Prostaglandins have a short life in vivo because NAD⁺-dependent 15-hydroxy prostaglandin dehydrogenase (15-PGDH) catalyzes their oxidation to 15-keto metabolites with greatly reduced biological activity.¹ Thiazolidinediones (TZDs) are a class of PPARγ agonists that have potent 15-PGDH inhibitory activity.^2,3 CAY10638 is a TZD derivative that inhibits 15-PGDH activity with an IC₅₀ value of 31 nM.³

ChEBI: CAY10638 is an aromatic ether.
