  • Fungal strain acremonium sp.MT70646(KCTC 0916BP), novel compounds produced by this strain and their use
    Patent number: 7060714
    Abstract: The invention is aimed at discovering a new type of anti-cancer compound which can exert an excellent inhibitory activity against the heparanase. A fungal strain Acremonium sp. MT70646 (KCTC 8973P) was isolated from the soil. From the culture of the isolated fungal strain, novel compounds that can inhibit both heparinase and heparanase was purified. Therefore, the present invention regards to provide a newly isolated fungal strain Acremonium sp. MT70646 (KCTC 8973P), its new products, and pharmaceutical agents such as a heparinase inhibitor, a heparanase inhibitor, a metastasis inhibitor and an angeiogenesis inhibitor all of which contain the above new compounds produced by the fungal strain as an active ingredient.
