Researchers from Gansu University of Chinese Medicine synthesized nitroxide radical–modified rhein derivatives to target the Keap1-Nrf2 antioxidant pathway. Among them, compound 4b displayed potent DPPH and ABTS free radical scavenging, protected L02 hepatocytes under oxidative stress, and extended Caenorhabditis elegans lifespan by over 40%, enhancing stress tolerance and antioxidant enzyme activity.

Key points

• Design and synthesis of rhein nitroxide derivatives via DCC/DMAP coupling at the 3-carboxyl position.
• Compound 4b exhibits IC₅₀ values of 0.51 mM (DPPH) and 0.12 mM (ABTS) and restores 95.4% viability in H₂O₂-challenged L02 hepatocytes.
• In C. elegans, 300 µM 4b increases mean lifespan by 41%, enhances stress resistance, reduces ROS/MDA, and elevates GSH levels.

Why it matters: This derivative offers a novel, targeted Keap1-Nrf2 modulation approach with strong anti-aging potential and improved antioxidant activity.

RenewalBio, a spin-out from Professor Jacob Hanna’s lab at the Weizmann Institute, develops a novel bio-manufacturing platform using stembroids—lab-grown embryo-like models derived from human pluripotent stem cells. By cultivating these structures up to day 14, RenewalBio harnesses natural differentiation to produce young, patient-matched blood cells intended for bone marrow failure therapy, potentially advancing regenerative transplantation and longevity applications.

Key points

• Generation of human stembroids from pluripotent stem cells mimics day 14 embryonic development.
• Production of autologous young blood cells targets bone marrow failure without donor dependence.
• Platform yields multiple cell types—endothelial, neuronal, pancreatic, liver—for broad regenerative applications.

Why it matters: This stembroid-based method establishes a scalable, patient-specific source of high-quality cells, promising safer and more effective regenerative therapies.
