WebbNational Center for Biotechnology Information Webb30 juni 2024 · Derivatives of β-cyclodextrin have been developed to provide improved solubility while maintaining the high complexation efficiency of β-cyclodextrin, and include randomly methylated β-cyclodextrin , permethylated β-cyclodextrin , and 2-hydroxypropyl-β-cyclodextrin , and the unique properties of these hosts compared to the unmodified β …
WebbPreviously, midazolam has been solubilized with various cyclodextrin derivatives, including hydroxypropyl-, sulfobutyl-, and randomly methylated modifications of β-cyclodextrin [15,18]. However, the overall complexation efficacy for cyclodextrins is frequently low in order to solubilize even small amounts of any given benzodiazepine drug . WebbCyclodextrins (CDs) are water-soluble cyclic oligosaccharides produced by bacterial cyclodextrin glucanotransferase. 11 The host–guest chemistry of CDs, along with their amenability to synthetic modification, 12 has faciliated the fabrication of enzyme mimetic CDs, such as glycosidases, 13 esterases, 14 and proteases. 15 Randomly methylated α- …
