Check Digit Verification of cas no

The CAS Registry Mumber 19234-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19234-66:
(7*1)+(6*9)+(5*2)+(4*3)+(3*4)+(2*6)+(1*6)=113
113 % 10 = 3
So 19234-66-3 is a valid CAS Registry Number.

Potent SARS-CoV-2 mRNA Cap Methyltransferase Inhibitors by Bioisosteric Replacement of Methionine in SAM Cosubstrate

Bobi?eva, Olga,Bobrovs, Raitis,Ka?epe, Iveta,Patetko, Liene,Kalni??, Gints,?i?ovs, Mihails,Bula, Anna L.,Grī Nberga, Solveiga,Borodu??is, Mā Rti??,Ramata-Stunda, Anna,Rostoks, Nils,Jirgensons, Aigars,Tā Rs, Kaspars,Jaudzems, Kristaps

Viral mRNA cap methyltransferases (MTases) are emerging targets for the development of broad-spectrum antiviral agents. In this work, we designed potential SARS-CoV-2 MTase Nsp14 and Nsp16 inhibitors by using bioisosteric substitution of the sulfonium and amino acid substructures of the cosubstrate S-adenosylmethionine (SAM), which serves as the methyl donor in the enzymatic reaction. The synthetically accessible target structures were prioritized using molecular docking. Testing of the inhibitory activity of the synthesized compounds showed nanomolar to submicromolar IC50 values for five compounds. To evaluate selectivity, enzymatic inhibition of the human glycine N-methyltransferase involved in cellular SAM/SAH ratio regulation was also determined, which indicated that the discovered compounds are nonselective inhibitors of the studied MTases with slight selectivity for Nsp16. No cytotoxic effects were observed; however, this is most likely a result of the poor cell permeability of all evaluated compounds.

Synthesis of 5'-N-(2-[18F]Fluoroethyl)-carboxamidoadenosine: A promising tracer for investigation of adenosine receptor system by PET technique

, p. 807 - 815 (2000)

5'-N-(2-[18F]Fluoroethyl)-carboxainidoadenosine ([18F]FNECA), a promising 18F-labelled adenosine agonist has been prepared by two different synthetic routes. In the first, [18F]fluoride was reacted with 5'-N,N-ethylene-2',3'-O-isopropylidenecarboxamido-adenosine and after removing the protective group [18F]FNECA was obtained in a low radiochemical yield (1 ± 1%, mean ± sd, n = 7, decay corrected). In the second, 2-[18F]fluoroethylamine was synthesised according to the literature and reacted with 2',3'-O-isopropylideneadenosine-5'-uronic acid in the presence of a coupling agent. The following hydrolysis step provided the [18F]FNECA with a modest radiochemical yield (24 ± 9%, n = 17, based on [18F]fluoride-activity). After purification by preparative reverse phase HPLC 18.9-166.5 MBq (0.51-4.5 mCi) [18F]FNECA was obtained with a specific activity of 2.35 ± 1.14 TBq/mmol (63.5 ± 30.9 Ci/mmol, n = 3). The total synthesis took 200 min and the decay corrected radiochemical yield based on [18F]F- activity was 17 ± 9% (n = 5) with more than 99.9% radiochemical purity. This second route provides sufficient [18F]FNECA for the subsequent biological evaluation using PET-technique.

Tethering small molecules to a phage display library: Discovery of a selective bivalent inhibitor of protein kinase A

Meyer, Scott C.,Shomin, Carolyn D.,Gaj, Thomas,Ghosh, Indraneel

, p. 13812 - 13813 (2007)

We report a noncovalent tethering methodology for the fragment-based selection of bivalent ligands targeting protein kinases. In this approach, a small-molecule warhead, staurosporine, directs a phage display cyclic peptide library to the active site of cAMP-dependent protein kinase (PKA), allowing for targeted library enrichment. A cyclic peptide discovered through this selection, when covalently attached to a staurosporine derivative, displayed a 90-fold increase in affinity for PKA. Moreover, the bivalent inhibitor was shown to be significantly more selective than the starting warhead when tested against a small panel of kinases. Thus our general methodology allows for covalent linkage of known small-molecule ligands to biological libraries for discovering potent bivalent inhibitors of biological targets. Copyright

Deamination of 2′,3′-O-isopropylideneadenosine-5′- carboxylic acid catalyzed by adenosine deaminase (ADA) and adenylate deaminase (AMPDA): Influence of substrate ionization on the activity of the enzymes

Ciuffreda, Pierangela,Alessandrini, Laura,Pavlovic, Radmila,Santaniello, Enzo

, p. 121 - 127 (2007)

Adenosine deaminase (ADA) and adenylate deaminase (AMPDA) catalyze the deamination of 2′,3′-O-isopropylideneadenosine-5′-carboxylic acid to the corresponding inosine derivative and dependence of the rate of enzymatic reaction on the ionization degree of the substrate has been studied at different pH values.
