Biological Activity

Description Acemetacin (K-708,TVX 1322) is a non-steroidal anti-inflammatory drug and a glycolic acid ester of indometacin that is a cyclooxygenase inhibitor.
Targets
COX [1]
In vitro

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. [1] Acemetacin probably exerts actions independent of conversion to Indomethacin, given the different effects of these two drugs on LTB(4) production. [2] 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. [3] 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. [4]

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. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
