What is STK393606?

Description

15-hydroxy prostaglandin dehydrogenase (15-hydroxy PGDH) is a key enzyme involved in the inactivation of PGs and related eiscosanoids. It functions by catalyzing the oxidation of primary PGs to their 15-keto metabolites. Two types of 15-hydroxy PGDH have been identified: type-I is NAD⁺-dependent primarily using eicosanoids as substrates, while type-II uses either NAD⁺ or NADP⁺ as cofactors and bears broader substrate specificity. STK393606 is a competitive inhibitor of NAD⁺-dependent type-I 15-hydroxy PGDH with an IC₅₀ value of 26.4 nM and a K_i value of 5 nM. It demonstrates selectivity for 15-hydroxy PGDH when profiled across a panel of related dehydrogenase or reductase enzymes.
