The synthesis and structure-stability relationships of a series of novel FK409 derivatives (1, 2, and 3) are described. The rates of decomposition in aqueous solution (pH 8.0, 30 degrees C) were parallel with those of spontaneous NO release measured by ESR spectroscopy using carboxy-PTIO. The compounds can cover a wide range of NO releasing rates by appropriate modification of the molecule.
