Photocytotoxicity index
WebThe photocytotoxicity index (PI) values of RuH were determined to be 73 and 13 under normoxia and hypoxia by calculating the ratio of (IC 50) Dark/(IC 50) Light.For RuCN, the (IC 50) Light values were 4.4 ± 0.6 and 14.9 ± 0.9 μM under normoxia and hypoxia, respectively. The PI values were 42 and 12 under normoxia and hyp-oxia, respectively ... WebSignificance. Photodynamic therapy is a noninvasive medical procedure in which malignant tissue is damaged by reactive oxygen species generated from targeted light irradiation on a photosensitizer. Herein, we incorporate an Ru (II)-based two-photon photosensitizer into a macrocyclic structure via coordination-driven self-assembly.
