Check Digit Verification of cas no

The CAS Registry Mumber 31873-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,7 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31873-41:
(7*3)+(6*1)+(5*8)+(4*7)+(3*3)+(2*4)+(1*1)=113
113 % 10 = 3
So 31873-41-3 is a valid CAS Registry Number.

Glycosyl phenylthiosulfonates (glyco-PTS): novel reagents for glycoprotein synthesis.

Gamblin, David P,Garnier, Philippe,Ward, Sarah J,Oldham, Neil J,Fairbanks, Antony J,Davis, Benjamin G

, p. 3642 - 3644 (2003)

Controlled site-selective glycosylation can be achieved by combining site-directed cysteine mutagenesis with chemical modification of the introduced thiol; a new class of more efficient chemoselective reagents, glycosyl phenylthiosulfonates, allow rapid glycosylations of representative simple thiols, peptides and proteins.

Design, synthesis of oleanolic acid-saccharide conjugates using click chemistry methodology and study of their anti-influenza activity

Su, Yangqing,Meng, Lingkuan,Sun, Jiaqi,Li, Weijia,Shao, Liang,Chen, Kexuan,Zhou, Demin,Yang, Fan,Yu, Fei

, (2019/08/20)

The development of entry inhibitors is an emerging approach to the inhibition of influenza virus. In our previous research, oleanolic acid (OA) was discovered as a mild influenza hemagglutinin (HA) inhibitor. Herein, as a further study, we report the preparation of a series of OA-saccharide conjugates via the CuAAC reaction, and the anti-influenza activity of these compounds was evaluated in vitro. Among them, compound 11b, an OA-glucose conjugate, showed a significantly increased anti-influenza activity with an IC50 of 5.47 μM, and no obvious cytotoxic effect on MDCK cells was observed at 100 μM. Hemagglutination inhibition assay and docking experiment indicated that 11b might interfere with influenza virus infection by acting on HA protein. Broad-spectrum anti-influenza experiments showed 11b to be robustly potent against 5 different strains, including influenza A and B viruses, with IC50 values at the low-micromole level. Overall, this finding further extends the utility of OA-saccharide conjugates in anti-influenza virus drug design.

Saccharide-functionalized alkanethiols for fouling-resistant self-assembled monolayers: Synthesis, monolayer properties, and antifouling behavior

Fyrner, Timmy,Lee, Hung-Hsun,Mangone, Alberto,Ekblad, Tobias,Pettitt, Michala E.,Callow, Maureen E.,Callow, James A.,Conlan, Sheelagh L.,Mutton, Robert,Clare, Anthony S.,Konradsson, Peter,Liedberg, Bo,Ederth, Thomas

experimental part, p. 15034 - 15047 (2012/04/10)

We describe the synthesis of a series of mono-, di-, and trisaccharide-functionalized alkanethiols as well as the formation of fouling-resistant self-assembled monolayers (SAMs) from these. The SAMs were characterized using ellipsometry, wetting measurements, and infrared reflection-absorption spectroscopy (IRAS). We show that the structure of the carbohydrate moiety affects the packing density and that this also alters the alkane chain organization. Upon increasing the size of the sugar moieties (from mono- to di- and trisaccharides), the structural qualities of the monolayers deteriorated with increasing disorder, and for the trisaccharide, slow reorganization dynamics in response to changes in the environmental polarity were observed. The antifouling properties of these SAMs were investigated through protein adsorption experiments from buffer solutions as well as settlement (attachment) tests using two common marine fouling species, zoospores of the green macroalga Ulva linza and cypris larvae of the barnacle Balanus amphitrite. The SAMs showed overall good resistance to fouling by both the proteins and the tested marine organisms. To improve the packing density of the SAMs with bulky headgroups, we employed mixed SAMs where the saccharide-thiols are diluted with a filler molecule having a small 2-hydroxyethyl headgroup. This method also provides a means by which the steric availability of sugar moieties can be varied, which is of interest for specific interaction studies with surface-bound sugars. The results of the surface dilution study and the low nonspecific adsorption onto the SAMs both indicate the feasibility of this approach.

Photocleavable molecule for laser desorption ionization mass spectrometry

Maki, Toshihide,Ishida, Koji

, p. 6427 - 6433 (2008/02/10)

(Figure Presented) A new photocleavable molecule for laser desorption ionization mass spectrometry (LDI-MS) was designed and synthesized. The molecule exhibited high sensitivity for negative mode MS detection with good chemical stability. The molecule was successfully applied to molecular tag for (LDI-MS). Kinetic measurement of the amidation reaction and monitoring of aminolysis of acetylated sugars were demonstrated with the molecular tag.

Saccharide-coated M12L24 molecular spheres that form aggregates by multi-interaction with proteins

Kamiya, Nozomi,Tominaga, Masahide,Sato, Sota,Fujita, Makoto

, p. 3816 - 3817 (2008/02/03)

The self-assembly of saccharide-coated nanometer-sized molecular spheres is reported, where 24 (oligo)saccharides are precisely arrayed at the periphery of the spherical core. When combined with lectins, they form aggregates because of the cluster effect of the saccharides on the spheres. Copyright

Synthesis of α-tocopheryl oligosaccharides

Lahmann, Martina,Thiem, Joachim

, p. 23 - 31 (2007/10/03)

As effective natural antioxidants, tocopherols and also their esters are frequently added to foodstuffs, pharmaceuticals and cosmetics. For increase of polarity, hence solubility in water, a series of α-tocopheryl oligosaccharides was synthesised using BF3-etherate. The pure α-tocopheryl β-maltotetraoside as well as the higher homologues proved to be water-soluble.

Glycogen-storage-disease-relating linear tetra-, hexa-, and octasaccharides of D-glucose having α(1->4) and α(1->6) linkages were synthesized using a stereoselective dehydrative glycosylation with a reagent mixture of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, N,N-dimethylacetamide, and triethylamine.A cross-condensation of a quasi-stoichiometric amount of a donor and an acceptor of an octasaccheride, followed by deprotection, afforded a glucohexadecasaccharide.
