Research Abstract

This research program from 1991 to 1993 provided three important pieces of evidence, as follows.
1. Discovery of a new antifungal and anticancer agent, Echinoclasterol sulfate.
From the Australian Institute of Marine Science, 25 marine organisms were mailed to Japan and their extracts were subjected to various assay systems. The water soluble fraction of the MeOH extract of the marine sponge, Echinoclathria subhispida, showed a strong antifungal activity against Mortierella remannianus. The active principle was isolated and characterized as the first phenathylammonium salt of a novel polyoxygenated sterol sulfate, named "Echinoclasterol sulfate". Echinoclasterol sulfate also showed an inhibitory effect on cell growth of PC-9, a lung cancer cell line, dose-dependently. The IC_<50> value was 600 muM. Its anticancer activity is about 300 times weaker than adriamycin.
2. Isolation of a new antioxidant.
An edible algae, Nori Porphyra tenera, contains shinorine, which does not have any antioxidant activity itself. However, the enzyme fraction obtained from a marine organism converted shinorine to a new antioxidant, mycosporine-glycine. A method of large scale preparation of mycosporine-glycine is now under investigation.
3. Computer assisted molecular modeling of the okadaic acid class compounds.
Three okadaic acid class compounds, okadaic acid, calyculin A, and microcystin-LR, are potent inhibitors of protein phosphatases 1 and 2A. Although their structures are not related to each other, they were assumed to bind to same site of a catalytic subunit of the protein phosphatases. Computer assisted molecular modeling revealed that three okadaic acid class compounds have common structural features, such as the central core of the molecules, for the inhibitory activity and non-polar side chains for binding activity.
