This review article examines the development and current status of non-steroidal ligands for the progesterone receptor, contrasting them with traditional steroidal progestins that often exhibit cross-reactivity with other steroid receptors. The authors highlight these new chemical entities as promising tools for contraception and various therapeutic indications due to their specificity. The paper outlines the potential advantages of avoiding off-target effects associated with steroidal backbones while discussing the emerging landscape of these specific antagonists and agonists. Relevance to endometriosis: listed as one indication for GnRH antagonists, though the paper's main focus is uterine fibroids.

Abstract

The nuclear receptor for progesterone is a target for contraception and for several therapeutic indications. Progestin agonists and antagonists in clinical use mimic the steroidal backbone of the cognate ligand, progesterone. Thus, they have significant cross-reactivity with other steroid receptors. Recently, non-steroidal progesterone receptor ligands have begun to appear in the literature. This review will describe the current status of research into these promising new chemical entities.
