Biochem/physiol Actions

Temozolomide is a DNA methylating agent and drug resistance-modifying agent; anti-tumor and anti-angiogenic. Temozolomide induces G2/M arrest and apoptosis through adduction of a methyl group to O6 position of guanine in genomic DNA and functional inactivation of DNA repair protein O(6)-alkylguanine DNA alkyltransferase (AGT) in base excision repair (BER) pathway.
