Biochem/physiol Actions

Tenidap is an anti-inflammatory and anti-rheumatic with a variety of activities. Tenidap preferentially inhibits COX-1 with an IC50 value of 30 nM, and also has some lesser inhibitory activity towards COX-2 and 5-lipoxygenase (IC50 values are 1.2 and > 30 μM for COX-2 and 5-lipoxygenase respectively). Tenidap is also a cytokine modulator, an opener of inward rectifying hKIR2.3 channels (EC50 = 402 nM) and has been shown to modulate cytoplasmic pH and inhibit anion transport in vitro.
Tenidap is an anti-inflammatory, anti-rheumatic and cytokine modulator.
