(Rac)-Modipafant (UK-74505) is an orally active, selective, long-acting irreversible platelet activating factor receptor (PAFR) antagonist. (Rac)-Modipafant prevents dengue infection[1][2][3].

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.
