Temocapril Metabolism Pathway

Homo sapiens
Temocapril (trade name: Acecol) belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors and is used primarily to lower high blood pressure (hypertension). This drug can also be used in the treatment of congestive heart failure and type II diabetes. Temocapril is a prodrug which, following oral administration, undergoes biotransformation in vivo into its active form temocaprilat via cleavage of its ester group by the liver. Angiotensin-converting enzyme (ACE) is a component of the body's renin–angiotensin–aldosterone system (RAAS) and cleaves inactive angiotensin I into the active vasoconstrictor angiotensin II. ACE (or kininase II) also degrades the potent vasodilator bradykinin. Consequently, ACE inhibitors decrease angiotensin II concentrations and increase bradykinin concentrations resulting in blood vessel dilation and thereby lowering blood pressure.

Temozolomide Action Pathway

Homo sapiens
Temozolomide (TMZ) is an antineoplastic from the alkylating agent drug class. This molecule is an imidazotetrazine prodrug that is stable at acidic pH but undergoes spontaneous nonenzymatic hydrolysis at neutral or slightly basic pH; allowing its administration to be oral and intravenous too. Temozolomide is indicated in the treatment of newly diagnosed glioblastoma and refractory anaplastic astrocytoma. This molecule is a very small lipophilic, it can then easily get through the blood-brain barrier. The mechanism of action of this drug needs many reactions beforehand: TMZ undergoes spontaneous nonenzymatic breakdown at physiological pH to form 5-(3-methyltriazen-1-yl) imidazole-4-carboxamide (MTIC), which then reacts with water to produce 5-aminoimidazole-4-carboxamide (AIC) and a highly reactive methyl diazonium cation. TMZ is a bit specific to tumor cells because glioblastoma typically possesses a more alkaline pH than healthy tissue, favoring its activation in tumor cells. The methyl diazonium cation formed methylates DNA at the N7 and O6 position of guanine, and the N3 position of adenine. The cellular repair system will eventually lead to DNA strand breaks that will end in the apoptosis of the cell.
