Biologische Aktivität
Pemirolast (1 μM-1 mM) inhibits A23187-induced LTC4 and ECP release from the eosinophils in a dose-dependent manner[1].
Pemirolast (0.1-1 mM) also inhibits PAF-induced and FMLP-induced ECP release from the eosinophils[1].
Pemirolast prevents the activation of human eosinophils to inhibit granule protein LTQ and ECP release, so that alleviates controlling allergic diseases[1].
Pemirolast (100 nM-1 mM; 1-15 min) fails to significantly inhibit histamine release from human conjunctival mast cells[2].
Pemirolast (0.1 μg/mL-0.01 mg/mL) inhibits the activation of signal transduction phospholipases C and AZ in rat peritoneal mast cells, by inhibiting the degranulation reaction of antigen and compound 48/80, suppressing the formation of 1,2-diacylglycerol and phosphatidylic acid[3].

Pemirolast (0.1-1 mg/kg; i.v.) inhibits taxel-induced pulmonary vascular hyperpermeability, and reverses paclitaxel-induced arterial PaO2 decreasing at a dosage of 1 mg/kg, 30 minutes after paclitaxel (HY-B0015) injection (15 mg/kg; i.v.)[4].
Pemirolast (10 mg/kg/d; p.o.; 4-5 d) significantly reduces Cisplatin (HY-17394)-induced kaolin intake on days 3 and 4 and inhibits cisplatin-induced substance P release in the cerebrospinal fluid (CSF) in rats[5].

Animal Model:Male Wistar rats (6-week-old, 160-250 g)[5]
-
Dosage:10 mg/kg
-
Administration:Oral gavage; 5 days: 1 h or 30 min before and 24, 48, 72 and 96 h (five times in total) after administration of cisplatin (2-10 mg/kg; i.v.)
-
Result:Inhibited the cisplatin-induced increase in kaolin intake on days 3 and 4, without decreasing in normal feed intake.
