This invention relates to the discovery of 5-substituted analogues of the selective platelet lowering agent anagrelide, which are extremely potent inhibitors of phosphodiesterase III (PDE III). The compounds are potentially useful agents for the treatment of conditions in which the inhibition of PDE III in beneficial. Formula (I): wherein: R1 is independently selected form C1-6 alkyl or C1-6haloalkyl; R2 is selected from hydrogen, C1-6alkyl or C1-6haloalkyl; and X1 and X2 are each independently halo.
