Several P-carboHne alkaloids related to eudistomins were isolated from Eudistoma glaucus and other species of Eudistoma, such as E. album, E.fragum, and E. gUboverde. Generally, these derivatives have antiviral and antitumor activities similar to those of eudistomins, but eudistomi-din A is also an antagonist of calmodulin (Kobayashi, Nakamura, and Ohizumi, 1986). Some members of this series are presented in Figure 28.21.
