Constitutive proteolytic activity of MALT1 is associated with highly aggressive B-cell lymphomas. Chemical tools that detect active MALT1 have been reported, but suffer from poor cell permeability and/or cross-reactivity with the cysteine protease cathepsin B. Here, we report that the non-natural amino acid pipecolinic acid in the P2 position of substrates and chemical probes leads to improved selectivity toward MALT1 and results in cell-permeable fluorescent probes.
