Disclosed herein is an osteopontin production inhibitor capable of preventing a disease resulting from increased production of osteopontin.
The osteopontin production inhibitor contains a dictyopyrone derivative or a dihydrodictyopyrone derivative as an active ingredient. The dictyopyrone derivative is preferably a compound represented by Chemical Formula 1 or 2, and the dihydrodictyopyrone derivative is preferably a compound represented by Chemical Formula 3 or 4.
secondary metabolites produced by cellular slime molds to evaluate if they are valuable resources for biologically potential substances. From the methanol extract of fruiting bodies of Dicyostelium firmibasis, we obtained new α-pyranoids, dihydrodictyopyrones A (1) and C (2). Their structures including absolute configurations were determined by spectral means and asymmetric total synthesis. Compounds 1 and
