Sulphobutylether-?-cyclodextrin (SBE-?-CD) is used as an adjuvant to improve the solubility and stability of a number of active pharmaceutical ingredients, including the antifungal agent voriconazole. In collaboration with Professor Steve Wicks and his team at the University of Greenwich, Curadev developed a new method for the production of sulfoalkyl ether-?-cyclodextrins. The method also enabled the production of SBE-?-CD with a high average degree of substitution (ADS), which was previously not possible. This is particularly beneficial as it is believed that increasing the ADD of SBE-?-CD will decrease its toxicity. Curadev applied for and received on April 18 , 2018a European patent protecting both the process for the preparation of SBE-?-CD and the novel SBE-?-CD compositions per se with a high (ADS).
