Discovery of 7,9-Disulfatetrahydroberberine as Novel Lipid-Lowering Agents was written by Li, Dong-Dong;Yu, Pan;Wang, Zhen-Zhong;Xiao, Wei;Zhou, Xin-Hu;Zhao, Lin-Guo. And the article was included in ACS Omega in 2020.Electric Literature of C7H4ClF3O2S This article mentions the following:

Berberine (BBR), a well-known alkaloid, exhibits various pharmacol. activities, especially hypolipidemic activity, which has attracted much interest from medicinal chemists in the past decade. However, little progress was made on the structural modification of BBR for improving lipid-lowering activity, mainly due to its unclear biol. target and low safety. In this study, a new scaffold of 7,9-disulfatetrahydroberberine was discovered unexpectedly, provided with extremely low cytotoxicity. Hence, a novel series of highly safe 7,9-disulfatetrahydroberberines were designed, synthesized, and evaluated for their hypolipidemic activities. In order to investigate the significance of the 9-position substituent, another new series of 7-sulfatetrahydroberberines were designed and synthesized. Lipid-lowering experiments showed that among these compounds, 5f exhibited the best lipid-lowering activity based on two cell models, 3T3-L1 cells and HepG2 cells. Compared with the blank control, the inhibition rate of compound 5f against total cholesterol was over 60%, the inhibition rate against triglyceride was over 70%, the inhibition rate against low-d. lipoprotein cholesterol was approx. 75%, and the inhibition rate against high-d. lipoprotein cholesterol was close to 50%, which were far superior to the pos. control BBR. This result also verified the feasibility of the development of BBR as a lipid-lowering drug via disubstituted modification at the 7- and 9-position. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Electric Literature of C7H4ClF3O2S).

3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6) 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. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Electric Literature of C7H4ClF3O2S

Metabolic fate of environmental chemical triclocarban in colon tissues: roles of gut microbiota involved was written by Wang, Guangqiang;Zhang, Hongna;Zhang, Jianan;Sanidad, Katherine Z.;Yeliseyev, Vladimir;Parsonnet, Julie;Haggerty, Thomas D.;Yang, Haixia;Ai, Lianzhong;Xie, Minhao;Cai, Zongwei;Zhang, Guodong. And the article was included in Science of the Total Environment in 2021.Recommanded Product: 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea This article mentions the following:

Metabolic transformations play critical roles in the bioavailability and toxicities of environmental pollutants and toxicants. However, most previous research has focused on the metabolic reactions in host tissues, the gut microbiota-mediated biotransformation of environmental compounds is understudied. Using triclocarban (TCC) as a model environmental compound, here we study the metabolic fate of TCC in gut tissues and determine the roles of gut microbiota involved. We find that compared with other tissues, the colon tissue has a unique metabolic profile of TCC, with high abundance of the parent compound TCC and its free-form metabolites. Using a variety of approaches including antibiotic-mediated suppression of gut bacteria in vivo, germ-free mice, and in vitro culture of fecal bacteria, we found that the unique metabolic profile of TCC in the colon is mediated by the actions of gut microbiota. Overall, our findings support that gut microbiota plays important roles in colonic metabolism of TCC, highlighting the importance to consider the contributions of gut microbiota in toxicol. evaluation of environmental compounds In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Recommanded Product: 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea).

Anisotropic Ferromagnetic Organic Nanoflowers was written by Sasidharan, Sajitha;Ghosh, Sayandeep;Sreedhar, Rishi;Kumari, Kalpana;Thota, Subhash;Ramakrishnan, Vibin. And the article was included in Journal of Physical Chemistry C in 2022.Application In Synthesis of (Chloromethanetriyl)tribenzene This article mentions the following:

We report a weak anisotropic ferromagnetic behavior in a purely organic mol. at room temperature, a property rarely reported in organic nanomaterials. The reported 1,2-bis(tritylthio)ethane, forming plate- and organic-flower-like morphologies at the nanolevel, is the first organic crystal with an inherent magnetic property at 300 and 2 K. However, at low temperatures, the magnetization value [M_max(T) ~116 emu/mol at 2 K] increases drastically at 3 orders higher compared to 300 K. Interestingly, the system exhibits strong anisotropy with an anisotropic constant, K₁ ~3.25 x 10³ erg/cc, and anisotropy field, H_K ~3.25 kOe. Below 10 K, this system displays unusual temperature dependence of the coercive field [H_C(T)] and remanence magnetization [M_R(T)] with a hysteresis-peak anomaly (T* ~10-15 K) due to the enhanced spin-orbit coupling. The maximum H_C and M_R at T* were H_C = 220 Oe and M_R ~12 emu/mol, resp. Beyond T*, H_C(T) and M_R(T) drop continuously and become negligible as the measurement temperature approaches 300 K. Our results demonstrate that the tri-Ph mols. can be further exploited for the design and synthesis of organic magnets for possible applications in spintronics and memory storage devices. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Application In Synthesis of (Chloromethanetriyl)tribenzene).

(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

And the article was included in Chemistry & Biodiversity in 2021.HPLC of Formula: 3386-33-2 This article mentions the following:

Essential oils (EOs) are a promising group of natural products of the aromatic plants due to their various biol. effects such as allelopathic, antioxidant, antimicrobial activities. The present study aimed to construct the detailed chem. profile of the EO derived from Deverra tortuosa aerial parts along with assessing its allelopathic, antimicrobial, and antioxidant potentialities. The EO was extracted by hydrodistillation and analyzed via gas chromatog.-mass spectrometry (GC/MS). The allelopathic activity of the EO was assessed against the germination and seedling growth of the weed Chenopodium murale. Also, the EO was tested against five microbes. The antioxidant activity was determined using the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). The GC/MS anal. of EO revealed the presence of 86 compounds with a preponderance of oxygenated sesquiterpenes and monoterpene hydrocarbons. Widdrol, β-phellandrene, piperitol, cubedol, α-terpinene, (E)-10-heptadecen-8-ynoic acid Me ester, citronellyl tiglate, and m-cymene were the major compounds A comparative profile was established between the EOs constituents of our study with the documented EOs of D. tortuosa and the other Deverra species around the world via agglomerative hierarchical clustering (AHC) and principal components anal. (PCA). The EO showed a substantial allelopathic activity against C. murale, as well as it showed considerable antimicrobial and antioxidant activities. Thereby, the EO of D. tortuosa could be considered as a promising environmental-friendly bioherbicide against weeds. Also, it could be integrated into food preservation due to its potent antimicrobial and antioxidant activities. However, further study is recommended for more characterization of the major compounds and evaluation of their activities, either singular or synergistic, and assess their efficiency and biosafety.
