| Description | Cucurbit[8]uril is a highly effective and safe supramolecular compound that promotes protein heterodimerization. It selectively induces the heterodimerization of methylviologen and naphthalene functionalized proteins, demonstrating its specificity and versatility. Additionally, Cucurbit[8]uril shows exceptional oral activity and low toxicity, making it a promising candidate for various pharmaceutical and biotechnological applications. |
| In vitro | Cucurbit[8]uril (0~20 μM; 48 hours; CHO-K1 cells) makes the relative cell viability dropped marginally to 86%[2].Cucurbit[8]uril indeed selectively induces the heterodimerization of MV-eYFP with Np-eCFP. Cucurbit[8]uril-induced high energy transfer between the proteins is only observed in the presence of all three supramolecular components, allowing the formation of the ternary complex. In the presence of Cucurbit[8]uril, the unspecific protein assembly induced by the methylviologen is inhibited. The ternary system of Cucurbit[8]uril with methylviologen (MV) and naphthalene (NP) can also be successfully used for the formation of selective protein heterodimers of more hydrophobic proteins. The presence of Cucurbit[8]uril as a host molecule is required to prevent MV induced unspecific dimerization with hydrophobic protein surfaces[1]. |
| 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]. |
