Biological Activity
| Targets | Kb: 1.4 nM (GluK1)[1] |
| ln Vitro | At all tested concentrations (up to 100 μM), UBP316 is ineffective at GluK2 (GluR6) receptors, while at 1 μM, it had no effect at GluK3 (GluR7) receptors[1]. Following repeated spikes, UBP316 (200 nM) lessens the pre-synaptic calcium transients' short-term facilitation[1]. In vitro, UBP316 successfully counteracts GluK1-mediated suppression of excitatory transmission in the hippocampal CA1 region[1]. Long-term potentiation (LTP) that is not dependent on NMDA receptors is inhibited by UBP316[1]. |

Solubility Data
| Solubility (In Vitro) |
1M NaOH: 80 mg/mL (186.28 mM) DMSO: 2 mg/mL (4.66 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.2 mg/mL (0.47 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 2.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 0.2 mg/mL (0.47 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 2.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 0.2 mg/mL (0.47 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 2.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
