7284-18-6 Usage

General Description

D-Alpha-Chitobiose Octaacetate is a chemical compound derived from chitin, a polysaccharide found in the exoskeletons of crustaceans and insects. It consists of two units of N-acetylglucosamine linked together. D-ALPHA-CHITOBIOSE OCTAACETATE is octaacetated, meaning it has eight acetyl groups attached, which makes it more stable and soluble in organic solvents. D-Alpha-Chitobiose Octaacetate has potential applications in the pharmaceutical and biomedical industries, particularly in drug delivery systems and as a building block for the synthesis of bioactive compounds. It may also have uses in the food industry and in agricultural products, as it has been shown to have antimicrobial and antifungal properties. Overall, this compound has potential as a versatile and useful chemical in various industries.

Check Digit Verification of cas no

The CAS Registry Mumber 7284-18-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,8 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7284-18:
(6*7)+(5*2)+(4*8)+(3*4)+(2*1)+(1*8)=106
106 % 10 = 6
So 7284-18-6 is a valid CAS Registry Number.

Acetylated chitosan oligosaccharides act as antagonists against glutamate-induced PC12 cell death via Bcl-2/Bax signal pathway

Hao, Cui,Gao, Lixia,Zhang, Yiran,Wang, Wei,Yu, Guangli,Guan, Huashi,Zhang, Lijuan,Li, Chunxia

Chitosan oligosaccharides (COSs), depolymerized products of chitosan composed of β-(1→4) D-glucosamine units, have broad range of biological activities such as antitumour, antifungal, and antioxidant activities. In this study, peracetylated chitosan oligosaccharides (PACOs) and N-acetylated chitosan oligosaccharides (NACOs) were prepared from the COSs by chemcal modification. The structures of these monomers were identified using NMR and ESI-MS spectra. Their antagonist effects against glutamate-induced PC12 cell death were investigated. The results showed that pretreatment of PC12 cells with the PACOs markedly inhibited glutamate-induced cell death in a concentration-dependent manner. The PACOs were better glutamate antagonists compared to the COSs and the NACOs, suggesting the peracetylation is essential for the neuroprotective effects of chitosan oligosaccharides. In addition, the PACOs pretreatment significantly reduced lactate dehydrogenase release and reactive oxygen species production. It also attenuated the loss of mitochondrial membrane potential. Further studies indicated that the PACOs inhibited glutamate-induced cell death by preventing apoptosis through depressing the elevation of Bax/Bcl-2 ratio and caspase-3 activation. These results suggest that PACOs might be promising antagonists against glutamate-induced neural cell death.

Probing the mechanism of a fungal glycosyltransferase essential for cell wall biosynthesis. UDP-Chitobiose is not a substrate for chitin synthase

Chang, Robert,Yeager, Adam R.,Finney, Nathaniel S.

, p. 39 - 41 (2007/10/03)

Chitin synthase is responsible for the biosynthesis of chitin, an essential component of the fungal cell wall. There is a long-standing question as to whether "processive" transferases such as chitin synthase operate in the same manner as non-processive transferases. The question arises from analysis of the polysaccharide structure - in chitin, for instance, each sugar residue is rotated ca. 180 deg relative to the preceding sugar in the chain. This requires that the enzyme account for the alternating "up/down" configuration during biosynthesis. An enzyme with a single active site, analogous to the non-processive transferases - would have to accommodate a distorted glycosidic linkage at every other synthetic step. An alternative proposal is that the enzyme might assemble the disaccharide donor, addressing the "up/down" conformational problem prior to polymer synthesis. We present compelling evidence that this latter hypothesis is incorrect.
