Biological Activity
| Targets | mGluR 1 |
| ln Vitro | For rat mGluR1-NIH membranes, YM-298198 hydrochloride exhibits a strong affinity for mGluR1 with a Ki of 19 nM[1]. With an IC50 of 16 nM, YM-298198 hydrochloride suppresses glutamate-induced inositol phosphate synthesis in mGluR1-NIH3T3 cells[1]. When applied to mGluR2, 3, 4a, 6, or 7b, YM-298198 hydrochloride exhibits neither agonistic nor antagonistic activity up to 10 μM[1]. |
| ln Vivo | Mice with streptozotocin-induced hyperalgesia exhibit a notable analgesic response when given YM-298198 hydrochloride (30 mg/kg; po)[1]. |
| Animal Protocol |
Animal/Disease Models: Male ICR mice[1] Doses: 30 mg/kg Route of Administration: Oral administration Experimental Results: Prolonged nociceptive response latency in streptozotocin (200 mg/kg)-induced hyperalgesic mice. |

Solubility Data
| Solubility (In Vitro) | DMSO: 125 mg/mL (329.88 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.49 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 20.8 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: ≥ 2.08 mg/mL (5.49 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 20.8 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.  (Please use freshly prepared in vivo formulations for optimal results.) |
