Metabolite Identification
Common Name(±)-Fenarimol
DescriptionFenarimol, also known as rubigan-4 or rubigan 12 rc, is a member of the class of compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Fenarimol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Within the cell, fenarimol is primarily located in the membrane (predicted from logP). Fenarimol is a non-carcinogenic (not listed by IARC) potentially toxic compound. Fenarimol, sold under the tradenames Bloc, Rimidin and Rubigan, is a fungicide which acts against rusts, blackspot and mildew fungi. It is used on ornamental plants, trees, lawns, tomatoes, peppers, eggplants, cucumbers and melons. It is mainly used to control powdery mildew. It works by inhibiting the fungus's biosynthesis of important steroid molecules (Wikipedia). Fenarimol is an antiandrogen. It has effects on the reproductive organs and prostate gene expression levels. Studies suggested that the adverse effects of Fenarimol in males are mediated at least partialy via antagonism or androgen receptor (T3DB) (±)-Fenarimol is an Agricultural and horticultural fungicide..
