Dacopafant (R-enantiomer RP 55778, racemate RP 48740) is an antagonist fo a platelet-activating factor and an inhibitor of TNH-alpha synthesis. It was developed by Rhone-Poulenc Rorer (France, now Aventis). In vitro, treatment of HIV-1 infected monocyte-derived macrophages with dacopafant resulted in a significant decrease in TNF-alpha levels and viral production. RP 48740 inhibited [3H]PAF platelet binding with IC50 of 2.3 uM and antagonized PAF-induced platelet activation with IC50 of 16 uM. In a clinical trial on human volunteers, RP 48740 was well tolerated and inhibited ex vivo platelet aggregation by as much as 79% 6 hr after administration.
