Compound PS-I (Photosensitizer-4) is an effective photosensitizer that can efficiently kill cancer cells and inhibit tumor growth under light exposure.

Compound Ru2 (Antitumor photosensitizer-6) exhibits synergistic type I/II photosensitization and photocatalytic activities under illumination at 595 nm. It causes oxidative redox imbalance within cells, affecting biosynthesis and metabolic processes, leading to cell apoptosis (Apoptosis). Compound Ru2 is applicable in studies of photodynamic therapy (PDT).

Verteporfin (BPD-MA) is a YAP inhibitor that inhibits YAP-TEAD interactions. Verteporfin is also a photosensitizer used in photodynamic therapy. Verteporfin also induces apoptosis and inhibits autophagy.

Pyridinium bisretinoid A2E (A2E) is a fluorescent chromophore isolated from lipofuscin in retinal pigment epithelium, a lipophilic cation and weak photosensitizer with cytotoxicity.
