Although all CDs complexed with NMDA or glutamate, only beta-, methylated beta- and sulfated beta-CDs displayed neuroprotective activity and lowered cellular cholesterol. Monnaert et.a. (JPET 310:7445-751, 2004) using an in vitro model of the blood-brain-barrier examined various cyclodextrin derivatives for their toxicity and permeability.

Gamma-cyclodextrin is a ring-shaped molecule made up of eight glucose units linked by alpha-1,4 bonds. Alpha-cyclodextrin, beta-cyclodextrin, and gamma-cyclodextrin are naturally occurring compounds derived from the degradation of starch by the glucosyltransferase enzyme (CGTase). They are formed naturally from bacteria and synthetically.

The natural cyclodextrins, in particular β-cyclodextrin, are of limited aqueous solubility meaning that complexes resulting from interaction of lipophiles with these cyclodextrin can be of limited solubility resulting in precipitation of solid cyclodextrin complexes from water and other aqueous systems.
their intact form. Hydrophilic cyclodextrins are considered non-toxic at low to moderate oral dosages. Lipophilic cyclodextrin derivatives, such as the methylated cyclodextrins, are to some extent absorbed from the gastrointestinal tract in to the systemic circulation and have been shown to be toxic after parenteral administration.
hydroxypropyl cyclodextrin mixtures, one takes full advantage of the formation of inclusion complexes (host-guest com- plexes), and lipophilic drugs can be dissolved and made freely and rapidly accessible for absorption into the organi~m.~-~ Hydroxypropyl cyclodextrins have very low toxicity by the
Summary. The acute oral and parenteral LD-50 of beta-cyclodextrin was established on rats, mice and dogs. The long term toxicity studies were performed on rats and dogs following the two weeks dose finding studies given the test substance by oral route.
