From Painkillers to Antidiabetics: Structural Modification of NSAID Scaffolds for Drug Repurposing

The treatment of diabetes in the modern era, with its growing patient population, represents a significant challenge due to the wide range of adverse effects associated with medications that target complex biochemical processes. Consequently, researchers are investigating the hypoglycemic potential of existing drugs. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain, fever, and various inflammatory conditions. Recent studies have shown that NSAIDs, particularly salicylates, can influence glycemia through multiple mechanisms, including inhibition of gastrointestinal enzymes, blockade of KATP channels, activation of AMP-activated protein kinase (AMPK), and inhibition of NF-κB signaling, among others. Accordingly, this review explores the hypoglycemic potential of NSAIDs as well as their derivatives, and the diverse mechanisms through which these molecules may influence glucose homeostasis.
