Pestalotin is a pyran-2-one metabolite produced by Pencillium decumbens. Pestalotin is a gibberellin synergist and plant growth stimulator. Pestalotin does not influence elongation of rice seedlings when given alone, but acts synergistically to enhance gibberellic acid-induced elongation.
During the course of screening gibberellin synergists, researchers at the Dept. of Agricultural Chemistry (University of Tokyo) Tokyo, Japan isolated the active principle Pestalotin from culture fultrate of a phytopathogenic fungus, Pestalotia cryptomeriaecola (Kimura et al, 1971).
Pestalotin is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.
