“…The I-phcnetyl-2-methylimidazolc is complexed by a-CD, and this complcx forms a stable pentacoordinated complcx with iron(I1)-protoporphyrin IX. This double complex formcd a stable oxygen acfduct in aqueous D M F solution at -30°C [33]. The a-CD capped by protoporphyrin IX Fe(I1) is less toxic than the hemin, the i. v. administered CD-protoporphyrin resulted in an LDSo valuc of more than 450 mg/kg, while the LDjo of i. v. administered hcmin is YO mg/kg in rats 1341.…”

Organic ligand containing coordination metal ion complexes and the organometallic compounds in which the metal atoms are covalently bound can form regular inclusion complexes with cyclodextrins. Organic ligands for complexation of the metal ions may be also appropriate substituent groups of a chemically modified cyclodextrin. With non‐derivatised cyclodextrins only so‐called Outer Sphere Hydroxo‐complexes are formed. Metallocenes, arenes, rotaxanes, rhodium‐ and platinum‐complexes are the typical metal ion or atom containing guest molecules. These complexes can be utilised as catalysts, enzyme models, siderophores, colour and fluorescence enhancing reagents, drugs, etc.

“…The first trace of non-covalent interactions involving CDs and porphyrins dates back to the early 80s and the work of Tsuchida. 21 In this seminal work, a series of N-substituted 2methylimidazoles, which are both good axial ligands for metalloporphyrins and good guests for α-CDs, were used to form ternary complexes of imidazole, CD and protoporphyrin IX (heme), as shown in Figure 6. The association constants for the binding of the encapsulated imidazole to the iron porphyrin are 15 to 30 times higher than for the same imidazoles in the absence of the CD.…”
