Its lack of antitumor action was attributed to its polarity and to the resulting poor uptake of this hydrophilic chemical. Diazo-IC was then coupled with dimethylamine, yielding 5, (3, 3-dimethyl l-triazeno)imidazole-4-carboxamide) (DTIC) with the intention of obtaining a less polar and more lipophil | Triazenes by Tullio Giraldi, Paperback | Indigo Chapters
