The Myxomycetes (true slime molds) are an unusual group of primitive organisms that may be assigned to one of the lowest classes of eukaryotes. As their fruit bodies are very small and it is very difficult to collect much quantity of slime molds, few studies have been made on the chemistry of myxomycetes. Cultivation of the plasmodium of myxomycetes in a practical scale is known only for very limited species such as Physarum polycephalum. Cultivation of other myxomycetes for natural products chemistry studies had never been reported. We recently collected the fruit bodies of the myxomycetes (120 species, 292 strains) in Japan, and laboratory-cultivation of these myxomycetes were investigated. Spore germination was observed for 81 strains on an agar medium. Among them 34 strains were able to develop into the plasmodial stage, and 14 strains successfully showed formation of fruit bodies from the cultured plasmodia in a plate agar medium. Chemical constituents of cultured plasmodia of Didymium minus and Didymium bahiense var. bahiense were examined to obtain several sterols (1-7), pyrroloiminoquinone pigments (8 and 9), and new glycerolipid (10). Constituents in fruit bodies were found to be different from those of the plasmodial stage. We also investigated chemical constituents of the field-collected samples of fruit bodies of Lindbladia tubulina to isolate naphtoquinone pigments, lindbladione (11) and its O-methyl derivatives (11 and 12).
