| Research Abstract |
YAMAZAKI ISOLATED 13 IMMUNOSUPPRESSIVE COMPONENTS INCLUDING 12 NEW ONES,3 MONOAMINE OXIDASE INHIBITORY COMPONENTS,AND 3 NEUROTROPIC COMPONENTS FROM SOME ASCOMYCETES INCLUDING GELASINOSPORA MULTIFORIS,MYCELIA STERILIA DERIVED FROM GELASINOSPORA PSEUDORETICULATA,AND SO ON.OHTA ISOLATED SOME ANTITUMOR AND cAMP PHOSPHODIESTERASE-INHIBITORY COMPONENTS FROM SOME BASIDIOMYCETES INCLUDING RUSSULA SUBNIGRICANS,AND SO ON.IWASAKI INVESTIGATED STRUCTURE-ACTIVITY RELATIONSHIP AND FUNCTIONAL MECHANISM OF SOME NATURAL PRODUCTS HAVING POTENCY TO INHIBIT MICROTUBULE ASSEMBLY,USTILOXIN A FROM A FUNGUS USTILAGINOIDEA VIRENS,ARENASTATIN A FROM A SPONGE DYSIDEA ARENARIA,AND SO ON.TANAKA ISOLATED 4 NOVEL INHIBITORS AGAINST GP120-CD4 BINDING INCLUDING ISOCHROMOPHILONES I AND II FROM PENICILLIUM MULTICOLOR.NAKAGAWA ISOLATED ALGINATELYASE FROM BACILLUS SP.AND PENICILLIC ACID FROM A FILAMENTOUS FUNGUS AS AN INHIBITING PRINCIPLE AGAINST ALGINATE PRODUCTION.IIDA ELUCIDATED THAT THE INFLUX OF Ca^<++> INTO CELLS THROUGH ION CHANNELS FORMED FROM STIMULATION OF TRICHOSPORINS,PEPTAIBOLS FROM A FUNGI IMPERFECTI TRICHODERMA POLYSPORUM,INDUCED CATECHOLAMINE RELEASE.NAGAO ACCOMPLISHED ASYMMETRIC TOTAL SYNTHESIS OF A POTENT IMMUNOSUPPRESSIVE PRINCIPLE FROM AN ASCOMYCETE,ISARIA SINCLAIRII BY MEANS OF A NEWLY DEVELOPED SYNTHETIC METHOD.NAKATA WAS SUCCESSFUL IN TOTAL SYNTHESIS OF MICALAMIDE A,AN ANTITUMOR COMPONENT FROM A MICALE SPONGE,AND HEMIBREVETOXIN B,A TOXIC PRINCIPLE OF A RED TIDE MICROORGANISM,GYMNODIUM BREVE.
