1198-82-9 Usage

General Description

Methyl 6-deoxy-.beta.-D-galactopyranoside is a chemical compound that belongs to the class of glycosides. It is derived from galactose, a type of sugar. .beta.-D-Galactopyranoside, methyl 6-deoxy- consists of a galactose molecule linked to a methyl group and is a common substrate used in enzymatic assays to study the activity of glycosidases. Methyl 6-deoxy-.beta.-D-galactopyranoside has been studied for its potential applications in the food and pharmaceutical industries due to its properties as a sweetener and its potential medicinal properties. It is also used in research and development in the fields of biochemistry, molecular biology, and biotechnology due to its specific interactions with enzymes and receptor proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 1198-82-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1198-82:
(6*1)+(5*1)+(4*9)+(3*8)+(2*8)+(1*2)=89
89 % 10 = 9
So 1198-82-9 is a valid CAS Registry Number.

Modular Total Synthesis and Cell-Based Anticancer Activity Evaluation of Ouabagenin and Other Cardiotonic Steroids with Varying Degrees of Oxygenation

Khatri, Hem Raj,Bhattarai, Bijay,Kaplan, Will,Li, Zhongzheng,Curtis Long, Marcus John,Aye, Yimon,Nagorny, Pavel

supporting information, p. 4849 - 4860 (2019/03/26)

A Cu(II)-catalyzed diastereoselective Michael/aldol cascade approach is used to accomplish concise total syntheses of cardiotonic steroids with varying degrees of oxygenation including cardenolides ouabagenin, sarmentologenin, 19-hydroxysarmentogenin, and 5-epi-panogenin. These syntheses enabled the subsequent structure activity relationship (SAR) studies on 37 synthetic and natural steroids to elucidate the effect of oxygenation, stereochemistry, C3-glycosylation, and C17-heterocyclic ring. Based on this parallel evaluation of synthetic and natural steroids and their derivatives, glycosylated steroids cannogenol-l-α-rhamnoside (79a), strophanthidol-l-α-rhamnoside (92), and digitoxigenin-l-α-rhamnoside (97) were identified as the most potent steroids demonstrating broad anticancer activity at 10-100 nM concentrations and selectivity (nontoxic at 3 μM against NIH-3T3, MEF, and developing fish embryos). Further analyses indicate that these molecules show a general mode of anticancer activity involving DNA-damage upregulation that subsequently induces apoptosis.

Synthesis of β-(1→2)-Linked 6-Deoxy- l -altropyranose Oligosaccharides via Gold(I)-Catalyzed Glycosylation of an ortho-Hexynylbenzoate Donor

Shen, Zhengnan,Mobarak, Hani,Li, Wei,Widmalm, G?ran,Yu, Biao

, p. 3062 - 3071 (2017/03/23)

The β-(1→2)-linked 6-deoxy-l-altropyranose di- to pentasaccharides 2-5, relevant to the O-antigen of the infectious Yersinia enterocolitica O:3, were synthesized for the first time. The challenging 1,2-cis-altropyranosyl linkage was assembled effectively via glycosylation with 2-O-benzyl-3,4-di-O-benzoyl-6-deoxy-l-altropyranosyl ortho-hexynylbenzoate (7) under the catalysis of PPh3AuNTf2. NMR and molecular modeling studies showed that the pentasaccharide (5) adopted a left-handed helical conformation.

Catalytic and regioselective oxidation of carbohydrates to synthesize keto-sugars under mild conditions

Muramatsu, Wataru

, p. 4846 - 4849 (2015/04/27)

A new catalytic and regioselective approach for the synthesis of keto-sugars is described. An organotin catalyst, Oc2SnCl2, in the presence of trimethylphenylammonium tribromide ([TMPhA]+Br3-) accelerates the regioselective oxidation at the axial -OH group of 1,2-diol moieties in galactopyranosides. The reaction conditions can also be used for the regioselective oxidation of various carbohydrates.
