51998-91-5 Usage

Uses

2-Benzylthio-6-chloropurine is found in studies of 2-(benzylsulfanyl)-6-chloro-9-isopropylpurine and its uses as a valuable intermediate in the synthesis of diaminopurine cyclin dependent kinase (CDK) inhibitors.

Check Digit Verification of cas no

The CAS Registry Mumber 51998-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51998-91:
(7*5)+(6*1)+(5*9)+(4*9)+(3*8)+(2*9)+(1*1)=165
165 % 10 = 5
So 51998-91-5 is a valid CAS Registry Number.

Substituted 6-(Benzylamino) Purine Riboside Derivatives, Use Thereof and Compositions Containing These Derivatives

-

, (2012/04/04)

The invention relates to 2-substituted-6-(substituted benzylamino)purine riboside derivatives of the general formula I. These compounds possess antiapoptotic, anti-inflammatory and differentiating activities. The invention relates also to the compositions, which contain these derivatives as active ingredients.

SUBSTITUTED 6-ANILINOPURINE DERIVATIVES AS INHIBITORS OF CYTOKININ OXIDASE/DEHYDROGENASE AND PREPARATIONS CONTAINING THESE DERIVATIVES

-

Page/Page column 8, (2010/08/07)

The invention relates to substituted 6-anilinopurine derivatives of the general formula I, wherein R denotes one to five substituents independently selected from the group consisting of hydrogen, halogen, hydroxyl, amino, alkyloxy and alkyl group, and R2 denotes amino, halogen, nitro, thio, alkylthio or alkyl group for use as inhibitors of cytokinin oxidase/dehydrogenase. The invention also relates to the compositions containing these derivatives.

New N6-substituted 8-alkyl-2-phenylmethylsulfanyl-adenines. II [1]

, p. 581 - 585 (2007/10/03)

Title compounds bearing substituents on C(2), C(6) and C(8) were prepared from a newly synthesized pyrimidine derivative 11. The new pyrimidine 11 was generated from compound 2 through two different synthetic schemes. In one pathway, compound 2 was nitrosated, reduced and alkylated to produce compounds 9, 10 and 11 respectively (Scheme). In an alternate route using compound 2 as the starting material, a coupling reaction using the diazonium salt derived from p-methylaniline afforded the azo derivative 7, which was subsequently alkylated and reductively cleaved to form compounds 8 and 11 respectively (See Scheme). Compound 11 was annulated to the corresponding hypoxanthine derivatives 12-14; compounds 12 and 13 were chlorinated with phosphorus oxychloride, then reacted with amines to yield compound 17 and 20 respectively. Compounds 21, 22 and 23 were obtained by oxidation of the corresponding sulfide as depicted in Scheme. Alkylation of the thiol function of 1 gave a mixture of 3 and 4. Compound 3 was chlorinated to 5. Nitration of 5 resulted in electrophilic aromatic substitution of the aryl ring and concomitant oxidation of the sulfide to the sulfoxide, producing 6.
