This invention relates to a novel pharmacologically active substance, fluoriaspondin. During their search for new pharmacologically active substances from marine products, the inventors succeeded in isolating a new substance from Okinawan sponges that has an inhibitory effect on granulation tissue proliferation, and as a result of further research, they completed this invention. . The fluoriaspondin of this invention has the following planar chemical structure. The phyllospondin of the present invention can be produced, for example, by extraction from Okinawan sponges [phyllospongia foliascence (pallas)]. For the production of fluoriaspondin from Okinawan sponges, for example, Okinawan sponges are mixed with organic solvents such as alcohols such as methanol, ethanol, n-propanol, and n-butanol, acetone, pyridine, ethyl acetate, or mixtures thereof. It can be obtained by extraction with a mixed solvent of an organic solvent and water, and isolation and collection from the resulting extract. In order to isolate fluoriaspondin from the extract, known means generally used for isolating natural products are applied. That is, first, the extract is concentrated, and the resulting concentrated liquid is used to determine the difference in distribution between the two liquid phases, the difference in adsorption affinity to various adsorbents, and the difference in solubility and precipitation rate in appropriate solvents. The desired active ingredient, fluoriaspondin, is isolated using a method such as the following, purified, and further crystallized using a suitable solvent to obtain crystals of fluoriaspondin. The physicochemical properties of the thus obtained fluoriaspondin are as follows.

(1967)], the eggshell and eggshell membrane were excised, and a paper disk with a diameter of 9 mm was placed on the chorioallantoic membrane. The open shell part was then closed with cellophane tape, and after incubation for an additional 4 days, the chorioallantoic membrane was cut out along the paper disk and dried at 60°C for 12 hours. Weigh this accurately,
The paper disk weight was subtracted to obtain the granulation weight, and the effect was determined based on the inhibition rate and statistical significance of the drug administration group relative to the control group. The liquid is dissolved in an organic solvent and impregnated with 20μ per paper disk.
Furthermore, the solvent is removed under reduced pressure before use.
