متن کاملNew indole alkaloids from the North Sea bacterium Vibrio parahaemolyticus Bio249.
Several bis- and tris-indole derivatives were isolated from a North Sea bacterium that was closely related to Vibrio parahaemolyticus (98% homology). 1,1,3-Tris(3-indolyl)butane (3) is a new compound, and 3,3-bis(3-indolyl)butane-2-one (1a), arundine (1b), and 1,1,1-tris(3-indolyl)methane (2a) were isolated from a microorganism for the first time here. Additionally, many other known compounds w...
