Abstract
Two new (2-phenylethyl)amine alkaloids, convolutamines F and G, and a dibro mohydroxyoxindole alkaloid, convolutamydine E, have been isolated from the butan-1-ol soluble material of the Floridian marine bryozoan Amathia convol uta. Their structures were elucidated on the basis of spectroscopic data. C onvolutamine F exhibited activity against KB, KB/VJ-300, and U937 cells. Th is compound also exhibited the inhibitory effects for cell division of fert ilized sea urchin eggs.
