CAY10410 is an analog of prostaglandin D₂/prostaglandin J₂ (PGD₂/PGJ₂) with structural modifications intended to give it PPARγ ligand activity and resistance to metabolism. 15-deoxy-Δ^12,14-PGJ₂ has been shown to be a potent ligand for PPARγ.¹ Metabolism of the cyclopentenone prostaglandins PGA₂, PGJ₂, and Δ¹²-PGJ₂ occurs via glutathione addition across the α,β unsaturated enone.² CAY10410 was designed as an analog of the PPARγ-binding prostaglandins which could not undergo this conjugation reaction. In human neuroblastoma SH-SY5Y cells, CAY10410 was not cytotoxic at up to 25 μM. It also failed to covalently modify thioredoxin or induce oxidative stress at 50 μM.³
