42926-91-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42926-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42926-91:
(7*4)+(6*2)+(5*9)+(4*2)+(3*6)+(2*9)+(1*1)=130
130 % 10 = 0
So 42926-91-0 is a valid CAS Registry Number.

Synthesis of Fondaparinux: Modular synthesis investigation for heparin synthesis

Lin, Feng,Lian, Gaoyan,Zhou, Ying

, p. 32 - 39 (2013/05/09)

The anti-thromboembolic pentasaccharide Fondaparinux was synthesized in 36 steps for the longest linear route, with 0.017% overall yield from d-glucose. Only three kinds of protecting groups were used for hydroxyl protection, Bn, Ac, and Bz, to accomplish this complex synthesis without decreasing the synthetic efficiency. Three l-idopyranosyl donors were investigated. Thioethyl glycoside is an efficient donor for l-idopyranosyl glycosylation with full α-selectivity, while l-idopyranosyl trichloroacetimidate resulted in poor α/β selectivity. A practical synthesis of key intermediate 1,6-anhydro-l-idopyranose 17 by H+/β-CD catalyst was developed.

Synthesis of heparin oligosaccharides and their interaction with eosinophil-derived neurotoxin

Hung, Shang-Cheng,Lu, Xin-An,Lee, Jinq-Chyi,Chang, Margaret Dah-Tsyr,Fang, Shun-Lung,Fan, Tan-Chi,Zulueta, Medel Manuel L.,Zhong, Yong-Qing

, p. 760 - 772 (2012/02/05)

A convenient route for the synthesis of heparin oligosaccharides involving regioselective protection of d-glucosamine and a concise preparation of rare l-ido sugars from diacetone α-d-glucose is described. Stereoselective coupling of a d-glucosamine-derived trichloroacetimidate with a 1,6-anhydro-β-l-idopyranosyl 4-alcohol gave the desired α-linked disaccharide, which was used as repeating unit for dual chain elongation and termination. Stepwise assembly from the reducing to the non-reducing end with a d-glucosamine-derived monosaccharide as starting unit furnished the oligosaccharide skeletons having different chain lengths. A series of functional group transformations afforded the expected heparin oligosaccharides with 3, 5 and 7 sugar units. Interaction of these oligosaccharides with eosinophil-derived neurotoxin (EDN), a cationic ribonuclease and a mediator produced by human eosinophils, was further investigated. The results revealed that at 5 μg mL-1, the heptasaccharide has sufficiently strong interference to block EDN binding to Beas-2B cells. The tri- and pentasaccharides have moderate inhibitory properties at 50 μg mL-1 concentration, but no inhibition has been observed at 10 μg mL-1. The IC50 values of the tri-, penta- and heptasaccharides are 69.4, 47.2 and 0.225 μg mL-1, respectively.

From D-Glucose to Biologically Potent L-Hexose Derivatives: Synthesis of α-L-Iduronidase Fluorogenic Detector and the Disaccharide Moieties of Bleomycin A2 and Heparan Sulfate

Lee, Jinq-Chyi,Chang, Shu-Wen,Liao, Chih-Cheng,Chi, Fa-Chen,Chen, Chien-Sheng,Wen, Yuh-Sheng,Wang, Cheng-Chung,Kulkarni, Suvarn S.,Puranik, Ramachandra,Liu, Yi-Hung,Hung, Shang-Cheng

, p. 399 - 415 (2007/10/03)

A novel and convenient route for the synthesis of biologically potent and rare L-hexose derivatives from D-glucose is described. Conversion of diacetone-α-D-glucose (14) into 1,2:3,5-di-O-isopropylidene-β -L-idofuranose (19) was efficiently carried out in two steps. Orthogonal isopropylidene rearrangement of compound 19 led to 1,2:5,6-di-O-isopropylidene-β-L-idofuranose (27), which underwent regioselective epimerization at the C3 position to give the L-talo- and 3-functionalized L-idofuranosyl derivatives. Hydrolysis of compound 19 under acidic conditions furnished 1,6-anhydro-β-L-idopyranose (35) in excellent yield, which was successfully transformed into the corresponding L-allo, L-altro, L-gulo, and L-ido derivatives via regioselective benzylation, benzoylation, triflation and nucleophilic substitution as the key steps. Applications of these 1,6-anhydro-β-L-hexopyranoses as valuable building blocks to the syntheses of 4-methylcoumarin-7-yl-α-L-iduronic acid and the disaccharide moieties of bleomycin A2 as well as heparan sulfate are highlighted.
