Description

A liposomal formulation of benzoporphyrin derivative, monoacid ring A (BPD), a potent lipophilic photosensitizer, was evaluated in a mouse tumor model. DBA/2 mice, bearing the M1 (rhabdomyosarcoma) tumor were injected intravenously with 14C-BPD (at 4 mg/kg) formulated in either liposomal suspension (L-14C-BPD) or 6% DMSO-PBS solution (A-14C-BPD) and the tumor accumulation of 14C-BPD and biodistribution in mouse tissues were determined and compared. Efficiency of photodynamic treatment was determined in the M1 tumor model in DBA/2 mice following intravenous injection of BPD in either formulation (0.5-3 mg/kg) 3 h prior to laser light (690 nm) treatment (150 or 210 J/cm2). Distribution of L and A-14C-BPD in human blood and plasma was determined in vitro. (author). 11 refs., 5 figs., 2 tabs
