We know that, Cyclodextrins (sometimes called cycloamyloses) are a family of compounds made up of sugar molecules bound together in a ring (cyclic oligosaccharides). Cyclodextrins are produced from starch by means of enzymatic conversion. They are used in food, pharmaceutical,drug delivery,  and chemical industries, as well as agriculture and environmental  engineering. Hydroxypropyl Beta Cyclodextrin (HPβCD) is the chief active  compound found in Procter and Gamble's deodorizing product "Febreze" under the brand name "Clenzaire".Cyclodextrins are composed of 5 or more α-D-glucopyranoside units linked 1->4, as in amylose (a fragment of starch).  The 5-membered macrocycle is not natural. Recently, the largest  well-characterized cyclodextrin contains 32 1,4-anhydroglucopyranoside  units, while as a poorly characterized mixture, at least 150-membered  cyclic oligosaccharides are also known. Typical cyclodextrins contain a  number of glucose monomers ranging from six to eight units in a ring, creating a cone shape.
A  clinical trial to evaluate a drug candidate called cyclodextrin as a  possible  treatment for Niemann-Pick disease type C1 (NPC), a rare and  fatal genetic disease has already started on 23rd Jan, 2012.  Scientists from the NIH’s  National Center for Advancing Translational  Sciences (NCATS) and the Eunice  Kennedy Shriver National  Institute of Child Health and Human Development  (NICHD) will conduct  the clinical trial at the NIH Clinical Center. Reaching  this trial  stage required collaboration among government, industry, patient   advocacy groups and academic researchers.
