---|---|---|
57% | A solutionof 0.5 g ATS (1.2 mmol), 0.4 g EDCI (2.0 mmol), and 0.3 g NHS(2.3 mmol) in DMF (20 mL) was stirred for 45 min in an ice bath,then 1.1 g 1N-bCD (1.0 mmol) was added to the reaction. Themixture was allowed to react for additional 2 h in an ice bathand subsequently for 15 h at room temperature. After the reactionwas completed, the solution was removed by a rotary evaporator,and followed by the addition of double-distilled water.The clear solution was collected by filtration, and then waspoured into acetone. The precipitate was collected and purifiedon a Sephadex LH-20 column with aqueous solution as eluent.The synthetic procedures for mono(6-artesunate-ethylenediamino-6-deoxy)-b-cyclodextrin (ATS-2NbetaCD), mono(6-artesunate-diethylenetriamino-6-deoxy)-b-cyclodextrin (ATS-3NbetaCD),and mono(6-artesunate-triethylenetetraamino-6-deoxy)-b-cyclodextrin(ATS-4NbetaCD) were similar to the ATS-1NbetaCD describedabove. |
