Temozolomide is an antitumor, antiangiogenic compound that has been shown to work by alkylating DNA, typically through addition of a methyl group to guanine in genomic DNA. The efficacy of this compound is dependent on its ability to methylate the DNA, thus triggering apoptosis; however, some cells are able to repair this damage via the enzymes O-6-methylguanine-DNA methyltransferase (MGMT). As a enzyme. Research has also been conducted to determine whether MGMT inhibitors such as O-6-benzylguanine might help to increase the efficacy of temozolomide. Furthermore, temozolomide has been implicated in causing arrest at the G2/M cell cycle checkpoint, which might also play a role in its cytotoxicity. |
