A new inhibitor of mammalian adenosine triphosphatases, designated aqu
astatin A, has been isolated from a fungus identified as Fusarium aqua
eductuum. The structure of this compound has been determined by MS and
NMR analyses. It inhibits Na+/K+-ATPase with an IC50 value of 7.1 muM
, and H+/K+-ATPase with an apparent IC50 value of 6.2 muM.
