Photosensitizer

Photosensitizer-3, a photosensitizer that generates single-linear oxygen upon near-infrared light excitation in combination with FAP, exhibited potent and selective killing of transfected HEK cells and affibody-targeted A431 cancer cells.

NFh-NMe-2 is a photosensitizer that interacts with nitroreductase (nitroreductase) to generate singlet oxygen in tumor cells, exhibiting cytotoxicity in cancer cells and inducing apoptosis (apoptosis). In mouse models, NFh-NMe-2 demonstrates antitumor activity.

TTQ-SA is a near-infrared spiraling aggregation-induced emitter capable of converting near-infrared light (NIR) into thermal energy, resulting in thermal damage and death of tumor cells. In cancer cells MF-7, TTQ-SA shows cell uptake and targeting capabilities. TTQ-SA binds with DNAzyme to inhibit the expression of the survivin gene, enhancing the sensitivity of tumor cells to photothermal therapy.

Type-I -II Photosensitizer-1 (compound 8b) is a photosensitizer with anticancer properties. It exhibits significant phototoxicity against A549 and 4T1 tumor cells. Under laser irradiation, Type-I -II Photosensitizer-1 demonstrates strong oxygen-independent antitumor activity with an IC50 ranging from 1.50 to 1.76 μM.

CAR-2 is a BODIPY-based photosensitizer that induces ferroptosis in photodynamic therapy (PDT) by targeting the endoplasmic reticulum (ER) and lipid droplets (LD). It exhibits phototoxicity against breast cancer cells with an IC50 of 0.01-0.02 μM and demonstrates antitumor efficacy in a 4T1 xenograft mouse model.

TBC-1 is a chlorophyll-a derivative that acts as a photosensitizer for photodynamic therapy (PDT). It efficiently generates type I ROS and targets the endoplasmic reticulum. TBC-1 demonstrates in vitro biocompatibility and PDT effectiveness under both normoxic and hypoxic conditions.
