tetracaine

Tetracaine hydrochloride (Amethocalne HCl) 是一种钙通道蛋白抑制剂，可阻断肌浆网中 Ca2+的电压敏感释放。它主要用作眼科的止痒剂和局部用药，可用于表面和脊髓麻醉。

Tetracaine-d6 是 Tetracaine 的氘代化合物。Tetracaine 的 CAS 号为 94-24-6。

Benzonatate 是外周口服镇咳药，对咳嗽延伸受体 (cough stretch receptors) 的活性具有抑制作用。它是丁卡因样代谢物，能够阻断呼吸延伸受体的钠通道并产生局部麻醉作用。

PD-85639 is a voltage-gated sodium (Na+) channel blocker (75% in 10 min & >95% in 25 min blockage of Na+ current by 25 μM PD85,639; whole-cell patch clamp using primary rat brain neurons) that is shown to target rat brain Nav1.2 with simultaneous high- and low-affinity modes of binding (EC50 = 56 nM 40% & 20 μM 60% at pH 9.0, 5 nM 28% & 3 μM 72% at pH 7.4, against 2 nM [3H]-PD85,639 for binding rat brain synaptosomes; EC50 = 17 nM 39% & 10 μM 61% using at pH 9.0 using rat brain synaptosome membranes) and a fast kinetic (t1 2 = 1.2 at 4°C, <0.5 min at 25°C), competitive against the local anesthetic Na+ channel blockers tetracaine, bupivacaine, and mepivacaine, as well as Na+ channel activators veratridine and batrachotoxin (K1 = 0.26 μM against 5 nM [3H]-BTX for binding rat neocrotical membranes).

ent-(+)-verticilide is an effective and specific inhibitor of cardiac ryanodine receptor (RyR2) calcium release channels, demonstrating antiarrhythmic properties. It suppresses RyR2-mediated diastolic Ca2+ leak and shows greater potency and a unique action mechanism compared to Dantrolene and Tetracaine. ent-(+)-verticilide serves as a valuable tool for exploring the therapeutic potential of addressing RyR2 hyperactivity in cardiac and neurological conditions [1].
