Role of tautomerism of 2-azaadenine and 2-azahypoxanthine in substrate recognition by xanthine oxidase.

J. Comput. Aided Mol. Des. 11(2) , 153-62, (1997)

The tautomerism of 2-azaadenine and 2-hypoxanthine has been examined in the gas phase and in aqueous solution. The tautomerism in the gas phase has been studied by means of semiempirical and ab initio...

Simultaneous determination of dacarbazine, its photolytic degradation product, 2-azahypoxanthine, and the metabolite 5-aminoimidazole-4-carboxamide in plasma and urine by high-pressure liquid chromatography.

Antimicrob. Agents Chemother. 27(6) , 977-9, (1985)

A high-pressure liquid chromatographic method has been developed that allows for the simultaneous analysis of dacarbazine (DTIC), 5-aminoimidazole-4-carboxamide (AIC), and 2-azahypoxanthine (2-AZA) in...

Metabolism and metabolic effects of 2-azahypoxanthine and 2-azaadenosine.

Biochem. Pharmacol. 34(8) , 1293-304, (1985)

The metabolism and metabolic effects of 2-azahypoxanthine and 2-azaadenosine were studied to elucidate the biochemical basis for their known cytotoxicities. 2-Azaadenosine is a known substrate for ade...
