Isoxsuprine  (Synonyms: 异克舒令；异舒普林)

MCF-7^ALOX12 cells are seeded in 3.5-cm dishes and grown in 2.5 mL complete MEM medium without selection pressure. The next day, the medium is changed to serum-free medium and cells are kept at 37 °C for 24 h. Then, cells are treated with 10 μM arachidonic acid and simultaneously with different concentrations of Isoxsuprine for 4 h when the supernatants are aspirated, centrifuged at 2000, r.p.m. at 4 °C for 5 min, collected in cryo-tubes, flash frozen and stored at -80 °C until analysis^[2].

Male spontaneously hypertensive rats (SHR) weighing 290 to 300 g are used in this study. At reperfusion, animals receive 0.5 mL of vehicle (0.6% DMSO in normal saline) or 1 mg/kg Isoxsuprine by intravenous (IV) injection through the lateral tail vein. All animals receive 3 mL of subcutaneous saline after surgery to prevent dehydration. After 24 hours reperfusion, animals are sacrificed, brains are sectioned into 4 mm-thick quadrants, and infarcted tissue is identified by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Edema-corrected infarct volume is calculated by subtracting the area of non-infarcted tissue in the ipsilateral hemisphere from the total volume of the contralateral hemisphere. Infarct volume is quantified using Image J software^[3].
