Moth-eye nanostructures, known for their biological antireflective properties, are formed by a self-assembly mechanism. Understanding and replicating this mechanism on artificial surfaces open avenues for the engineering of bioinspired multifunctional nanomaterials. Analysis of corneal nanocoatings from butterflies of the genus reveals a variety of nanostructures with uniformly strong antiwetting properties accompanied by varying antireflective functionalities.

Selective inhibitors of Frizzled (FZD) GPCRs are highly sought after as potentially highly efficacious and safe treatments for cancer as well as tools in regenerative medicine and fundamental science. In recent years, there have been several reports claiming the identification of small molecule agents that are selective toward certain FZD proteins using a variety of approaches. However, the majority of these studies lacked a selective functional assay to validate their functionality.

Artificial bio-nanocoatings, primarily composed of proteins, offer a broad range of applications across various fields thanks to their unique properties. Proteins, as major components of these structures, enable a high degree of customization, such as mutations, conjugation with other molecules or nanoparticles, or the inclusion of an enzymatic activity. Their ability to self-assembly simplifies the production of bio-nanocoatings, making this process efficient and environment-friendly.

Article Synopsis
  • A detailed metabolite profiling of a medicinal plant using UHPLC-ESI-MS/MS was performed for the first time, identifying 71 compounds, mostly flavonoids, triterpene glycosides, and ecdysteroids.
  • The compounds schaftoside, 26-hydroxyecdysone, and silviridoside were highlighted as important markers for evaluating preparation quality.
  • The methanol extract demonstrated cytotoxic and Wnt pathway-inhibiting effects against triple-negative breast cancer, identifying 2-Deoxy-20-hydroxyecdysone as potent, while the presence of a hydroxyl group at C-2 in ecdysteroids was linked to reduced cytotoxicity against cancer cells.
