Tanaproget (INN; developmental code names NSP-989, WAY-166989) is an investigational nonsteroidal progestin.[1] It is a high affinity, high efficacy, and very selective agonist of the progesterone receptor (PR).[1] Due to its much more selective binding profile relative to most conventional, steroidal progestins, tanaproget may prove to produce fewer side effects in comparison.[1] As of December 2010,[2] it is in phase II clinical trials in the process of being developed for clinical use as a contraceptive by Ligand Pharmaceuticals.[3][4]
An analog of tanaproget, 4-fluoropropyltanaproget (18F), has been developed as a radiotracer for imaging of the PR in positron emission tomography.[5]
