  摘要：

  The structure of the prespore-cell-promoting factor from Dictyostelium discoideum was determined to be 2-hydroxy-5-methyl-6-pentylbenzoquinone. The synthetic compound has prespore-cell-promoting activity similar to the natural one, with half-maximal induction at a concentration as low as 40 pM. It was also found that the factor induces aggregation in an aggregation-deficient mutant of a related species, Polysphodilium violaceum. Both these activities are sensitive to positional isomerism with the 6-methyl-5-pentyl isomer showing no detectable activity.

  4-Methyl-5-pentylbenzene-1,3-diol (MPBD) is a secondary metabolite of SteelyA polyketide synthase, which controls cell aggregation and spore maturation of Dictyostelium discoideum. In this study, chemical synthesis of MPBD and its derivatives was achieved. Structure–activity relationship (SAR) studies for antimicrobial activities against Escherichia coli and Bacillus subtilis were also conducted.

  A method and cell line for producing polyketides in yeast. The method applies, and the cell line includes, a yeast cell transformed with a polyketide synthase coding sequence. The polyketide synthase enzyme catalyzes synthesis of olivetol or methyl-olivetol, and may include Dictyostelium discoideum polyketide synthase (“DiPKS”). Wild type DiPKS produces methyl-olivetol only. DiPKS may be modified to produce olivetol only or a mixture of both olivetol and methyl-olivetol. The yeast cell may be modified to include a phosphopantethienyl transferase for increased activity of DiPKS. The yeast cell may be modified to mitigate mitochondrial acetaldehyde catabolism for increasing malonyl-CoA available for synthesizing olivetol or methyl-olivetol.

• REDUCTION OF BETA-AMYLOID LEVELS BY TREATMENT WITH THE SMALL MOLECULE DIFFERENTIATION-INDUCING FACTOR

  The present invention relates to novel uses for a family of small molecules, Differentiation-Inducing Factors (DIFs). It has been discovered that DIFs surprisingly can alter the metabolic processing of amyloid precursor protein (APP) and in turn reduce the level of secreted Aβ. The metabolic processing of other γ-secretase substrates normally present in cells (Notch and APLP1) is not affected when treated with DIF. The invention provides methods for reducing Aβ production in mammalian cells that express APP by administering DIF-I, DIF-2, DIF-3, a functionally equivalent analog and or any combination thereof. The invention also provides methods for treating and/or preventing Alzheimer's disease by preferentially reducing Aβ production.
