Abstract

Synthesis of convolutamines and lutamides, new 2, 4, 6-tribromo-3-methoxyphenethylamine alkaloids isolated from Floridian marine bryozoan Amathia convoluta, was accomplished by a sequence of reactions starting from 3-hydroxyphenethylamines. Cytotoxities of the synthetic lutamides, convolutamines and their de-O-methyl derivatives were examined using drug-sensitive and-resistant P388 as well as KB cell lines. The bioassay suggests that the ...
