This paper explores how ฮฒ-cyclodextrin can host MPPC, the active principle of Minoxicapilยฎ, a topical treatment relevant to alopecia, and how this supramolecular interaction may support the design of more aqueous and skin-compatible formulations.
In order to demonstrate this, the authors combined NMR and ROESY experiments, molecular docking, molecular dynamics simulations, umbrella sampling, membrane diffusion studies, and in vitro assays on human dermal papilla cells.
And the main findings? They point to a selective and stable hostโguest interaction:
๐งช ฮฒ-cyclodextrin forms a 1:1 inclusion complex with MPPC;
๐งฌ the cationic component of MPPC is preferentially included in the ฮฒ-cyclodextrin cavity;
โ๏ธ the pyrrolidinyl moiety drives complex formation through hydrophobic interactions;
๐ง the counterion remains mainly solvated rather than trapped inside the cavity;
๐งซ MPPC-ฮฒ-CD shows favorable in vitro biocompatibility and enhanced dermal papilla cell proliferation;
๐งด diffusion studies suggest low systemic exposure, supporting its relevance for topical applications.
