Description

Fenamidone (13; RPA 407213; (S)-5-methyl-2-methylthio- 5-phenyl-3-phenylamino-3,4-dihydroimidazol-4-one) is a complex III inhibitor that does not derive from the strobilurins but rather belongs to the imidazolinone chemical class. Fenamidone is a white woolly powder, with the following characteristics: mp = 137 C; water solubility = 7.8 mg/L; logP = 2.8, and vp = 3.4×107 Pa. It was first described by Mercer et al. (39) in 1998. Only the S-enantiomer shows antifungal activity, thus offering a reduction in application rates over the racemic mixture.
