Biosynthesis of Flavonoids [PDF]
SEVERAL workers have shown that lignin and the ‘B ring’ of flavonoids are formed in vivo from shikimic acid and certain C6C3 compounds. The latter compounds are frequently encountered in plant tissues1. The ‘A ring’ of flavonoids appears to arise from acetate units2.

Bioactivity and mechanisms of flavonoids in decreasing insulin resistance
Flavonoids are ubiquitous compounds in nature and are found in many Chinese herbal medicines. Due to their biological activity, flavonoids show potential for decreasing insulin resistance (IR), thereby delaying the progression of diabetes and ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Reversal of Multidrug Resistance in Cancer by Multi-Functional Flavonoids
Multidrug resistance (MDR) resulting from different defensive mechanisms in cancer is one of the major obstacles of clinical treatment. To circumvent MDR many reversal agents have been developed, but most of them fail in clinical trials due to severely ...

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...
