Meclofenamic acid-d4 is the deuterium labeled Meclofenamic acid. Meclofenamic Acid (Meclofenamate), a non-steroidal, anti-inflammatory agent, is a highly selective fat mass and obesity-associated (FTO) 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[1][2][3].
