Contrary to the fluoro-substituted compounds, in the case of the imidazolyl-derivatives shortening the linker chain from butyl- (compound IIIe) to ethyl- (compound IIIf), increased the inhibition potency.

The same regularity was observed when the compounds were tested as substrates towards TDT, where the potency of IIIf, bearing an ethyl-linker, was ∼100 times higher than that of IIIe bearing a butyl-linker.
