High-throughput screening identifies FDA approved drug mitiglinide as a novel pyroptosis inhibitor and therapeutic agent for osteoarthritis

Mitiglinide, identified via FDA-drug-library screening, alleviates OA progression by suppressing NLRP3 inflammasome activation and ECM degradation via activation of the Nrf2/HO-1 signaling pathway. This positions mitiglinide as a repurposed disease-modifying OA drug candidate.
