in vitro study | SB 239063 (0.1-10 μM ; 29 hours, 47 hours) increases apoptosis of eosinophils in a dose-related in the presence of 10 pM IL-5 at every time point from 21 hours onwards. SB 239063 potently inhibits IL-1 and TNF- a production in LPS-stimulated human peripheral blood monocytes with IC 50 values of 120 nM and 350 nM, respectively. Apoptosis Analysis Cell Line: Eosinophils Concentration: 0.1 μM, 1 μM, 10 μM Incubation Time: 29 hours, 47 hours Result: Increased apoptosis of eosinophils in a dose-related in the presence of 10 pM IL-5 at every time point from 21 hours onwards. |
Cell Line:
| Eosinophils (guinea pig BALs) |
Concentration:
| 0.1μM, 1μM, 10μM |
Incubation Time:
| 29 hours, 47 hours |
Result:
| Increased apoptosis of eosinophils in a dose-related in the presence of 10 pM IL-5 at every time point from 21 hours onwards. Significantly inhibited the resultant antigen-induced airport eosinophilia. |
in vivo study | SB 239063 (12 mg/kg; p.o.; 1 hour before and 4 hours after OA challenge; B. I. d. for 3 days) significantly inhibits the resultant antigen-induced airport eosinophilia. SB 239063 (12 mg/kg; P. o.) almost abolishes ovalbumin (OA)-induced airport eosinophilia (~ 93% inhibition) by inhalation. SB 239063 is a potent inhibitor of LPS-induced TNF-alpha production in the mouse peritoneal capacity with an EC 50 of 5.8 mg/kg (2.8-10.3; 95% CL). Animal Model: Male BALB/C MICE (18-20g) Dosage: 12 mg/kg Administration: Oral administration; 1 h before and 4 h after OA challenge; bis in die for 3 days result: Significantly inhibited the resultant antigen-induced airway eosinophilia. |
