U(DDC) synthesis inside the liposomes. Nigericin facilitates the exchange of K ions in exchange for H. Thus, CuSOliposomes have been exchanged into a KClHistidinecontaining buffer (see Solutions) and subsequently nigericin was added. 
As noted in Figure C, the formation of Cu(DDC) inside the DSPCChol liposomes was not impacted by the change in external buffer or the addition of nigericin. Following iv administration into mice, the plasma copper levels min immediately after administration have been comparable for the nigericin formulation and the formulation prepared without the need of nigericin (Figure D). This suggests that a rise in pH within the liposomes has no effect on the stability of your CFI-400945 (free base) injected formulation. To assess how liposomal lipid composition influences the in vivo elimination of intravenously injected Cu(DDC), we evaluated Cu(DDC) formulations prepared in,) Cholcontaining liposomes DSPCChol (:) and SMChol (:),) Cholfree liposomes (DSPCDSPEPEG (:) and SMDSPEPEG (:)), at the same time as) charged liposomes anionic (DSPCDSPGChol (::) and cationic (DSPCDSPGChol (::)). These studies (summarized in Figure) employed plasma Cu(DDC) levels determined min following iv administration as a measure of whether alterations in lipid composition could engender decreases in Cu(DDC) elimination. Even though not shown, the ability to synthesize Cu(DDC) inside the different liposomal formulations was not affected by liposomal lipid composition.
