[Objective] To establish rapid anal. method for the volatile components in FOLIUM ARTEMISIA ARGYI, and to research the contents and distribution characteristics of volatile components in FOLIUM ARTEMISIA ARGYI grown in different areas. [Methods] Volatile components in FOLIUM ARTEMISIA ARGYI were analyzed by HS-SPME/GC-MS. Relative content of each component was calculated by peak area normalization method. Data were analyzed by principal component anal. and duster anal. [Results] A total of 84 chem. components were preliminarily identified, which were mainly the ketones, alkenes and alcs. There were certain differences in the volatile components of FOLIUM ARTEMISIA ARGYI. Principal component anal. and cluster anal. could effectively isolate the FOLIUM ARTEMISIA ARGYI gown in different areas. [Conclusions] This method was stable and reliable, which could be used for the rapid anal. of the volatile components in FOLIUM ARTEMISLA ARGYI, and provided certain scientific references for the quality evaluation of the volatile components in FOLIUM ARTEMISIA ARGYI. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Reference of 3386-33-2).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Reference of 3386-33-2

And the article was included in Macromolecular Chemistry and Physics in 2022.Category: chlorides-buliding-blocks This article mentions the following:

The pursuit of highly permeable thin-film nanocomposite (TFNC) nanofiltration (NF) membranes with desirable selectivity is an eternal topic for desalination and wastewater treatment. Herein, a facile route to engineer polyamide (PA) NF membranes is reported with a coral-reef-like thin PA active layer atop a polydopamine pre-decorated ethylene vinyl alc. copolymer (EVOH) nanofiber scaffold (EVOH-PDA) via interfacial polymerization (IP). EVOH-PDA possesses a submicron pore size and super-hydrophilic surface, which provides abundant thin water layers covering nanofibers in the IP process resulting in the PA layer with a morphol. of coral-reef-like highland surrounded by flat low-lying regions. The resultant NF membrane presents high permeance of 32.19 L m^-2h^-1bar^-1 and high rejection of 96.52% to 1000 ppm Na₂SO₄ feed solution with a stable performance against operation time and high salt concentration This work provides a new approach to fabricating PA TFNC membranes with outstanding NF performance in liquid separation applications. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Category: chlorides-buliding-blocks).

Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Category: chlorides-buliding-blocks

Two-dimensional z-type MoS₂/g-C₃N₄ semiconductor heterojunction nanocomposites for industrial methylene blue dye degradation under daylight was written by Sivakumar, S.;Daniel Thangadurai, T.;Manjubaashini, N.;Nataraj, D.. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Related Products of 61-73-4 This article mentions the following:

The photocatalytic degradation of textile dyes by graphitic carbon nitrides (g-C₃N₄) under sunlight has received increased attention. Nevertheless, the photocatalytic application of g-C₃N₄ is still limited by its faster charge carrier recombination. To overcome this obstacle, this research has used an impregnation approach to deposit thin-layered molybdenum disulfide (MoS₂) on g-C₃N₄. The crystallinity, morphol., chem. composition, and structural defects of the resulting two-dimensional (2D) z-type MoS₂/g-C₃N₄ semiconductor heterojunction nanocomposite were investigated by XRD, SEM, EDAX, HRTEM, XPS, Raman, and FT-IR techniques. The microscopic images clearly show that (i) g-C₃N₄ is densely covered by MoS₂, and (ii) the g-C₃N₄ and MoS2 interface. Using industrial dye, Methylene Blue (MB), the photocatalytic degradation competency of 5% MoS₂/g-C₃N₄ and 10% MoS₂/g-C₃N₄ nanocomposites was examined under natural sunlight. The homogeneous distribution of the MoS₂ layer on the g-C₃N₄ surface helps significantly to reduce the charge carrier recombination during the photocatalytic process. The Mott-Schottky and impedance measurements demonstrate a more active site for photogenerated electron-hole pair and efficient charge separation for enhanced photocatalytic process, which is consistent with the optical property results. Based on the findings, we confirm that the as-prepared MoS₂/g-C₃N₄ nanocomposites outperformed bare MoS₂ and g-C₃N₄ in terms of MB degradation (100%). In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Related Products of 61-73-4).

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides.

Synthesis and properties of stearylhexylmethyl carboxyl betaine was written by Song, Hong-juan;Song, Bing-lei;Cui, Zheng-gang;Xu, Li-jun. And the article was included in Jingxi Huagong in 2015.Safety of 1-Chlorooctadecane This article mentions the following:

In order to gain insights into the effects of mol. structure on the properties of surfactants, an asym. double long-chain alkyl betaine, stearylhexylmethyl carboxyl betaine (C₁₈₊₆B), was synthesized using stearic acid and hexanoic acid as starting materials and its surface activity was measured and compared with that of didodecyl Me carboxyl betaine (diC₁₂B), a sym. double long-chain betaine with equal total carbon number The results showed that C₁₈₊₆B had a surface activity similar to that of diC₁₂B in general, but displays an aqueous solubility much better than that of diC₁₂B. As a surfactant for surfactant-polymer flooding free of alkali, C₁₈₊₆B seemed to be slightly less hydrophobic against Daqing crude oil, which solely could reduce the Daqing crude oil/connate water interfacial tension (IFT) to 10^-2 mN/m magnitude and gave a saturated adsorption 30% lower than that of diC₁₂B at Daqing sandstone/water interface at 45°C. C₁₈₊₆B solely could reduce C₇-C₉ n-alkanes/connate water IFT to 10^-3 mN/m magnitude at 45°C, and could reduce the Daqing crude oil/connate water IFT to 10^-3 mN/m magnitude at 45°C by mixing with the more hydrophobic surfactant diC₁₂B and other hydrophilic betaine surfactant, where the aqueous solubility of the formulation was greatly improved by the presence of C₁₈₊₆B. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Safety of 1-Chlorooctadecane).

The asym. unit of the title compound, [Ir(C₉H₇)(C₂H₄)₂], consists of two independent mols. crystallog. data and at. coordinates are given. The bonding between Ir and the five-membered ring of the indenyl ligand shows the usual asymmetry associated with the typical ring slippage responsible for the enhanced activity of indenyl metal compounds when compared with the analogous cyclopentadienyl metal compound There are three short Ir-C bonds of 2.210(3), 2.190(4) and 2.220(3) Å and two long Ir-C bonds to the C atoms that are part of the fused six-membered ring of 2.349(4) and 2.366(3) Å for one of the independent mols. [2.208(4), 2.222(3), 2.197(4) Å for the short distances and 2.371(3) and 2.358(3) Å for the long distances in the 2nd mol.]. This results in both indenyl ligands being slightly kinked, with dihedral angles of 6.8(4)° and 6.5(4)°.

Fragment-growing guided design of Keap1-Nrf2 protein-protein interaction inhibitors for targeting myocarditis was written by Meng, Ning;Tang, Hua;Zhang, Hao;Jiang, Chengshi;Su, Li;Min, Xiao;Zhang, Wannian;Zhang, Hua;Miao, Zhenyuan;Zhang, Wen;Zhuang, Chunlin. And the article was included in Free Radical Biology & Medicine in 2018.Electric Literature of C7H4ClF3O2S This article mentions the following:

Small-mol. inhibitors that block the Keap1-Nrf2 protein-protein interactions are being intensely pursued as a new therapeutic strategy for oxidative stress-related diseases, such as cancer, diabetes, Alzheimer’s disease, arteriosclerosis, inflammation and myocarditis. However, there are not enough studies on antioxidant treatments using small mols. in myocarditis. The authors herein provided a series of novel hydronaphthoquinones as the Keap1-Nrf2 interaction inhibitors targeting LPS-induced myocarditis both in vitro and in vivo. These compounds were designed through an in-silico fragment growing approach based on the previous reported compound The new compounds were predicted to form addnl. hydrogen bonds with the S363 residue, leading to higher inhibitory activity. Among these new derivatives, compounds I and II emerged as inhibitors with significant biochem. potency, as determined by fluorescent anisotropy assay and confirmed by surface plasmon resonance (SPR) and differential scanning fluorometry (DSF) assays. These inhibitors can dose-dependently protect the H9c2 cardiac cells against LPS-induced injury (100% at 2 μM and 4 μM) and effectively prolong survival or save the life of LPS-injured mice. Mechanistic studies showed that these inhibitors could release Nrf2 in H9c2 cells and LPS-inflammatory mouse models and translocate into the nucleus in a dose-response manner, which significantly increased the downstream genes (HO-1, NQO-1) and the pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), while ROS production dramatically decreased. Their protective effects and the mechanism of action were further confirmed by siNrf2 transfected experiment Collectively, the novel hydronaphthoquinones can be used as promising lead compounds for the study of Keap1-Nrf2 protein-protein interactions and further antimyocarditis drug development. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Electric Literature of C7H4ClF3O2S).

Determining the excited-state substituent constants of furyl and thienyl groups was written by Qu, Junyan;Cao, Chao-Tun;Cao, Chenzhong. And the article was included in Journal of Physical Organic Chemistry in 2018.Electric Literature of C8H9Cl This article mentions the following:

Six series of styrene derivatives XCH=CHArY (total of 65) containing the styrene parent mol. skeleton were synthesized (here, Y is OMe, Me, H, F, Cl, CF₃, CN, and NO₂, and X is 2-furyl, 3-furyl, 2′-methyl-2-furyl, 2-thienyl, 3-thienyl, and 2′-methyl-2-thienyl). Their UV absorption spectra were measured in anhydrous ethanol, and their wavelength of absorption maximum λ_max was recorded. For the wavenumber ν_max (cm^-1, ν_max = 1/λ_max) of the obtained λ_max, a quant. correlation anal. was performed, and 6 excited-state substituent constants σCCpex of groups X were obtained by means of curve-fitting method. Taking the ν_max values of total 90 compounds of styrene derivatives as a data set (including 25 compounds from reference and 65 compounds of this work), a quant. correlation anal. was performed, and the reliability of the obtained σCCpex was verified. In addition, 12 samples of disubstituted Schiff bases (XCH=NArY) involving the above groups X were synthesized, and their ν_max values were recorded. Using these 12 ν_max together with the 14 ν_max values of Schiff bases taken from reference (total of 26 compounds), it was further verified that the σCCpex values are reliable by means of quant. correlation method. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Electric Literature of C8H9Cl).

1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Electric Literature of C8H9Cl
