In its broadest aspect, a method for treating a mammalian patient at risk or suffering from a disease caused by a kinetoplastid parasite comprises administering to such subject an effective kinetoplasticidal amount of an imido-substituted 1,4- naphthoquinone to inhibit the kinetoplastid. In an important aspect, a method of inhibiting Trypanosoma cruzi comprises administering to a patient for prophylaxis or to a patient in need of treatment an antitrypanosomal effective amount of an imido-substituted 1 A-naphthoquinone.

present a detailed systematic study of the synthesis and ability of fluorinated 2-phenyl-2-oxazolines to undergo polymerization. The synthesis of these compounds is based on a two-step procedure that gives the desired 2-oxazolines in moderate-to-good yields. All the compounds were fully characterized by IR and NMR ((1)H, (13)C, and (19)F) spectroscopy, massspectrometry, and elemental analysis. The
