Description | Vernakalant Hydrochloride (RSD1235 hydrochloride) is a mixed voltage- and frequency-dependent Na+ and atria-preferred K+ channel blocker. |
Targets&IC50 | Kv1.5 channel (T479A):1.63±0.09 μM, I508F:0.61±0.03 μM, Kv1.5 channel (WT):13.35±0.93 μM |
In vitro | Block of Kv1.5 by Vernakalant Hydrochloride occurs after channel activation, as Vernakalant induces a rapid block of channel current upon depolarization with minimal resting or “tonic” block. The most significant effect is the reduction in potency at I502A, with an IC50 of 329±19 μM (n=4-10) compared to a control IC50 of 13.4±0.9 μM (n=5-23), reflecting a 25-fold potency decrease. Lesser reductions in potency, between 3- and 4-fold, were noted for V505A, I508A, T480A, and C500A. For wild-type and mutant Kv1.5 channels, IC50 for Vernakalant block are 13.35±0.93 μM, 0.61±0.03 μM, and 1.63±0.09 μM for Kv1.5 channels, Kv1.5 channelI508F, and Kv1.5 channelT479A, respectively [1]. |
