Formula: C13H17BrO9In 2022 ,《A novel synthesis of tetrahydrocortisone 3-glucuronide》 was published in Journal of Carbohydrate Chemistry. The article was written by Zhang, Yan; Zhang, Suqing; Li, Rui; Shen, Jingshan; Jiang, Xiangrui; Aisa, Haji A.. The article contains the following contents:

A new route for the synthesis of tetrahydrocortisone 3-glucuronide has been developed with cortisone acetate as a starting material. The key step was using lithium tri-tert-butoxyaluminum hydride to reduce the C-3 carbonyl group of 5β-dihydrocortisone acetate to provide 3α-5β-tetrahydrocortisone acetate. Then, Koenig-Knorr method was used for glycosylation with glycosyl bromide as the donor, cadmium carbonate as promoter and 4Å mol. sieves as dehydrating agent to give high yield of the desired product. The new route is shorter and gives higher yield than that reported in the literature. In the part of experimental materials, we found many familiar compounds, such as (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Formula: C13H17BrO9)

Detection and isolation of both O157:H7 and non-O157:H7 Escherichia coli are essential for the evaluation and surveillance of the associated foodborne disease risk. However, the development of a chromogenic/fluorogenic culture medium for detection and isolation is challenging yet urgent. β-Glucuronidase (GUS) serves as an important biomarker in E. coli. A novel and simple off-on fluorogenic substrate (BTBP-Gluc) was developed, based on a solid-state fluorophore (BTBP) with excited-state intramol. proton transfer (ESIPT) and aggregation-induced emission (AIE) effects. BTBP-Gluc could be well-suited for visually detecting GUS activity under acidic conditions. It was successfully applied for detection of endogenous intracellular GUS activity in living E. coli and could produce the in situ and long-term localization of the target colonies and cell imaging of living E. coli. Addnl., it showed high selectivity, little toxicity, excellent cell permeability and sensitivity. BTBP-Gluc was combined with two tightly localizing chromogenic substrates, Magenta-Gal and X-Glu. These combinations were applied to the development of a new chromogenic-fluorogenic culture medium. On this new agar simultaneous visual detection and isolation of O157:H7 and non-O157:H7 E. coli with relatively high accuracy was achieved. C-F E. coli agar shows potential in serving as a simple sensitive tool for detecting and isolating O157:H7 and non-O157:H7 E. coli in food samples such as milk. In the experiment, the researchers used (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Quality Control of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate)

Wei, Xianzhe; Hao, Mengjiao; Hu, Xiao-Xiao; Song, Zhiling; Wang, Yan; Sun, Ronghuan; Zhang, Jing; Yan, Mei; Ding, Biyan; Yu, Jinghua published an article in 2021. The article was titled 《A near-infrared fluorescent probe with large stokes shift for accurate detection of β-glucuronidase in living cells and mouse models》, and you may find the article in Sensors and Actuators, B: Chemical.Quality Control of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate The information in the text is summarized as follows:

β-Glucuronidase (GLU) plays a vital role in the growth, migration, angiogenesis, and metastasis of tumors. The reliable detection of GLU is an effective approach for early diagnosis of numerous disease such as cholelithiasis and colorectal cancer. In this work, a near-IR fluorescent probe (DP-GLU) with a large Stokes shift was rationally designed for accurate detection of GLU in living cells and mouse models. DP-GLU was composed of two moieties: dicyanoisophorone as NIR fluorophore and enzyme substrate as GLU recognizable group. Upon reaction with GLU, DP-GLU rapidly displayed a strong emission at 676 nm and the Stokes shift could reach 131 nm. DP-GLU also exhibited high sensitivity toward GLU, and the linearity was fitted in the concentration range of 0-100 μg/L with the detection limit as low as 1.45 x 10-2 μg/L. Furthermore, DP-GLU was used for distinguishing GLU-overexpression tumor cells from normal cells and revealed functions of noninvasive tracking GLU levels in mouse tumor models. Remarkably, DP-GLU was great potential application for cancer imaging in the early diagnoses and therapies of pathologies, which could obtain a comprehensive of the physiol. functions of GLU. The experimental process involved the reaction of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Quality Control of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate)

Anselmi, Michele; Borbely, Adina; Figueras, Eduard; Michalek, Carmela; Kemker, Isabell; Gentilucci, Luca; Sewald, Norbert published an article in 2021. The article was titled 《Linker hydrophilicity modulates the anticancer activity of RGD-cryptophycin conjugates》, and you may find the article in Chemistry – A European Journal.SDS of cas: 21085-72-3 The information in the text is summarized as follows:

Most anticancer agents are hydrophobic and can easily penetrate the tumor cell membrane by passive diffusion. This may impede the development of highly effective and tumor-selective treatment options. A hydrophilic β-glucuronidase-cleavable linker was used to connect the highly potent antimitotic agent cryptophycin-55 glycinate with the αvβ3 integrin ligand c(RGDfK). Incorporation of the self-immolative linker containing glucuronic acid results in lower cytotoxicity than that of the free payload, suggesting that hydrophilic sugar linkers can preclude passive cellular uptake. In vitro drug-release studies and cytotoxicity assays demonstrated the potential of this small mol.-drug conjugate, providing guidance for the development of therapeutics containing hydrophobic anticancer drugs. The experimental part of the paper was very detailed, including the reaction process of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3SDS of cas: 21085-72-3)

Category: bromides-buliding-blocksIn 2021 ,《Synthesis and anti-inflammatory activity of saponin derivatives of δ-oleanolic acid》 was published in European Journal of Medicinal Chemistry. The article was written by Liu, Liu; Li, Haobin; Hu, Kaiwen; Xu, Qinglong; Wen, Xiaoan; Cheng, Keguang; Chen, Caiping; Yuan, Haoliang; Dai, Liang; Sun, Hongbin. The article contains the following contents:

Pentacyclic triterpenes (PTs) are the active ingredients of many medicinal herbs and pharmaceutical formulations, and are well-known for their anti-inflammatory activity. Recently, the anti-inflammatory effects of AMP-activated protein kinase (AMPK) have also drawn much attention. In this study, the authors found that a variety of naturally occurring PTs sapogenins and saponins could stimulate the phosphorylation of AMPK, and identified δ-oleanolic acid as a potent AMPK activator. Based on these findings, 23 saponin derivatives of δ-oleanolic acid were synthesized in order to find more potent anti-inflammatory agents with improved pharmacokinetic properties. The results of cellular assays showed that saponin I significantly inhibited LPS-induced secretion of pro-inflammatory factors TNF-α and IL-6 in THP1-derived macrophages. Preliminary mechanistic studies showed that I stimulated the phosphorylation of AMPK and acetyl-CoA carboxylase (ACC). The bioavailability of I was significantly improved in comparison with its aglycon. More importantly, I showed significant anti-inflammatory and liver-protective effects in LPS/D-GalN-induced fulminant hepatic failure mice. Taken together, PTs saponins hold promise as therapeutic agents for inflammatory diseases. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Category: bromides-buliding-blocks)

Recommanded Product: 21085-72-3 And the article was included in Journal of Medicinal Chemistry in 2020. The article conveys some information:

Pregnane X receptor (PXR) is a master xenobiotic-sensing transcription factor and a validated target for immune and inflammatory diseases. The identification of chem. probes to investigate the therapeutic relevance of the receptor is still highly desired. In fact, currently available PXR ligands are not highly selective and can exhibit toxicity and/or potential off-target effects. In this study, we have identified garcinoic acid as a selective and efficient PXR agonist. The properties of this natural mol. as a specific PXR agonist were demonstrated by the screening on a panel of nuclear receptors, the assessment of the phys. and thermodn. binding affinity, and the determination of the PXR-garcinoic acid complex crystal structure. Cytotoxicity, transcriptional, and functional properties were investigated in human liver cells, and compound activity and target engagement were confirmed in vivo in mouse liver and gut tissue. In conclusion, garcinoic acid is a selective natural agonist of PXR and a promising lead compound toward the development of new PXR-regulating modulators. The experimental part of the paper was very detailed, including the reaction process of (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Recommanded Product: 21085-72-3)

The article was titled 《Excited-State Palladium-Catalyzed Radical Migratory Mizoroki-Heck Reaction Enables C2-Alkenylation of Carbohydrates》, and you may find the article in Journal of the American Chemical Society.Category: bromides-buliding-blocks The information in the text is summarized as follows:

Excited-state palladium catalysis has emerged as a promising strategy for developing novel and valuable reactions. Herein, we report the first excited-state Pd-catalyzed 1,2-radical migratory Mizoroki-Heck reaction that enables C2-alkenylation of carbohydrates using readily available 1-bromosugars and alkenes. The reaction tolerates a wide variety of functional groups and complex mol. architectures, including derivatives of natural products and marketed drugs. Preliminary mechanistic studies and DFT calculations suggest the involvement of visible-light-induced photoexcitation of Pd species, 1,2-spin-centered-shift (SCS) process, and Heck-type cross-coupling reaction. The reaction expands the reactivity profile of excited-state Pd catalysis and provides a streamlined protocol for the preparation of a wide variety of C2-alkenylated carbohydrate mimetics to aid the discovery and development of new therapeutics, agrochems., and materials. In addition to this study using (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate, there are many other studies that have used (2R,3R,4S,5S,6S)-2-Bromo-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate(cas: 21085-72-3Category: bromides-buliding-blocks) was used in this study.
