• 説明

  Ethacrynic acid is a loop diuretic with anticancer activity., It inhibits the Na-K-2Cl (NKCC) cotransporter in duck erythrocytes (IC₅₀ = 0.18 mM) and ATP-dependent chloride uptake in rat renal plasma membrane vesicles when used at a concentration of 0.3 mM., Ethacrynic acid also inhibits glutathione S-transferase P1-1 (GSTP1-1) and GSTA3-3 (IC₅₀s = 4.9 and ~0.4 μM, respectively), and inhibits Wnt/β-catenin signaling in a cell-based reporter assay. It is cytotoxic to primary chronic lymphocytic leukemia cells (IC₅₀ = 8.56 μM), as well as MCF-7, MDA-MB-231, and 4T1 cancer cells (IC₅₀s = 45.53, 39.64, and 25.23 μM, respectively). Ethacrynic acid (250 μg per day) increases tumor growth reduction induced by the EGFR family inhibitors afatinib (Item Nos. 11492 | 21567) or neratinib in a 4T1 murine breast cancer model. Formulations containing ethacrynic acid have been used in the treatment of edema.

• 化学的特性

  White Solid

• 使用

  Ethacrynic acid is a powerful diuretic prescribed for edema associated with cardiac insufficiency, renal edema that does not respond to other diuretics, and edema of the brain and lungs.

• 定義

  ChEBI: An aromatic ether that is phenoxyacetic acid in which the phenyl ring is substituted by chlorines at positions 2 and 3, and by a 2-methylidenebutanoyl group at position 4. It is a loop diuretic used to treat high blood pressure resulting from diseases such as congestive heart failure, liver failure, and kidney failure. It is also a glutathione S-transferase (EC 2.5.1.18) inhibitor.

• 一般的な説明

  White solid.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  Ethacrynic acid may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents (such as alkali metals and hydrides) to release gaseous hydrogen. May react exothermically with acids. Reacts exothermically with all bases both organic (for example, the amines) and inorganic.

• 火災危険

  Ethacrynic acid is probably combustible.

• 作用機序

  The mechanism of action of ethacrynic acid appears to be more complex than the simple addition of sulfhydryl groups of the enzyme to the drug molecule. When the double bond of ethacrynic acid is reduced, the resultant compound is still active, although the diuretic activity is diminished. The sulfhydryl groups of the enzyme would not be expected to add to the drug molecule in the absence of the α,β-unsaturated ketone.
  These compounds are potent high-ceiling diuretics that resemble ethacrynic acid in their mechanism of action. The ethyl ester group represents a pro-drug that can be easily hydrolyzed to the free carboxyl group. As in ethacrynic acid, a 2,3-dichloro substitution is necessary. In addition, a para-hydroxyl group and an unsubstituted aminomethyl group on the benzene ring are highly beneficial. The carbonyl group can be replaced with an ether or sulfide group. These compounds have no ability to add the sulfhydryl groups of the kidney enzymes. The complete mechanism of action of these compounds remains in doubt.
