STUDIES ON CHEMICAL MODIFICATION OF MONENSIN .6. PREPARATION OF C-7 MODIFIED MONENSINS VIA PROTECTED 7-OXOMONENSIN AND EVALUATION OF THEIR ION-TRANSPORT ACTIVITY
A. Nagatsu et al., STUDIES ON CHEMICAL MODIFICATION OF MONENSIN .6. PREPARATION OF C-7 MODIFIED MONENSINS VIA PROTECTED 7-OXOMONENSIN AND EVALUATION OF THEIR ION-TRANSPORT ACTIVITY, Chemical and Pharmaceutical Bulletin, 45(6), 1997, pp. 966-970
7-Carboxymethylmonensin (3), 7-aminomonensin (4), and 7-oxomonensin (5
) were synthesized via protected 7-oxomonensin (2), which is expected
to be a useful intermediate for the preparation of various monensin de
rivatives. Compounds 3-5 exhibited smaller ion transport activity than
monensin (1).
