Chemico-biological interactions, 58(3), 319-331 (1986-06-01)
Decomposition of the antitumor agent 5-(3,3-dimethyl-1-triazeno)imidazole-4-carboxamide (DTIC, Dacarbazine) produces several potentially toxic compounds, the concentration of which depend on incubation parameters such as pH, temperature and illumination. The action of DTIC on chinese hamster ovary (CHO) cell clone formation in

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 plasma or urine. Plasma samples were prepared by ultrafiltration, whereas urine samples were filtered and diluted for

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 adenosine kinase. That 2-azahypoxanthine is a substrate for hypoxanthine (guanine) phosphoribosyltransferase is shown by
B Hernández et al.
Journal of computer-aided molecular design, 11(2), 153-162 (1997-03-01)
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 quantum-mechanical computations, as well as density-functional calculations.
