[In Vivo]
(Rac)-Modipafant (UK-74505) (10 mg/kg; p.o.; twice a day until day 10) prevents Severe Dengue Infection[3]. (Rac)-Modipafant exhibits highly selective, time-dependent inhibition of PAF-induced aggregation of rabbit washed platelets (IC50=26.3 and 1.12 nM after 0.25 and 60 min preincubation, respectively)[4]. (Rac)-Modipafant (5-20 mg/kg; p.o.) dose-dependently inhibits the Zymosan -induced articular hyperalgesia[5]. Animal Model: 8- to 10-week-old BALB/c mice (DEN-2 strain infected)[3] Dosage: 10 mg/kg Administration: P.o.; twice a day (started on days 0, 3, 5, or 7) until day 10 Result: Decreased by approximately 50% the lethality associated with DEN-2 infection. Animal Model: Male BALB/C (8- to 10- week-old) wild-type mice[5] Dosage: 5, 10 and 20 mg/kg Administration: P.o. Result: Dose-dependently inhibited the Zymosan -induced articular hyperalgesia.
