COX

Cyclooxygenase

Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme that is responsible for formation of important biological mediators called prostanoids, including prostaglandins, prostacyclin and thromboxane. Pharmacological inhibition of COX can provide relief from the symptoms of inflammation and pain. Drugs, like Aspirin, that inhibit cyclooxygenase activity have been available to the public for about 100 years. Two cyclooxygenase isoforms have been identified and are referred to as COX-1 and COX-2. Under many circumstances the COX-1 enzyme is produced constitutively (i.e., gastric mucosa) whereas COX-2 is inducible (i.e., sites of inflammation). Non-steroidal anti-inflammatory drugs (NSAID), such as aspirin and ibuprofen, exert their effects through inhibition of COX. The main COX inhibitors are the non-steroidal anti-inflammatory drugs (NSAIDs).

    Flufenamic acid-13C6
    Inhibitor
    Flufenamic acid-13C6 is the 13C6 labeled Flufenamic acid. Flufenamic acid is a non-steroidal anti-inflammatory agent, inhibits cyclooxygenase (COX), activates AMPK, and also modulates ion channels, blocking chloride channels and L-type Ca2+ channels, modulating non-selective cation channels (NSC), activating K+ channels. Flufenamic acid binds to the central pocket of TEAD2 YBD and inhibits both TEAD function and TEAD-YAP-dependent processes, such as cell migration and proliferation.

    APHS
    Inhibitor 99.0%
    APHS is a specific and covalent COX-2 inhibitor with neuroprotective effects. COX-2 is a prostaglandin (PG) synthetase overexpressed in colorectal cancer (CRC) and has pleiotropic cancer-promoting effects. APHS modifies COX-2 by acetylating the active site (serine 516), thereby inhibiting prostaglandin production. The neuroprotective activity of APHS is inhibited by prostaglandin E2. APHS also co-inhibits the WNT pathway, an anti-tumor mechanism in addition to COX-2 inhibition.
