Description

General description

Temozolomide is a small lipophilic alkylating agent. It interacts covalently with the nucleophile microenvironment within DNA (Guanine residues). Due to this property temozolomide is considered a cytotoxic agent. The mechanism of action of TMZ is dependent upon its ability to hydrolyze DNA, resulting in DNA degradation and destruction of tumor cells. Malignant Glioma cells respond primarily to TMZ by G2/ M cell cycle arrest or in rare cases by apoptosis. 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.

Application

Temozolomide has been used for analyzing drug resistance mechanisms in glioblastoma cell lines. Temozolomide has been used to induce cytotoxic effects on glioblastoma cells to study the outcome of protein disulfide isomerase (PDI) inhibition.
