Abstract

NEW MATERIAL:An okadaic acid shown by the formula (R is carboxy or esterified carboxy), its salt, and its ester.
EXAMPLE: Okadaic acid P-bromophenacyl ester.
USE: An antitumor agent, cardiotonic, etc. Pharmaceutically manufactured into an oral agent, injection, external preparation, etc. for use. A dose as the antitumor agent for human is about 2W50γ/kg/day.
PROCESS: For example, Halichondria Okadai PORIFERA is extracted with an organic solvent (e.g., methanol, ethanol, etc.) to give an extracted solution, from which an odakaic acid shown by the formula (R is carboxy) is isolated and collected. And, if necessary, esterification or salt formation is carried out.
