However, its therapeutic effect is severely limited by the insufficient oxygen supply and high glutathione (GSH) concentration in the tumor environment. Recently, nitric oxide (NO) has been widely used as a physiological regulatory factor and tumor inhibitor in various pathological processes. NO can kill tumor cells by reacting with O<small><sub>2</sub></small>˙<small><sup>−</sup></small> to produce highly lethal ONOO<small><sup>−</sup></small>. Importantly, NO can promote vasodilation to improve hypoxia in the tumor environment and interfere with the antioxidant defense of GSH, improve the sensitivity of the tumor to ROS, and enhance the effect of PDT. However, since NO has a very short half-life and is gaseous, it cannot be used directly in the clinic.
