Abstract:
1. A method for promoting or stimulating pigmentation of the skin and/or skin appendages and/or limiting depigmentation and/or whitening of the skin and/or skin appendages, comprising administering to a mammalian organism in need of such treatment, a thus effective amount of at least one inhibitor of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) of formula (I), or a salt thereof: in which: Hy is a heterocycle having 4, 5, 6 or 7 atoms, optionally comprising at least one carbonyl function and/or one thiocarbonyl function, said heterocycle being optionally substituted with at least one substituent selected from the group consisting of a halogen, the groups OR, SR, NRR′, COR, CSR, NRCONR′R″, C(═NR)R′, C(═NR)NR′R″, NRC(═NR′)NR″R′″, OCOR, COSR, SCOR, CSNRR′, NRCSR′, NRCSNR′R″, COOR, CONRR′, CF G is S, R wherein said inhibitor also has prostaglandin synthase-inhibiting activity, and the ratio of the 15-PGDH-inhibiting activity of said at least one inhibitor of 15-PGDH to the prostaglandin synthase-inhibiting activity thereof is greater than 1.
