Abstract BACKGROUND: A number of synthetic steroids are capable of modulating progesterone receptors with a spectrum of activities ranging from pure antagonism to a mixture of agonism and antagonism. The best known of these are mifepristone (RU 486), asoprisnil (J 867), onapristone (ZK 98299), ulipristal (CDB 2914), Proellex() (CDB 4124), ORG 33628 and ORG 31710. OBJECTIVE: Outside reproduction selective modulators of progesterone receptors have been under investigation for a large variety of indications, for example in oncology as adjuvants in breast, cervical, endometrial, ovarian and prostate cancer, as well as inoperable meningioma and leiomyosarcoma. In addition, they have been used as antiglucocorticoids. It is therefore useful to review the results obtained in these conditions. METHODS: A careful evaluation of existing major review papers and of recently published articles was carried out for the indications under review, focusing not only on mifepristone but also on those other selective modulators of progesterone receptors for which data are available. RESULTS/CONCLUSIONS: In preliminary studies selective modulators of progesterone receptors had some activity on a number of neoplasias. Their antiglucocorticoid activity has been tested with some success in Cushing's syndrome, several psychiatric conditions (e.g., mood disorders and Alzheimer's disease) and acute renal failure. Finally they are being used in a gene regulator system. This article was published in Expert Opin Pharmacother and referenced in Journal of Cancer Science & Therapy
