Application:	(2-Hydroxypropyl)-β-cyclodextrin can be used: • In the preparation of imidazole nucleosides via enzymatic transglycosylation to improve the solubility and/or stability of 4-aryl and 4-heteroaryl-1H-imidazole reactants. • Cyanazine-hydroxypropyl-β-cyclodextrin inclusion complex with enhanced water solubility when compared to cyanazine.
Application:	The solubility of lipophilic drugs increases linearly with the concentration of hydroxypropyl-β-cyclodextrin (HBC) in aqueous solution because of the complex between HBC and the drug. This guest-host type complex is formed between the drug and the non-polar cavity in the HBC that results in enhanced solubility. Solutions may be lyophilized to produce freely soluble powders. Non-toxic in rabbits and mice.
