We have designed novel small inhibitors of rabbit 20S proteasome using a trifluoromethyl-beta-hydrazino acid scaffold. Structural variations influenced their inhibition of the three types of active sites. Proteasome inhibition at the micromolar level was selective, calpain I and cathepsin B were not inhibited.
