Cyclodextrin-Coupled Protoporphyrinatoiron Complex and Its Semi-Stable Oxygen Adduct Formation in an Aqueous Medium
Protoporphinatoiron IX was coupled with α-cyclodextrin on its secondary hydroxy groups side with three urethane bonds. This cyclodextrin-coupled porphinatoiron shows reduced acute toxicity and forms an oxygen adduct in cooled aqueous medium.
