Refractory anaplastic astrocytoma (WHO grade III) and Glioblastoma multiforme (WHO grade IV) are primary malignant brain tumours with poor prognosis and limited treatment options. Despite considerable genetic heterogeneity, these tumours often have impaired DNA repair systems, rendering them initially sensitive to alkylating agents, although they invariably develop resistance to these agents over time.[A229848, A229858, L32033] Temozolomide is an imidazotetrazine prodrug that is stable at acidic pH but undergoes spontaneous nonenzymatic hydrolysis at neutral or slightly basic pH; these properties allow for both oral and intravenous administration.[A229853, A229888, A229923, L32033] Following initial hydrolysis, further reactions liberate a highly reactive methyl diazonium cation capable of methylating various residues on adenosine and guanine bases leading to DNA lesions and eventual
Azathioprine is a prodrug of 6-mercaptopurine, first synthesized in 1956 by Gertrude Elion, William Lange, and George Hitchings in an attempt to produce a derivative of 6-mercaptopurine with a better therapeutic index.[A189678,A189687,A189690] Azathioprine is used to treat inflammatory conditions like rheumatoid arthritis and as an immunosuppressant in the prevention of renal transplant rejection. Azathiprine was granted FDA approval on 20 March 1968.
