Biological Activity
Zonampanel inhibits the human MRP4-mediated transport of [3H]oestradiol 17-D-glucuronide in a concentration-dependent manner. In contrast, Zonampanel (up to 1000 mM) does not inhibit the human MRP2- or BCRP-mediated transport of [3H]oestradiol 17-D-glucuronide or [3H]methotrexate[1]. Zonampanel inhibits the uptake of typical substrates by Oat1, Oat2, and Oat3 with inhibition constant (Ki) values of 7.02 to 10.4 μM. A time- and saturable concentration-dependent increase in [14C]Zonampanel uptake is observed in these cells [Km values: 13.4 to 53.6 μM][2].

* In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light)
Solvent & Solubility
DMSO : 50 mg/mL (150.95 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.55 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (7.55 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Seven-week-old male Sprague-Dawley rats are used at 8 weeks after acclimatization for at least 1 week. During acclimatization, the rats are kept in an air-conditioned room with temperature and humidity controlled at 22.9 to 23.3°C and 50 to 78%; the room is lit for 12 h 30 min from 7:30 AM to 8:00 PM. Rats are given free access to solid food and water until just before drug administration. YM 872 (15 mg/kg) is administered at a single bolus dose into the rat tail vein with or without probenecid (50 mg/kg) or cimetidine (40 mg/kg). At 5, 15, and 30 min and 1, 2, 3, 4, and 6 h after dosing, blood is sampled under ether anesthesia via the inferior vena cava using a heparinized syringe and immediately stored on ice using four rats each per sampling time point per administration group (total of 128 rats for 8 sampling time points and 4 administration groups). Plasma is obtained by centrifugation at 4°C, 1870 g for 15 min and kept frozen at -20°C. Rats for plasma sampling at 3 and 6 h after administration are housed in metabolic cages after administration, spontaneously excreted urine is collected, and the cages are washed using water. Regarding specific gravity as 1, urine volume (including the cage-wash water) is calculated according to differences in the weight of the sampling tube before and after sampling. Urine samples are kept frozen at -20°C until assay as described below. All plasma and urine samples are protected from light throughout the sampling, storage, and assay procedures.
