Preliminary studies demonstrate enhanced cytotoxicity of benzoporphyrin in cancer treatment, suggesting promising applications.

The aim is to evaluate the phototoxicity of benzoporphyrin derivative (BPD) compared to hematoporphyrin (HP) in various human and mouse cell lines.
Tested phototoxicity of BPD and HP in vitro on human adherent and nonadherent cell lines.
Conducted light activation for 1 hour to measure cytotoxic effects of both agents.
Assessed cell viability at varying concentrations of BPD and HP across different cell types.
BPD was found to be 10 times more cytotoxic than HP against human adherent lung cancer cell lines.
For nonadherent cells, BPD was 10-70 times more effective than HP.
The concentrations required to kill 100% of cells ranged from 10 to 500 ng BPD/ml and 0.2 to 10 μg HP/ml.
BPD's maximum absorption peak at 700 nm suggests better tissue penetration compared to HP.

Richter et al. (1987) studied this question.
