medicine for anticancer or nutritional supplementation. The results of the Bel-7,402 and A549 cell cytotoxicity tests showed that the anticancer activity of natural Huaier was better than that of cultured Huaier. This may be due to the difference in chem. composition, which makes the anticancer activities of natural and cultured Huaier different.

Wu, Guolong published the artcileExtraction and separation of yttrium from other rare earths in chloride medium by phosphorylcarboxylic acids, HPLC of Formula: 103-26-4, the publication is Journal of Rare Earths (2022), 40(6), 958-964, database is CAplus.

Two phosphorylcarboxylic acids, 3-((bis(2-ethylhexyloxy))phosphoryl)propanoic acid (PPA) and 3-((bis(2-ethylhexyloxy))phosphoryl)-3-phenylpropanoic acid (PPPA), were synthesized for separating yttrium from other rare earths in the chloride feed of ion-adsorption type rare earth concentrate The effect of the factors such as pH_1/2, temperature, saponification degree and phase modifiers was investigated. The separation efficiencies of PPA and PPPA are obviously better than the typical extractants such as sec-octylphenoxy acetic acid (CA-12) and naphthenic acid (NA). The extraction process of rare earths by PPA and PPPA is a cation exchanging reaction, which is similar to those of CA-12 and NA. The loaded rare earths in both PPA and PPPA systems can be effectively back-extracted by 0.5 mol/L HCl or higher concentration A cascade extraction process for separating yttrium from other rare earths was developed using PPPA as the extractant. The yttrium product with the purity of 97.20 wt% was obtained by 35 stages of extraction and 12 stages of scrubbing.

Sobhani, Sara published the artcileA new nanomagnetic Pd-Co bimetallic alloy as catalyst in the Mizoroki-Heck and Buchwald-Hartwig amination reactions in aqueous media, Application of Methyl 3-phenyl-2-propenoate, the publication is Scientific Reports (2021), 11(1), 17025, database is CAplus and MEDLINE.

A Pd-Co bimetallic alloy encapsulated in melamine-based dendrimer supported on magnetic nanoparticles denoted as γ-Fe₂O₃@MBD/Pd-Co was synthesized by a facile co-complexation-reduction method and characterized sufficiently. The catalytic evaluation of γ-Fe₂O₃@MBD/Pd-Co showed promising results in the Mizoroki-Heck and Buchwald-Hartwig amination reactions of various iodo-, bromo- and challenging chloroarenes in aqueous media. The synergetic cooperative effect of both Pd and Co and dispersion of the catalyst in water due to the encapsulation of γ-Fe₂O₃ by melamine-based dendrimer lead to high catalytic performance compared with the monometallic counterparts. The dispersion of the magnetic catalyst also facilitates the recovery and reuse of the catalyst by ten consecutive extraction and final magnetic isolation with no loss of catalytic activity, keeping its structure unaltered.

Zhang, Li published the artcileSynthesis of yolk-shell magnetic porous organic nanospheres supported Pd catalyst for oxidation of alcohols and Heck reactions, Synthetic Route of 103-26-4, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2021), 130237, database is CAplus.

Yolk-shell magnetic porous organic nanospheres (MPONs) supported Pd nanoparticles (Pd@MPONs) were synthesized by encapsulating Fe₃O₄ and Pd nanoparticles in one cavity of hollow porous organic nanospheres (HPONs) using a continuous “ship-in-bottle” strategy. The obtained Pd@MPONs possessed a hierarchically micro/mesoporous structure, high surface area (354 m²/g) and displayed excellent magnetic response (9 emu/g). They showed high catalytic performance in the oxidation of alcs. under mild conditions and the Heck-Mizoroki reaction, and brilliant magnetic recyclability, they can be removed rapidly from a reaction system using external magnetic fields without any catalytic activity decrease. Hence, the Pd@MPONs are easily recoverable nanocatalysts which have practical significance in the future sustainable industry.

Yao, Xiang published the artcilePreparation of cinnamon hydroxamic acid and its flotation characteristics and mechanism to fine-grained wolframite, Name: Methyl 3-phenyl-2-propenoate, the publication is Journal of Molecular Liquids (2022), 119721, database is CAplus.

A new collector-cinnamon hydroxamic acid (CIHA)-was synthesized from Me cinnamate using the hydroxyamine method. The results of single-mineral flotation and artificially mixed-mineral flotation indicated that CIHA had good collection performance and selectivity. Adsorption-capacity test results indicated that the CIHA collector adsorbed wolframite and quartz, and the adsorption intensity of wolframite was higher than that of quartz. The adsorption mechanism was investigated via zeta-potential anal., Fourier transform IR spectroscopy, and XPS. The results indicated that CIHA interacted with Mn on the wolframite surface via Pb²⁺ activation to form a surface Mn-O-Pb²⁺ complex, which formed a new Fe-O bond with Fe. Hydroxamic acid may have formed a five-element chelated hydroxamic group with the metal on the wolframite surface. The hydrophobicity of the wolframite surface was improved, making the wolframite more easily attach to bubbles and be more easily carried to the pulp surface.

Yang, Lishou published the artcileSynthesis of novel 1-phenyl-benzopyrrolizidin-3-one derivatives and evaluation of their cytoneuroprotective effects against NMDA-induced injury in PC12 cells, HPLC of Formula: 103-26-4, the publication is Bioorganic & Medicinal Chemistry (2022), 116675, database is CAplus and MEDLINE.

A range of novel 1-phenyl-benzopyrrolizidin-3-one derivatives I (R¹ = Ph, 2-MeOC₆H₄, 3-BnOC₆H₄, etc.; R² = H, 8-F, 7-OBn) were synthesized and evaluated for neuroprotective effects against N-methyl-D-aspartate (NMDA)-induced injury in PC12 cells. Interestingly, derivatives that 1-Ph moiety bearing electron-donating group, especially benzyloxy, and the trans-forms exhibited better protective activity against NMDA-induced neurotoxicity. Compound I (R¹ = 3-BnOC₆H₄; R² = 8-F) demonstrated the best neuroprotective potency and shown a dose-dependent prevention. The increased intracellular calcium (Ca²⁺) influx caused by NMDA in PC12 cells was reversed in the case of compound I (R¹ = 3-BnOC₆H₄; R² = 8-F) pretreatment at 15μM. These results suggested that the synthesized 1-phenyl-benzopyrrolizidin-3-one derivatives exerted neuroprotective effect on NMDA-induced excitotoxicity in PC12 cells associated with inhibition of Ca²⁺ overload and can be further optimized for the development of neuroprotective agents.

Wang, Nan published the artcileAltered fecal metabolomics and potential biomarkers of psoriatic arthritis differing from rheumatoid arthritis, Recommanded Product: Methyl 3-phenyl-2-propenoate, the publication is Frontiers in Immunology (2022), 812996, database is CAplus and MEDLINE.

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease, and the diagnosis is quite difficult due to the unavailability of reliable clin. markers. This study aimed to investigate the fecal metabolites in PsA by comparison with rheumatoid arthritis (RA), and to identify potential diagnostic biomarkers for PsA. The metabolic profiles of the fecal samples from 27 PsA and 29 RA patients and also 36 healthy controls (HCs) were performed on ultrahigh- performance liquid chromatog. coupled with hybrid triple quadrupole time-offlight mass spectrometry (UHPLC-Q-TOF-MS). And differentially altered metabolites were screened and assessed using multivariate anal. for exploring the potential biomarkers of PsA. The results showed that 154 fecal metabolites were significantly altered in PsA patients when compared with HCs, and 45 metabolites were different when compared with RA patients. A total of 14 common differential metabolites could be defined as candidate biomarkers. Furthermore, a support vector machines (SVM) model was performed to distinguish PsA from RA patients and HCs, and 5 fecal metabolites, namely, α/β-turmerone, glycerol 1-hexadecanoate, dihydrosphingosine, pantothenic acid and glutamine, were determined as biomarkers for PsA. Through the metabolic pathways anal., we found that the abnormality of amino acid metabolism, bile acid metabolism and lipid metabolism might contribute to the occurrence and development of PsA. In summary, our research provided ideas for the early diagnosis and treatment of PsA by identifying fecal biomarkers and analyzing metabolic pathways.
