Precise delivery of hydrophobic drugs has always been a great challenge for drug delivery systems. To overcome this problem, we designed and synthesized a novel supramolecular host biotin-acyclic cucurbituril (ACBB) at the first time, and we have developed a host-guest amphiphilic complex based on ACBB and amantadine-conjugated cannabinoids (AD-CBD) that self-assembles to form functionalized supramolecular micelles (FSMs) for cell-targeted drug delivery. The 1:1 stoichiometric ratio of the amphiphilic complex and its possible host-guest inclusion behaviors are obtained by fluorescence titration, nuclear magnetic resonance (NMR), Fourier transform-infrared spectroscopy (FT-IR) and thermal analysis (TGA and DSC).

Cannabidiol (CBD) is one specific kind of the cannabinoid in with a wide range of pharmacological activities. However, the poor water solubility and specificity of CBD limits its application in pharmaceutical field. For solving these problems, in this work, we successfully prepared a targeted carrier by grafting biotin (BIO) onto ethylenediamine-β-Cyclodextrin (EN-CD) in a single step to generate a functionalized supramolecule, named BIO-CD.

To display the capability of the phenolic acid nutraceutical ferulic acid (FLA) in optimizing the in vitro/in vivo properties of the antiviral drug amantadine hydrochloride (AMH) and achieve synergistically enhanced antiviral effects, thereby gaining some new insights into pharmaceutical cocrystals of antiviral drugs with phenolic acid nutraceuticals, a cocrystallization strategy of dual optimization was created. Based on this strategy, the first drug-phenolic acid nutraceutical cocrystal of AMH with FLA, namely AMH-FLA-H2O, was successfully assembled and completely characterized by employing single-crystal X-ray diffraction and other analytical techniques. The cocrystal was revealed to be composed of AMH, FLA, and water molecules in the ratio of 3 : 1 : 1.

Protein-protein interactions drive self-assembly of biomacromolecules and thus enable important physiological functions at a cellular level. Supramolecular chemists have developed artificial host-guest interactions that are similar with, yet distinct from and orthogonal to, the natural protein-protein interactions. For instance, cucurbit[]urils are synthetic receptors that can specifically recognize proteins with N-terminal aromatic residues with high affinities, yet this interaction can be reversed by the competition of small molecules such as amantadine.
