研究了硫氢化物(SH-)与含吡啶键的环糊精二聚体(MET-hemCD3)和铁(III)-卟啉组成的血红蛋白模型化合物的反应。在无氧中性水溶液中，MET-hemCD3形成稳定的(SH-)-MET-hemCD3络合物。在O-2存在下，(SH-)-MET-hemCD3(Fe(III))和O-2-hemCD3(Fe(II))之间发生了可逆的配体交换。
The reaction between hydrosulphide (SH-) and a haemoglobin model compound, composed of a Fe(III)-porphyrin and a cyclodextrin dimer possessing a pyridine-linker (met-hemoCD3), was studied. Met-hemoCD3 formed a stable (SH-)-met-hemoCD3 complex in oxygen-free neutral aqueous solution. In the presence of O-2, reversible ligand exchange between (SH-)-met-hemoCD3 (Fe(III)) and O-2-hemoCD3 (Fe(II)) occurred.
