Description: T-2007, also known as DPB and 5,5-Diphenylbarbituric acid, is an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist and gamma-aminobutyric acid (GABA) receptor agonist potentially for the treatment of epilepsy. T2007 and its analogs upregulates CYP3A4 and MDR1. T-2007 depressed both the degree and the duration of posttetanic potentiation (PTP) in a dose-dependent manner.
