Orientin promotes diabetic wounds healing by suppressing ferroptosis via activation of the Nrf2/GPX4 pathway.

Diabetic patients often experience delayed wound healing due to impaired functioning of human umbilical vein endothelial cells (HUVECs) under high glucose (HG) conditions. This is because HG conditions trigger uncontrolled lipid peroxidation, leading to iron-dependent ferroptosis, which is caused by glucolipotoxicity. However, natural flavonoid compound Orientin (Ori) possesses anti-inflammatory bioactive properties and is a promising treatment for a range of diseases.

Sipeimine ameliorates osteoarthritis progression by suppression of NLRP3 inflammasome-mediated pyroptosis through inhibition of PI3K/AKT/NF-κB pathway: An in vitro and in vivo study.

Background: Osteoarthritis (OA) is a chronic and degenerative condition that persists and progresses over time. Sipeimine (Sip), a steroidal alkaloid derived from , has attracted considerable attention due to its exceptional anti-inflammatory, analgesic, antioxidant, and anti-cancer characteristics. However, Sip's effects on OA and its mechanism still need further research.
