Researchers at the National Cancer Institute (NCI) have developed aryl hydantoin heterocycles that target the androgen receptor (AR). NCI seeks research co-development partners and/or licensees to develop these compounds as therapeutics for prostate cancer. As these compounds consist of both AR agonists and antagonists, they may also be effective therapeutics for androgen dysfunctional disorders, such as androgen deficiency disorders or hyperandrogenism.
