UCB1244283 is a synaptic vesicle glycoprotein 2A ( SV2A ) allosteric modulator. UCB1244283 binds to a secondary ligand-binding site in SV2A and enhances orthosteric ligand engagement when the orthosteric site is occupied, by stabilizing the occluded state and slowing ligand dissociation. UCB1244283 shows a clear protective effect against both tonic and clonic convulsions in sound-sensitive mice. UCB1244283 can be used for epilepsy research [1] [2] [3].
