Diterpenoid Diversity across Land Plants
Helvetica Chimica Acta, EarlyView.Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Macromolecular Rapid Communications, EarlyView.Little is known about the cellular uptake of single chain nanoparticles that are cross‐linked with dynamic bonds. Using Förster resonance energy transfer and fluorescence lifetime imaging microscopy (FRET‐FLIM) the dynamic nature of the bonds is seen, in which the interaction between two peptides, disassemble quickly, relatively.

Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer
Medicine Bulletin, EarlyView.ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...
