“…Each collection was kept separate, preserved by our standard procedure and then returned to UCSC for extraction with MeOH. Purification of the crude oil from one representative sample of the CH2C12 solvent partition fraction yielded phenylacetic acid which was accompanied by known DKPs, cyc/0-(S-Pro-i?-Leu) [1] (11)(12)(13); cyf/o-(5-Pro-5-Ile) [2] (11); cyclo-{S-?to-R-VÚ) 'Novel Sponge-Derived Amino Acids, 18 [ ] +128°.…”

The cyanobacteria-containing Caribbean sponge, Calyx cf. podatypa, was collected from three sites in the Bahamas. In each of the three collections, a polar solvent partition fraction contained six known compounds including five diketopiperazines [1-4,6] and phenylacetic acid, along with a new diketopiperazine, cyclo-(4-methyl-R-proline-S-norvaline) [5]. Interestingly, all six diketopiperazines are proline-derived cyclic dipeptides. This is the first example for this class of peptide derivative to be isolated from a Calyx sponge. Parallel studies of one of the sponge collections in which the ectosome (cyanobacteria-rich) was separated from the endosome (no cyanobacteria) revealed no significant differences in their content of diketopiperazines.
