28251-53-8 Usage

General Description

Methyl 2-O,3-O,4-O-triacetyl-6-deoxy-α-L-mannopyranoside is a chemical compound that belongs to the class of methyl glycosides. It is a derivative of α-L-mannopyranoside, with three acetyl groups attached to the 2nd, 3rd, and 4th hydroxyl groups, and a methyl group at the 6th position. Methyl 2-O,3-O,4-O-triacetyl-6-deoxy-α-L-mannopyranoside is commonly used as a building block in the synthesis of complex carbohydrates and glycoconjugates. It is utilized in medicinal and biochemical research for its ability to mimic natural glycosides and for its potential therapeutic applications in drug development and glycobiology.

Check Digit Verification of cas no

The CAS Registry Mumber 28251-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,5 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28251-53:
(7*2)+(6*8)+(5*2)+(4*5)+(3*1)+(2*5)+(1*3)=108
108 % 10 = 8
So 28251-53-8 is a valid CAS Registry Number.

Total synthesis of jadomycins B, S, T, and ILEVS1080

Yang, Xiaoyu,Yu, Biao

, p. 8431 - 8434 (2013/07/19)

Sweetening up jadomycin A: The first total synthesis of jadomycins B, S, T, and ILEVS1080 has been achieved, featuring construction of the unique 8H-benz[b]oxazolo[3,3-f]phenanthridine skeleton by biomimetic condensation of a quinone aldehyde with amino acid sodium salts and elaboration of the glycosides by Mitsunobu condensation (see figure).

A nonself sugar mimic of the HIV glycan shield shows enhanced antigenicity

Antibody 2G12 uniquely neutralizes a broad range of HIV-1 isolates by binding the high-mannose glycans on the HIV-1 surface glycoprotein, gp120. Antigens that resemble these natural epitopes of 2G12 would be highly desirable components for an HIV-1 vaccine. However, host-produced (self)-carbohydrate motifs have been unsuccessful so far at eliciting 2G12-like antibodies that cross-react with gp120. Based on the surprising observation that 2G12 binds nonproteinaceous monosaccharide D-fructose with higher affinity than D-mannose, we show here that a designed set of nonself, synthetic monosaccharides are potent antigens. When introduced to the terminus of the D1 arm of protein glycans recognized by 2G12, their antigenicity is significantly enhanced. Logical variation of these unnatural sugars pinpointed key modifications, and the molecular basis of this increased antigenicity was elucidated using high-resolution crystallographic analyses. Virus-like particle protein conjugates containing such nonself glycans are bound more tightly by 2G12. As immunogens they elicit higher titers of antibodies than those immunogenic conjugates containing the self D1 glycan motif. These antibodies generated from nonself immunogens also cross-react with this self motif, which is found in the glycan shield, when it is presented in a range of different conjugates and glycans. However, these antibodies did not bind this glycan motif when present on gp120.
