Metyrapone Tartrate  (Synonyms: Su-4885 Tartrate)

Metyrapone (Su-4885) Tartrate is a potent and orally active 11β-hydroxylase inhibitor and an autophagy activator, also inhibits the production of aldosterone. Metyrapone Tartrate inhibits synthesis of endogenous adrenal corticosteroid, decreases glucocorticoid levels, and also affects behavior and emotion. In addition, Metyrapone Tartrate increases the efficiency of autophagic process via downregulation of mTOR pathway, and interacts with Pseudomonas putida cytochrome P-450. Metyrapone Tartrate can be used for researching Cushing's syndrome and depression^{[1][2][3][4][5]}.

11β-hydroxylase, Aldosterone, CYP450, Autophagy^[1][4][5]

Metyrapone (100 μM; 2 h) hyperactivates autophagy in HepG2, and delays the activation of apoptosis at severe endoplasmic reticulum (ER) stress^[5].

Metyrapone (25 or 50 mg/kg; SC, single dosage) decreases the stress-induced increase in plasma corticosterone levels, significantly impairs acquisition performance at high dosage, and increases open arm activity at low dosage^[1].
