Biological Activity
SW033291 is an inhibitor of the prostaglandin-degrading enzyme 15-PGDH. PGE2 is known to promote hematopoiesis and to promote reeneration by causing stem cells to proliferate. 15-PGDH degrades prostaglandin PGE2 and is a negative regulator of tissue regeneration and repair. SW033291 inhibition of 15-PGDH doubled levels of PGE2 and doubled rates of colon and liver tissue regeneration. Mice given SW033291 after receiving a bone marrow transplant had a two- to threefold increase in the number of donor cells th at homed to the their bone marrow.
