Carabersat is a potent anticonvulsant agent.
[3H]Carabersat ([3H]SB 204269) binds to rat forebrain membranes with moderate affinity (Kd 40 nM) and pKi values of 7.3[1]. Carabersat is able to bind to mouse forebrain membranes, and the binding is saturable and stereospecific, with a Kd of 53 nM. The labelled [3H]Carabersat produces a Kd of 32 nM[2]. Carabersat (SB-204269, 1-100 μM) has no effect on Na+ current in cultured hippocampal neurones. Carabersat also shows no effect on action potential discharges evoked by elevating external K+[3]. Carabersat (SB-204269) is structurally-related to the benzopyran ATP-sensitive potassium channel (KATP) opener, cromakalim, but has opposite stereochemistry, and the mechanism of action of Carabersat is not thought to involve KATP[4].
Carabersat (5b) significantly elevates anticonvulsant activity in mice[1].
