Abstract

In vitro studies suggested that the ammonium salt 2 could be a viable prodrug of the HIV-1 attachment inhibitor 1. Increased systemic exposure of the parent drug 1 following oral administration of the amminium salt 2 when compared to similar studies using solution dosing of the parent compound was observed in the in vivo studies in both rats and dogs. At high doses, the improvement in oral exposure of the parent drug was even more evident, indicating that the increased solubility of the amminium salt 2 can overcome dissolution-limited absorption and demonstrating the potential utility of this compound as a prodrug of 1.
