Structural Basis for the Inhibitory Effects of a Novel Reversible Covalent Ligand on PPARγ Phosphorylation: A Journey Through the Molecular Desert

Peroxisome proliferator-activated receptor γ (PPARγ), a key regulator of glucose metabolism, is a promising target for developing new antidiabetic drugs. However, traditional PPARγ agonists, like a mirage in the desert of diabetes research, often come with undesirable side effects. This research delves into the molecular mechanisms of PPARγ phosphorylation, exploring a new approach for selectively inhibiting this process without the unwanted side effects associated with traditional agonists. The authors developed SB1495, a novel reversible covalent inhibitor of Cdk5-mediated phosphorylation of PPARγ at Ser245, a crucial site for insulin-sensitizing effects. They determined the crystal structure of PPARγ in complex with SB1495 and its enantiomeric analogue SB1494, providing a detailed molecular map of how these inhibitors interact with PPARγ. Their findings reveal that SB1495, like a skilled traveler carefully navigating a treacherous desert path, binds to a specific region of PPARγ, blocking phosphorylation and potentially offering a new avenue for treating type 2 diabetes.
