A series of substituted 5-benzyl-3-(1-carboxy-2-phenylethyl)hydantoins was prepared by condensation of aromatic aldehydes with the corresponding 5-unsubstituted hydantoin followed by reduction of the intermediate benzylidene derivative. The compounds were assessed as inhibitors of dihydro-orotatedehydrogenasefrom Clostridium oroticum. It was found that hydrophobic and electron-donating substituents
