21085-72-3 Usage

Uses

Used in Pharmaceutical Industry:
ACETOBROMO-ALPHA-D-GLUCURONIC ACID METHYL ESTER is used as a synthetic intermediate for the development of HMR1098-S-glucuronide methyl ester, a novel K-ATP-blocking agent. ACETOBROMO-ALPHA-D-GLUCURONIC ACID METHYL ESTER is being researched for its potential in preventing sudden cardiac death.
Used in Cancer Treatment:
ACETOBROMO-ALPHA-D-GLUCURONIC ACID METHYL ESTER is utilized in the synthesis of water-soluble glucuronide derivatives of Camptothecin. These derivatives are employed in cancer prodrug monotherapy and antibody-directed enzyme prodrug therapy (ADEPT), enhancing the targeted delivery and efficacy of Camptothecin in cancer treatment.
Used in Inflammatory Disease Treatment:
ACETOBROMO-ALPHA-D-GLUCURONIC ACID METHYL ESTER is also used in the synthesis of glucuronide prodrug compounds of the Janus kinase (JAK) inhibitor tofacitinib. These prodrugs can be cleaved by β-glucuronidase enzymes, such as those produced by the microbiome in the gastrointestinal tract. This targeted release increases the levels of tofacitinib at the site of gastrointestinal inflammation while limiting systemic exposure, making it a more effective treatment for localized inflammatory diseases.

Check Digit Verification of cas no

The CAS Registry Mumber 21085-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,8 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21085-72:
(7*2)+(6*1)+(5*0)+(4*8)+(3*5)+(2*7)+(1*2)=83
83 % 10 = 3
So 21085-72-3 is a valid CAS Registry Number.

Synthesis and positive inotropic activity evaluation of liguzinediol metabolites

Zhu, Hao-Hao,Chen, Yu-Qing,Cheng, Dong,Li, Wei,Wang, Tian-Lin,Wen, Hong-Mei,Chen, Long,Liu, Jian

, p. 882 - 884 (2016)

2,5-Dihydroxymethyl-3,6-dimethylpyrazine (liguzinediol) has been recently discovered as a potential agent for treatment of heart failure with low safety risk. In the present study, four main metabolites of liguzinediol were synthesized and their positive inotropic activities were evaluated. Synthetic compounds were identical with the isolated metabolites of liguzinediol. Pharmacological examinations showed that the four major metabolites were not observed positive inotropic activity, and revealed that the positive inotropic activity of liguzinediol was essentially attributed to the parent agent.

Synthesis and Antimicrobial Activity of Glucuronosyl Derivatives of Steviolbioside from Stevia rebaudiana

Sharipova,Andreeva,Strobykina, I. Yu.,Voloshina,Strobykina,Kataev

, p. 1107 - 1111 (2017)

Glucuronosyl derivatives of the glycoside steviolbioside from Stevia rebaudiana were synthesized for the first time. Steviolbioside exhibited selective bacteriostatic and bactericidal activity against S. aureus ATCC 209p with minimum inhibitory concentration (MIC) of 62.5 μg/mL, which corresponded to the activity of the antibiotic chloramphenicol.

Solid state structure of sodium β-1-thiophenyl glucuronate identifies 5-coordinate sodium with three independent glucoronates

Alharthi, Fahad Ayesh,Whitehead, George F.S.,Vitórica-Yrezábal, I?igo J.,Gardiner, John M.

, (2021)

Glucuronic acid is a key component of the glycosaminoglycans (GAGs) Chrondroitin Sulfate (CS), Heparin/Heparan sulfate (HS) and Hyaluronic Acid (HA), as well an important metabolite derivative. In biological systems the carboxylate of uronic acids in GAGs is involved in important H-binding interactions, and the role of metal coordination, such as sodiated systems, has indications associated with a number of biological effects, and physiological GAG-related processes. In synthetic approaches to GAG fragments, thioglycoside intermediates, or derivatives from these, are commonly employed. Of the reported examples of sodium coordination in carbohydrates, 6-coordinate systems are usually observed often with water ligands involved, Herein we report an unexpected 5-coordinate sodiated GlcA crystal structure of the parent GlcA, but as a thioglycoside derivative, whose crystal coordination differs from previous examples, with no involvement of water as a ligand and containing a distorted trigonal bypramidal sodium with each GlcA having five of 6 oxygens sodium-coordinated.

Development of synthetic approaches to macrocyclic glycoterpenoids on the basis of glucuronic acid and diterpenoid isosteviol

Andreeva,Sharipova,Strobykina, I. Yu.,Kravchenko,Strobykina,Voloshina,Musin,Kataeva

, p. 1324 - 1333 (2015)

An approach has been developed to the synthesis of macrocyclic glycoterpenoids containing diterpenoid isosteviol and glucuronic acid fragments. Selective screening revealed compounds exhibiting antitubercular activity against H37RV, M. Avium, and M. Terrae strains at a level comparable to the known antitubercular drugs isoniazid, ofloxacin, and pyrazinamide. The compound possessing the highest antitubercular activity is non-cytotoxic toward human erythrocytes.

Liu, Chun-He,Liu, He,Han, Xiang-Yu,Wu, Bo,Zhong, Bo-Hua,Gong, Ze-Hui

, p. 701 - 710 (2005)

Thienorphine (1) is a very potent oripavine derivative with mixed agonist and antagonist opioid receptor activities. It was prepared with 7α-acetyl-6,14-endoethenotetrahydrothebaine as stated material by Grignard reaction, cyanidation, demethylation, and N-alkylation. The structure of 1 · HCl was elucidated by X-ray analysis. As part of a continuing program to define the metabolism and distribution of thienorphine in animals and man, the putative metabolite, 3-glucuronide, was synthesized.

COMPOUNDS, COMPOSITIONS, METHODS, AND USES FOR TREATING CANCER AND IMMUNOLOGICAL DISORDERS

-

Paragraph 0546; 0568, (2020/02/06)

The present disclosure provides novel polypeptide-therapeutic compound or hormone-therapeutic compound conjugates using cleavable or non-cleavable linkers, whereby the polypeptide or hormone serves to target specific cells using receptor expression on the targeted cell to bind the ligand (polypeptide or hormone) carrying the therapeutic compound unlike antibody drug conjugates. Upon binding, the ligand and the therapeutic compound (multiples of the therapeutic compound in some embodiments) enter the cell by receptor-mediated endocytosis, and release drugs conjugated to the ligand by linkers, to interact with intracellular components to enhance, restore, or block a signal transduction process. The ligands for the polypeptide-therapeutic compound or hormone-therapeutic compound conjugates include, but are not limited to: cytokines, growth factors and hormones among other proteins with corresponding cell surface specific receptors. The disorders targeted by such polypeptide-therapeutic compound or hormone-therapeutic compound conjugates include, but are not limited to: immunological disorders (e.g., allergy and autoimmune disorders) and cancer.
