A1B3 Porphyrin

A1B3 Porphyrins are primarily used in biomedicine to develop targeted photodynamic therapy (PDT) drugs and multimodal imaging probes. Their key advantage lies in the flexible modifiability provided by their asymmetric structure, allowing efficient conjugation via a single functional group (e.g., Acid, Amine, NHS) to targeting molecules (such as antibodies or peptides), PEG chains, or diagnostic agents, thereby achieving higher tumor selectivity and reduced background toxicity.
