WebOct 19, 2024 · A Blocker of Kir1.1, Kir3.1 and Kir3.4 K+ Channels WebTertiapin-Q is a stable derivative of the bee venom toxin tertiapin. Tertiapin-Q binds to ROMK1 (K ir 1.1) and GIRK1/4 (K ir 3.1/3.4) channels with high affinity (K values are 1.3 and 13.3 nM respectively) and is selective over K ir 2.1 channels. Tertiapin-Q improves heart rate and atrioventricular conduction in a mouse model of bradycardia.
