Bioactivity | KRM-II-81 is a gamma-aminobutyric acid type A (GABAA) receptor ligand with analgesic, anxiolytic and anti-epileptic activities. KRM-II-81 exhibits positive allosteric modulation of GABAA receptors selective for the α2/3 subunit. KRM-II-81 reduces formalin-induced pain response after oral administration. KRM-II-81 significantly reduces pain behavior induced by chronic spinal nerve ligation. Analysis of KRM-II-81 showed that its plasma and brain concentrations were positively correlated with analgesic effects. The enhancement effect of KRM-II-81 on GABA current shows its key role in the analgesic mechanism. KRM-II-81 was less effective in respiratory depression, demonstrating its safety and tolerability[1]. |
