| Description: | This Example provides data on two groups (Table 1 and Table 2) of structural analogues of identified 15-PGDH inhibitors. Data provided is the IC50 of each compound for inhibiting enzymatic activity of recombinant 15-PGDH in an in vitro assay. Recombinant 15-PGDH is human unless otherwise specified. 15-PGDH inhibitors described herein can provide a pharmacologic method for elevating prostaglandin levels in tissue. Known activities of prostaglandins include promoting hair growth, promoting skin pigmentation, and promoting skin darkening or the appearance of skin tanning. Known activities of prostaglandins also include ameliorating pulmonary artery hypertension. 15-PGDH inhibitors described herein may also be utilized to increase tissue stem cell numbers for purposes that would include increasing resistance to tissue damage by radiation, increasing resistance to environmental exposures to radiation, increasing stem cell numbers to increase fitness of bone marrow or other types of transplantation (through either in vivo exposure to 15-PGDH inhibitors described herein to increase stem cell numbers prior to harvest of a transplanted tissue, or through ex vivo exposure of a harvested tissue prior to transplant into a recipient host, or through treatment of the graft recipient). |
