Lippia umbellata Cav.: Chemical Composition, Insecticidal, and Antimicrobial Activities. [PDF]

Chem Biodivers
Hexane extracts of Lippia umbellata leaves and flowers contain lupenone, α‐amyrin, and hentriacontane. They exhibit insecticidal activity against Drosophila melanogaster and inhibit AChE in vitro and in silico. Furthermore, the extracts can inhibit the growth of medically important bacteria and yeasts, including multidrug‐resistant strains.

Encapsulin-Protected Immunotherapeutic Complexes: Bacteria-Derived Nanoparticles for mRNA Delivery to Eukaryotic Cells. [PDF]

ChemMedChem
Here, we introduce a biological, self‐assembling supramolecular nanoparticle designed to encapsulate eukaryotic‐expressible mRNA within an encapsulin shell via an encapsulin‐RNA adaptor peptide (ERAP). This process occurs in bacteria, and the resulting complex can deliver its mRNA into eukaryotic cells, where it is expressed.
