sk channel

SK3 Channel-IN-1 (compound 7a) is a powerful and selective modulator of the SK3 channel. It demonstrates significant efficacy in inhibiting breast cancer MDA-MB-435 cell migration while maintaining low cytotoxicity in other cell lines. Furthermore, SK3 Channel-IN-1 exhibits the ability to modulate ion channel activity in cancer cells [1].

Rimtuzalcap (CAD-1883) 是首创的，选择性的小电导钙激活钾通道 (SK 通道) 正变构调节剂。Rimtuzalcap 可用于运动障碍的研究，包括脊髓小脑性共济失调 (SCA)和特发性震颤 (ET)。

ICA (N-[4-(2-Pyridinyl)-2-thiazolyl]-2-pyridinamine) 是有效的 SK 通道抑制剂。ICA 显示出抗利什曼原虫的活性，IC50为2.1 µM。

UCL-1848 trifluoroacetate salt is a selective Ca2+-activated, SK potassium channel blocker.

Bupivacaine is a BK/SK, Kv1, Kv3, TASK-2 K Channel and voltage-gated Na channel blocker used as an anesthetic. It maybe neurotoxic at high does, inducing apoptosis in neuroblastoma cells. It acts by binding to the intracellular portion of voltage-gated sodium channels and blocking sodium influx into nerve cells.

Tamapin TFA为靶向小电导Ca(2+)激活的K(+) (SK)通道的毒液肽，特异性抑制SK2（钾通道）并阻断海马锥体神经元中SK通道介导的电流。该化合物可从印度红蝎(Mesobuthus tamulus)毒液中提取。

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).

Tamapin为靶向小电导Ca(2+)激活的K(+) (SK)通道的毒液肽，尤以钾通道SK2为选择性阻断剂。该化合物能够抑制海马锥体神经元SK通道介导的电流，来源于印度红蝎(Mesobuthus tamulus)。

Bisoprolol hemifumarate 是一种 β1 肾上腺素受体阻断剂。
