Cat. No. 1316
Biological ActivityA high affinity blocker for inward-rectifier K+ channels, this compound is a stable derivative of the bee venom toxin tertiapin. Binds to ROMK1 (Kir1.1) and GIRK1/4 (Kir3.1/3.4) channels with high affinity (Ki values are 1.3 and 13.3 nM respectively) and is selective over Kir2.1 channels. Derivative tertiapin LQ (Cat. No. 4339) also available.
