Check Digit Verification of cas no

The CAS Registry Mumber 76375-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,7 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76375-60:
(7*7)+(6*6)+(5*3)+(4*7)+(3*5)+(2*6)+(1*0)=155
155 % 10 = 5
So 76375-60-5 is a valid CAS Registry Number.

Synthesis and biological evaluation of 3β-O-neoglycosides of caudatin and its analogues as potential anticancer agents

Li, Xiao-San,Chen, Tang-Ji,Xu, Zhi-Peng,Long, Juan,He, Miao-Ying,Zhan, He-Hui,Zhuang, Hai-Cai,Wang, Qi-Lin,Liu, Li,Yang, Xue-Mei,Tang, Jin-Shan

, (2021/12/30)

In order to study the structure–activity relationship (SAR) of C21-steroidal glycosides toward human cancer cell lines and explore more potential anticancer agents, a series of 3β-O-neoglycosides of caudatin and its analogues were synthesized. The results revealed that most of peracetylated 3β-O-monoglycosides demonstrated moderate to significant antiproliferative activities against four human cancer cell lines (MCF-7, HCT-116, HeLa, and HepG2). Among them, 3β-O-(2,3,4-tri-O-acetyl-β-L-glucopyranosyl)-caudatin (2k) exhibited the highest antiproliferative activity aganist HepG2 cells with an IC50 value of 3.11 μM. Mechanical studies showed that compound 2k induced both apoptosis and cell cycle arrest at S phase in a dose dependent manner. Overall, these present findings suggested that glycosylation is a promising scaffold to improve anticancer activity for naturally occurring C21-steroidal aglycones, and compound 2k represents a potential anticancer agent deserved further investigation.

A silyl ether-protected building block forO-GlcNAcylated peptide synthesis to enable one-pot acidic deprotection

Yan, Bingjia,Li, Wenyi,Hackenberger, Christian P. R.

supporting information, p. 8014 - 8017 (2021/10/04)

In this report, we introduce a novel building block for Fmoc/tBu solid phase peptide synthesis (SPPS) of β-linkedO-GlcNAcylated peptides. This building block carries acid labile silyl ether protecting groups, which are fully removed under TFA-mediated peptide cleavage conditions from the resin, thus requiring fewer synthetic steps and no intermediate purification as compared to other acid or base labile protecting group strategies.

Synthesis of Asparagine Derivatives Harboring a Lewis X Type DC-SIGN Ligand and Evaluation of their Impact on Immunomodulation in Multiple Sclerosis

Doelman, Ward,Marqvorsen, Mikkel H. S.,Chiodo, Fabrizio,Bruijns, Sven C. M.,van der Marel, Gijsbert A.,van Kooyk, Yvette,van Kasteren, Sander I.,Araman, Can

The protein myelin oligodendrocyte glycoprotein (MOG) is a key component of myelin and an autoantigen in the disease multiple sclerosis (MS). Post-translational N-glycosylation of Asn31 of MOG seems to play a key role in modulating the immune response towards myelin. This is mediated by the interaction of Lewis-type glycan structures in the N-glycan of MOG with the DC-SIGN receptor on dendritic cells (DCs). Here, we report the synthesis of an unnatural Lewis X (LeX)-containing Fmoc-SPPS-compatible asparagine building block (SPPS=solid-phase peptide synthesis), as well as asparagine building blocks containing two LeX-derived oligosaccharides: LacNAc and Fucα1-3GlcNAc. These building blocks were used for the glycosylation of the immunodominant portion of MOG (MOG31-55) and analyzed with respect to their ability to bind to DC-SIGN in different biological setups, as well as their ability to inhibit the citrullination-induced aggregation of MOG31-55. Finally, a cytokine secretion assay was carried out on human monocyte-derived DCs, which showed the ability of the neoglycopeptide decorated with a single LeX to alter the balance of pro- and anti-inflammatory cytokines, inducing a tolerogenic response.

Protein S-Glyco-Modification through an Elimination-Addition Mechanism

Qin, Ke,Zhang, Hao,Zhao, Zhenqi,Chen, Xing

supporting information, p. 9382 - 9388 (2020/06/04)

Per-O-acetylated unnatural monosaccharides containing a bioorthogonal group have been widely used for metabolic glycan labeling (MGL) in live cells for two decades, but it is only recently that we discovered the existence of an artificial "S-glycosylation" between protein cysteines and per-O-acetylated sugars. While efforts are being made to avoid this nonspecific reaction in MGL, the reaction mechanism remains unknown. Here, we present a detailed mechanistic investigation, which unveils the "S-glycosylation" being an atypical glycosylation termed S-glyco-modification. In alkaline protein microenvironments, per-O-acetylated monosaccharides undergo base-promoted β-elimination to form thiol-reactive α,β-unsaturated aldehydes, which then react with cysteine residues via Michael addition. This S-glyco-modification produces 3-thiolated sugars in hemiacetal form, rather than typical glycosides. The elimination-addition mechanism guides us to develop 1,6-di-O-propionyl-N-azidoacetylgalactosamine (1,6-Pr2GalNAz) as an improved unnatural monosaccharide for MGL.

A terpyridine zinc complex for selective detection of lipid pyrophosphates: A model system for monitoring bacterial O- And N-transglycosylations

Fang, Jim-Min,Hsu, Tse-Wei,Hsu, Hsin-Chuan,Chan, Hsin-Yu

, p. 12747 - 12753 (2020/11/10)

To develop an effective method for probing O- and Nglycosyltransfer reactions that are accompanied by the release of undecaprenyl pyrophosphate, solanesyl pyrophosphate (SPP) is used as a surrogate to bind a terpyridine zinc complex (Tpy-Zn), forming a fluorescent [Tpy-Zn]-SPP complex (Kass 106,000 M-1 in EtOH-CHCl3) with 5.8 μM LOD in HEPES buffer (10 mM, pH 7.4) containing 10 mM CaCl2 and 0.08% decyl PEG, which is similar to the bioassay conditions for lipid II polymerization.

Pseudo-enantiomeric carbohydrate-based N-heterocyclic carbenes as promising chiral ligands for enantiotopic discrimination

Bower, John F.,Galan, M. Carmen,Henderson, Alexander S.

supporting information, p. 3012 - 3016 (2020/05/08)

The practical synthesis of carbohydrate-based NHC-Rh complexes bearing C1 or C3 sterically differentiated positions, accessed by glycosylation or SNAr strategies, is reported. These catalysts exhibit pseudo-enantiomeric behaviour in the hydrosilylation of acetophenone. We show that steric bulk at C1 gives preference for (S)-phenyl-1-ethanol, while bulk at C3 leads to the (R)-enantiomer. These results represent the first example of pseudo-enantiomeric carbohydrate-based NHC ligands leading to enantiotopic discrimination.

SYNTHESIS OF DISACCHARIDE BLOCKS FROM NATURAL POLYSACCHARIDES FOR HEPARAN SULFATE OLIGOSACCHARIDE ASSEMBLY

-

Paragraph 0009; 0108; 0118; 0123-0124, (2020/07/14)

Methods for the preparation of oligosaccharide products from polysaccharide starting materials are disclosed. The methods include: hydrolyzing a glucosamine-containing polysaccharide starting material, such as heparin or heparosan, under conditions sufficient to form an oligosaccharide intermediate (e.g., a GlcN-IdoA disaccharide intermediate or a GlcA-GlcN disaccharide intermediate), and converting the oligosaccharide intermediate to the oligosaccharide product. Conversion of the oligosaccharide intermediates to the oligosaccharide products may include one or more esterification, acylation, epimerization, protection, and deprotection steps. Preparation of higher-order oligomers is described, as well as methods for selective oligosaccharide sulfation.
