This invention provides a class of androgen receptor targeting agents
(ARTA). The agents define a new subclass of compounds, which are
selective androgen receptor modulators (SARM). Several of the SARM
compounds have been found to have an unexpected androgenic and anabolic
activity of a nonsteroidal ligand for the androgen receptor. Other SARM
compounds have been found to have an unexpected antiandrogenic activity
of a nonsteroidal ligand for the androgen receptor. The SARM compounds,
either alone or as a composition, are useful for a) male contraception;
b) treatment of a variety of hormone-related conditions, for example
conditions associated with Androgen Decline in Aging Male (ADAM), such as
fatigue, depression, decreased libido, sexual dysfunction, erectile
dysfunction, hypogonadism, osteoporosis, hair loss, anemia, obesity,
sarcopenia, osteopenia, osteoporosis, benign prostate hyperplasia,
alterations in mood and cognition and prostate cancer; c) treatment of
conditions associated with Androgen Decline in Female (ADIF), such as
sexual dysfunction, decreased sexual libido, hypogonadism, sarcopenia,
osteopenia, osteoporosis, alterations in cognition and mood, depression,
anemia, hair loss, obesity, endometriosis, breast cancer, uterine cancer
and ovarian cancer; d) treatment and/or prevention of acute and/or
chronic muscular wasting conditions; e) preventing and/or treating dry
eye conditions; f) oral androgen replacement therapy; g) decreasing the
incidence of, halting or causing a regression of prostate cancer; and/or
h) inducing apoptosis in a cancer cell.
