Recently, a new class (often referred to as SPRMs: selective progesterone receptor modulators) of progesterone receptor ligands with mixed agonist/antagonist properties has been described. Such compounds are envisaged, for example, as treatment for endometriosis, uterine fibroids, and leiomyomas. Existing SPRMs include Asoprisnil 1 and Uliprisnil acetate 2. In our hands, however, these compounds proved to have a predominantly or exclusively antagonistic in vitro profile, which may make this type of compound less attractive, for example, as contraceptives. We therefore aimed at a class of mixed-profile compounds that would show a more evenly balanced agonist/antagonist profile. A novel class of 11 beta-[4-(heteroaryl)phenyl]-substituted pregnanes was identified that displayed the desired balance. Contrary to known SPRMs, this novel class of MPP (mixed-profile progestagen) was found to have a truly mixed activity, including a sizeable agonist component. (C) 2008 Elsevier Ltd.
