K134 (K-134) inhibits rat platelet aggregation induced by collagen and ADP in a dose-dependent manner in vitro. The half-maximal (50%) inhibitory concentration (IC50) values of K134 are 2.5 µM and 3.2 µM, respectively. In vitro experiments, K134 also inhibits mouse platelet aggregation induced by collagen and ADP in a dose-dependent manner, and the IC50s are 5.5 µM and 6.7 µM, respectively[1].

Solvent & Solubility
DMSO : 50 mg/mL (125.16 mM; Need ultrasonic; 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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.26 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 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
Mice[1]
Male ICR mice, 5-8 weeks old, are used. K134 (K-134) and Warfarin are suspended and dissolved in 1% HPMC, respectively, and orally administered to ICR mice at 10 min or 24 h before testing of bleeding, respectively. Each mouse is placed in a restrainer, which exposes the tail. A 27G disposable needle is inserted about 6 mm into a tail vein 2 cm from the tip of the tail. Immediately after the operation, sheets of filter paper are placed under the injury site every 15 sec to absorb the blood, and the time point at which no blood is observed on the filter paper is regarded as the bleeding time.
