Bioactivity | SW033291 is a potent and high-affinity inhibitor of 15-PGDH with a Ki of 0.1 nM. SW033291 increases prostaglandin PGE2 levels in bone marrow and other tissues. SW033291 also promotes tissue regeneration[1]. | ||||||||||||
Target | Ki: 0.1 nM (15-PGDH) | ||||||||||||
Invitro | Treating cells with SW033291 decreases cellular 15-PGDH enzyme activity by 85%. SW033291 inhibition of 15-PGDH was non-competitive versus PGE2 over concentrations up to 40 μM PGE2. Treatment of A549 cells with SW033291 increases PGE2 levels by 3.5-fold at 500 nM, with an EC50 50 at approximately 75 nM[1]. | ||||||||||||
In Vivo | SW033291 (10 mg/kg; intraperitoneal injection; twice daily; for 3 days; C57BL/6J mice) treatment for three consecutive days shows significant benefits, including a doubling of peripheral neutrophil counts, a 65% increase in marrow SKL cells, and a 71% increase in marrow SLAM cells[1].
