Synthesis and cytotoxic activity of some new 2,6-substituted purines.

A seriesof twenty four acyclic unsaturated 2,6-substututed purines 5a-20b were synthesized. These compounds were evaluated for cytotoxic activity against NCI-60 DTP human tumor cell line screen at 10µMconcentration. N₉-[(Z)-4'-chloro-2'-butenyl-1'-yl]-2,6-dichloropurine(5a), N₉-[4'-chloro-2'-butynyl-1'-yl]-2,6-dichloropurine(10a), N₉-[(E)-2',3'-dibromo-4'-chloro-2'-butenyl-1'-yl]-6-methoxypurin...

Synthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds

3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...

Facile synthesis of 9-substituted 9-deazapurines as potential purine nucleoside phosphorylase inhibitors.

A facile synthesis of 9-substituted 9-deazapurines as potential inhibitors of purine nucleoside phosphorylase has been achieved by the direct Friedel-Crafts aroylation or arylmethylation of 9-deazapurines using trifluoromethanesulfonic acid as catalyst. The aroylated 9-deazapurines could be transformed into the corresponding 9-aryimethyl derivatives by the Wolff-Kishner reaction. A novel synthe...

Stimulation of Lettuce Seed Germination by 6-(Substituted) Purines.

Presoaking several varieties of seed, especially lettuce, in various 6(substituted) aminoand thiopurine solutions has been found to increase their rate of germination (3, 5, 6). Recently it was also reported that these purine derivatives are synergistic with gibberellin in inducing these biological responses whereas gibberellin alone was only moderately active in stimulating germination of Earl...

Chemical synthesis and some properties of 6-substituted flavins.

A number of derivatives of riboflavin and of 3-methyllumiflavin substituted in the 6 position have been synthesized starting with 6-nitro flavins, reduction to the 6-amino flavin, and diazotization, followed by reaction with the appropriate nucleophile. The absorption spectra, oxidation-reduction potentials, and the electron spin resonance spectra of the radical cationic forms of several of the...
