Pericosines A-E 1-5 have been isolated from a strain of Periconia byssoides originally separated from the sea hare Aplysia kurodai. Among them, pericosines C 3 and E 5 were separated as enantiomeric mixtures. Their stereostructures, except for compound 1, have been elucidated or identified on the basis of spectroscopic analyses, including 1D and 2D NMR(More)
Macrosphelide L has been isolated from a strain of Periconia byssoides originally separated from the sea hare Aplysia kurodai, and the absolute stereostructures of this material and macrosphelide H, previously undetermined, have been elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques and some chemical transformation. (R)-Methyl(More)
Peribysins A-D 1-4, including a new type of furanofuran, have been isolated from a strain of Periconia byssoides originally separated from the sea hare Aplysia kurodai, and their relative stereostructures have been elucidated on the basis of NMR spectral analyses. All these metabolites potently inhibited the adhesion of human-leukemia HL-60 cells to HUVEC.(More)
We carried out a randomized joint study on endocrine therapy and endocrine chemotherapy for prostatic cancer at our department and 17 affiliated institutions. Of 80 patients entered, 39 patients were treated with chlormadinone acetate alone (group A) and 41 patients were treated with chlormadinone acetate in combination with UFT (group B). After excluding(More)
