Liposomal and free rifabutin were separated by the method of gel filtration. The percents of rifabutin bound to liposomes of different phospholipid composition were measured. The presence of negatively charged phospholipids increased the degree of binding. Binding decreased with increasing the ionic strength. Incubation of rifabutin with liposomes containing anthryl phosphatidylcholine was accompanied by fluorescence quenching. Activity of rifabutin depended on the phospholipid composition of liposomes. Our results indicate that binding of rifabutin is associated with electrostatic and hydrophobic interactions.

UI MeSH Term Description Entries
D007477 Ions An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.

D000327 Adsorption The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily. Adsorptions
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
