In order to determine the nature of the human embryo, we need to know its biological, anthropological, philosophical, and even its legal reality. In our opinion, however, the anthropological, philosophical and legal reality of the embryo — the basis of its human rights — must be built upon its biological reality (see also HERE).

CONTEXT Mifepristone (RU 486) blocks the action of cortisol by binding to the glucocorticoid receptor and, therefore, is of potential therapeutic value in Cushing's syndrome. However, research in endogenous hypercortisolism has been hampered by the controversy related to the use of mifepristone for inducing abortion. Currently, new studies are planned to better define the role of RU 486 in Cush...

Reversal of multidrug resistance by RU 486.

P-Glycoproteins represent a family of drug efflux proteins that convey multidrug resistance to cells in which they are expressed. This phenomenon can lower the efficacy of drugs used in chemotherapy. The steroid progesterone has been shown to bind P-glycoproteins and inhibit their drug efflux. We report that the antiprogestin RU 486 can reverse multidrug resistance in cells overexpressing the m...

Mifepristone (ru-486) and Its Analogues

Mifepristone (RU-486) is the first antiprogesterone drug used for the termination of early pregnancies (6 to 8 weeks pregnancies), a steroid synthesized in the laboratory. It has higher affinity for the progesterone receptor. It also has other potential applications as anticancer and glucocorticoid antagonist. It is desirable to increase its antiprogestational potency and eliminate the antigluc...
