Grayanotoxin I is a diterpene toxin that has been found in R. ponticum nectar, a component of mad honey. It increases resting sodium permeability in squid axonal membranes when used at a concentration of 10 µM. Grayanotoxin I (0.25, 0.5, and 1 mg/kg) induces proteinuria and reduces serum levels of alanine...

An active metabolite of propafenone, inhibits Ito in isolated human atrial myocytes (IC50 = 1.5 µM), increases the atrial effective refractory period in dogs at 0.5, 1, and 2 mg/kg. Formulation: A solid. InChI:...

Quinidine-d3 is intended for use as an internal standard for the quantification of quinidine (Cay-20356) by GC- or LC-MS. Quinidine is a stereoisomer of the antimalarial agent quinine (Cay-23958) and a class Ia antiarrhythmic agent. Quinidine blocks the voltage-gated sodium (Nav) channel Nav1.5 in a use-dependent...

Oxcarbazepine is a prodrug form of the antiepileptic compound 10,11-dihydro-10-hydroxy carbamazepine (Cay-18467). It inhibits high-frequency repetitive firing of rat spinal cord neurons when used at a concentration of 1 µM. Oxcarbazepine protects against electroshock-induced tonic hindlimb extension (ED50 = 10-20...

Zonisamide is a broad-spectrum sulfonamide antiepileptic agent. It selectively blocks the repeated firing of sodium channels (IC50 = 2 µg/ml) at low concentrations in mouse embryo spinal cord neurons, and it blocks spontaneous channel firing at concentrations above 10 µg/ml. In rat cerebral cortex neurons,...

Carbamazepine-d10 is intended for use as an internal standard for the quantification of carbamazepine by GC- or LC-MS. Carbamazepine is an anticonvulsant. It reduces the occurrence of seizures in mouse models of tonic-clonic, or maximal electroshock-induced, seizures (ED50s = 15.46 and ~13 mg/kg, respectively)....

Mexiletine is a voltage-gated sodium channel blocker and class Ib antiarrhythmic agent that preferentially binds to open/inactive channels. It inhibits aconitine-induced dysrhythmias in mice with ED50 values of 57 and 107 mg/kg for intraperitoneal and oral administration, respectively. Mexiletine decreases or...

10,11-dihydro-10-hydroxy Carbamazepine is an antiepileptic agent and active metabolite of the prodrug oxcarbazepine (Cay-17340). It is a racemic mixture of (R)- and (S)-10,11-dihydro-10-hydroxy carbamazepine. (S)-10,11-dihydro-10-hydroxy Carbamazepine protects against seizures induced by maximal electroshock (MES)...

Lennox-Gastaut syndrome (LGS) is a severe pediatric epilepsy syndrome characterized by multiple seizure types. Rufinamide is an anticonvulsant. It inhibits the activation of voltage-gated sodium channel 1.1 (Nav1.1) when used at a concentration of 100 µM. Rufinamide inhibits Nav1.1, but not Nav1.2, Nav1.3, and...

Fosphenytoin is a prodrug of phenytoin that is rapidly converted to phenytoin, a voltage-gated sodium channel blocker, in vivo. It induces less tissue damage compared with two other phenytoin prodrugs in rats following subcutaneous and intramuscular administration. Fosphenytoin has anticonvulsant activity in a mouse...

Eslicarbazepine is a voltage-gated sodium channel (Nav) inhibitor and an active metabolite of the prodrug eslicarbazepine acetate (Cay-23656). It enhances slow activation of voltage-gated sodium channels, reducing channel availability. Eslicarbazepine is protective against seizures induced by maximal electroshock...

Description: Disopyramide (Triombrin) is a class I anti-arrhythmic agent (one that interferes directly with the depolarization of the cardiac membrane and thus serves as a membrane-stabilizing agent) with a depressant action on the heart similar to that of guanidine. It also possesses some anticholinergic and local...
