Related Products of 39637-74-6《A Bioinspired Synthesis of (±)-Rubrobramide, (±)-Flavipucine, and (±)-Isoflavipucine》 was published in 2016. The authors were Mizutani, Shoma;Komori, Kenta;Taniguchi, Tohru;Monde, Kenji;Kuramochi, Kouji;Tsubaki, Kazunori, and the article was included in《Angewandte Chemie, International Edition》. The author mentioned the following in the article:

A biomimetic synthesis of naturally occurring lactams rubrobramide, flavipucine, and isoflavipucine is described. The key step is a regioselective Darzens reaction between iso-Bu glyoxal and an α-bromo-β-ketoamide. The construction of the core tricyclic ring system of rubrobramide was achieved by a cascade reaction in a single step from an α,β-epoxy-γ-lactam. Furthermore, the absolute configuration of naturally occurring (+)-rubrobramide was determined by vibrational CD. (±)-Flavipucine and (±)-isoflavipucine were synthesized from an epoxyimide, which was prepared by reaction of iso-Bu glyoxal with a protected α-bromo-β-ketoamide. Deprotection of the epoxyimide and formation of the pyridone ring gave (±)-flavipucine, which was converted into (±)-isoflavipucine by thermal isomerization. And (1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) was used in the research process.

Synthetic Route of C15H17ClFNO4S《Astaxanthin protects against early acute kidney injury in severely burned rats by inactivating the TLR4/MyD88/NF-κB axis and upregulating heme oxygenase-1》 was published in 2021. The authors were Guo, Songxue;Guo, Linsen;Fang, Quan;Yu, Meirong;Zhang, Liping;You, Chuangang;Wang, Xingang;Liu, Yong;Han, Chunmao, and the article was included in《Scientific Reports》. The author mentioned the following in the article:

Early acute kidney injury (AKI) contributes to severe morbidity and mortality in critically burned patients. Renal inflammation plays a vital role in the progression of early AKI, acting as a therapeutic target. Astaxanthin (ATX) is a strong antioxidant widely distributed in marine organisms that exerts many biol. effects in trauma and disease. ATX is also suggested to have anti-inflammatory activity. Hence, we attempted to explore the role of ATX in protecting against early postburn AKI via its anti-inflammatory effects and the related mechanisms. A severely burned model was established for histol. and biochem. assessments based on adult male rats. We found that oxidative stress-induced tissue inflammation participated in the development of early AKI after burn injury and that the MyD88-dependent TLR4/NF-κB pathway was activated to regulate renal inflammation. The TLR4 and NF-κB inhibitors TAK242 and PDTC showed similar effects in attenuating burn-induced renal inflammation and early AKI. Upon ATX treatment, the release of inflammatory mediators in the kidneys was downregulated, while the TLR4/MyD88/NF-κB axis was inhibited in a dose-related manner. TAK242 and PDTC could enhance the anti-inflammatory effect of high-dose ATX, whereas lipopolysaccharide (LPS) reversed its action. Furthermore, the expression of heme oxygenase (HO)-1 was upregulated by ATX in a dose-related manner. Collectively, the above data suggest that ATX protects against renal inflammation in a dose-related manner by regulating the TLR4/MyD88/NF-κB axis and HO-1 and ultimately prevents early AKI following severe burns. And (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) was used in the research process.

P.;Antunes, Edson published 《Lipopolysaccharide reduces urethral smooth muscle contractility via cyclooxygenase activation》 in 2021. The article was appeared in 《Journal of Physiology and Biochemistry》. They have made some progress in their research.Reference of (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate The article mentions the following:

In the present study, we evaluated the functional and mol. effects of LPS in mouse USM in vitro, focusing on the LPS-induced TLR4-signaling pathway. Male C57BL6/JUnib and TLR4 knockout mice (TLR4 KO) were used. The USM contraction was performed in the presence of LPS (62.5-500μg/mL), indomethacin (10μM), L-NAME (100μM), and TAK 242 (1μM). The RT-PCR assay for the IL-1β, NF-kB, and COX-2 genes was also evaluated in the presence of LPS (125μg/mL) and caspase 1 inhibitor (20μM). Our results showed that LPS reduces mouse USM contraction elicited by phenylephrine and vasopressin. This LPS-induced urethral inhibitory effect was not reversed by the TLR4 inhibition or its absence in the TLR4 KO mice. Conversely, indomethacin (but not L-NAME) reversed the LPS-induced USM hypocontractility. Mol. protocols indicated upregulation of IL-1β, NF-kβ, and COX-2 mRNA upon LPS incubation, which were blunted by caspase 1 inhibition. Our data showed that LPS reduced mouse USM contraction independently of TLR4 activation, involving caspase 1 and IL1β, NF-kB, and COX-2 gene overexpression. Therefore, this alternative pathway might be a valuable target to reduce the LPS-induced urethral dysfunction under infection and inflammatory conditions. To complete the study, the researchers used (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) .

Safety of (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylateIn 2022, Liu, Yanyao;Pu, Xingyu;Qin, Xiaoyan;Gong, Junhua;Huang, Zuotian;Luo, Yunhai;Mou, Tong;Zhou, Baoyong;Shen, Ai;Wu, Zhongjun published 《Neutrophil extracellular traps regulate HMGB1 translocation and kupffer cell M1 polarization during acute liver transplantation rejection》. 《Frontiers in Immunology》published the findings. The article contains the following contents:

Neutrophil extracellular traps (NETs) play important roles in hepatic ischemic reperfusion injury (IRI) and acute rejection (AR)-induced immune responses to inflammation. After liver transplantation, HMGB1, an inflammatory mediator, contributes to the development of AR. Even though studies have found that HMGB1 can promote NET formation, the correlation between NETs and HMGB1 in the development of AR following liver transplantation has not been elucidated. In this study, levels of serum NETs were significantly elevated in patients after liver transplantation. Moreover, we found that circulating levels of NETs were neg. correlated with liver function. In addition, liver transplantation and elevated extracellular HMGB1 promoted NET formation. The HMGB1/ TLR-4/MAPK signaling pathway, which is initiated by HMGB1, participates in NET processes. Moreover, in the liver, Kupffer cells were found to be the main cells secreting HMGB1. NETs induced Kupffer cell M1 polarization and decreased the intracellular translocation of HMGB1 by inhibiting DNase-1. Addnl., co-treatment with TAK-242 (a TLR-4 inhibitor) and rapamycin more effectively alleviated the damaging effects of AR following liver transplantation than either drug alone. And (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) was used in the research process.

Buravlev, E. V.;Chukicheva, I. Yu.;Shevchenko, O. G.;Kutchin, A. V. published 《Synthesis and membrane-protective activity of 2,6-diisobornylphenol derivatives with N- and O-containing fragments at position 4》 in 2017. The article was appeared in 《Russian Chemical Bulletin》. They have made some progress in their research.SDS of cas: 39637-74-6 The article mentions the following:

Two series of new amide derivatives containing 2,6-diisobornylphenol moiety were synthesized based on 3,5-diisobornyl-4-hydroxybenzoic acid and 4-butylaminomethyl-2,6-diisobornylphenol. Toxicity, membrane-protective (MP) and antioxidant (AO) activity of the obtained compounds were evaluated using red blood cells of laboratory mice as the test object. The tests demonstrated the absence of hemolytic activity for all the synthesized derivatives and the presence of high MP and AO activity under conditions of acute H₂O₂-induced oxidative stress for (3,5-diisobornyl-4-hydroxyphenyl)(morpholino)methanone and N-n-butyl-N-(3,5-diisobornyl-4-hydroxybenzyl)acetamide. A comparison of the data of the newly obtained compounds and those of described earlier 2,6-diisobornylphenol derivatives with N- and O-containing fragments at position 4 (alkoxymethyl, carboxy, and aminomethyl derivatives) led to a conclusion that the most promising for further studies of pharmacol. activity are compounds containing methoxycarbonyl, methoxymethyl, ethoxymethyl, morpholinomethyl, di-n-butylaminomethyl, (azepan-1-yl)methyl, or N-acetyl-N-alkylaminomethyl function, which provide low toxicity and high MP and AO activity.(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) were involved in the experimental procedure.

Yamasuso, Shohei;Kawai, Taketoshi published 《Electronic states and relaxation dynamics of Au centers in RbCl crystals》 in 2021. The article was appeared in 《Journal of Luminescence》. They have made some progress in their research.Reference of Rubidiumchloride The article mentions the following:

We investigated the electronic states and nonradiative transitions among the relaxed excited states of Au- centers in RbCl crystals. To this end, we measured the temperature dependences of the luminescence intensities and decay time constants of the A’, B’, and C’ luminescence bands, which are attributed to the radiative transitions from the relaxed excited states of Au- centers. The intensities and decay time constants of these luminescence bands change with temperature, through the thermally activated nonradiative transitions among the relaxed excited states. The temperature dependences of the luminescence intensities and decay time constants were analyzed utilizing rate equations, except the decay time constant of the C’ luminescence. From the best fitting results, the activation energies of the relaxed excited states are estimated The C’ luminescence has a longer decay time constant than that expected from the dipole-allowed transition. The temperature dependence of the decay time of the C’ luminescence is discussed by considering a trapped level. The experimental procedure involved many compounds, such as Rubidiumchloride (cas: 7791-11-9) .

Reynolds, Kathryn E.;Krasovska, Victoria;Scott, Angela L. published 《Converging purinergic and immune signaling pathways drive IL-6 secretion by Fragile X cortical astrocytes via STAT3》 in 2021. The article was appeared in 《Journal of Neuroimmunology》. They have made some progress in their research.Application In Synthesis of (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate The article mentions the following:

Fragile X syndrome (FXS), the most common heritable form of autism spectrum disorder (ASD), is characterized by an absence of the FMRP protein resulting from expanded and hypermethylated CGG repeats within the Fmr1 gene. FXS are driven in part by abnormal glial-mediated function. FXS astrocytes release elevated levels of immune-related factors interleukin-6 (IL-6) and tenascin C (TNC), and also demonstrate increased purinergic signaling, a pathway linked to signaling factor release. Here, in cortical astrocytes from the Fmr1 knockout (KO) FXS mouse model, purinergic agonism enhanced TNC secretion and STAT3 phosphorylation, two processes linked to elevated IL-6 secretion in FXS, while STAT3 knockdown and TLR4 antagonism normalized Fmr1 KO IL-6 release. Author therefore suggest that purinergic signaling and immune regulatory pathways converge to drive FXS cortical pro-inflammatory responses.(R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) were involved in the experimental procedure.

The article contains the following contents:

At present, most rheumatoid arthritis (RA) patients are at risk of osteoporosis (OP), which is increased by 1.5 times compared to non-RA individuals. Hence, we investigated overlapping targets related directly to the occurrence and development of RA and OP through public databases (DisGeNET, and OMIM) and literature. A total of 678 overlapping targets were considered as comorbid factors, and 604 out of 678 were correlated with one another. Interleukin 6 (IL-6), with the highest degree of value in terms of protein-protein interaction (PPI), was considered to be a core target against comorbidity. We identified 31 existing small mols. (< 1000 g/mol) as IL-6 inhibitors, and 19 ligands were selected by the 3 primary criteria (Lipinski′s rule, TPSA, and binding energy). We postulated that MD2-TLR4-IN-1 (PubChem ID: 138454798), as confirmed by the three criteria, was the key ligand to alleviate comorbidity between RA and OP. In conclusion, we described a promising active ligand (MD2-TLR4-IN-1), and a potential target (IL-6) against comorbidity of RA and OP, providing scientific evidence for a further clin. trial. And (R)-Ethyl 6-(N-(2-chloro-4-fluorophenyl)sulfamoyl)cyclohex-1-enecarboxylate (cas: 243984-11-4) was used in the research process.

Reference of Rubidiumchloride《Structuring of reference data on the hygroscopic points of soluble substances》 was published in 2021. The authors were Tereshchenko, Anatoly G., and the article was included in《Journal of Chemical Thermodynamics》. The author mentioned the following in the article:

The article considers a way to expand the capabilities of the dynamic method for measuring hygroscopic points (equilibrium water vapor pressure over saturated solutions of substances) of solubles by applying it to an ordered series of substances with their hygroscopic points in a narrow range of (68-76)% RH. The exptl. measured values of hygroscopic points are proposed as reference data on the hygroscopicity of such substances as carbamide, rubidium chloride, sodium nitrate, strontium chloride; the values for barium bromide and lithium perchlorate are clarified. The capability of the dynamic method to measure the difference between the hygroscopic points of substances enhances its consistency and reliability, makes it possible to present reference data in a structured form. Along with the simplicity of the procedure and the laboratory equipment used, this makes the proposed version of the dynamic method highly competitive among the other methods for determining water vapor pressure over saturated solutions of substances. The experimental procedure involved many compounds, such as Rubidiumchloride (cas: 7791-11-9) .
