sFTX-3.3 is a calcium ion channel antagonist, exhibiting IC50 values of approximately 0.24 mM and 0.70 mM against P-type and N-type channels respectively.
Azelnidipine, (S)-, is an L-type calcium channel blocker (CCB). Studies have shown that in patients with hypertension (HT) and heart failure preserved ejection fraction (HFpEF), azelnidipine improved the severity of HF and cardiac sympathetic nerve activity compared with cilnidipine, an N-type CCB (Cat#326734).
Azelnidipine, (R)-, is an L-type calcium channel blocker (CCB). Studies have shown that in patients with hypertension (HT) and heart failure preserved ejection fraction (HFpEF), azelnidipine improved the severity of HF and cardiac sympathetic nerve activity compared with cilnidipine, an N-type CCB (Cat#326734).
Huwentoxin XVI TFA,一种来自鸟蛛 Ornithoctonus huwena 的止痛剂,一种高度可逆和选择性的哺乳动物 N 型钙通道 (N-type calcium channel) (IC50约为 60 nM) 拮抗剂。Huwentoxin XVI TFA 对电压门控的 T 型钙通道,钾通道或钠通道没有影响。
ML-252 is a potent, selective inhibitor of the Kv7.2 voltage-gated potassium channel, demonstrating an IC50 value of 69 nM in patch clamp assays. It exists as the (S)-enantiomer, which is significantly more effective than both its (R)-enantiomer counterpart and the racemic mixture, with respective IC50 values of 944 nM and 160 nM. ML-252 exhibits high selectivity for Kv7.2 over other potassium channel subtypes and shows minimal activity against more than 68 G protein-coupled receptors, various transporters, L- and N-type calcium channels, K_ATP, and hERG potassium channels. However, it does inhibit the melatonin MT1 receptor by 61% at a 10 µM concentration.
