Metabolite Identification
Common NamePederin
DescriptionPederin belongs to the class of organic compounds known as ketals. These are acetals derived from ketones by replacement of the oxo group by two hydrocarbyloxy groups R2C(OR)2 ( R not Hydrogen ). This term, once abandoned, has been reinstated as a subclass of acetals. The final steps of the synthesis of pederin are shown to the right. These measures can significantly reduce the physical effects the toxin has on the affected area. This is a rash that varies from a slight erythema to severe blistering, depending on the concentration and duration of exposure. Pederin is an extremely weak basic (essentially neutral) compound (based on its pKa). This step gives an 88% yield. Application of a topical steroid is also recommended for more intense exposures. One derivative of pederin, psymberin, has been found to be highly selective in targeting solid tumor cells.
