Efonidipine(NZ-105)盐酸盐是T 型和L 型钙离子通道双重阻断剂。

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。

ω-Agatoxin IVA TFA 是一种高效的针对P Q型Ca2+(Cav2.1)通道的选择性阻滞剂，IC50对P型为2 nM，对Q型为90 nM。此化合物能够抑制高钾条件下的谷氨酸释放和钙流入，IC50在30-225 nM范围。同时，ω-Agatoxin IVA TFA阻断高钾诱发的5-羟色胺及去甲肾上腺素释放，但不影响L型或N型Ca2+通道。

ω-Conotoxin SO3为N型电压敏感钙通道的特异性阻断剂，源自C. striatus毒液，具备镇痛功能。

Huwentoxin I (HWTX-I)为一种肽毒素，针对电压门控钠通道和N型钙通道具有抑制作用。该化合物对大鼠海马神经元和蟑螂DUM神经元的钠离子通道展现出抑制能力，其IC50值分别为66.1 nM和4.80 nM。

ω-Conotoxin CVIB为非选择性N型及P Q型电压门控钙通道(VGCC)拮抗剂，能够抑制背根神经节(DRG)中神经元去极化后激活全细胞VGCC电流，其pIC50值为7.64。

N-Acyl taurines, such as N-lignoceroyl taurine, alongside various arachidonoyl amino acid conjugates like N-arachidonoyl dopamine and N-arachidonoyl-L-serine, have been identified in bovine brain and through mass spectrometry lipidomic studies in the brain and spinal cord of both wild-type and FAAH knockout mice. Notably, N-lignoceroyl taurine levels were found to be 23-26 times higher in FAAH knockout mice than in wild types, suggesting its degradation by FAAH, despite in vitro evidence showing FAAH hydrolyzes N-lignoceroyl taurine significantly slower than oleoyl ethanolamide. Additionally, N-acyl taurines with polyunsaturated acyl chains are known to activate TRPV1 and TRPV4 channels within the transient receptor potential (TRP) family of calcium channels.

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.

Ziconotide TEA acts by binding to N-type calcium channels situated on the terminal part of primary afferent neurons of the nociceptive pathway therefore reducing synaptic transmission with potent antinociceptive effects.

Peptide neurotoxin; selectively and reversibly blocks N-type calcium channels (IC50 = 0.15 nM). Reduces (RS)-3,5-DHPG -induced long term depression in vivo.

Peptide neurotoxin; wide spectrum blocker of N, P and Q type calcium channels.

Selective blocker of P-type calcium channels (IC50 < 1 - 3 nM). Also inhibits N-type channels at micromolar concentrations.
