Meclofenamic acid
Based on 9 publication(s) in Google Scholar
Meclofenamic acid (Meclofenamate) is a non-steroidal anti-inflammatory agent. Meclofenamic acid is a highly selective FTO (fat mass and obesity-associated) enzyme inhibitor. Meclofenamic acid competes with FTO binding for the m(6)A-containing nucleic acid. Meclofenamic acid is a non-selective gap-junction blocker. Meclofenamic acid inhibits hKv2.1 and hKv1.1, with IC50 values of 56.0 and 155.9 μM, respectively.

Meclofenamic acid (0-100 μM, 24 h) inhibits FTO demethylation in a dose-response manner[1].
Meclofenamic acid inhibits enzyme cyclooxygenase, with an IC50 about 1 μM, thereby inhibiting the production of prostaglandins[2].
Meclofenamic acid inhibits the release of 5-HETE and LTB4 from human neutrophils stimulated with calcium ionophore and antagonizes the response of tissues to certain prostaglandins[2].

Meclofenamic acid purchased from MedChemExpress. Usage Cited in: Theranostics. 2021 Jul 25;11(17):8464-8479. [Abstract]
The effect of FTO inhibitor Meclofenamate sodium (MS) (80 μM and 120 μM) on ATF4 protein expression and mTORC1 activity during 968 treatment is detected by western blotting. MS efficiently reduces ATF4 expression and rescues the mTOR downregulation induced by compound 968.
