In vivo study | Mean animal survivals of the ONO4057-treated animals significantly prolong to 21.0±4.4 days compare with 12.0±0.6 days in control group. Histological findings from grafts taken on day 7 show that severe focal cellular infiltration is observed in both groups, but the degree of hepatocyte necrosis in ONO4057-treated anmimals is milder than that in control group. |
biological activity | ONO4057 is an antagonist of the leucotriene B4 receptor with an IC50 value of 0.7±0.3 μm. |
