Abstract:
In a screening study on immunomodulatory fungal constituents, eleven new 2-pyrones tentatively named TT-1 (1), and TT-2-11 (2-11) have been isolated from a Fungi Imperfecti, Trichurus terrophilus, and designated rasfonin (1), and trichurusin B-K (2-11), respectively. Compounds 1-4 exhibited considerably high immunosuppressive activities, and compounds 8-11 have shown moderate ones. The structure-activity relationships of these constituents have also been discussed.
