5991-01-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5991-01-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,9 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5991-01:
(6*5)+(5*9)+(4*9)+(3*1)+(2*0)+(1*1)=115
115 % 10 = 5
So 5991-01-5 is a valid CAS Registry Number.

Synthesis of 7-Deaza-cyclic Adenosine-5′-diphosphate-carbocyclic-ribose and Its 7-Bromo Derivative as Intracellular Ca2+-Mobilizing Agents

Takano, Satoshi,Tsuzuki, Takayoshi,Murayama, Takashi,Sakurai, Takashi,Fukuda, Hayato,Arisawa, Mitsuhiro,Shuto, Satoshi

, p. 6619 - 6627 (2015)

Cyclic ADP-carbocyclic-ribose (cADPcR, 3) is a biologically and chemically stable equivalent of cyclic ADP-ribose (cADPR, 1), a Ca2+-mobilizing second messenger. We became interested in the biological activity of the 7-deaza analogues of cADPcR, i.e., 7-deaza-cADPcR (7) and its 7-bromo derivative, i.e., 7-deaza-7-Br-cADPcR (8), because 7-deazaadenosine is an efficient bioisostere of adenosine. The synthesis of 7 and 8 required us to construct the key N1-carbocyclic-ribosyl-7-deazaadenosine structure. Therefore, we developed a general method for preparing N1-substituted 7-deazaadenosines by condensing a 2,3-disubstituted pyrrole nucleoside with amines. Using this method, we prepared the N1-carbocyclic ribosyl 7-deazaadenosine derivative 10a, from which we then synthesized the target 7-deaza-cADPcR (7) via an Ag+-promoted intramolecular condensation to construct the 18-membered pyrophosphate ring structure. The corresponding 7-bromo derivative 8, which was the first analogue of cADPR with a substitution at the 7-position, was similarly synthesized. Biological evaluation for Ca2+-mobilizing activity in the sea urchin egg homogenate system indicated that 7-deaza-cADPcR (7) and 7-deaza-7-Br-cADPcR (8) acted as a full agonist and a partial agonist, respectively.

A One-Pot Synthesis of Highly Functionalized Purines

Zelli, Renaud,Zeinyeh, Wa?l,Haudecoeur, Romain,Alliot, Julien,Boucherle, Benjamin,Callebaut, Isabelle,Décout, Jean-Luc

supporting information, p. 6360 - 6363 (2017/12/08)

Highly substituted purines were synthesized in good to high yields through a one-pot straightforward metal-free scalable method, using the Traube synthesis adapted to Vilsmeier-type reagents. From 5-amino-4-chloropyrimidines, new 9-aryl-substituted chloropurines and intermediates for peptide nucleic acid synthesis were prepared. Variant procedures allowing a rapid synthesis of ribonucleosides and 7-benzylpurine from 5-amidino-6-aminopyrimidines are also reported to illustrate the high potential of this versatile toolbox. This route appears to be particularly interesting in the field of nucleic acids for a direct and rapid access to various new 8-alkylpurine nucleosides.

Synthesis of new pyrazoline-nucleoside analogue derivatives

Azouz,Lammara,Benallia,Guenane

, p. 294 - 305 (2013/08/26)

In this work, a synthesis of pyrazoline nucleosides analogues is presented, using the stereospecific sodium salt glycosylation procedure. In the first step, chalcones were prepared using Claisen Schmidt reaction by reacting benzaldehyde with enolizable ketones in ethanolic NaOH solutions. Next, these chalcones were immediately reacted with hydrazine hydrochloridein the presence of dry methanol to obtain the corresponding 2-pyrazolines. Finally, the coupling of the pyrazolines with 1-chloro-arabinofuranose leads to different β-nucleosides as the major product (13-17) in good yields. The structures of these derivatives were characterized by infrared and 1HNMR spectroscopy and mass spectrometry.
