| | CUCURBIT(8)URIL Usage And Synthesis |
| Uses | Cucurbit[8]uril hydrate can be used as ananocontainer in a polyelectrolyte multilayer film. | | Definition | ChEBI: Cucurbit[8]uril is a cucurbituril. | | Synthesis | General procedure for the synthesis of cucurbit[n]uril from glyburide and diethoxymethane: Unsubstituted glyburide (19.94 g) and pure methanesulfonic acid (82 mL) were added to a reaction flask and heated to 80 °C. Subsequently, diethoxymethane (35.21 mL) was added slowly and the reaction mixture was warmed up to 100 °C (internal temperature) and kept for 18 hours. Upon completion of the reaction, the mixture was cooled and poured into acetone (410 mL) and a brown powder was precipitated. The product composition was analyzed by 1H NMR to give cucurbit[5]uril (8%), cucurbit[6]uril (42%), cucurbit[7]uril (43%), cucurbit[8]uril (7%), cucurbit[9]uril (0%), cucurbit[10]uril (0%) and cucurbit[13]uril (0%). In addition, the residual formaldehyde content was 34 ppm by HPLC. | | in vivo | Cucurbit[8]uril shows a very low toxicity of the in vivo intravenous injection, as well as oral administration studies on mice[2]. | | References | [1] Patent: WO2018/115822, 2018, A1.
