This was further confirmed by the fact that LF 1695 inhibited the second wave of platelet aggregation induced by ADP as well as arachidonic acid effects. Incubation of platelets with [14C]arachidonic acid in the presence of 60 microM LF 1695 resulted in a strong inhibition of arachidonic acid incorporation into the various cell lipids, indicating that arachidonic acid mobilization might be due to inhibition of reacylation processes._x000D_

in vivo
CBA, H2k mice receiving a lethal dose of irradiation were injected with spleen cells from LF 1695-treated or untreated C57 Bl/6, H2b mice via different routes. Mice treated intraperitoneally with LF 1695 at 2.5 or 5 mg/kg/day showed an increase of GvHR intensity with splenic index of 1.71 and 1.80, respectively. When the animals were treated continuously through drinking water containing LF 1695 (4 mg/kg, 10 mg/kg or 100 mg/kg), these ratios were: 1.82, 1.10 and 1.37, respectively. Finally, LF 1695 enhanced GvHR significantly when used at low doses, while high doses induced a decrease of GvHR intensity._x000D_
