Figure 2 Activation and pH-dependent cyclization of dipeptidyl boroLeu. A tumor-specific protease recognition sequence (TSPRS) is attached to the N-terminus of the dipeptidyl boroLeu. The dipeptidyl boroLeu is released in its active form by a tumor-specific protease and undergoes a pH-dependent cyclization equilibrium. In the present study, low pH = 2 and mid pH = 7.6.
