Abstract

The C-26 modified monensin derivatives, 26-O-benzoylmonensin (3), 26-O-benzylmonensin (4) and 26-phenylaminomonensin (5) were prepared from monensin (1). Na+ ion transport activity through biological membrane and antibacterial activity of 3-5 were evaluated and compared with the activities reported for a 26-phenylurethane derivative (2). Among these compounds, 5 showed the largest Na+ ion transport and antibacterial activities. In these compounds, the formation of head-to-tail hydrogen bonds was suggested to be an important factor for Na+ ion transport and antibacterial activities.
