These amphiphilic macrocyclic derivatives have the ability to self-assemble in aqueous solvent forming micelles or vesicles and can be used as hosts for the solubilisation and/or stabilisation of various compounds. Embodiments of the present invention utilise macrocyclic oligosaccharides and preferably cyclodextrin as the macrocyclic derivatives to be modified.

Why it's free to use
- Filed April 30, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 30, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
