Check Digit Verification of cas no

The CAS Registry Mumber 42891-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42891-22:
(7*4)+(6*2)+(5*8)+(4*9)+(3*1)+(2*2)+(1*2)=125
125 % 10 = 5
So 42891-22-5 is a valid CAS Registry Number.

Symmetric dithiodigalactoside: Strategic combination of binding studies and detection of selectivity between a plant toxin and human lectins

Martin-Santamaria, Sonsoles,Andre, Sabine,Buzamet, Eliza,Caraballo, Remi,Fernandez-Cureses, Gloria,Morando, Maria,Ribeiro, Joao P.,Ramirez-Gualito, Karla,De Pascual-Teresa, Beatriz,Canada, F. Javier,Menendez, Margarita,Ramstroem, Olof,Jimenez-Barbero, Jesus,Solis, Dolores,Gabius, Hans-Joachim

, p. 5445 - 5455 (2011)

Thioglycosides offer the advantage over O-glycosides to be resistant to hydrolysis. Based on initial evidence of this recognition ability for glycosyldisulfides by screening dynamic combinatorial libraries, we have now systematically studied dithiodigalactoside on a plant toxin (Viscum album agglutinin) and five human lectins (adhesion/growth-regulatory galectins with medical relevance e.g. in tumor progression and spread). Inhibition assays with surface-presented neoglycoprotein and in solution monitored by saturation transfer difference NMR spectroscopy, flanked by epitope mapping, as well as isothermal titration calorimetry revealed binding properties to VAA (K a: 1560 ± 20 M-1). They were reflected by the structural model and the affinity on the level of toxin-exposed cells. In comparison, galectins were considerably less reactive, with intrafamily grading down to very minor reactivity for tandem-repeat-type galectins, as quantitated by radioassays for both domains of galectin-4. Model building indicated contact formation to be restricted to only one galactose moiety, in contrast to thiodigalactoside. The tested glycosyldisulfide exhibits selectivity between the plant toxin and the tested human lectins, and also between these proteins. Therefore, glycosyldisulfides have potential as chemical platform for inhibitor design.

Synthesis and Structure-Activity Relationship Study of Antimicrobial Auranofin against ESKAPE Pathogens

Wu, Bin,Yang, Xiaojian,Yan, Mingdi

, p. 7751 - 7768 (2019/09/10)

Auranofin, an FDA-approved arthritis drug, has recently been repurposed as a potential antimicrobial agent; it performed well against many Gram-positive bacteria, including multidrug resistant strains. It is, however, inactive toward Gram-negative bacteria, for which we are in dire need of new therapies. In this work, 40 auranofin analogues were synthesized by varying the structures of the thiol and phosphine ligands, and their activities were tested against ESKAPE pathogens. The study identified compounds that exhibited bacterial inhibition (MIC) and killing (MBC) activities up to 65 folds higher than that of auranofin, making them effective against Gram-negative pathogens. Both thiol and the phosphine structures influence the activities of the analogues. The trimethylphosphine and triethylphosphine ligands gave the highest activities against Gram-negative and Gram-positive bacteria, respectively. Our SAR study revealed that the thiol ligand is also very important, the structure of which can modulate the activities of the AuI complexes for both Gram-negative and Gram-positive bacteria. Moreover, these analogues had mammalian cell toxicities either similar to or lower than that of auranofin.

SYNTHESIS AND USE OF GLYCODENDRIMER REAGENTS

-

Page/Page column 44; 54; sheet 19, (2010/11/08)

The present invention relates to a chemically modified mutant protein including a cysteine residue substituted for a residue other than cysteine n a precursor protein, the substituted cysteine residue being subsequently modified by reacting the cysteine residue with a glycosylated thiosulfonate. Also a method of producing the chemically modified mutant protein is provided. The present invention also relates to a glycosylated methanethiosulfonate. Another aspect of the present invention is a method of modifying the functional characteristics of a protein including providing a protein and reacting the protein with a glycosylated methanethiosulfonate reagent under conditions effective to produce a glycoprotein with altered functional characteristics as compared to the protein. In addition, the present invention relates to methods of determining the structure-function relationships of chemically modified mutant proteins. The present invention also relates to synthetic methods for producing thio-glycoses, the thio-glycoses so produced, and to methods for producing glycodendrimer reagents.

Glycosylimidates, 8. - Synthesis of 1-Thioglycosides

Schmidt, Richard R.,Stumpp, Michael

, p. 1249 - 1256 (2007/10/02)

As expected, the reactive acetyl-protected O-(α-D-glucopyranosyl) trichloroacetimidate 3 reacts with S-nucleophiles and trifluoroborane-ether as catalyst to yield exclusively 1-thio-β-D-glucopyranosides with inversion of the configuration.The corresponding benzyl-protected α-trichloroacetimidate 4 affords with retention of the configuration alkyl 1-thio-α-D-glucopyranosides.The importance of alkyl 1-thio-β-D-galactopyranosides in enzyme induction was reason to apply this convenient and efficient glycosyl-transfer reaction to the synthesis of isopropyl 1-thio-β-D-galactopyranoside (12a) and the sodium salt of 1-thio-β-D-galactopyranose (12b), respectively.
