Temozolomide Acid (TMZA) is a metabolite of temozolomide (TMZ). Temozolomide processes anticancer activity in vitro. Temozolomide (TMZ) is an oral alkylating agent used to treat glioblastoma multiforme (GBM) and astrocytomas.

Aroplatin is a synthetic liposomal formulation of bis-neodecanoate diaminocyclohexane platinum (NDDP), a third-generation platinum complex analogue of cisplatin, with potential antineoplastic activity. After displacement of the 2 long-chain aliphatic leaving groups (neodecanoic acid), platinum diaminocyclohexane (DACH) complexes become highly reactive and alkylate macromolecules, forming both inter- and intra-strand DNA crosslinks and inhibiting DNA synthesis, which results in tumor cell cytotoxicity. Because DNA mismatch-repair (MMR) complexes do not recognize DACH–platinum adducts, DNA repair mechanisms are inhibited, overcoming limitations observed with other platinum-based agents. In addition, the liposomal encapsulation improves the bioavailability of NDDP and reduces its toxicity profile.

TriN2755 is a synthetic triazene derivative with antineoplastic activity. Upon metabolic activation via N-demethylation, TriN2755 is converted into highly reactive carbocations that can alkylate DNA and other macromolecules, thereby resulting in DNA cross links, inhibiting DNA replication and repair, and subsequently inducing apoptosis. This agent has high hydrophilicity and photostability and shows a favorable toxicity profile over the other triazenes.

Apaziquone has potential antineoplastic and radiosensitization activities. It is converted to active metabolites in hypoxic cells by intracellular reductases, which are present in greater amounts in hypoxic tumor cells. The active metabolites alkylate DNA
