TPS genes were found in 6 species of sequenced amoeba, including Dictyostelium discoideum, D. purpureum, Cavenderia fasciculata (formerly D. fasciculatum), Tieghemostelium lacteum (formerly D. lacteum), Heterostelium album (formerly Polysphondylium pallidum), and Actyostelium subglobosum [14

• activate glorin-induced genes in the social amoeba Polysphondylium pallidum was evaluated by quantitative reverse transcription PCR, whereby both compounds showed bioactivity comparable to a glorin standard. This synthetic route will be useful in conducting detailed structure–activity relationship studies

• numerous species of social amoebae such as Polysphondylium pallidum, Dictyostelium fasciculatum [11], and D. caveatum [12], amongst others respond chemotactically to glorin (1), the acrasin has only been isolated from P. violaceum [13]. Despite its crucial role in the initiation of multicellularity, little
