Temozolomide was launched for the first time in the UK for the treatment of patients with glioblastoma multiforme showing recurrence or progression after standard therapy. It can be considered as a cyclic variant of highly reactive triazenes producing a cascade of ionic or radical antitumoral species. Temozolamide is a 3-methyl analog of mitozolomide and was shown to be converted to cytotoxic triazene MCTIC. It can be prepared in 2 steps from 5- aminoimidazole-4-carboxamide by diazotization then cyclization with methylisocyanate. Mechanistically, the depletion of O6-alkylguanine-DNA alkyltransferase (OGAT) in cells or tumors was shown to be correlated with the cytotoxicity of temozolomide which is a potent inhibitor of this enzyme involved in DNA repair activity. Further approval applications for the treatment of other malignant gliomas such as relapsed anaplastic astrocytoma, advanced metastatic melanoma were submitted.
