Per(3-deoxy)-α-cyclo­mannin: an n-butanol hexahydrate inclusion complex (31)

H. J. Lindner, F. W. Lichtenthaler, K. Fujita, C. Yang, D.-Q. Yuan and Y. Nogami

The host molecule in the title compound, cyclo­hexakis­[(1Per(3-deoxy)-α-cyclo­mannin: an n-butanol hexahydrate inclusion complex (32)4)-3-deoxy-α-D-arabino-hexo­pyran­osyl] n-butanol hexahydrate, C36H60O24·C4H10O·6H2O, has a cavity similar in diameter but smaller in torus height than that of α-cyclo­dextrin, due to the axial C-2-hydroxyl groups pointing away from the ring plane. The mol­ecules have approximate C6 symmetry and pack into stacks with channels occupied by disordered n-butanol mol­ecules. Water of srystallization fills the space between the stacks. The structure was determined at 211 K.

Special details

top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)are estimated using the full covariance matrix. The cell e.s.d.'s are takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused when they are defined by crystal symmetry. An approximate (isotropic)treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factorwR and goodness of fit S are based on F2, conventionalR-factors R are based on F, with F set to zero fornegative F2. The threshold expression of F2 >σ(F2) is used only for calculating R-factors(gt) etc.and is not relevant to the choice of reflections for refinement.R-factors based on F2 are statistically about twice as largeas those based on F, and R- factors based on ALL data will beeven larger.

Per(3-deoxy)-α-cyclo­mannin: an n-butanol hexahydrate inclusion complex (2024)

FAQs

What is cyclodextrin inclusion complex? ›

Cyclodextrins have an internal non-polar hole and hydroxyl groups placed on the surface, the inclusion of hydrophobic compounds takes place mainly by hydrophobic interactions between guest molecules and the walls of cyclodextrin cavity [5].

What is cyclodextrin used for? ›

In nearly every formulation intended for any route, the basic purpose of cyclodextrin is to manage the solubility, increase bioavailability, and increase the solubility. Literature reveals that cyclodextrin is also being used in the development of novel carriers like liposomes, microspheres, nanoparticles, etc.

How to complex with cyclodextrin? ›

Solvent-Based Methods

Co-precipitation is a simple and cost-effective technique. b. Kneading Method: In this technique, the cyclodextrin and guest molecule are mixed with a small amount of solvent and kneaded to form a viscous mass. The solvent is then evaporated, resulting in the formation of a solid complex.

What is the application of inclusion complex in pharmacy? ›

The formation of inclusion complexes between drugs and natural or modified cyclodextrins increases aqueous solubility and improves the bioavailability of drugs [23,24,25,26].

Can cyclodextrin remove plaque from arteries? ›

Conclusions: Targeted removal of 7KC from plaque with proprietary cyclodextrin compounds has the potential to prevent and reverse the formation of atheroscloertic plaques. This innovation represents the first disease-modifying therapeutic approach to treating atherosclerosis.

Is cyclodextrin safe for humans? ›

Alpha-, beta-, and gamma-cyclodextrin are all generally recognized as safe by the U.S. FDA. They have been applied for delivery of a variety of drugs, including hydrocortisone, prostaglandin, nitroglycerin, itraconazole, chloramphenicol. The cyclodextrin confers solubility and stability to these drugs.

What is alpha-cyclodextrin good for? ›

The intakes of α-CDs are related to positive physiological effects, such as weight loss, reducing serum triglycerides and leptin levels, improving insulin sensitivity and increasing the volume of fecal fat in rats (Artiss, Brogan, Brucal, Moghaddam, & Jen, 2006).

What is the disadvantage of cyclodextrin? ›

In spite of these above advantages, cyclodextrin also has some limitations. For example, when β-cyclodextrin interacts with cholesterol it forms a low soluble complex that may have a nephrotoxic impact.

Do cyclodextrins remove cholesterol? ›

CDs can form inclusion complexes with cholesterol, in which the cholesterol molecule is trapped inside the CD cavity. This complexation results in enhancing the solubility of cholesterol, which can facilitate its removal from the body2,3,4.

What are the hazards of cyclodextrin? ›

Eye: May cause eye irritation. Skin: May cause skin irritation. Ingestion: May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated.

How drug is released from cyclodextrin? ›

Dissociation due to dilution appears to be the major release mechanism although other factors such as competitive displacement of the drug from the complex, drug binding to plasma and tissue components, uptake of the drug by tissues not available to the complex or cyclodextrin, and cyclodextrin elimination may also ...

How much beta cyclodextrin should I take? ›

β-Cyclodextrin is a non-reducing cyclic oligosaccharide consisting of seven α-1,4-linked d-glucopyranosyl units. The Scientific Committee on Food (SCF) allocated an acceptable daily intake (ADI) of 5 mg/kg body weight (bw) per day to β-cyclodextrin (E 459) in 1996.

What are inclusion complexes also known as? ›

In host–guest chemistry, an inclusion compound (also known as an inclusion complex) is a chemical complex in which one chemical compound (the "host") has a cavity into which a "guest" compound can be accommodated.

What are the advantages of inclusion complexes? ›

Advantages of Cyclodextrin Inclusion Complexation

Reduction of irritation: Drug substances that irritate the stomach, skin or eye can be encapsulated within a CD cavity to reduce their irritancy. Inclusion complexation with CDs reduces the local concentration of the free drug, below the irritancy threshold.

Why is inclusion complex? ›

Definition: A complex in which one component (the host) forms a cavity or, in the case of a crystal, a crystal lattice containing spaces in the shape of long tunnels or channels in which molecular entities of a second chemical species (the guest) are located.
