| Bioactivity | UMB68 sodium is a selective GHB receptor ligand. UMB68 sodium displaces [3H]NCS-382 with an IC50 of 38 nM in rat cerebrocortical membranes. UMB68 sodium has no significant affinity at GABAB receptors, cannot be metabolized to GABA-active compounds[1]. |
| Target | GHB receptor |
| Invitro | UMB68 inhibits [3H]NCS382 (16 nM) binding to the rat cerebrocortical membranes, with an IC50 of 38 nM compared with 25 μM for GHB[1].UMB68 shows no affinity (IC50 >100 μM) at GABA(A) or GABA(B) receptors[1]. |
| In Vivo | UMB68 (320-1778 mg/kg; i.p.) decreases markedly lever pressing in rats[1]. Animal Model: |
