TQ0307	Vernakalant RSD1235,维那卡兰	Potassium Channel	Membrane transporter/Ion channel
	Vernakalant (RSD-1235) is a mixed ion channel blocker.
T17227	Vernakalant Hydrochloride RSD1235 hydrochloride	Potassium Channel; Sodium Channel	Membrane transporter/Ion channel
	Vernakalant Hydrochloride (RSD1235 hydrochloride) 是一种混合电压和频率依赖性的 Na+ 和 K+ 通道阻断剂。Vernakalant 抑制 Kv1.5 channelwt，Kv1.5 channelI508F，Kv1.5 channelT479A，IC50 分别为 13.35±0.93 μM。
T39963	AP14145 hydrochloride
	AP14145 hydrochloride is a potent negative allosteric modulator of K Ca 2 (SK) channels, specifically targeting K Ca 2.2 (SK2) and K Ca 2.3 (SK3) channels with an IC 50 of 1.1 μM. Inhibition of AP14145 hydrochloride is highly influenced by S508 and A533 amino acids present in the channel. This compound effectively extends the atrial effective refractory period (AERP) in rats and exhibits antiarrhythmic properties in a Vernakalant-resistant porcine model of atrial fibrillation (AF).
T37821	AP 14145 hydrochloride
	KCa2 (small conductance Ca2+-activated potassium) channel negative allosteric modulator (IC50 = 1.1 μM). Increases the EC50 of Ca2+ on KCa2.3 channels by ~3-fold. Prolongs atrial effective refractory period (AERP) in rats. Reduces atrial fibrillation (AF) duration and prolongs atrial refractoriness without affecting ventricular refractory period in an animal AF model.
