Description

Description générale

A cell-permeable, orally bioavailable, blood-brain barrier-permeant MTIC [5-(3-methyltriazen-1-yl-)-imidazole-4-carboxamide] prodrug whose in vivo DNA alkylating activity is employed in anticancer therapy. MGMT (O⁶-methylguanine DNA methyl transferase) repairs TMZ-damaged DNA lesion by covalently transferring O⁶-methylation on guanine residues to a cysteine residue on the MGMT, forming the basis of TMZ-resistance in cancer treatment.
