|Description||Acemetacin is a non-steroidal anti-inflammatory drug and a glycolic acid ester of indometacin that is a cyclooxygenase inhibitor.|
Acemetacin is less potent than indomethacin in causing a concentration-related inhibition of PGE accumulation in gastric mucosal incubates. Acemetacin is also less potent than indomethacin in reducing gastric 6-keto-PGF1 alpha and TXB2.  Acemetacin probably exerts actions independent of conversion to Indomethacin, given the different effects of these two drugs on LTB(4) production.  Acemetacin is a prodrug of indomethacin that exhibits better gastric tolerability in preclinical and clinical trials. Acemetacin involves the sequential participation of nitric oxide (NO) or K+ channel pathways to confer its antinociceptive effect.  Acemetacin exhibits the anti-inflammatory effect through PG synthesis inhibition. Acemetacin prevents the PGE2 release only at the high concentration of 10 μM in inflamed synovial tissue. Acemetacin exhibits less potent inhibitory effect on PGE2 release from the synovial membrane in the in vitro study. 
|In vivo||Acemetacin induces significantly less gastric and intestinal damage than indomethacin in rats pretreated with inhibitors of COX-2 and NOS, despite markedly suppressing COX activity. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
