摘要：

Four new cyclic peptides, keraammides E(1), G(2), H(3), and J(4), containing an oxazole or a thiazole ring have been isolated From the Okinawan marine sponge Theonella sp, and the structures elucidated by 2D NMR data and degradation experiments. The sequence of amino acid residues in 1 - 4 was determined on the basis of FAB MS/MS data.
