Abstract

Distribution coefficient (D) of rifabutin in liposome/water system was measured by phase separation and fluorescence probe quenching techniques. D values were identical suggesting that rifabutin is fully immersed into lipid bilayer. Structural studies of phospholipid bilayer employing ³¹P NMR spectroscopy demonstrated that introduction of rifabutin does not alter the bilayer structure. A scheme of the rifabutin position in lipid bilayer based on the calculated size of rifabutin molecule is proposed.
