[A synthesis and properties of new 4,4-difluoro-3a,4a-diaza-s-indacene (BODIPY))-labeled lipids].

A series of fluorescently labeled fatty acids of various chain lengths with 4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene-8-yl (Me4-BODIPY-8) residue in the omega-position were synthesized. These acids were used to prepare new fluorescently labeled phosphatidylcholines, sphingomyelin, and galactosyl ceramide. Taking into account the symmetry of the Me4-BODIPY-8-fluorophore, one can presume that, in most bilayer membrane systems, this fluorophore is would be embedded into the bilayer.
