INTRODUCTION: The pharmacological target for progesterone, different progestins, and Selective Progesterone Receptor Modulators (SPRMs) is the nuclear progesterone receptor (PR). EC313 is a new member of a subgroup of SPRMs, mesoprogestins,…

Selective progesterone receptor modulators (SPRMs) represent a new class of progesterone receptor ligands that exert clinically relevant tissue-selective progesterone agonist, antagonist, partial, or mixed agonist/antagonist effects on vari…

BACKGROUND: Asoprisnil (J867) is a novel selective progesterone receptor modulator (SPRM) that exhibits partial agonist and antagonist activities and tissue selective effects. This double-blind, dose-escalation study was conducted to evalua…

Asoprisnil is a novel selective steroid receptor modulator that shows unique pharmacodynamic effects in animal models and humans. Asoprisnil, its major metabolite J912, and structurally related compounds represent a new class of progesteron…

Endometriosis, the presence of endometrial tissue outside the uterus, is a progressive, estrogen-dependent disease and occurs nearly exclusively in menstruating women of reproductive age. Pain syndrome, however, represents the major clinica…

Dienogest is the first non-alkylated 19-norprogestin on the market. This so-called hybrid progestin combines the typical qualities of the modern 19-norprogestins with those of natural progesterone and synthetic hydroxyprogesterone derivativ…

The strong hepatic estrogenic actions of ethinylestradiol (EE) are very likely to be the cause of the cardiovascular morbidity related to the use of combined oral contraceptives (COCs). This survey presents results of EE replacement in COCs…

Mifepristone (RU 486), used clinically for the termination of early pregnancy, and its acetyl and 13-retro (13 alpha) analogs show potent antiproliferative effects against estrogen-dependent human breast tumors and endometriosis. However, t…

There is evidence from previous studies that progesterone antagonists (antigestagens) modify estrogen responses at endometrial and myometrial levels without having affinity to the estrogen receptor (ER). The purpose of the present study was…
