Check Digit Verification of cas no

The CAS Registry Mumber 943858-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,8,5 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 943858-70:
(8*9)+(7*4)+(6*3)+(5*8)+(4*5)+(3*8)+(2*7)+(1*0)=216
216 % 10 = 6
So 943858-70-6 is a valid CAS Registry Number.

Template-directed oligonucleotide strand ligation, covalent intramolecular DNA circularization and catenation using click chemistry

Kumar, Ravindra,El-Sagheer, Afaf,Tumpane, John,Lincoln, Per,Wilhelmsson, L. Marcus,Brown, Tom

, p. 6859 - 6864 (2007)

The copper-catalyzed azide-alkyne cycloaddition reaction has been used for the template-mediated chemical ligation of two oligonucleotide strands, one with a 5′-alkyne and the other with a 3′-azide, to produce a DNA strand with an unnatural backbone at the ligation point. A template-free click-ligation reaction has been used for the intramolecular circularization of a single stranded oligonucleotide which was used as a template for the synthesis of a covalently closed DNA catenane.

Integrin αvβ3-Targeted [64Cu]CuS Nanoparticles for PET/CT Imaging and Photothermal Ablation Therapy

Cui, Lili,Xiong, Chiyi,Zhou, Min,Shi, Sixiang,Chow, Diana S-L.,Li, Chun

, p. 4062 - 4071 (2018)

Copper sulfide (CuS) nanoparticles have been considered one of the most clinical relevant nanosystems because of their straightforward chemistry, small particle size, low toxicity, and intrinsic theranostic characteristics. In our previous studies, radioactive [64Cu]CuS nanoparticles were successfully developed to be used as efficient radiotracers for positron emission tomography and for photothermal ablation therapy of cancer cells using near-infrared laser irradiation. However, the major challenge of CuS nanoparticles as a theranostic platform is the lack of a means for effective targeted delivery to the tumor site. To overcome this challenge, we designed and synthesized angiogenesis-targeting [64Cu]CuS nanoparticles, which are coupled with cyclic RGDfK peptide [c(RGDfK)] through polyethylene glycol (PEG) linkers using click chemistry. In assessing their tumor-targeting efficacy, we found that the tumor uptakes of [64Cu]CuS-PEG-c(RGDfK) nanoparticles at 24 h after intravenous injection were significantly greater (8.6% ± 1.4% injected dose/gram of tissue) than those of nontargeted [64Cu]CuS-PEG nanoparticles (4.3% ± 1.2% injected dose/gram of tissue, p 64Cu]CuS-PEG-c(RGDfK) nanoparticles induced 98.7% necrotic areas. In contrast, irradiation of tumors in mice administered nontargeted CuS-PEG nanoparticles induced 59% necrotic areas (p 64Cu]CuS nanoparticles may serve as a promising platform for image-guided ablation therapy with high efficacy and minimal side effects in future clinical translation of this novel class of multifunctional nanomaterials.

Aspartic Acid Side-Chain Benzyl Ester as a Multifunctionalization Precursor for Synthesis of Branched and Cyclic Arginylglycylaspartic Acid Peptides

Tian, Xiaobo,Yu, Pengqiu,Tang, Yubo,Le, Zhiping,Huang, Wei

, p. 1966 - 1970 (2017)

Here, we report a peptide aspartic acid side-chain benzyl ester as a useful precursor that can be efficiently converted into various functional groups, including acid, amide, carbonyl hydrazide, carbonyl azide, or thio ester groups, without other protection for the peptide. With this strategy, we synthesized a series of novel branched and cyclic arginylglycylaspartic acid peptides through successive peptide C-terminal ligation and side-chain ligation based on a side-chain carbonyl azide or thio ester.

An RNA splicing enhancer that does not act by looping

Lewis, Helen,Perrett, Andrew J.,Burley, Glenn A.,Eperon, Ian C.

, p. 9800 - 9803 (2012)

Out of the loop: Do the proteins bound to an enhancer site on pre-mRNA interact directly with the splice site by diffusion (looping), as is generally accepted, or does the intervening RNA play a role (see scheme)? By inserting a PEG linker between an enhancer sequence and alternative splice sites, the interaction of these two elements can be studied. Intervening RNA was essential for the enhancer activity, which rules out the looping model. Copyright

Phosphorylation-Inducing Chimeric Small Molecules

Small molecules have been classically developed to inhibit enzyme activity; however, new classes of small molecules that endow new functions to enzymes via proximity-mediated effect are emerging. Phosphorylation (native or neo) of any given protein-of-interest can alter its structure and function, and we hypothesized that such modifications can be accomplished by small molecules that bring a kinase in proximity to the protein-of-interest. Herein, we describe phosphorylation-inducing chimeric small molecules (PHICS), which enable two example kinases - AMPK and PKC - to phosphorylate target proteins that are not otherwise substrates for these kinases. PHICS are formed by linking small-molecule binders of the kinase and the target protein, and exhibit several features of a bifunctional molecule, including the hook-effect, turnover, isoform specificity, dose and temporal control of phosphorylation, and activity dependent on proximity (i.e., linker length). Using PHICS, we were able to induce native and neo-phosphorylations of BRD4 by AMPK or PKC. Furthermore, PHICS induced a signaling-relevant phosphorylation of the target protein Bruton's tyrosine kinase in cells. We envision that PHICS-mediated native or neo-phosphorylations will find utility in basic research and medicine.

Design and synthesis of novel dual-cyclic RGD peptides for αvβ3 integrin targeting

Liu, Junjie,Cheng, Xiaozhong,Tian, Xiaobo,Guan, Dongliang,Ao, Jiwei,Wu, Zhimeng,Huang, Wei,Le, Zhiping

supporting information, p. 896 - 900 (2019/02/07)

The specific binding of RGD cyclic peptide with integrin αvβ3 attracts great research interest for tumor-targeting drug delivery. Herein, we designed and synthesized a series of dual-ring RGD-peptide derivatives as a drug carrier for αvβ3 targeting. Three novel peptides showed excellent cell adhesion inhibition effect, in which, P3 exhibited 7-fold enhancement in IC50 compared with cyclo(RGDfK). Drug-loaded cytotoxicity experiment and imaging experiment indicated that such dual-cyclic RGD peptides have good tumor targeting effects. This work provides a new strategy for the design of novel RGD peptides.
