5-Aminolevulinic acid (5-ALA) and its two esterderivatives (5-ALA-OMe and 5-ALA-OHex) have been approved for photodiagnosis and photodynamic therapy (PDT) of tumors in the clinical. However, their pharmacological activities are limited by their instability under physiological conditions and lack of tumor selectivity. With the aim to overcome these shortcomings, a glutathione-responsive 5-ALA derivative (SA) was
