93302-26-2 Usage

General Description

Methyl-D-galactopyranoside, also known as methyl galactoside, is a chemical compound derived from galactose, a type of sugar. It belongs to the group of glycosides, which are molecules composed of a sugar and a non-sugar component. Methyl-D-galactopyranoside is commonly used in the laboratory as a substrate for enzymes that hydrolyze glycosides, making it a valuable tool for studying carbohydrate metabolism and glycosylation processes. It is also utilized in the production of various pharmaceuticals, as well as in the food industry for flavoring and sweetening applications. Additionally, it has potential applications in the development of new biomaterials and as a precursor for the synthesis of more complex galactopyranoside derivatives.

Check Digit Verification of cas no

The CAS Registry Mumber 93302-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,0 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93302-26:
(7*9)+(6*3)+(5*3)+(4*0)+(3*2)+(2*2)+(1*6)=112
112 % 10 = 2
So 93302-26-2 is a valid CAS Registry Number.

Carbon glycoside glycosylated tetravalent platinum compound as well as synthesis method and application thereof

-

Paragraph 0064-0067, (2021/07/08)

The invention provides a carbon glycoside glycosylated tetravalent platinum compound, a synthesis method and application thereof. R1 and R2 are independently C1-C4 lower alkanes, R3 is glucose, galactose, mannose and ribose, different sugars are used as raw materials, and a series of carbon glycoside glycosylated tetravalent platinum compounds are synthesized through protection and deprotection reaction and metallization reaction of the sugars. The synthesis method is simple, the used raw materials are cheap and easy to obtain, the glycosylated tetravalent platinum compound has the capacity of targeting glucose transporter protein and has potential application value in the field of cancer treatment, introduction of a C-glucosidic bond enables the series of compounds to have the capacity of resisting hydrolysis of beta-glucosidase, and the compound is expected to be applied to the field of oral antitumor drugs.

Structure of the unusual Sinorhizobium fredii HH103 lipopolysaccharide and its role in symbiosis

, p. 10969 - 10987 (2021/01/07)

Rhizobia are soil bacteria that form important symbiotic associations with legumes, and rhizobial surface polysaccharides, such as K-antigen polysaccharide (KPS) and lipopolysaccharide (LPS), might be important for symbiosis. Previously, we obtained a mutant of Sinorhizobium fredii HH103, rkpA, that does not produce KPS, a homopolysaccharide of a pseudaminic acid derivative, but whose LPS electrophoretic profile was indistinguishable from that of the WT strain. We also previously demonstrated that the HH103 rkpLMNOPQ operon is responsible for 5-acetamido-3,5,7,9-tetradeoxy-7-(3-hydroxybutyramido)-L-glyc-ero-L-manno-nonulosonic acid [Pse5NAc7(3OHBu)] production and is involved in HH103 KPS and LPS biosynthesis and that an HH103 rkpM mutant cannot produce KPS and displays an altered LPS structure. Here, we analyzed the LPS structure of HH103 rkpA, focusing on the carbohydrate portion, and found that it contains a highly heterogeneous lipid A and a peculiar core oligosaccharide composed of an unusually high number of hexuronic acids containing b-configured Pse5NAc7(3OHBu). This pseudaminic acid derivative, in its a-configuration, was the only structural component of the S. fredii HH103 KPS and, to the best of our knowledge, has never been reported from any other rhizobial LPS. We also show that Pse5NAc7(3OHBu) is the complete or partial epitope for a mAb, NB6-228.22, that can recognize the HH103 LPS, but not those of most of the S. fredii strains tested here. We also show that the LPS from HH103 rkpM is identical to that of HH103 rkpA but devoid of any Pse5NAc7(3OHBu) residues. Notably, this rkpM mutant was severely impaired in symbiosis with its host, Macroptilium atropurpureum.

From d-to l-Monosaccharide Derivatives via Photodecarboxylation-Alkylation

Wan, I. C. Steven,Witte, Martin D.,Minnaard, Adriaan J.

supporting information, p. 7669 - 7673 (2019/10/08)

Photodecarboxylation-alkylation of conformationally locked monosaccharides leads to inversion of stereochemistry at C5. This allows the synthesis of l-sugars from their readily available d-counterparts. Via this strategy, methyl l-guloside was synthesized from methyl d-mannoside in 21% yield over six steps.
