A series of novel difluoroketones with low molecular weight (less than 600 m.u.) and which are potent inhibitors of the HIV-1 protease (IC50 = 1.0 to 21 nM) were synthesized. These compounds also exhibited antiviral activity by inhibition of the cytopathic effect of HIV-1(3)B in MT-4 cells in vitro.
