Esaxerenone (INN) (brand name Minnebro; developmental code names CS-3150, XL-550) is a nonsteroidal antimineralocorticoid which was discovered by Exelixis and developed by Daiichi Sankyo Company and is approved in Japan for the treatment of hypertension. [1] [2] [3] It acts as a highly selective silent antagonist of the mineralocorticoid receptor (MR), the receptor for aldosterone, with greater than 1,000-fold selectivity for this receptor over other steroid hormone receptors, and 4-fold and 76-fold higher affinity for the MR relative to the existing antimineralocorticoids spironolactone and eplerenone. [1] [2] [3] As of January 2019, esaxerenone is in phase III clinical trials for diabetic nephropathies. [1]
An antimineralocorticoid, also known as a mineralocorticoid receptor antagonist or aldosterone antagonist, is a diuretic drug which antagonizes the action of aldosterone at mineralocorticoid receptors. This group of drugs is often used as adjunctive therapy, in combination with other drugs, for the management of chronic heart failure. Spironolactone, the first member of the class, is also used in the management of hyperaldosteronism and female hirsutism. Most antimineralocorticoids, including spironolactone, are steroidal spirolactones. Finerenone is a nonsteroidal antimineralocorticoid.
Eplerenone, sold under the brand name Inspra, is an aldosterone antagonist type of potassium-sparing diuretic that is used to treat chronic heart failure and high blood pressure, particularly for patients with resistant hypertension due to elevated aldosterone. It is a steroidal antimineralocorticoid of the spirolactone group and a selective aldosterone receptor antagonist (SARA). Eplerenone is more selective than spironolactone at the mineralocorticoid receptor relative to binding at androgen, progestogen, glucocorticoid, or estrogen receptors.
Telapristone (INN), as telapristone acetate, is a synthetic, steroidal selective progesterone receptor modulator (SPRM) related to mifepristone which is under development by Repros Therapeutics for the treatment of breast cancer, endometriosis, and uterine fibroids. It was originally developed by the National Institutes of Health (NIH), and, as of 2017, is in phase II clinical trials for the aforementioned indications. In addition to its activity as an SPRM, the drug also has some antiglucocorticoid activity.
Trimegestone, sold under the brand names Ondeva and Totelle among others, is a progestin medication which is used in menopausal hormone therapy and in the prevention of postmenopausal osteoporosis. It was also under development for use in birth control pills to prevent pregnancy, but ultimately was not marketed for this purpose. The medication is available alone or in combination with an estrogen. It is taken by mouth.
An orexin receptor antagonist, or orexin antagonist, is a drug that inhibits the effect of orexin by acting as a receptor antagonist of one or both of the orexin receptors, OX1 and OX2. Medical applications include treatment of sleep disorders such as insomnia.
A nonsteroidal antiandrogen (NSAA) is an antiandrogen with a nonsteroidal chemical structure. They are typically selective and full or silent antagonists of the androgen receptor (AR) and act by directly blocking the effects of androgens like testosterone and dihydrotestosterone (DHT). NSAAs are used in the treatment of androgen-dependent conditions in men and women. They are the converse of steroidal antiandrogens (SAAs), which are antiandrogens that are steroids and are structurally related to testosterone.
Seviteronel is an experimental cancer medication which is under development by Viamet Pharmaceuticals and Innocrin Pharmaceuticals for the treatment of prostate cancer and breast cancer. It is a nonsteroidal CYP17A1 inhibitor and works by inhibiting the production of androgens and estrogens in the body. As of July 2017, seviteronel is in phase II clinical trials for both prostate cancer and breast cancer. In January 2016, it was designated fast-track status by the United States Food and Drug Administration for prostate cancer. In April 2017, seviteronel received fast-track designation for breast cancer as well.
Erteberel is a synthetic, nonsteroidal estrogen which acts as a selective ERβ agonist and is under development by Eli Lilly for the treatment of schizophrenia. It is specifically under investigation for the treatment of negative symptoms and cognitive impairment associated with the condition. As of 2015, it is in phase II clinical trials for this indication in the United States. Erteberel was also under investigation for the treatment of benign prostatic hyperplasia and reached phase II clinical studies for this use but failed to improve symptoms in men with the condition and development for this indication was discontinued. The drug has also been proposed as a potential novel treatment for glioblastoma.
SERBA-2, short for selective estrogen receptor beta agonist-2, is a synthetic, nonsteroidal estrogen which acts as a selective ERβ agonist. For the ERα and ERβ, SERBA-2 has affinities (Ki) of 14.5 nM and 1.54 nM, efficacies of 85% and 100%, and EC50 values of 85 nM and 3.61 nM, respectively, demonstrating 9-fold binding selectivity and 11-fold functional selectivity for the ERβ over the ERα. An enantiomer of SERBA-2, erteberel (SERBA-1), is more potent and selective in comparison and is under development for the treatment of schizophrenia.
Vilaprisan is a synthetic and steroidal selective progesterone receptor modulator (SPRM) which is under development by Bayer HealthCare Pharmaceuticals for the treatment of endometriosis and uterine fibroids. It is a potent and highly selective partial agonist of the progesterone receptor (PR). As of 2017, the drug is in phase II clinical trials for the aforementioned indications.
Lonaprisan is a synthetic, steroidal antiprogestogen which was under development by Bayer HealthCare Pharmaceuticals for the treatment of endometriosis, dysmenorrhea, and breast cancer but was discontinued. It is a potent and highly selective silent antagonist of the progesterone receptor (PR). The drug reached phase II clinical trials prior to its discontinuation.
Apararenone (INN) is a nonsteroidal antimineralocorticoid which is under development by Mitsubishi Tanabe Pharma for the treatment of diabetic nephropathies and non-alcoholic steatohepatitis. It was also previously being developed for the treatment of hypertension, but development was discontinued for this indication. Apararenone acts as a highly selective antagonist of the mineralocorticoid receptor, the receptor for aldosterone. As of 2017, it is in phase II clinical trials.
Dagrocorat is a nonsteroidal but steroid-like selective glucocorticoid receptor modulator (SGRM) which was under development for the treatment of rheumatoid arthritis but was never marketed. It is described as a partial agonist and "dissociable" agonist of the glucocorticoid receptor. The drug reached phase I clinical trials prior to the discontinuation of its development. The C2α dihydrogen phosphate ester of dagrocorat, fosdagrocorat, was also under investigation, but its development was terminated as well.
Fosdagrocorat is a nonsteroidal but steroid-like selective glucocorticoid receptor modulator (SGRM) which was under development for the treatment of rheumatoid arthritis but was never marketed. It is the C2 dihydrogen phosphate ester of dagrocorat, and acts as a prodrug of dagrocorat with improved pharmacokinetics. The drug reached phase II clinical trials prior to the discontinuation of its development.
