Disease relevance of Diazo-ica

  • Toxicity of DTIC in these experiments appears to reflect rapid accumulation of the immediate photodecomposition product of the drug, 4-diazoimidazole-5-carboxamide (DZC), since HGPRT-deficient cells are not resistant to DTIC under these conditions [1].
  • 4-Diazoimidazole-5-carboxamide demonstrated dose-related mutagenicity in Salmonella typhimurium TA 100 and represents a potent electrophilic reactant similar to the proposed ultimate carcinogenic forms of arylalkylnitrosamines and arylnitrosamides [2].
