Check Digit Verification of cas no

The CAS Registry Mumber 132748-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,4 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132748-02:
(8*1)+(7*3)+(6*2)+(5*7)+(4*4)+(3*8)+(2*0)+(1*2)=118
118 % 10 = 8
So 132748-02-8 is a valid CAS Registry Number.

Synthesis of nature product kinsenoside analogues with anti-inflammatory activity

Song, Wei,Sun, Yong,Xu, Lintao,Sun, Yajing,Li, Tianlu,Peng, Peng,Lou, Hongxiang

supporting information, (2020/12/02)

Kinsenoside is the major bioactive component from herbal medicine with a broad range of pharmacological functions. Goodyeroside A, an epimer of kinsenoside, remains less explored. In this report we chemically synthesized kinsenoside, goodyeroside A and their analogues with glycan variation, chirality inversion at chiral center(s), and bioisosteric replacement of lactone with lactam. Among these compounds, goodyeroside A and its mannosyl counterpart demonstrated superior anti-inflammatory efficacy. Furthermore, goodyeroside A was found to suppresses inflammatory through inhibiting NF-κB signal pathway, effectively. Structure-activity relationship is also explored for further development of more promising kinsenoside analogues as drug candidates.

An Empirical Understanding of the Glycosylation Reaction

Chatterjee, Sourav,Moon, Sooyeon,Hentschel, Felix,Gilmore, Kerry,Seeberger, Peter H.

supporting information, p. 11942 - 11953 (2018/09/27)

Reliable glycosylation reactions that allow for the stereo- and regioselective installation of glycosidic linkages are paramount to the chemical synthesis of glycan chains. The stereoselectivity of glycosylations is exceedingly difficult to control due to the reaction's high degree of sensitivity and its shifting, simultaneous mechanistic pathways that are controlled by variables of unknown degree of influence, dominance, or interdependency. An automated platform was devised to quickly, reproducibly, and systematically screen glycosylations and thereby address this fundamental problem. Thirteen variables were investigated in as isolated a manner as possible, to identify and quantify inherent preferences of electrophilic glycosylating agents (glycosyl donors) and nucleophiles (glycosyl acceptors). Ways to enhance, suppress, or even override these preferences using judicious environmental conditions were discovered. Glycosylations involving two specific partners can be tuned to produce either 11:1 selectivity of one stereoisomer or 9:1 of the other by merely changing the reaction conditions.

Efficient α-mannosylation of phenols: The role of carbamates as scavengers for activated glycosyl donors

Schüler, Peter,Fischer, Sebastiann.,Marsch, Michael,Oberthür, Markus

, p. 27 - 39 (2013/03/13)

The boron trifluoride activation of trichloroacetimidate donors was found to be an efficient method for the α-mannosylation of tyrosine-containing acceptors. Most notably, these conditions are compatible with the commonly used carbamate protecting groups, whereas trichloroacetimidate activation with trimethylsilyl triflate or the use of glycosyl sulfoxides led to diminished yields in the presence of carbamates. In these cases, the competing reaction of the activated donors with the carbamate group was identified as a problematic side reaction. Taking advantage of this reactivity, various glycosyl carbamates were generated for the first time under non-acidic glycosylation conditions by reaction of different Boc-protected amino acids and dipeptides with glycosyl sulfoxides under triflic anhydride activation.

Fluorine-directed β-galactosylation: Chemical glycosylation development by molecular editing

Durantie, Estelle,Bucher, Christoph,Gilmour, Ryan

supporting information; experimental part, p. 8208 - 8215 (2012/08/27)

Validation of the 2-fluoro substituent as an inert steering group to control chemical glycosylation is presented. A molecular editing study has revealed that the exceptional levels of diastereocontrol in glycosylation processes by using 2-fluoro-3,4,6-tri-O-benzyl glucopyranosyl trichloroacetimidate (TCA) scaffolds are a consequence of the 2R,3S,4S stereotriad. This study has also revealed that epimerization at C4, results in a substantial enhancement in β-selectivity (up to β/α 300:1). Copyright

Monosaccharidic mimetics of the sialyl LewisX tetrasaccharide based on 2,7-dihydroxynaphthalene

Weck, Stefan,Frank, Martin,Hamann, Alf,Opatz, Till

, p. 134 - 148 (2013/09/24)

A potential monosaccharidic mimetic of the sialyl LewisX tetrasaccharide (sLeX) was identified based on an in silico docking study using the crystal structure of an E-selectin-sLeX complex. The chemical synthesis of the mimetic in an ortho-selective C-glycosylation is described. This compound and two close analogues were evaluated in a cell-based selectin binding assay where none of the tested mimetics showed an IC 50 below 1mM. This result can be explained by an unexpected 1C4 conformation of the mannosyl residue which precludes the required binding of the Ca2+-ion in E-selectin.
