veratridine

Veratridine is a benzoate-cevane found in Veratrum and Schoenocaulon. It activates sodium channels to stay open longer than normal.

Veratridine (Standard) is a reference standard for research and analysis in studies involving Veratridine. Veratridine is a benzoate-cevane found in Veratrum and Schoenocaulon. It activates sodium channels to stay open longer than normal.

Nav1.7-IN-13 (compound 3g) is a sodium channel inhibitor that notably suppresses Veratridine-induced neuronal activity. It inhibits the total Na+ current in DRG neurons in a concentration-dependent manner and delays the activation of Navs. Nav1.7-IN-13 significantly alleviates mechanical pain behavior in a rat model of nerve injury (SNI), exhibiting analgesic properties.

Nav1.2-IN-2 (Compound 1) is an effective Nav1.2 inhibitor with an IC₅₀ of 0.18 μM for inactivated Nav1.2. Nav1.2-IN-2 suppresses the amplitude and frequency of spontaneous synchronized calcium oscillations (SCO) and inhibits Veratridine-induced calcium influx (IC₅₀ = 1.89 μM), making it suitable for epilepsy research.

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).
