| Animal experiment : [2] | |
Animal models | Guinea Pigs |
Dosage form | Guinea Pigs were anesthetized with sodium pentobarbital (50 mg/kg i.p.). After 15 min of stabilization, SEA0400 were administered at doses of 1–10 mg/kg (each animal received only one dose) as i.v. bolus injection through the jugular vein. Five minutes later, 25 μg/kg of aconitine was injected to induce ventricular arrhythmias. |
Applications | SEA0400 showed no significant changes at dose of 10 mg/kg. The duration of normal sinus rhythm, PVC, narrow QRS VT and wide QRS VT were 21.5, 4.3, 17.3 and 16.8 min, respectively. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

SEA0400 is a potent and selective inhibitor of Na+-Ca2+ exchanger (NCX) with IC50 values of 5 to 33 nM in cultured neurons, microglia and astrocytes [1].The Na+-Ca2+ exchanger is an anti-porter that pumps Ca2+ out of the cells and keeps the low concentration of Ca2+ inside cells through exchanging the Na+ and Ca2+. In the reperfusion injury, the reverse mode NCX is activated, inducing the paradoxical Ca2+ influx and subsequently causing the generation of free radicals, leucotriene and thromboxane. Many existed drugs target NCX treated for reperfusion injury are reported of lacking selectivity or cell- permeability while SEA0400 is reported to be the most selective and potent NCX inhibitor [1]. SEA0400 was screened out of a chemical library designed for inhibition of NCX in cultured astrocytes and isolated cardiac sarcolemmal vesicles. It showed potent inhibitory effects on Na+-dependent Ca2+ uptake in cultured microglia, astrocytes and neurons with IC50 values of 8.3, 5 and 33 nM, respectively. The activity of SEA0400 was more than 100-fold higher than that of KB-R7943. SEA0400 was also proved to be selective against NCX over other ion fluxes since it displayed no significant effect on SOCE even at the concentration up to 3 μM. Besides that, SEA0400 had no effect on a serious of similar ion channels or ion transporters such as Ca2+-ATPase, Na+, K+-ATPase and K+ channel. Moreover, SEA0400 was found to suppress the Ca2+ influx-induced apoptosis in astrocytes [1].In a rat model of cerebral ischemia, injection of SEA0400 at dose of 3 mg/kg resulted in decreased infarct volume in both striatum and cerebral cortex. In a rabbit model of Langendorff-perfused 1-month myocardial infarction, SEA0400 administration inhibited the pacing-induced ventricular premature beats and displayed proarrhythmic activity through enhancing spatially discordant alternans (SDA) and steepening Action potential duration (APD) restitution [1 and 2].
