Temobela medicine is made in the form of capsules, with the main ingredient being Temozolomide 5mg. Temozolomide is a derivative of imidazotetrazin. At physiological pH, pharmacologically inactive Temozolomide is hydrolyzed to the active Monomethyl triazeno imidazol carboxamine (MTIC). MTIC acts on multiple phases of the cell cycle, causing cytotoxicity by alkylation at the O6 and N7 positions of guanine in DNA. The subsequent progressive cytotoxic injury is also thought to be related to the aberrant repair of methyl radicals.
