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
Doxorubicin is a cytotoxic anthracycline antibiotic isolated from cultures of Streptomyces peucetius var. caesius along side with daunorubicin, another cytotoxic agent, in 1970.[A1575,A257709,A257614] Although they both have aglyconic and sugar moieties, doxorubicin's side chain terminates with a primary alcohol group compared to the methyl group of daunorubicin. Although its detailed molecular mechanisms have yet to be understood, doxorubicin is generally thought to exert its effect through DNA intercalation, which eventually leads to DNA damage and the generation of reactive oxygen species. Thanks to its efficacy and broad effect, doxorubicin was approved by the FDA in 1974 to treat a variety of cancer, including but not limited to breast, lung, gastric, ovarian, thyroid, non-Hodgkin’s and Hodgkin’s lymphoma, multiple myeloma, sarcoma, and pediatric cancers.[A1573,A257614,L45231] However, one of the major side effects of doxorubicin is cardiotoxicity, which excludes patients with poor heart function and requires treatment termination once the maximally tolerated cumulative dose is reached.
