Biological Activity
SW033291 is a small-molecule inhibitor of 15-PGDH (Ki=0.1 nM) that increases prostaglandin PGE2 levels in bone marrow and other tissues.
In Vitro
SW033291 inhibition of 15-PGDH was noncompetitive versus PGE2 over concentrations up to 40 μM PGE2. SW033291 also demonstrated selective high-affinity interaction with 15-PGDH in thermal denaturation assays. Treatment of A549 cells with SW033291 increased PGE2 levels by 3.5-fold at 500 nM, with 50% of maximal stimulation (EC50) at ~75 nM [1].
In Vivo
mice injected with SW033291 closely phenocopied 15-PGDH knockout mice, with 10 mg per kg of weight (mg/kg) SW033291 inducing a twofold increase in PGE2 levels in bone marrow, colon, lung, and liver. Mice injected with SW033291 at 20 mg/kg daily for 7 days showed equivalent daily weights and activity as mice injected with vehicle-control and showed no adverse changes in blood counts or serum chemistry [1].
